摘要
通过道次冻结功能的应用,实现了道次数的合理调控,解决了薄规格中厚板在轧制过程中温降大、增加道次、终轧温度低、板形差的工艺难点。应用此功能,莱钢4 300mm宽厚板线成功实现了在组板长度达到38m的情况下,6mm×3 000mm、8mm×4 150mm等极限规格的稳定轧制。
Through the application of the functions of frozen pass,to a reasonable pass number was achieved to solve the thin gauge plate in the rolling finishing temperature low during the process difficult.With application of this feature,4 300 mm heavy plate line successfully achieved the stability of rolling,of 6 mm × 3 000 mm,8 mm × 4 150 mm and other specifications limit,in board length of 38 m group case.
