What is an electroslag furnace transformer? Do you know?

1. The electroslag furnace transformer is used for remelting and refining iron and steel products produced by ordinary smelting methods. The copper-type water-cooled crystallizer is injected into the high-temperature liquid slag, and one end of the consumable electrode is inserted into the molten pool, and the slag is integrated into the electrode by the short-term net. , High temperature slag is added to resist heat generation. The gradual heating and condensation of the slag pool can consume the top of the electrode to form metal droplets. These droplets fall from the electrode end and enter the metal molten pool through the slag pool. Due to the cooling effect of the water-cooled crystallizer, Liquid metal gradually forms special-shaped castings.

2. In the process of electroslag refining, the reaction temperature of the steel slag is high, the slag pool is vigorously stirred, and the metal droplets are in full contact with the high basicity slag, which strengthens the interface reaction of the steel slag, and has a better effect of removing phosphorus, sulfur and non-metallic inclusions. Therefore, the purity of the metal and alloy is greatly improved. At the same time, during the solidification process, the slag pool is kept in the high-temperature slag pool above the metal pool, so that the molten metal solidifies sequentially from top to bottom. Therefore, electroslag casting metal The crystal structure is average and precise.

3. Electroslag furnace transformers are widely used, not only for the production of aviation bearing steel, superalloys, resistance alloys, fine alloys, non-ferrous metals, but also for the production of large-scale high-quality alloy ingots, large flat ingots or sheets and other special-shaped castings weighing up to hundreds of tons.
