中頻電爐通過(guò)磁場(chǎng)將能量傳遞給被加熱金屬，甚至可以進(jìn)行真空冶煉，其***率高收得率的效益優(yōu)勢(shì)是十分明顯的。大容量采用感應(yīng)電爐進(jìn)行熔化，再配以精煉爐進(jìn)行調(diào)質(zhì)，生產(chǎn)合格的鋼水，經(jīng)過(guò)連鑄(生產(chǎn)鋼坯)或模鑄(生產(chǎn)鑄件)形成粗產(chǎn)品，供軋制或精加工。

        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.

　　中頻電爐用于冶煉具有以下四大優(yōu)勢(shì)：

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

　　1、冶煉收得率。電爐是以交流磁場(chǎng)在原料內(nèi)引起感應(yīng)渦流而使原料發(fā)熱熔化，保證了資源不被浪費(fèi)，也使企業(yè)損失了可觀的經(jīng)濟(jì)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、能耗指標(biāo)。工作電壓可以高達(dá)4000V以上，從電能傳輸理論很容易理解，高壓小電流工作模式就是節(jié)能的關(guān)鍵，同容量中頻電爐比電弧爐低50度/噸鋼。

      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、電網(wǎng)污染，閃變嚴(yán)重。感應(yīng)爐為連續(xù)穩(wěn)定負(fù)載，感應(yīng)爐配備爐外精練設(shè)備后，產(chǎn)品質(zhì)量是穩(wěn)定可靠的。基于收得率的區(qū)別，在冶煉含有貴重金屬的特鋼(如不銹鋼)時(shí)，5%原料收益是中頻電爐帶來(lái)的可觀經(jīng)濟(jì)效益。而對(duì)于規(guī)模生產(chǎn)的普鋼企業(yè)，能耗指標(biāo)帶來(lái)的經(jīng)濟(jì)效益也是不可小視的。

      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、環(huán)保性。中頻爐引發(fā)強(qiáng)烈的燃燒、氧化和氣化，產(chǎn)生的煙氣量極大，通常達(dá)到3000-5000m3/噸，而感應(yīng)爐一般只有1000m3/噸，為電弧爐的1/3以下，并且煙氣中粉塵濃度也大大降低。因此環(huán)保處理成本低，容易達(dá)到環(huán)保排放的標(biāo)準(zhǔn)。

     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.
