HX Electric Arc Furnace Steelmaking

發(fā)表時間：2017-12-01 14:35:55 瀏覽量：4619

Electric Arc Furnace is a steelmaking equipment utilizing the thermal energy of arc generated

Between electrodes and scrap or metallic material, and is widely used for production of plain steel, top quality carbon steel, alloy steel, stainless steel in steelmaking works and steel-casting plant。

Technical features ：
The following advanced technologies are to be applied to our KAIYUAN electric arc furnaces such as tubular water cooled wall panel, water cooled roof panel, eccentric bottom tapping,
Copper-clad conductive electrode arm, intellectual electrode regulator of energy saving, PLC industrial screen monitoring system, etc。
◆ Flexible control of temperature。
In the steelmaking process the temperature of liquid steel can be flexibly controlled by means of adjustment of current and voltage, so to meet the requirements for production of various grades of steel。
◆ Higher thermal efficiency
◆ Atmospheric pressure inside furnace is controllable
◆ More inclusions, such as phosphor, sulfur, oxygen and other hazard elements can be removed from liquid steel so as to improve the steel quality，stable and higher yields of alloy elements，the chemical composition of liquid steel can be precisely trimmed，much grades of steel can be produced。
◆ Simple structure of furnace, compact process route

Latest technologies utilized ：

Optimum selection for parameters of furnace
Tubular WCP and WCR
Eccentric bottom tapping（EBT）
Copper-clad conductive electrode arm
Large section flexible water cooled cable
Optimization configuration of high current conductor system）
Hydraulic system with proportional valves block
