3. Advantages of Electric Arc Furnace Buy

3.1 Low Power Consumption

The reasonable large current system layout makes the current impedance smaller. The high current system of the electric arc furnace uses pure copper as the conductive medium, and the resistance of the whole circuit is small. Taking full account of the skin effect when the current passes through the conductor, the cross arm adopts a box-type copper steel composite plate structure, which can effectively reduce the generation of resistance and heat side.

3.2 Safety & Stability of Electric Arc Furnace Buy

The whole set of the hydraulic drive is equipped with an accumulator, which can stabilize the pressure of the hydraulic system and make the operation of the equipment more stable. At the same time, in sudden accidents such as power failure, the unfinished action of the equipment can be continued, which improves the safety of smelting.

3.3 Low Electrode Consumes

Our patented technology "electrode breaking prevention system" can effectively reduce the probability of electrode breaking in the smelting process. In particular, avoiding electrode breakage during scrap melting is equivalent to saving a whole furnace of molten steel and reducing economic losses.

3.4 Simple and Convenient Operation

The electrical automation control adopts the man-machine interface, which simulates the real furnace form, and the operation is convenient. Batching, feeding, smelting and tapping can all be operated on the computer.

3.5 High Arcing Efficiency

Our patented technology "a new type of electrode regulation system" the electrode lifting control of electric arc furnace breaks the previous single signal return control technology, and adopts multi signal acquisition and PLC signal comparison technology to improve the electrode arcing speed and avoid the arc furnace from affecting the upper power grid system for a long time during the arcing process.

3.6 Diversification of Dust Removal System

We are equipped with a variety of dust removal systems, which can be equipped with different forms of dust removal equipment according to the environmental protection requirements of different countries.
