Abstract
The possibility of transverse corner cracking in slab of peritectic carbon steel is greater than that of other carbon steels. The main operation and equipment reasons of transverse corner cracking are introduced. A series of measures, namely the improvement of cooling conditions of liquid steel in mold and strand in second cooling zone and reduction of stress in solidified shell implemented, over the past several years have efficiently reduced the transverse corner.
