| Abstract: | 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 in creased to 89.3% from original 60% to insure the aim structure and properties of products. |
