Electric arc furnace is using electricity as fuel source, and utilizes the arc high temperature produced by electrode and furnace charge to heat and melts 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: Smelting temperature is flexible to be controlled, production needs. High heat efficiency, atmosphere inside furnace can be controlled. Can remove the phosphorus, sulfur, oxygen and other impurities and improve steel quality. Easy to control the chemical composition of steel, stable and high recovery rate of alloys. Equipment is simple and shorter technological process. Adoption of new technology: Optimization design Tubular water cooled furnace wall and furnace lid Eccentric bottom tapping (ebt) Copper-steel combined electrode arm Cluster type large sectional area water cooled cables Optimize large current system structure (energy-saving type) Proportional valves hydraulic system Basic level (plc) + procedure level ( industrial control computer) control system Frequency control technique Network technique Standard export packaging
Argon oxygen furnace is a kind of refining furnace, which is characterized by side-blowing oxygen through the bottom tuyere with an immersion way. When the tuyere center is blown in with oxygen, argon and mixed gas of nitrogen, the proportion of argen and oxygen should be adjusted, then, it can achieve the purpose of decarburizing and retaining of chrome. Argon and nitrogen are used as cooling gas for tuyere ring to extend the life of tuyere. It can get the best operation by controlling the flow of the tuyere ring. And the flow of the tuyere center and tuyere ring can be controlled in master-control room. The burning loss of tuyere, refractories and chrome is influenced greatly by the temperature of molten steel. So we can offer a special online temperature measuring system to buyers. We adopt secondary combustion of top lance technology. It can increase the volume of cold material put into the vod and shorten the duration of smelting, and guarantee the continuous casting for multiple furnaces at last. We also use the charging system with a weigh on its multiple bunkers, which can be directly connected with control system of computer. Then the smelting cycle will be shortened and labor intensity will be reduced. This equipment has a control system of intellectualized smelting process, which can decrease the consumption of all kinds of raw materials and gas during the smelting, and guarantee a stable quality of products. New security design for smelting It is aiming at the plugging of lance and the back-flow of molten steel which caused by electricity interruption during smelting process. Aod series refining furnaces have a function to keep pressure of tuyere and contain uninterruptable power output to stop the above accidents, consequently improve the safety of smelting process.

This Cast Iron slag is a by-product derived from the production of thermal insulating products. The byproduct is a ferrous slag which can be utilised in an electric arc furnace to produce crude steel. Physical Description On visual inspection, it appears to be made up of irregular shapes. Dimension: 500mm -800mm Chemical Composition Its chemical composition is homogeneous and stable with Fe contents in the range of 90 +/- 5% and P contents < 0.6% S around 0.15% and C% around 3.5%. Packing: Loose in container Loading: in 20 Container For further information, please feel free to contact us.
We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
