Exploratory analysis of surface longitudinal cracks on wide slab |
|
|
|
Abstract This article first introduced mechanism of longitudinal cracks on wide slab how to produce, and then analyzed the processing factors which influenced longitudinal cracks on wide slab by the backward method. The article combined with the actual production, and adopted the feasible processing measure. It analyzed emphasis from the conditions of the liquid steel, optimizing components of powder, the SEN’s depth of penetration, heat transfer of mould, the cooling system and the casting speed, and better effective was got finally.
