To achieve slag-free tapping of electric furnaces, traditional tapping methods need to be changed. The rapid progress of electric furnace technology is not only reflected in the number of electric furnaces, but also the furnace type and tapping mechanism and control methods are constantly changing and updated, making the electric furnace slag-free tapping technology more perfect and diversified.

Electric arc furnace is an electric furnace that uses the electric heating of electric arc to smelt metal. In the electric arc furnace, there are one or more electric arcs. By the action of arc discharge, the electric energy is transformed into heat energy to supply the heat required to heat the smelting materials.

EBT electric furnace realizes the opening and closing of the water outlet through the opening and closing mechanism of the steel outlet, while blocking the steel outlet and automatic pouring are realized through the filler. If the molten steel can’t flow out automatically, the steel can be tapped by gently striking the steel drill or burning oxygen. When burning oxygen, use a special oxygen blowing elbow to blow oxygen at the steel outlet. Generally, it takes only a few seconds to burn the sintered filler at the steel outlet to make the molten steel flow out.

The furnace top, also known as the furnace cover, is in a circular arch shape and can be moved. The outer ring is a water-jacketed steel structure. During the smelting process, the furnace roof (especially the central part of the furnace roof, around the electrode hole and the dust removal hole) is at high temperature for a long time. The state of the furnace is also affected by sudden changes in temperature. The chemical corrosion of furnace gas and slagging powder, the radiation of electrode arc and the erosion of smoke and dust, the dust on the furnace roof also produces pressure and hinders heat dissipation. The furnace roof is also subject to mechanical The function of vibration, the working conditions are very bad, it is the weak link of the whole furnace lining.

Compared with traditional AC electric arc furnaces, there are those advantages. Do you know what electric arc furnaces are? In fact, electric arc furnaces are tools used to make steel. There are many types of electric arc furnaces. Different types of electric arc furnaces use different steelmaking methods. The DC electric arc furnace is derived from the DC electric arc furnace, so what are the advantages of the DC electric arc furnace? Today I will introduce you to the advantages of the DC electric arc furnace.
