What is the temperature of the steel bar induction heating furnace lining?

The temperature of the steel bar induction furnace lining. In the heating of the steel rod induction heating furnace, the furnace head, which is also called the inductor, plays an absolute role. The inductor is a spiral coil wound by a rectangular copper tube. The furnace lining is to protect the induction coil and reduce heat dissipation. Therefore, the temperature resistance of the steel bar induction heating furnace lining is very important. Generally speaking, the heating temperature of steel bar induction heating furnace does not exceed 1200 degrees, which requires the temperature resistance of the furnace lining to be 1350 degrees. Commonly used furnace linings are silicon carbide lining tubes and refractory knotting. The silicon carbide furnace lining tube can be wound with aluminum silicate wool and then directly put into the induction coil, which is simple and convenient, but has a short service life and needs to be replaced frequently; while the furnace lining is knotted using castables such as quartz sand, and the furnace lining is poured according to a certain size. The coil is vibrated and dried after knotting, and an oven procedure is required before use. The disadvantage is that it is troublesome to tie knots, but the service life is long.
