特冶设备及特点

Special Melting Equipments and Features

Vacuum Induction Melting Furnace of type VIM-VIDP1000 is capable to produce vacuum bars in the range of diameter Φ80-Φ580mm, length 1000-4000mm, and weight 0.04-6 tons. This type of VIM Furnace has two crucibles with the capacity of 3 tons and 6 tons, separated melting chamber, top loading chamber, side loading chamber, ingot casting chamber and chute room. This Furnace equipped powerful vacuum system with maximum vacuum degree of 0.07 Pa, Leakage bearing of 32Pa·L/s, is capable to achieve extremely low con-tent of elements O, N, and H. It has two layer of slag holder and ceramic filter to ensure the purity of the molten steel, and the reliability of product quality in the equipment point of view.



Vacuum Arc Remelting furnace of type VAR L660 P6 is capable to produce VAR ingots in the range of diameter Φ303-Φ660mm, length 1500-2700mm, and weight 1-6 tons. This furnace is type H of rotary type furnace bady with dual working station. The design of Helium Cooling and Rapid layer water jacket sys-tem reduce the segregation in maximum limit. X-Y electrode adjust system is ef-fected in ensuring the consistent of melting environment. Cooling intensity au-tomatic control system makes the product has the homogeneous structure. Ef-fective vacuum system achieve the maximum vacuum degree of 0.08Pa. High precision weighting system makes the weighting accuracy achieving 0.125%. The whole processing computer control including welding, arcing, melting and filling ensure the products in a very high quality. The parameters of the smelting process were recorded and generated by computer immediately, which can be observed and stored automatically, keep the product permanent traceability.

6-ton Vacuum Arc Remelting

18-ton Electroslag Remelting

Electroslag Remelting Furnace of type FB 830/17 WIII is capable to pro-duce ingots in the range of diameter Φ360-Φ820mm, length 1000-4000mm, and weight 1-18 tons. The design of coaxial conductive reduces the consump-tion of electricity and the interference of stray magnetic field. High precision weighting system controls the melting accurately. X-Y electrode adjust system is effected in ensuring the consistent of melting environment. Inactive gas control system is effected in decreasing the burning loss of active elements and pre-venting the increase of element O, N and H. Melting speed, melting liquid height level and slag resistance fluctuations automatic control system ensure the melt-ing in a preferred state in case of any abnormalities happend in the melting process. All important parameters are recorded by computer and generate trend chart which is available to check and saved automatically, ensuring the permanent traceability of products.
