Energy Saving Vertical And Continuous Charging Scrap Preheating Electric Arc Furnace - China

price: contact company for price

Outstanding merits of shaft electric arc furnace:

1) Scrap entered from top into shaft in batches. High temperature flue gas and scrap flowed reversely. Effect of scrap preheating is obvious. Due to the reduction of the weight of each batch of scrap steel and the reduction of scrap’s standing time on shaft finger. The possibility of bonded scrap steel is eliminated. Meanwhile, shock of scrap steel on finger is reduced.

2) Lower fingers in the furnace can lift to avoid the damage caused by the falling of scrap steel.

3) The charging basket enters closed chamber firstly before it enters into shaft. Scrap steel is added into shaft in fully sealed condition. So, when adding scrap, escape of fume and dust is avoided. It is very helpful to environmental protection.

4) Vibrating continuous feed and 50% of remaining steel capacity is adopted to ensure the condition of molten pool. Electric arc doesn’t contact with materials of steel. Electric arc is stable. Fluctuation and flicker of voltage is sharply reduced. Noise is very low.

5) Because there is no direct contact between electric arc and scrap steel, volatile substance is reduced. The amount of dust is reduced because of filtration of scrap to flue gas. It lays the foundation of dedusting system.

6) Due to reduction of volatile substance and the control of foaming slag, the iron recovery is increased 1.5- 2.0% .

7) The rotary operation of furnace lid is not to reduce subsidiary operation time. Radiation heat of rotating furnace lid is avoided.

8) High impedance technology is adopted to improve the secondary voltage and to reduce the secondary current. Consumption of effective power is reduced 6- 8% . Weight of short net system is effectively relieved.

9) Device configuration is concise and reasonable. It overcomes the shortages such as taking up large area, too much height of shaft plant. Thus, the cost of investment is lowered.

Main technical parameter:

Power consumption: <300Kwh/ t ( Above 40 tons)

Time Shorten: 20min/ furnace

Electrode Waste: 1.5- 2KG/ T

Scrap Steel Yield: 93.5- 94%

  • Business Description: Profile:

    SHOO IN (ITL) Holding Xi'an Equipment Co., Ltd is specialized in producing electric arc furnace, refining furnace, VD, VOD vacuum casting and kinds of ferro alloy submerged arc furnace and medium frequency furnace as well as spare parts and metallurgical equipment. It is an international metallurgical equipment engineering company, which is shared by Hong Kong international super large enterprise group SHOO IN (ITL) holding Xi'an equipment Co., Ltd and hold by Fujian new investment management Co., Ltd. Senior management, key technical staff, line manager, installation and debugging personnel in SHOO IN also share. The registration place is Xi'an China. With the development of more than ten years, SHOO IN has been a large comprehensive engineering company. The main business is domestic first class metallurgical equipment design, production, complete design and project general contracting. There are over 100 staff which include 50 workers and 40 people for designing and administration. We also have lots of expert of high reputation as counselor group to supply solution on innovative and high technology, management, quality controlling etc. The engineering project contracting is all over the country related with more than 100 large and medium sized enterprises in more than 10 provinces, municipalities and autonomous regions. At the same time, our company supplies steel mill in many countries and regions with equipment, technical cooperation, technical exchange and joint design. What's more, environmental protection and energy saving vertical charging scrap preheating arc furnace independently developed by our company has reached the international lowest power consumption. Power consumption of scrap steel smelting is close to 300 KWH per ton, and reduce the cost $12.3 for per ton steel. Take an example of annual output 200000 tons of steel factory, power consumption and energy saving aspects increase profits $2.5 million. The electrode adjustment system is adopted Siemens technology. The electric furnace and the vertical feeding system are developed by our company independently. And we applied for a patent. Our company applied for dozens of patents over the years. We often have technical exchanges with Japan, America, Germany and other countries. We also exchange and cooperate with China Iron & Steel Research Institute and academic institutions such as University of Science and Technology Beijing, Northeastern University, Xi'an University of Architecture and Technology, Xi'an University of Technology, etc. Thus, our company made a breakthrough in multiple key technology of metallurgical equipment. Now, we are applying for national energy conservation and scientific research funds. The concept of our company is "Establishing the industry credibility; Win the customers trust. " Our company sincerely provides first class and advanced equipment for domestic and abroad customers. We would like to make efforts in energy conservation and improving company profitability to reach the international leading level. At present, leading products and scope of business supplied by our company for customers at home and abroad are as follow: 1.15 350t three arm ladle refining furnace 2. National level key new product 15 100t three phase single arm ladle refining furnace 3. Domestic advanced 20 150t high impedance and ultrahigh power electric arc furnace 4.
