Roll shop for hot rolling mill in Vietnam

WaldrichSiegen delivers roll shop for the largest greenfield project of the steel industry worldwide

FORMOSA HA TINH STEEL CORPORATION (FHS) currently realizes the largest greenfield project in the steel industry worldwide in the Vietnamese province Ha Tinh. There, the subsidiary of the FORMOSA PLASTICS GROUP (FPG) will produce five million tons of steel each year by the middle of 2015. An increase of production capacity to ten million and then 22 million tons of steel per annum is scheduled.

FPG awarded the order for a fully-automated roll shop for the new steel mill to WaldrichSiegen – a further milestone in the trusting and reliable partnership of both companies.

FORMOSA HA TINH STEEL CORPORATION will grind rolls for a new hot rolling mill in the shop. It is equipped with five roll grinders, two loaders, roll cooling and further roll shop equipment.

Following a trend in the steel industry, all work rolls are placed in the grinding machine with the help of a loader. In order to minimize auxiliary times, the work rolls are ground in chocks. The loader is equipped with a special system for turning the chocks. Thus, the collision of chocks and roll grinders is prevented. This integrated system dispenses with the separate turning of the chocks on the grinding machine. In order to eliminate mistakes and operating errors, the rolls are identified with RFID technology and all steps of the operation are documented, controlled and optimized by WaldrichSiegens' own Roll Shop Management System (RSMS). The result: Significant time savings when transporting rolls with a safe process flow.

In addition to the long-term partnership between companies, FPG had other crucial reasons to opt for WaldrichSiegen: All components are designed and produced by one source and WaldrichSiegen roll grinders are well known for reliability and their easy handling.
