摘要
通过对大型板类铸钢件产生变形缺陷实例进行理论分析与探讨,得出变形的主要原因是由于金属液在冷却时的内部应力作用而产生的。针对产生变形原因,采取改变浇注形式和合理设置内浇道等措施,有效地控制了大型板类铸钢件的变形量。
Through the theoretical analysis and discussion of defects case of the large plate deformation, come to conclusion that the deformation was mainly due to the internal stress when the metal liquid was in the cooling. For the reasons of the deformation,altering the measures of changing the form of pouring and setting the inner runners reasonably were taken, the deformation of the large pieces of steel plate was controlled greatly.
