How to prevent corner cracks in steel castings

摘要

The present invention relates to a method for preventing corner cracks in a continuous cast steel cast steel, the object of which is to provide a method for preventing corner cracks which is a kind of surface cracks generated perpendicular to the casting direction at the edge of the hot-rolled slab.;In order to achieve the above object, the present invention controls the operating factors such that the temperature deviation measured from a plurality of thermocouples installed at appropriate positions of the mold during continuous casting of steel by injecting molten steel into the mold from the tundish. The technical gist of the method for preventing a corner crack of a continuous cast steel cast steel including a.
