采用具有较强通用性的板坯连铸浇铸过程静态仿真软件CCPS OFFLINE,新疆八钢一号板坯连铸机为分析对象,针对Q235B钢和08Al钢的浇铸进行了二次冷却水量的优化设计,并在实际的浇钢过程中加以了应用。生产结果表明,二冷水量优化后对应的铸坯质量(尤其是三角区裂纹)较之优化前有了明显的改善,说明通过板坯连铸凝固传热仿真计算获得的优化二冷水量具有较好的合理性和适用性,该仿真软件可广泛地应用于板坯连铸机的二冷设计之中。
The static simulation software CCPS OFFLINE and Xinjiang Bayiang No. 1 slab caster with strong generality are adopted as the analysis object. The optimized design of secondary cooling water for casting of Q235B steel and 08Al steel is carried out , And in the actual process of pouring steel has been applied. The results of the production show that the quality of the slab corresponding to the second cooling water quantity optimization (especially in the triangular zone) has been significantly improved compared with that before optimization, which shows that the optimal cooling water quantity obtained through the simulation of slab continuous casting solidification heat transfer has more advantages Good rationality and applicability, the simulation software can be widely used in the secondary cooling design of slab caster.
