Advantages and disadvantages of induction melting furnace and its application
Compared with cupola smelting, the advantage of induction melting furnace smelting is that there is no carbonation and sulfur increase during the smelting process, and the smelting process can cover the molten iron with slag, and to some extent prevent silicon and manganese in the molten iron. Oxidation of alloying elements and reduction of the absorption of gas from the furnace gas by the molten iron, so that the molten iron is relatively pure. The disadvantage of this smelting method is the large energy consumption.
The induction melting furnace is suitable for smelting high quality gray cast iron, alloy cast iron, ductile iron and compacted graphite cast iron. The coreless induction melting furnace is capable of directly melting the solid charge, and is convenient to open and shut down, and is suitable for intermittent production conditions. The core induction melting furnace is inconvenient to open and shut down, and is suitable for continuous production. The furnace has a low thermal efficiency for melting the solid charge and a high thermal efficiency for the hot iron, so it is suitable for use with a cupola. Both forms of induction melting furnaces are now used in cast iron production.
