Electroslag casting technology adopts metal mold casting, which is a high-quality metal forming process developed based on electroslag remelting technology, and completes the refining and forming of castings at the same time, known as green casting technology. Like AOD or VOD, electroslag casting is a refining process. However, compared to this, the entire process of electroslag casting is carried out inside the metal mold, which can avoid secondary pollution caused by the contact between molten steel and air, sand molds, etc. during casting and pouring in refining processes such as AOD or VOD.
The process of electroslag casting combines refining and forming of molten steel. The melting process can reduce the impurity content in the material, improve the purity of the material, and due to the rapid cooling method used in the casting forming process, the grain size of the resulting casting is very small, which can effectively improve the ability to resist crack lines and crack propagation. Castings produced using electroslag casting technology can meet the testing requirements of any standard in the world, such as CCH 70-4 and ASTM A609 standard level one. The guide vanes produced by SSSF have a long service life and good safety.
