Abstract

The utility model discloses a ring hearth for a large-power cascading inductor. The ring hearth comprises a ring hearth body which includes two parallel ring hearths; the middle parts of the two ring hearths are connected into a whole; the inductor is powered by a single-phase electric source; and when connecting wires, the two ring hearths are connected in parallel. When the ring hearth is in work, metal flows quickly in the ring hearth and no superheat phenomena exist in the ring hearth; and the inductor is long in service life.

Description

High-power spray pattern inductor channel

Technical field

The utility model relates to a kind of induction heating device, specifically a kind of high-power spray pattern inductor channel.

Background technology

Common transformer and power supply and load can be formed an electric appliance circuits, as shown in Figure 1.Wherein transformer output winding is a multi-turn, is as the criterion to satisfy rated voltage with load.In non-ferrous metal industry, the mode of the existing heat fused metal of using always is an induction heating, forms the part of heater behind its metal molten.Before metal did not melt, we are a pre-buried metallic object ring-like or the U type, that material is identical with being heated metal, i.e. said channel in the sector in smelting furnace usually.Different with the ordinary appliances circuit, the transformer output winding of this induction heater is a circle, so form the circuit (as shown in Figure 2) of a low-voltage and high-current.Above-mentioned channel is exactly the output winding in this circuit.If supply with enough high-power ac powers, under the lotus root cooperation of transformer core was used, the winding of output (channel) will form powerful electric current, under the thermal effect effect of electric current, just can make metal molten.Existing induction heater has characteristics such as single inductor power is big, iron loss is little.But existing high-power spray pattern inductor is because its U type channel inner metal liquid temperature generally exceeds 120～160 ℃ than burner hearth molten metal temperature, heavy in section channel inner metal liquid temperature also exceeds more than 80 ℃ than burner hearth molten metal temperature, like this, molten metal is reaching under the temperature conditions of technological requirement, temperature in the channel of its underpart is high more a lot of than technological temperature, too high because of the temperature at this position, can cause whole body of heater to produce superheating phenomenon, and then can have influence on the useful life of inductor.

Summary of the invention

Technical problem to be solved in the utility model is to propose a kind of metal and flows in channel and do not have the high-power spray pattern inductor channel of superheating phenomenon, inductor long service life in fast, the channel.

For solving the problems of the technologies described above, the high-power spray pattern inductor of the utility model channel comprises the channel body, and two ditches that described channel body is made of side by side two channels fuse in the middle of these two channels, described inductor is a single phase power supply, and described two channels are parallel with one another during wiring.

Above-mentioned high-power spray pattern inductor channel, described two channels are annular channel, and whole channel is " ω " shape.

Because the extruding force of metal is to form metal directed flow, extruding force F=KI in the channel ²/ S.The electric current of the middle channel of the utility model spray pattern inductor channel is 2 times of side channel, and area is 1～2 times of a side channel, so the extruding force of middle channel is more than 2 times of side channel.Under the powerful extrusion force effect, the quick molten metal that channel advanced, the both sides channel goes out in the middle of the metal in the channel can form flows.Because it is fast that metal flows in channel, thereby metal time of staying in channel is short, and the channel inner metal liquid generally only exceeds 20～40 ℃ (its concrete data are different and different with the inductor design according to smelting metal kind and channel shape) than the burner hearth molten metal.Therefore, there is not superheating phenomenon in the channel, the inductor long service life.
