UP FURNACE CO., LTD. was founded in 2018, a wholly-owned subsidiary of SHENDA ELECTRIC GROUP CO.,LTD, specializes in R&D, manufacturing, installation, maintenance and transformation of electric furnace products and EPC contracting business of metallurgical engineering. It is an emerging company for various large-scale steelmaking electric arc furnaces, ladle refining furnaces and large non-standard heat treatment furnace and other products in China.
Design and manufacturing capability:
1.Steelmaking electric arc furnace: the main equipment for smelting scrap steel, currently widely used three-phase AC arc smelting, there are three kinds of power configuration of ordinary power, high power and ultra-high power, rated capacity from 1.5t to 150t.
2.Ladle refining furnace: including LF, VD, VOD, VAD, RH and other furnace types, the most commonly used is LF ladle refining furnace, rated capacity from 10t to 300t.
3.Submerged arc furnace: mainly includes ferrosilicon furnace, ferromanganese furnace, ferrochromium furnace, ferronickel furnace, calcium carbide furnace, industrial silicon furnace, etc. The power is from 6300KVA to 48000KVA.
ELECTRIC ARC FURNANCE
Steelmaking electric arc furnace is divided into normal power, high power and ultra high power according to matched power. It also can be divided into independent foundation, conjoined foundation, large pivotal bearing and four connecting link structure by roof rotating mechanism. There are left operation and right operation types for user's selection. According to the loading method, it can be divided into horizontal continuous feeding type electric arc furnace and furnace lid rotating top-opening feeding type electric arc furnace.The electric arc furnace consists of furnace body, furnace roof, tilting device, furnace lifting & rotating device, electrode lifting device, water-cooling device, hydraulic device, furnace transformer, secondary busbar, HV cabinet, LV electric and automatic control system etc, Capacity of EAF manufactured by our company is 10t-220t.

Electric arc furnace uses electricity as fuel source and utilizes the arc high temperature produced by electrode and furnace charge to heat and melt the furnace charge. It is widely using in production of normal steel, high quality carbon steel, various alloy steel, stainless, various ferroalloys. It is the key equipment in steel making factories, foundry factories, ferrous alloys making factories and etc.
Characteristic:
1, Smelting temperature is flexible to be controlled, to meet different steel grade production needs.
2, High heat efficiency, atmosphere inside furnace can be controlled.
3, Remove the phosphorus, sulfur, oxygen and other impurities and improve steel quality.
4, Easy to control the chemical composition of steel, stable and high recovery rate of alloys.
5, Equipment is simple and shorter technological process.
