1连铸坯热送热装工艺技术应用研究 1 2 赵海峰 龙正民 （1. 河北钢铁集团邯郸钢铁集团有限责任公司技术中心；2. 河北钢铁集团邯郸钢铁集团有限责任公司生产制 造部，邯郸 056015 ） 摘 要 对连铸坯热送热装工艺技术的发展、现有工艺流程、品种、质量、温度等进行了应用研究，要达到好的热 送热装效果，必须要保证热装率≥60% 以上。好的工艺线热装率应达到80%以上。温度必须在400 ℃以上。好的工 艺线应该达到 650℃以上。从运输方式看，倾向于辊道运输，另有火车、汽车及天车运输。辊道近距离运输是将来 设计的趋势。从热送热装的品种、质量看，能热送的品种较多，质量能够满足工艺要求。采用该工艺可以增加产量， 提高加热能力及质量，降低了加热炉燃气消耗和加热炉吨钢消耗，减少氧化烧损，提高成材率等，并取得了一定的 经济效益。 关键词 连铸坯 热送热装 发展 工艺流程 品种 质量 温度 Research of Hot Delivery and Hot Charging Technology of Continuous Casting Billet Zhao Haifeng1 Long Zhengmin2 (1.Technical Center；2.Production Manufacturing Department， Hebei Iron Steel Group Handan Iron Steel Group Co., Ltd. , Handan， 056015) Abstract This paper used and studied the development of hot delivery and hot charging technology，existent technology process ，variety ，quality，temperature and so on, in order to reach good effect of hot delivery and hot charging technology， hot charging rate above 60% must be assured. Hot charging rate of good technology process is to reach above 80%. The temperature must be above 400℃, good technology process is to reach above 650 ℃.From transportation way, tend to roll transportation, other having train, automobile and overhead transportation. Roll short cut transportation is the tread of in the future plan.From the variety、the quality of hot delivery and hot charging, the variety of hot delivery is more than, the quality can meet technology requirement. Using the technology can add output, raise heat up ability and quality ,lower heat up stove fuel consumption and ton steel consump
