中频电炉采用200-2500Hz中频电源进行感应加热,熔炼保温,主要用于熔炼碳钢,合金钢,特种钢,也可用于铜,铝等有色金属的熔炼和提温.设备体积小,重量轻,效率高,耗电少,熔化升温快,炉温易控制,生产效率高. Intermediate frequency electric furnace using 200-2500 hz medium frequency induction heating power supply, heat insulation, it is mainly used for smelting carbon steel, alloy steel, special steel, also can be used for copper, aluminum and other non-ferrous metal smelting and the temperature. Equipment is small in size, light weight, high efficiency, less consumption, melting heat up quickly, easy to control furnace temperature, high production efficiency. 　　使用电源方式不同于工频电炉，是将380V的工频交流电源输入中频电源柜（中频电源柜内具有过压保护、过流保护、如有过压、过流现象会自动停机报警），在中频电源柜内将工频交流电源整流为单相直流电，再通过逆变成为单相交流中频电压、电流（单相交流中频电压、电流是安全的），将单相交流中频电压、电流输入加热器产生感应电对锅炉内的水进行感应加热。因此本锅炉的加热过程中水电分离，安全可靠的。本锅炉还装有以下保护装置。 Use power supply mode is different from the power frequency electric furnace, is the 380 v power frequency ac power input of intermediate frequency power supply cabinet (intermediate frequency power supply is contained in the over-voltage protection, over-current protection, such as over voltage, over current phenomenon will automatically stop alarm), in the medium frequency power supply will be contained in the power frequency ac power rectifier for single phase dc, again through the inverter single-phase ac frequency voltage, electric current (single-phase ac frequency voltage and current are safe), the single-phase ac frequency voltage and current input induction heater produced for induction heating of the water in the boiler. This boiler heating process cwe separation, safe and reliable. This boiler is equipped with the following protection device. 　　1、装有温控仪，水控仪，可以自动温调，自动补水，可根据用户需要设定供水温度，回水温度自动调节。供水温度超过设定温度时，自动停机，回水温度低于设定温度时，自动开机。 1, with a temperature controller, water control device, can automatic temperature adjustment, automatic filling water, can according to user needs to set the water supply temperature, backwater temperature automatic adjustment. When water temperature more than set temperature, automatic stop, return water temperature below the set temperature, automatic startup. 　　2、装有液晶数字显示，能准确直观地显示供水温度，回水温度；炉内水位高低，可在水位计上显示，操作人员可以很清楚地掌握锅炉运行情况。 2, equipped with LCD digital display, can intuitively show water temperature, water temperature; Water level in the furnace, can be displayed on the water level gauge, operators can clearly grasp the boiler operation. 　　3、水控和传感温调报警均可转入自动保护系统，故障时，相应指示灯闪亮，且自动停机。 3, water control and sensing temperature alarm can turn into automatic protection system, failure, the corresponding light is bright, and the automatic stop.
