6300KVA-63000 KVA submerged ferroalloy furnace steelmaking furnace iron making furnace ferroalloy arc furnace

Brief introduction of Hong xin Arc Furnace Company 

Xi'an hongxin Arc Furnace company limited specilized in developping, designing, manufacturing, engineering, 

installing and technical service of ferroalloy submerged arc furnace, new type metallurgy eqiupment and gasp 

purification system. It has a registered capacity of 10 million CNY and there are more than 150 staff in the company. 

Hong xin company has its own manufacturing plant with the area convering around 10000 m 2, equipped 

well by different kinds of processing equipment, which can meet the requirements for making submerged 

arc furnace, gas purification system et. meanwhile , company has full ability of perform the turnkey project. 

Product description 

Electric arc furnace is an electric furnac for smelting ores  and metals at high temperature produced by 

electrode arc. When gas discharge forms arc, the energy is very concentrated, and the temperature of 

arc region is above 3000 C. For smelting metals,  EAF is more flexible than other steelmaking furnaces. 

It 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 smelting high quality alloy steel.
