摘要
武钢2250 mm热连轧机组在生产X60管线钢等新钢种时,原有的层流冷却系统不能适应冷却要求,影响了卷取温度的控制,导致产品组织和性能不稳定。通过层流冷却系统控制模型的优化和冷却系统相关参数的调整,使卷取温度控制命中率由原来的60%提高到89.3%,保证了产品目标组织和性能。
As new steel grades such as X60 pipeline steel etc. were produced by 2250 hot rolling mill at Wuhan Steel, the original laminar flow cooling system could not meet the needs of steel cooling to effect the control of coiling temperature led to un-constant structure and properties of products. With optimization of control model for laminar flow cooling system and adjustment of relative parameters of cooling system, the percentage of hits of coiling control temperature increased to 89. 3% from original 60% to insure the aim structure and properties of products.
