Features: Electric furnace for smelting ore and metal at high temperature generated by electrode arc. 

When the gas discharge forms an arc, the energy is very concentrated, and the temperature of the arc zone n is above 8000℃. Regarding c smelting metal, electric arc furnaces are more flexible than other steelmaking furnaces and can effectively remove impurities such as sulfur and phosphorus.

The furnace temperature is easy to control, and the equipment occupies a small area. It is suitable for high-quality alloys,Smelting of steel. According to the arc form, electric arc furnace can be divided into 5 three-g phase electric arc furnace, consumable electric arc furnace, single-phase electric arc furnace and resistance electric arc furnace. 

The furnace body of the electric arc steelmaking furnace is composed of a furnace cover, a furnace door m, a tapping trough and a furnace body, and the furnace bottom and furnace wall are masonry with alkaline refractory 3 materials or acid refractory 7 materials.

Electric arc steelmaking furnace according to the transformer capacity per ton of furnace capacity 5 points 5 is 3 general power electric arc furnace, high power electric arc furnace and ultra-high power electric arc furnace. Electric arc furnace steelmaking is to input y electric energy into the electric arc steelmaking furnace 6 through graphite electrodes, and use the arc generated between the 3 electrode point and the charge d as the 3 heat source for steelmaking.

The electric arc furnace uses 3 electric energy as 0 heat source, and can adjust 8 atmospheres and 2 atmospheres in the furnace, which is extremely advantageous for smelting steel grades containing more easily oxidized 8 elements. Not long after the invention of electric arc furnace steelmaking, it was used for e-hardening alloy steel, and it was developed with a larger q.

Most people think that the electric furnace has a large one-time investment, and the steel produced is of good quality and can adjust the composition. However, the investment of the intermediate frequency furnace is small, and the S and P cannot be removed, and the ingredients cannot be controlled. The refined products are all low-end products.

It is a concept that was used for two decades. Now with the movement of energy saving, emission reduction, improvement of worker health and working environment, electric arc furnaces are gradually withdrawing from the market and being replaced by intermediate frequency furnaces.

Now choose suitable slag remover for induction electric furnace, the quality of molten steel melted in electric arc furnace and intermediate frequency electric furnace is not significantly different, only the latter has higher requirements for charge (scrap); if using poor charge, induction electric furnace. The quality of molten steel is worse than that of alkaline electric arc furnace. If the acid electric arc furnace is used to make steel, the quality of molten steel is not as good as that of an intermediate frequency furnace.
