传感器简要介绍附后。
Attached with the sensor brief introduction
传感器工作原理
传感器采用电磁感应的原理进行信号检测，其典型结构是两同心线圈。当初级线圈通以中频激磁电流时，由于磁场作用，在钢流中产生涡流,其磁场方向与线圈产生的磁场方向相反.因为渣的电导率在高温情况下远低于钢液的电导率（约1/1000），所以在渣中产生的涡流远小于钢液中产生的涡流。浇钢过程中，开始浇注时流出的全部为钢水，到浇钢后期，钢渣混出，,使溶体电导率下降，电磁场将有所增强，此信号由次级线圈测得。
The working principal
The system uses the electromagnetic principal for detecting the slag; the typical structure is two concentric coils. When primitive coil has been conducted by mid-frequency excitement current, there will be eddy current produced in liquid steel at the opposite direction because of the magnetic field. Because the conductivity of slag is much lower than liquid steel’s (about 1/1000); the eddy current of slag will be much lower than that of liquid steel. So during casting procedure, first come out is totally liquid steel, and at the end, there will be slag sneaked in, which will cause lower conductivity, and then higher magnetic field density, that will be capture by the secondary coil.
传感器构成原理
采用耐高温材料将N1.N2两组特制线圈隔离，把线圈整体封装在一个特殊钢制成的扁型环中，并从两组线圈中运用独特的技术方法引出两对信号线，传送到二次部分。
