摘要
为解决国内双辊连铸薄带成品率低、裂纹、易断带和轧卡等问题,对侧封技术进行研究。结果表明,侧封压力过大,引起结晶辊边与侧板磨损与电机功率消耗;侧封压力过小,又将引起漏钢。侧封板位置可以通过凝固终点位置来确定。通过采样薄带温度,建立凝固终点模型,可解决凝固终点不能测量及因干扰致其波动而不能实时修正侧封板位置的问题;通过模型参考自适应解决系统实时性和鲁棒性问题。
In order to solve the problems of low pass rate of thin strip, cracking, broken easily and mid-seizing in twin-roll continuous casting, the side seal technique was researched, The results show that the greater side pressure will cause the consumption of motor power and the friction loss between crystallization roll edge and side panel. The too small side pressure will cause the steel breakout. The location of side panel can be identified through the solidification end point. By online sampling the temperature of thin tape, establishing the model of solidification end point, the problems that the solidification end point cannot be measured directly and the side dam location cannot be accurately adjusted real-time due to interfering factors can be solved. The problem of poor real-time performance and robustness can be solved by MRAS.
