Optimization of Secondary Cooling on Rectangular Bloom Based on Subproblem Approximation Method


Article Preview

For understanding the surface and internal defects of Q195 steel of 150mm×220mm rectangular bloom, a solidification heat transfer mathematics model based on temperature measuring is established. Meanwhile, the secondary cooling water is optimized according to the metallurgical criteria by means of subproblem approximation method. The results showed that: after the optimizing result is applied in actual production, the water consumption is reduced 8.2~11.5%, the quality of bloom improved obviously, and the defects such as central pipe, center porosity and internal cracks are reduced respectively.
