LK-EM Electromagnetic Molten Steel Level Control System |
Main Features：
●The sensor is embedded in the mold, which does not affect the replacement of the nozzle and facilitates maintenance.
●The sensor has excellent resistance to temperature drift, strong anti-interference capability, and a long service life.
●Based on the principle of electromagnetic induction, it is non-radioactive and harmless to the human body.
●Heavy-duty steel shell structure, with no damage to the sensor caused by general molten steel overflow.
●The stopper rod control system adopts a direct-drive actuator, featuring fast response.
●Electric cylinder with card slot-type quick installation, small size, light weight and good acceleration performance
●The system adopts closed-loop control, and the servo system features stable and reliable performance.
