A study of breakout of a continuously cast steel slab due to surface cracks
Original language description
The solidification and cooling of a continuously cast slab and the simultaneous heating of the mold is a very complicated problem of three-dimensional transient heat and mass transfer. The solving of such a problem is impossible without numerical modelsof the temperature field. Experimental research and measurements must be carried out simultaneously with numerical computation. An important area of the caster is the so-called secondary cooling zone, which is subdivided into thirteen sections. In the secondary cooling zone, where the slab begins to straighten, a breakout of the steel can occur at the points of increased local chemical and temperature heterogeneity of the steel, due to increased tension resulting from the bending of the slab, and also due to high local concentration of non-metallic, slag inclusions. The changes in the chemical composition of the steel, during the actual continuous casting, are especially dangerous. In the case of two immediate consequent melts this coul
