Problems solved by technology

In the existing electromagnetic melting furnace, the coil is set on the outside of the crucible, and the molten material is placed inside the crucible, and electromagnetic heating is used to heat the molten material. Since the outer surface area of ​​the crucible is larger than the inner surface area, this heating method uses the inner surface Heating, relatively speaking, the heating area is small, at the same time, the outer surface is exposed to the environment, the heat dissipation area is also large, the heat loss is fast, and the heat utilization rate is very low

Abstract

The invention discloses a novel electromagnetic melting furnace, which is characterized in that the melting furnace includes a heater and a furnace body, the heater is erected on the bottom boss of the molten pool formed by the furnace body, and the heater includes a coil , an insulation layer and a heating body, the insulation layer is attached to the inner wall of the heating body to form a semi-open insulation layer cavity, and the coil is spirally wound into a coil group with multiple turns, which is suitable for disposing in the insulation layer cavity. In the present invention, by placing the coil of the heater inside the heating body and using the outside of the heater as the heating surface, the heating area of ​​the heater is increased, the heat dissipation area of ​​the heater is reduced, the heat utilization rate of the furnace is improved, and resources are reduced. waste.

Description

technical field [0001] The invention relates to the field of heating equipment, in particular to a novel electromagnetic melting furnace. Background technique [0002] There are two main types of traditional industrial furnaces: one is to use fuel combustion to heat up the furnace, and the other is to use electric heating tungsten wire to heat the pot body. These two existing furnace heating methods all need to heat up the pot body first, and then use the heat of the pot body to heat the melted objects in the pot body melting furnace through heat conduction. In the existing electromagnetic melting furnace, the coil is set on the outside of the crucible, and the molten material is placed in the crucible, and electromagnetic heating is used to heat the molten material. Since the outer surface area of ​​the crucible is larger than the inner surface area, this heating method uses the inner surface For heating, relatively speaking, the heating area is relatively small, and at th...
