中频炉的工作原理
Working principle of intermediate frequency furnace
中频炉主要由电源、感应圈及感应圈内用耐火材料筑成的坩埚组成。坩埚内盛有金属炉料, 相当于变压器的副绕组, 当感应圈接通交流电源时, 在感应圈内产生交变磁场, 其磁力线切割坩埚中的金属炉料, 在炉料中就产生了感应电动势, 由于炉料本身形成一闭合回路, 此副绕组的特点是仅有一匝而且是闭合的。所以在炉料中同时产生感应电流, 感应电流通过炉料时, 对炉料进行加热促使其熔化。
The intermediate frequency furnace mainly consists of a power supply, an induction coil, and a crucible made of refractory materials inside the induction coil. The crucible contains metal furnace material, which is equivalent to the secondary winding of a transformer. When the induction coil is connected to an AC power supply, an alternating magnetic field is generated inside the induction coil. The magnetic field lines cut the metal furnace material in the crucible, creating an induced electromotive force in the furnace material. Due to the closed circuit formed by the furnace material itself, this secondary winding has only one turn and is closed. So, an induced current is generated simultaneously in the furnace material, and when the induced current passes through the furnace material, it heats it to promote its melting.
中频电炉利用中频电源建立中频磁场，使铁磁材料内部产生感应涡流并发热，达到加热材料的目的。中频电炉采用 200-2500Hz中频电源进行感应加热，熔炼保温，中频电炉主要用于熔炼碳钢，合金钢，特种钢，也可用于铜，铝等有色金属的熔炼和提温.装置体积小，重量轻， 效益高，耗电少，熔化升温快，炉温易控制，生产效益高。
The intermediate frequency electric furnace uses an intermediate frequency power supply to establish an intermediate frequency magnetic field, causing induced eddy currents and heating inside the ferromagnetic material, achieving the purpose of heating the material. The medium frequency electric furnace uses a 200-2500Hz medium frequency power supply for induction heating, melting and insulation. The medium frequency electric furnace is mainly used for melting carbon steel, alloy steel, special steel, and can also be used for melting and heating non-ferrous metals such as copper and aluminum. The equipment is small in size, light in weight, high in efficiency, low in power consumption, fast in melting and heating, easy to control the furnace temperature, and high in production efficiency.
