Precision’s Prolific, Persistent Progression

The Italian industrial machinery specialist Pomini Tenova has achieved a significant milestone in its long standing partnership with Vietnam’s Hoa Phat Group. The company recently shipped its 15th roll grinder to the Southeast Asian steel giant, marking nearly two decades of technological collaboration. Roll grinders represent essential equipment for modern steel mills, maintaining the cylindrical precision of work rolls & backup rolls used in hot and cold rolling mills. Without regular grinding, rolls develop surface defects, uneven wear patterns, and dimensional inaccuracies that compromise finished steel quality. Pomini Tenova, headquartered near Milan, has supplied roll grinding technology to Hoa Phat since the Vietnamese company’s early expansion phases. A company spokesperson noted that each successive grinder incorporates improved automation, higher material removal rates, and better surface finish capabilities compared to previous models. The 15th unit belongs to Pomini Tenova’s latest generation series, featuring computer numerical control systems that measure roll geometry during the grinding process, adjusting parameters automatically to achieve tolerances measured in microns. Hoa Phat operates multiple production facilities across Vietnam, including the massive Dung Quat steel complex in Quảng Ngãi province. This complex represents the country’s largest integrated steel mill, capable of producing hot rolled coil, construction steel, and steel billet for domestic consumption and export markets.

Hoa Phat’s Hegemony & Hardware Hunger

Hoa Phat Group has transformed from a domestic construction steel supplier into Vietnam’s undisputed steel champion. The company now accounts for roughly 30% of Vietnam’s total steel market, producing over 8 million metric tons annually across its facilities. Its Dung Quat 2 expansion, scheduled for completion in 2025, will add another 5.6 million metric tons of hot rolled coil capacity, pushing total output beyond 14 million metric tons. This aggressive growth trajectory demands corresponding investments in support equipment like roll grinders. Each rolling mill line requires regular roll changes, typically every few hundred to several thousand metric tons of production depending on product type and roll material. A single large rolling mill may contain dozens of rolls, each requiring grinding every few days or weeks. Hoa Phat’s procurement of 15 roll grinders from Pomini Tenova reflects both the scale of its operations and the trust placed in Italian grinding technology. The Vietnamese steelmaker previously sourced roll grinding equipment from German and Japanese suppliers but has standardised on Pomini Tenova for recent expansions. Industry analysts attribute this choice to Pomini Tenova’s superior automation software and faster service response times compared to Asian competitors. The 15th grinder will likely serve Hoa Phat’s new wide hot strip mill, which produces coil up to 2,000 millimeters wide for automotive, pipe making, and construction applications.

Tenova’s Technological Tenacity Triumphs

Pomini Tenova operates as a brand within the Tenova group, a global supplier of advanced technologies for the metals and mining industries. Tenova itself forms part of Techint Group, an Italian Argentine conglomerate with significant steelmaking, engineering, and energy interests. Pomini Tenova’s roll grinding machines incorporate proprietary measurement systems that evaluate roll roundness, surface roughness, and dimensional accuracy during the grinding cycle. The company’s latest grinders achieve surface finishes below 0.1 micrometres Ra, meaning the average deviation from perfect smoothness measures less than one ten thousandth of a millimetre. Such precision directly translates to better steel surface quality, reducing defects like scratches, ripples, and thickness variations in finished products. The 15th unit shipped to Hoa Phat includes remote diagnostic capabilities, allowing Pomini Tenova engineers in Italy to monitor machine performance and troubleshoot issues without travelling to Vietnam. This connectivity proved particularly valuable during the COVID-19 pandemic when travel restrictions limited on site support. A Pomini Tenova technical manager stated that the company’s roll grinders now achieve 98% uptime across global installations, a metric that Hoa Phat’s maintenance teams have validated through operational data. The Italian manufacturer has also developed environmentally friendly grinding fluids that reduce waste disposal costs and minimise worker exposure to hazardous chemicals. These fluids recycle continuously through filtration systems, extending fluid life from weeks to months.

Vietnamese Vitiation & Velocity Vault

Vietnam’s steel industry has experienced explosive growth over the past decade, driven by rapid urbanisation, infrastructure investment, and manufacturing expansion. The country now ranks among the world’s top 15 steel producers, surpassing traditional European producers like Belgium and the Czech Republic. Hoa Phat’s Dung Quat complex alone employs over 15,000 workers, many operating sophisticated rolling mills supplied by German, Italian, and Japanese equipment manufacturers. Roll grinders play an often overlooked but crucial role in maintaining production velocity. When a rolling mill’s work roll develops surface damage from contact with hot steel or foreign materials, the entire production line may stop until a replacement roll is available. Hoa Phat’s 15 roll grinders allow the company to maintain a rotating inventory of prepared rolls, minimising downtime during roll changes. Each grinder can process multiple rolls per shift, grinding off surface defects, restoring crown profiles, and polishing to specified finishes. The newest Pomini Tenova unit features automated loading and unloading systems, reducing manual handling risks and increasing throughput. A Hoa Phat production executive commented that roll grinding capacity now exceeds the company’s current rolling needs, creating buffer capacity for future expansions. This forward looking approach characterises Hoa Phat’s broader strategy: building infrastructure ahead of demand rather than reacting to bottlenecks after they emerge.

