The VIM-VIDP1000 6-ton vacuum induction furnace is a world-leading vacuum induction furnace imported from Germany’s ALD company, which can produce high-quality vacuum bars with a diameter of 80-580 mm, a length of 1,000-4,000 mm, and a weight of 0.04-6 tons.
With two crucibles of 3 tons and 6 tons, the furnace has an independent melting chamber, a top charging chamber, a side charging chamber, an ingot casting chamber, and a launder chamber. The powerful vacuum system of the furnace can achieve a limiting vacuum of 0.07P and an air leakage of 32Pa-L/s. Special alloys with extremely low O, N, and H contents can be produced. During casting, the purity of the molten steel can be guaranteed by two layers of slag screen and ceramic filter, thus ensuring the reliability of product quality from the equipment.
VAR L660 P6型6吨真空自耗炉是从德国ALD公司引进的世界领先水平的真空自耗炉，可生产直径Φ305-Φ660mm、长度1500-2700mm、重量1-6吨的优质真空自耗钢锭。
The VAR L660 P6 6-ton consumable electrode vacuum furnace is a world-leading consumable electrode vacuum furnace imported from Germany’s ALD company, which can produce high-quality vacuum consumable steel ingots with a diameter of 305-660 mm, a length of 1,500-2,700 mm, and a weight of 1-6 tons.
The furnace adopts the rotary structure of the “H” type double-station furnace body. The design of helium cooling and jet flow water jacket can minimize the segregation of steel ingot.
The electrode X-Y adjustment system can ensure the consistency of the annular space for melting;
The automatic cooling intensity control system can ensure the uniform structure of the furnace; The configuration of the high-efficiency vacuum system can achieve a melting vacuum degree of 0.08 Pa;
The overall weighing accuracy can reach 0.125% due to the high-precision and full-compensation weighing system. The entire process, including welding, arcing, melting, and filling, is computer controlled. This ensures and maintains the high quality of the molten products. Moreover, the important parameters of the melting process are recorded by the computer in real-time, and then a trend chart is automatically generated and saved for immediate observation, thus ensuring the permanent traceability of the product.
Imported from Germany's ALD company, the ESR FB 830/17 WIII 18-ton three-position protective atmosphere stripping electroslag furnace is a world-leading electroslag furnace.
It can produce high-quality electroslag ingots with a diameter of Φ360-Φ820mm, length of 1,000-4,000mm, and weight of 1-18 tons.
The furnace's coaxial conductive design can minimize energy consumption and stray magnetic field interference during smelting;
The high-precision weighing system can accurately control the melting rate; The electrode X-Y adjustment system can ensure a consistent melting gap;
The inert gas control system yields a reduction in the burnout of easily oxidized elements, while also reducing the potential for an increase in O, N, and H. The system incorporates advanced intelligent control technologies, including automated control of melting speed, automatic control of steel liquid level, and fluctuation control of slag resistance, all of which work in tandem to allow for automatic regulation of smelting to reasonable states in the presence of anomalous conditions. During the melting process, all impactful parameters are monitored and recorded in real-time by the computer and can be observed and stored instantaneously as trend charts, thereby ensuring the permanent traceability of the product.
