Why do the lining of induction heating furnace often knot

At present, there are basically two types of lining assembly of cuptoare de incalzire cu inductie, one is knotted lining, and the other is assembled lining.

1. Whether it is knotted lining or fabricated lining, long-term work under high temperature will change (mainly thermal expansion and contraction and oxidation). If used improperly, the heating material will collide and squeeze the furnace lining. Therefore, the use of the furnace lining has a certain period of time. This mainly depends on the situation during use.

2. Once the furnace lining cracks, if it is a knotted lining, it must be filled with knotting material if the crack does not exceed 2mm. If the crack exceeds 2mm, the lining must be knotted again; if it is a fabricated lining, it must be replaced. Therefore, the user must take the necessary measures in the actual situation, and do not act hastily, causing unnecessary consequences and burning the sensor.
