中频电炉通过磁场将能量传递给被加热金属，甚至可以进行真空冶炼，其***率高收得率的效益优势是十分明显的。大容量采用感应电炉进行熔化，再配以精炼炉进行调质，生产合格的钢水，经过连铸(生产钢坯)或模铸(生产铸件)形成粗产品，供轧制或精加工。

        The medium frequency electric furnace transmits energy to the heated metal through the magnetic field, and can even carry out vacuum smelting, and the benefit advantage of high efficiency and high yield is very obvious. The large capacity is melted by an induction furnace, and then tempered with a refining furnace to produce qualified molten steel, which is subjected to continuous casting (production of billets) or die casting (production of castings) to form a crude product for rolling or finishing.

　　中频电炉用于冶炼具有以下四大优势：

       The medium frequency electric furnace is used for smelting and has the following four advantages:

　　1、冶炼收得率。电炉是以交流磁场在原料内引起感应涡流而使原料发热熔化，保证了资源不被浪费，也使企业损失了可观的经济效益。

      1. Smelting yield. The electric furnace uses the alternating magnetic field to induce eddy currents in the raw materials to melt and melt the raw materials, ensuring that resources are not wasted, and the enterprise loses considerable economic benefits.

　　2、能耗指标。工作电压可以高达4000V以上，从电能传输理论很容易理解，高压小电流工作模式就是节能的关键，同容量中频电炉比电弧炉低50度/吨钢。

      2. Energy consumption indicators. The working voltage can be as high as 4000V or more. It is easy to understand from the theory of power transmission. The high-voltage and low-current working mode is the key to energy saving. The same-capacity medium-frequency electric furnace is 50 degrees/ton lower than the electric arc furnace.

　　3、电网污染，闪变严重。感应炉为连续稳定负载，感应炉配备炉外精练设备后，产品质量是稳定可靠的。基于收得率的区别，在冶炼含有贵重金属的特钢(如不锈钢)时，5%原料收益是中频电炉带来的可观经济效益。而对于规模生产的普钢企业，能耗指标带来的经济效益也是不可小视的。

      3. The grid is polluted and the flicker is serious. The induction furnace is a continuous stable load, and the induction furnace is equipped with refining equipment outside the furnace, and the product quality is stable and reliable. Based on the difference in yield, when smelting special steel (such as stainless steel) containing precious metals, 5% raw material yield is a considerable economic benefit brought by the intermediate frequency electric furnace. For the general-purpose production of ordinary steel enterprises, the economic benefits brought by energy consumption indicators are also indispensable.

　　4、环保性。中频炉引发强烈的燃烧、氧化和气化，产生的烟气量极大，通常达到3000-5000m3/吨，而感应炉一般只有1000m3/吨，为电弧炉的1/3以下，并且烟气中粉尘浓度也大大降低。因此环保处理成本低，容易达到环保排放的标准。

     4. Environmental protection. The medium frequency furnace induces intense combustion, oxidation and gasification, and the amount of smoke generated is extremely large, usually reaching 3000-5000 m3/ton, while the induction furnace is generally only 1000 m3/ton, which is less than 1/3 of the electric arc furnace, and the dust in the flue gas The concentration is also greatly reduced. Therefore, the environmental protection treatment cost is low, and it is easy to meet the environmental emission standards.
