What are the common lining methods for intermediate frequency furnaces? Here, with the small edition of Hubei batcher manufacturers to understand it!

There are two knotting methods for intermediate frequency hot induction furnace lining: wet knotting and dry knotting. Both methods can be used for acidic intermediate frequency lining, neutral lining and basic lining.

Intermediate frequency furnace wet knotting refers to the knotting by adding water, water glass, brine and other adhesives into the knotting material of the furnace lining. Because the knotting material contains certain moisture, it has less dust and good formability during construction. However, wet knotting also has a series of shortcomings: the lining material of intermediate frequency furnace knotting is not dense enough, and the refractoriness of the lining has decreased; The drying time of the lining is longer. When the moisture in the furnace lining vaporizes, the edge performance of the sensor decreases. Poor treatment often leads to the breakdown of the inter-turn fire, and may also cause the grounding short circuit, therefore, for the larger melting medium frequency furnace should try to avoid the use of wet knotting furnace lining.

Dry furnace construction method has been widely used in the furnace construction of crucible induction furnace. The dry medium frequency furnace construction method without cementing agent can give full play to the fire resistance of the lining material, make the sintered layer of the lining thinner, the powder layer thicker, the heat loss of the lining reduced, the tendency of the lining crack reduced, and the safety and reliability of the lining improved.
