压缩机用热轧酸洗板冲压开裂原因分析及对策

Causes and Countermeasures of Cracking during Stamping of Compressor Hot-rolled Pickling Steel

对压缩机用热轧酸洗板在用户冲压过程中出现开裂进行了分析,分析结果表明压缩机用热轧酸洗板特别是边部厚度控制及混晶等问题是压缩机用酸洗板冲压开裂的主要原因。生产实践也表明,在设计时,制定合理热轧工艺制度、减小宽度方向同板差均可有效降低冲压开裂的发生率。

Severe cracking during the customer stamping of compressor hot-rolled pickling steel , the results of which show that compressor hot-rolled pickling steel, in particular, edge thickness control and mixed crystal, etc. are the primary causes of the stamping cracking. Production practice also shows that, at design time, making reasonable hot rolling process system、reducing the width of the same plate can effectively reduce the incidence of stamping cracking.
