Control Measures to Reduce Slab Triangle Crack Ratio in Iron and Steel Company

Aimed at the cracks of continuous casting slab in the triangle area in early production of an Iron and Steel Co.,the formation mechanism of the cracks of continuous casting slab in the triangle area was studied,the effects of secondary cooling,chemical composition of the steel grade,casting machine condition,the process operation and other factors on the crack formation were analyzed,the measures to prevent the crack in triangular area from generation were put forward.In actual production,the ideas and methods how to quickly analyze and determine the cause of the crack,and to use symptomatic measures were introduced.
