就结构用热轧厚钢板和钢带国家标准修订中几个主要问题及理由———牌号及化学成分、力学和工艺性能、表面质量 ,与大家进行探讨。国家标准修订后 ,与国际标准接轨 ,放开化学成分下限和力学性能的上限 ,有利于企业充分发挥成分和工艺的调控功能 ,解决长期以来因成分和性能限制太死 ,造成的成分与性能要求的矛盾。
On the structure of hot-rolled thick steel plate and strip revision of several major national issues and the reasons --- brand and chemical composition, mechanical and technological properties, surface quality, to discuss with you. National standards revised, in line with international standards, to open the lower limit of chemical composition and mechanical properties of the ceiling, will help companies give full play to the ingredients and process control functions, to solve the composition and performance limits for a long time too dead, resulting in the composition and performance requirements Contradictions.
