日本托比工业公司和住友重工公司共同开发可使连铸工序稳定的新型拉漏预报系统.它是采用金融机构等实际应用的神经网络和统计手法,识别埋入结晶器铜板中热电偶的温度变化以预测拉漏的系统.托比工业公司丰桥厂2号连铸机上使用该系统,可完全防止在拉漏中占多数的“拘束性拉漏”的发生.这对提高生产率和降低成本起很大作用,现正在申请专利.拉漏系在连铸设备中钢水没有凝固而流出的事故.根据其形态,有拘束性、裂纹性和启动失败等几种.“拘束性拉漏”的产生率占绝大多数,它是由于某种原因使凝固壳破裂,而附在结晶器壁上,断裂部分达到结晶器下端时而导致钢水喷出时产生的.在连铸工序不可避免的拉漏故障,会引起设备损坏和长时间停机,因此防止拉漏是实现连铸工序稳定的重要课题.传统的拉漏预报系统,是通过埋在结晶器铜板中热电偶的温度变化与由拉漏产
Japan Toby Industries Co., Ltd. and Sumitomo Heavy Industries Co., Ltd. jointly developed a new type of leakage prediction system that can stabilize the continuous casting process using neural networks and statistical methods such as financial institutions to identify the temperature of the thermocouple embedded in the mold copper plate Changes in order to predict the system of leakage .Toby’s industrial company Toyohashi Plant on the 2nd continuous casting machine to use this system can completely prevent the leakage in the majority of the “binding leakage.” This is to improve productivity and reduce costs Play a significant role, is applying for a patent.Slip drain system in the continuous casting equipment in the molten steel does not solidification and outflow of the accident.According to its shape, there are binding, crack and start failure, etc. “Binding leakage” Of the production rate accounted for the vast majority, it is due to some reasons that the solidified shell rupture, and attached to the mold wall, the broken part of the mold to reach the lower end of the time caused when the molten steel is emitted in the casting process inevitable pull Leakage failure will cause equipment damage and prolonged downtime, so to prevent leakage is to achieve a stable casting process an important issue.Traditional leakage prediction system, is buried in the mold copper thermocouple temperature Change with the Laguan production
