Reasons for the leakage of induction melting furnace

A common accident in the furnace body of an induction melting furnace is leaking through the furnace. If there is an accident, if no measures are taken, it will cause the copper tube of the coil to rupture, and the molten iron and the coolant will explode. s reason:

1. Quality factors of materials used in furnace construction: generally use quartz acid furnace lining materials. The silicon content of quartz sand and quartz powder should be above 99.5%, with oily crystals, transparent and free of impurities. Generally use high-purity quartz sand (silicon content 99.85%, hardness 8, density 2.65, refractoriness 1850 degrees).

2. Binder factors used in furnace construction: traditional furnace construction methods generally use boric acid as a binder. Boric acid has both advantages and disadvantages: the advantage is that the bonding is fast at low temperature, generally starting at 600-700 degrees; the disadvantage is that it is not resistant to high temperature and erosion. Under high temperature conditions, the lower part of the furnace wall will cause the phenomenon of boiling , The number of heats used is greatly reduced. It is recommended to use boric acid as a binder, because boric acid has the characteristics of high temperature bonding, high melting point, high temperature resistance, and erosion resistance.
