中频电炉采取的是采取三相桥式电路，先将交流电改变为恒定的直流电在变动为800-1000hz的交变职责电流。中频感应电炉选取电池感应加热在节制方面是很便利的，如许为中频感应电炉冷却赠与了很好的操作前提。它采取交流转直流在转交流的加热模式，有很高的效益运行起来也是比拟牢靠的。如许的意义就显示出来一个问题。
The medium frequency electric furnace adopts a three-phase bridge circuit, which first changes the alternating current to a constant direct current and then changes it to an alternating duty current of 800-1000Hz. The selection of battery induction heating for the medium frequency induction furnace is very convenient in terms of control, providing a good operational prerequisite for the cooling of the medium frequency induction furnace. It adopts a heating mode of alternating current to direct current and alternating current, which has high efficiency and is relatively reliable to operate. The significance of this indicates a problem.
中频电炉具有感应加热装置的浇往家庄电动伸缩门 保定桌椅 保定水处理装置 河北机械加工 保定养老院 保定防水护应用迅速扩大随着各种迅捷益的铸造生产线的出现，浇注工序机械化和自动化的要求更为迫切.准确的浇注温度是保证获得高质量铸件的重要条件，能贮存一定量金属液的浇注护有利于组织生产。因此，各国近20年来相继开发出来的气压式、塞杆式、气压一塞杆式以及电磁泵式保温浇注护，迅速改变了铸造浇注工序的落后面貌，提高了铸件质量，减少了废品，取得了良好的经济效果.
The application of intermediate frequency electric furnaces with induction heating devices for pouring protection is rapidly expanding. With the emergence of various high-efficiency casting production lines, the requirements for mechanization and automation of the pouring process are becoming more urgent. Accurate pouring temperature is an important condition to ensure the acquisition of high-quality castings, and pouring protection that can store a certain amount of molten metal is beneficial for organizing production. Therefore, in the past 20 years, various countries have successively developed air pressure, plug rod, air pressure one plug rod, and electromagnetic pump insulation casting protectors, which have quickly changed the outdated appearance of the casting and pouring process, improved the quality of castings, reduced waste, and achieved good economic results
由于中频电炉功率密度高，无相平衡装置，土建费用小。因此，在国外相同生产率的中频感应电护的初次投资费用较工频感应电炉低10%一15%。从冶金学角度看，在中a感应电护内熔化的金属只存在“一次过热”现象
Due to the high power density of the intermediate frequency electric furnace and the lack of phase balance devices, the civil engineering cost is low. Therefore, the initial investment cost of intermediate frequency induction furnaces with the same productivity abroad is 10% to 15% lower than that of industrial frequency induction furnaces. From the perspective of Metallurgy, the molten metal in the induction protection of medium a only has the phenomenon of "once overheating"
