Analysis of the Causes of Micro Cracks at the Edges of Steel Plates and Control Measures
In order to solve the problem of microcracks on the surface of steel plate edge,the causes of microcracks on the surface of steel plate edge were found out by field tracking and alloy phase analysis,and three aspects were improved through the vibration of mould,the control of nitride,and the optimization of cooling system.After the measures were implemented,the surface quality of the steel plate was greatly improved.
