Casting defects and hot rolling process improved casting method and casting apparatus

摘要

The present invention relates to a casting mold capable of controlling the thickness of a cast steel during casting of steel or nonferrous metal and a casting method using such a casting mold. More particularly, The present invention relates to a casting method and a casting apparatus capable of reducing grain size after heat treatment and capable of shortening the rolling time during hot rolling in a subsequent process in accordance with the thickness of the cast steel. The present invention provides a casting method and a casting apparatus capable of shortening the casting crack heat treatment time of the post-process by the thickness reducing effect of the cast steel, homogenizing the material of the center material, and shortening the hot rolling process.
