There are two kinds of knotting methods for intermediate frequency thermal induction furnace lining, wet knotting and dry knotting. Both methods can be used for knotting of acid intermediate frequency furnace lining, neutral furnace lining and basic furnace lining.

Intermediate frequency furnace wet knotting refers to the knotting by adding water, water glass, brine and other adhesives to the lining knotting material. Since the knotting material contains a certain amount of water, there is less dust during construction and good formability. However, there are also a series of shortcomings in wet knotting: the lining material knotted in the intermediate frequency furnace is not dense enough, and the refractoriness of the lining decreases; the drying time of the lining is long; the moisture in the lining is gasified. The insulation performance of the furnace decreases. If it is not handled well, it often leads to the breakdown of the inter-turn fire, and may also cause a short circuit to the ground. Therefore, for the larger smelting intermediate frequency furnace, the wet lining should be avoided as much as possible.

The dry furnace building method is currently the most widely used in the furnace building of crucible induction furnaces.Intermediate frequency furnace liningThe dry intermediate frequency furnace construction method without cement can maximize the refractory performance of the furnace lining material, make the sintered layer of the furnace lining thin, thicken the powder layer, reduce the heat dissipation loss of the furnace lining, reduce the tendency of furnace lining cracks, and improve the furnace lining. safety and reliability.
