Electroslag remelting process introduction - Jiangsu lotus source Machinery Manufacturing Co., Ltd.

    The main purpose of electroslag remelting is the purification of metal and denser ingot. The electroslag remelting steel, high purity, low sulfur and non metallic inclusions, ingot surface smooth, uniform chemical composition and microstructure. The mechanical properties of cast steel can reach or exceed the same steel forgings index. Electroslag ingot depends on the quality of electroslag remelting process is reasonable and ensure the electroslag process conditions of equipment.

    Electroslag remelting product variety, wide application. The steel: carbon steel, alloy steel, bearing steel, die steel, high-speed steel, stainless steel, heat-resistant steel, high strength steel, high temperature alloy, precision alloy, corrosion resistant alloy, alloy and other more than and 400 varieties. In addition, the electroslag casting can be directly shaped castings, casting in-s., simplifies the production process, improve the utilization rate of metal.

    Electroslag remelting process fundamentally solve the main contradiction of the general casting process, it combines the electro slag remelting and casting metal - get high quality metallurgical casting special-shaped parts fine blank strengths, and has dense tissue deformation of metal and ordinary casting similar and no characteristics of the anisotropy. Compared with ordinary metal forgings, variant performance index index of Electroslag Remelting Casting can reach the same grade, even to avoid some shortcomings of forging.

In recent years, the new technology of electroslag remelting gradually attracted the attention of domestic and international engineering and technical circles, many industrial departments are stepping up research and use of electroslag remelting products.

    Northeastern University began the development of a new type of mechanical equipment with hydraulic drive and ball screw drive as the core from 1990s to IPC and PLC for hardware, the intelligent computer control system of a new generation of electroslag furnace, there are several sets of equipment applied in domestic industrial production, good use effect.

    Electroslag remelting technology has long been applied in military, the life of tank gun tube is an important symbol to measure the level of a national tank manufacturing. Before our tank gun tube's life is only 100-500, now tank gun tube by electroslag remelting, bore chrome plating technology, the life expectancy of 800-1000, greatly improving the level of military equipment. Electroslag remelting technology will be used more and more in the production of key parts.
