摘要
介绍了新钢第一炼钢厂连铸坯向中厚板厂热送热装的工艺实践,分析研究了含铌钢表面裂纹控制技术、头尾坯控制技术以及铸坯入炉温度对微合金钢表面质量的影响等。生产实践表明,铸坯热送热装攻关后,改善了铸坯质量,减轻了工人劳动强度,提高了金属收得率,大幅度降低了煤气能耗,节约了生产成本,缩短了产品的生产周期,实现了炼钢厂和中厚板厂的生产管理一体化。
This article introduces the practice of hot transmission and hot charging process of the continuous casting billet. The crack control technology of the containing niobium steel,head and tail billet control technology,and the effect of slab charging temperature on the micro alloy steel surface quality are analyzed and studied. Production practice shows that the slab quality is improved,the workers labor intensity is reduced,the metal yield is developed,the gas consumption is greatly reduced,the cost of production is saved,the production cycle is shortened,the integration of production management in the steel mill and plate plant is realized after the study.
