摘要
针对中厚板生产中出现的延伸率不合的问题，采用低倍检验、金相分析、扫描电镜检验等对中厚板金相组织和缺陷形貌进行研究。结果表明：钢中偏析带中的硫化物夹杂是这一类型中厚板延伸不合的主要原因。
According to the problem of low elongation medium plate ,study on macrostructure , macrostructure and fracture pattern of steel plate and slab was performed. The effect of the slab intermediate crack low power rating and rolling compression ratio to the steel properties and the inspection results had been analyzed.