Dung Quat’s Domain & Derivative Dynamics

The Dung Quat Economic Zone, located in Quảng Ngãi province along Vietnam’s central coast, has become the epicentre of Vietnamese heavy industry. The zone benefits from deep water ports capable of accommodating Capesize bulk carriers, direct rail connections to major cities, and proximity to iron ore sources in northern Vietnam and imported coking coal from Australia. Hoa Phat’s Dung Quat complex includes sinter plants, blast furnaces, basic oxygen furnaces, slab casters, hot strip mills, and finishing lines. The 15th Pomini Tenova roll grinder will likely serve the hot strip mill’s finishing stands, where surface quality requirements are most demanding. Finishing mill work rolls typically require grinding every 500 to 1,500 metric tons of production, depending on strip width and rolling temperature. With Dung Quat 2 adding another hot strip mill, total roll grinding demand will approximately double by 2026. Hoa Phat has also begun producing specialised steel grades for automotive exposed panels, a market segment requiring exceptional surface quality free from any roll induced defects. Pomini Tenova’s grinding technology enables the submicron tolerances necessary for such applications. A Vietnamese industry analyst noted that Hoa Phat’s vertical integration, from raw materials to finished steel, gives it cost advantages over competitors who must purchase slab or billet from third parties. The roll grinders represent a small fraction of total capital expenditure but enable the quality consistency that justifies premium pricing.

Italian Craftsmanship’s Indo-Pacific Inroads

Pomini Tenova’s 15th grinder shipment to Hoa Phat underscores Italy’s continued relevance in heavy industrial equipment manufacturing. While Asian competitors have captured market share in basic rolling mill components, Italian suppliers retain dominance in high precision machinery like roll grinders, wire rod blocks, and finishing equipment. Pomini Tenova’s grinders incorporate grinding spindles manufactured in house, each balanced to operate at speeds exceeding 2,000 revolutions per minute without vibration. The company also supplies measurement systems that use laser triangulation and inductive sensors to map roll contours with micron level accuracy. Hoa Phat selected Pomini Tenova over Japanese and German competitors after evaluating total cost of ownership, including energy consumption, consumable wheel life, and maintenance intervals. The Italian grinders demonstrated 15% lower energy use per roll and 20% longer grinding wheel life compared to the nearest competitor’s offering. A Pomini Tenova export manager stated that Southeast Asia now represents the company’s fastest growing market, with new orders from Indonesia, Thailand, and Malaysia complementing Vietnamese sales. The company has established a spare parts warehouse in Singapore to reduce delivery times for critical components. This regional presence has shortened typical parts delivery from 30 days to under 5 days for stocked items. Hoa Phat’s maintenance team has received extensive training at Pomini Tenova’s Italian headquarters, learning advanced grinding techniques and predictive maintenance protocols.

Roll Grinding’s Rarified, Recondite Realm

Roll grinding differs fundamentally from conventional cylindrical grinding because rolls operate under extreme thermal and mechanical loads in steel mills. A work roll in a hot strip mill may reach surface temperatures of 600°C during rolling, causing thermal expansion that changes roll diameter by several millimetres. The grinding process must remove surface fatigue cracks, also known as fire cracks, that propagate from the roll surface inward during repeated heating and cooling cycles. Pomini Tenova’s grinders employ specially formulated grinding wheels composed of ceramic alumina abrasives that cut efficiently without generating excessive heat, which could damage the roll’s hardened surface layer. Each grinding cycle removes between 0.1 and 0.5 millimetres of roll diameter, with deeper cuts reserved for rolls with significant fire crack networks. After grinding, rolls undergo eddy current testing to verify complete crack removal, a non destructive method that detects surface and subsurface discontinuities. Hoa Phat’s quality control team has documented that Pomini Tenova’s grinders produce rolls with fire crack removal rates exceeding 99%, meaning fewer than 1% of ground rolls require regrinding due to residual cracks. This performance reduces roll consumption by approximately 15% compared to industry averages, saving Hoa Phat millions annually in roll replacement costs. The 15th grinder includes an automated crack detection system that maps crack locations before grinding and verifies removal afterward, eliminating manual inspection steps and reducing human error.

Future Filaments & Foundry’s Flourishing Forecast

The relationship between Pomini Tenova and Hoa Phat shows no signs of slowing. Hoa Phat’s announced plans include a third Dung Quat expansion phase, potentially adding electric arc furnace based steelmaking to complement existing blast furnace capacity. This hybrid configuration would produce both carbon intensive primary steel and lower carbon recycled steel, allowing Hoa Phat to serve green conscious export markets. Each new rolling facility will require additional roll grinding capacity, likely bringing Pomini Tenova’s total supplied grinders to 20 or more by 2030. The Italian manufacturer has also proposed supplying roll shop management software that optimises grinding schedules, tracks roll life data, and predicts maintenance needs using machine learning algorithms. Hoa Phat’s leadership has expressed interest in digital transformation initiatives that reduce operational costs while improving product consistency. A Hoa Phat senior vice president stated that the company’s goal is to achieve world class overall equipment effectiveness metrics, exceeding 85% across all rolling mills. Roll grinding contributes to this goal by ensuring that rolls are always available when needed, ground to correct specifications, and free from defects that could cause unplanned downtime. Pomini Tenova’s ability to deliver 15 grinders over 18 years demonstrates both parties’ commitment to long term partnership over transactional purchasing. As Vietnam’s steel industry continues its upward trajectory, this Italian Vietnamese collaboration will likely serve as a model for other industrial equipment relationships across Southeast Asia.
