为了减少板坯连铸机的粘结漏钢事故,研究了粘结漏钢过程的热电偶温度变化规律,建立了漏钢预报系统及粘结提醒模型、粘结报警模型和漏钢报警等相关模型。该系统在国内某钢厂应用未发生漏钢事故,将单流每月粘结报警次数降低到10次以内,报警率低于5%,报警准确率在80%左右。实践表明,该系统具有报警次数少及准确率高的特点。 In order to reduce the sticking breakout accident of slab caster, the variation law of the thermocouple temperature during the sticking breakout process was studied, and the breakout forecasting system, the sticking reminder model, the sticking alarm model and the breakout alarm were established model. The system in a domestic steel mill application did not happen to break the accident, the single stream monthly bond alarm frequency reduced to 10 times, the alarm rate of less than 5%, the alarm accuracy of about 80%. Practice shows that the system has the characteristics of less number of alarms and high accuracy.
