亚速钢厂X52、X60、X70连铸坯轧制生产时,利用综合分析方法来确定参数最佳值,以确保降低产品的缺陷率。连续287炉钢水用作研究材料,在此基础上创建了数据库,其中列入了生产参数,连铸坯和轧板质量评定以及化学组成的主要元素,它们的比例和氢含量。所研究钢的化学组成是(%):0.06～0.19 C; 0.74～1.70 Mn;0.13～0.22 Si;0.005～0.013 S; 0.008～0.017 P;0.01～0.03 Cu;0.03～0.08 V; 0.021～0.052 Al:0.005～0.022 Ti;0.001～0.004 Ca;
During the rolling production of X52, X60 and X70 continuous casting mills in Asia Speed Steel, a comprehensive analysis method was used to determine the optimum value of the parameters to ensure that the defect rate of the products was reduced. A continuous stream of 287 furnaces was used as research material, on the basis of which a database was created which included the production parameters, the quality of the slab and rolled sheet and the main elements of the chemical composition, their proportions and hydrogen content. The chemical composition of the studied steel is (%): 0.06-0.19 C; 0.74-1.70 Mn; 0.13-0.22 Si; 0.005-0.013 S; 0.008-0,017 P; 0.01-0.03 Cu; 0.03-0.08 V; 0.021-0.052 Al : 0.005 to 0.022 Ti; 0.001 to 0.004 Ca;
