连铸热坯热送直轧技术,是连铸—棒材轧钢生产新工艺。连铸热坯通过辊道热送,不再经过加热炉,直接传送进入轧钢生产线的粗轧机进行轧制。这项技术实现的技术难度很大。在吸收外厂的经验教训基础上,对连铸—热送—轧钢的一系列工序做了大量改进与试验,最终表明:(1)技术获得成功,证明连铸热坯热送直轧技术是可行的;(2)实现了规模生产,已稳定运行并生产了3年多;(3)每年获得经济效益5 000万以上;(4)总结出一套行之有效的生产管理、技术管理的措施。对连铸热坯热送直轧的电气自动化专业部分,在连铸控制、热坯长度切割的控制、热坯称重、收集、剔除和移钢控制、热送辊道与传送控制、热坯传送过程头部加温技术、轧钢粗轧机入口前控制、轧钢生产线主轧区域控制、电气自动化软件核心技术与硬件配置要点等方面,采取的一系列核心技术与关键技术措施,作了技术论述与介绍。 Continuous casting hot billet hot straight rolling technology, continuous casting - bar rolling a new technology. Continuous casting hot billet through the hot roller conveyor, no longer through the furnace, directly sent to the rolling mill production line rolling mill. The technology to achieve this technology is very difficult. Based on the experiences and lessons learned from the outside plant, a great deal of improvement and experiment have been made on a series of processes of continuous casting-hot-rolling-rolling. The results show that: (1) The technology has been successfully proved that the technology of continuous hot- Feasible; (2) Realization of large-scale production, stable operation and production for more than three years; (3) Annual economic gain of more than 50 million; (4) Summarizing an effective set of production management and technical management Measures. On the continuous casting hot billet hot straight rolling electrical automation professional part of the continuous casting control, cutting the length of the control of hot billet, hot billet weighing, collecting, removing and moving steel control, hot delivery roller and conveyor control, hot blank A series of core technologies and key technical measures adopted in the process of head heating in conveying process, pre-entry control of rolling mill roughing mill, main rolling area control of rolling mill production line, key technologies and hardware configuration of electrical automation software, and technical discussions Introduction.
