The new type metal melting induction melting furnace is composed of crucible, furnace body, induction ring and base. The refractory plate at the bottom of the furnace base and crucible is made of refractory cement and high alumina sand, with iron wire as the skeleton. The upper part of the crucible is a circulating cooling water pipe. In the metal melting induction melting furnace of the present utility model, the circulating cooling water pipe in the upper part of the crucible adopts waste

Old induction loop. After the base of the furnace and the lower part of the crucible are made of refractory cement and high alumina sand, a refractory plate made of iron wire as a framework is used in place of asbestos plate, which has low cost and convenient maintenance. The upper part of the crucible uses circulating cooling water pipes to replace the existing special-shaped special refractory bricks, which can evenly cool the crucible, prevent lateral cracks from occurring in the crucible, and facilitate maintenance operations.

Therefore, the utility model has the advantages of low cost, convenient maintenance, uniform cooling, and no transverse cracks in the neck portion.

detailed description

The following is further described with reference to the drawings: the crucible 3 is placed in the furnace body 4, the bottom of the crucible 3 is separated from the furnace body by a base 7, the lower periphery is a refractory plate 6, the base 7 and the refractory plate 6 are low in price and easy to buy The refractory cement is mixed with high alumina sand, with the iron wire as the skeleton. The middle periphery of the crucible is an induction coil 5 which is used for heating. The upper part of the crucible adopts the circulating cooling water pipe 1 made of waste induction coils to replace the existing special-shaped special refractory bricks. In this way, the crucible can be uniformly cooled, the crucible can be prevented from cracking laterally, and maintenance operations are convenient.
