Synopsis : No.3 tandem cold mill (TCM) in Chiba Works is a multi-purpose mill, whose production is ranging from the ordinary cold-rolled steel sheet to high carbon and stainless steel sheets. With the aim of improving the product quality, yield, cost, and productivity of this line, the fully continuous mill was put into operation in July 1988. To cope with high-grade quality requirements, additional improvement, mainly the installation of a final stand, was realized in July 1990. To achieve fully continuous operation, the laser welder was developed for use in the continuous rolling of a high carbon and stainless steel sheet. The shape control system using the mill with high shape control characteristics and the strip-surface quality improvement technique based on the coolant filtration system were also established to meet the quality requirements of high-grade products. |
