Melting furnace induction coil description

The induction coil of the melting furnace is optimized by the special computer software according to the user's proposed process parameters, which can ensure the best electromagnetic coupling efficiency under the same capacity. The entire inductor is constructed with a prefabricated assembly for easy maintenance and consumable replacement. The furnace lining is the first in China, with an advanced level of knotted furnace lining, and its refractoriness is ≥1750 °C. The coil is made of high-quality large-section rectangular copper tube. The inside of the tube is cooled by water. The surface of the copper tube is treated by electrostatic spraying epoxy, which can achieve Class H insulation. To protect its insulation strength, the surface of the coil is coated with moisture-proof insulating enamel. .Then fix a whole. The induction coil is fixed by a series of bolts and insulating stays welded to its outer circumference. After the coil is fixed, the pitch error of the coil is not more than 0.5 mm.After the entire inductor is fabricated, it becomes a rectangular parallelepiped, which makes it more shock-resistant and holistic.

There are water-cooled furnace mouth copper plates at both ends of the furnace body. The stainless steel quick-change joint is used for the inlet and outlet of the furnace body, which can facilitate the replacement and maintenance of the furnace body.

The water connection is a quick connector. For reliable electrical connection and quick replacement, a large stainless steel bolt connection is used. Simply replace the bolt and open the water fitting locking device when replacing.

Water quick-change joint : In order to change the convenience of the furnace body, a quick-change joint is adopted in the design of the pipeline joint, and the material of the quick-change joint is selected from stainless steel of grade 316. Mainly composed of threaded interface parts, hose interface parts, fastening wrenches, sealing washers, etc. The most important feature of this quick-change joint is that the threaded interface parts and the hose interface parts can be matched with each other, and the fastening of the wrench is convenient and the sealing performance is good.

Stove

It is a welded steel component, internal water-containing road, electrical appliances, pneumatic components, capacitor channel copper busbars, etc.

Refractory clay

The coil cement is made of refractory clay for the United States coal ore smelting furnace coil, which has the characteristics of good strength, high temperature resistance and good insulation. In addition to effectively ensuring the insulation between the turns of the coil, it also plays a significant role in the insulation of the furnace body, especially for the heating of large workpieces.
