摘　　要：简要介绍了国内挤压用大规格铝合金铸棒感应加热技术的现状及存在的问题,根据能量守恒定律、热量计算公式等相关理论并结合生产实践,提出了新的多重防过烧、防开裂加热控制系统。通过铸棒长度测量控制、能量输入控制、测温监控热电偶对比控制等多重控制技术,解决了加热过程中因测温不准导致的铸棒过烧问题,同时也避免了因加热速度不当导致的铸棒开裂问题。The current situation and existing problems of induction heating for large size aluminum alloy billet in domestic are introduced.A new heating control system of anti-overburning and anti-cracking is proposed according to the law of conservation of energy,heat calculation formula and other related theories combined with production practice.The over-burning of the billet caused by inaccurate temperature measurement and the cracking caused by improper heating speed in the heating process can be avoided,through the billet length control,energy input control and temperature monitoring thermocouple contrast control technologies.
