瑞典开发了用电磁原理测量液位和检测渣的技术EMLI(电磁液位指示)、检测液芯和测量铸坯温度分布技术EMMA(电磁金属音响装置),可应用于连铸生产。1.渣的检测。利用渣导电率比钢导电率低极多的原理,用电磁法检测钢流中是否夹渣。在钢包滑动水口和钢包底部之间的注流四周装置传感器。如钢水中有渣存在,一直保持恒定的接收器信号便相应增强,发出报警信号并关闭滑动水口。
Sweden has developed EMLI (Electromagnetic Level Indicator), Electrodeposition Liquid Level Measurement (EMML), and Temperature Measurement Technology EMMA (Electromagnetic Metal Sound System) for the measurement of liquid level and slag detection using electromagnetic principle, which can be applied to continuous casting. 1 slag detection. Use of slag conductivity is much lower than the conductivity of steel principle, using electromagnetic method to detect whether the slag in the steel slag. Flow around the ladle slide between the ladle and ladle bottom device sensor. If slag exists in the molten steel, the receiver signal that has been kept constant will be correspondingly enhanced, an alarm signal will be generated and the sliding gate will be closed.
