Problems solved by technology
Doing so will inevitably reduce the strength of the tundish and increase the maintenance cost of the tundish and the cost of refractory materials
Moreover, with the continuous use of the tundish in a high temperature environment, the insulation of the connecting flange will accelerate aging, causing potential danger to induction heating production

Embodiment 1
[0014] Such as figure 1 As shown, the device is composed of a power supply device 1, a tundish 2, an electromagnetic induction coil A3, a refractory wall 4, an electromagnetic induction coil B5, a tundish steel cavity 6, and an induction channel 7, wherein the casting cavity of the tundish 2 and The tundish steel cavity 6 is an integrated steel body, which does not require flange connection, and thus does not require insulating materials. The casting cavity of the tundish 2 and the interior of the tundish steel cavity 6 are separated by a refractory wall 4, and the refractory wall An electromagnetic induction coil A3 and an electromagnetic induction coil B5 are arranged inside the body 4, and induction channels 7 are respectively arranged on both sides of the two electromagnetic induction coils (according to the actual space of the tundish and the flow of molten steel, the induction channels between the two coils can be two , can also share one), the electromagnetic induction ...

The invention relates to a high-efficiency electromagnetic induction heating device for molten steel in a tundish. The high-efficiency electromagnetic induction heating device comprises the tundish, a fireproof wall body, electromagnetic induction channels, an electromagnetic induction coil A, an electromagnetic induction coil B, a steel bearing cavity of the tundish and a power supply device. A steel body of a casting cavity and a steel body of the steel bearing cavity of the tundish are overall integrated; the inside of the steel bearing cavity and the inside of the casting cavity of the tundish are isolated through the fireproof wall body; the two electromagnetic induction coils are arranged in the fireproof wall body, and the electromagnetic induction channels are arranged on the two sides of the electromagnetic induction coils so that the steel bearing cavity and the casting cavity of the tundish can be communicated; the two electromagnetic induction coils are in series connection with the power supply device. According to the high-efficiency electromagnetic induction heating device for the molten steel in the tundish, a closed-loop iron core is arranged in the tundish, the two electromagnetic induction coils are in series connection with the iron core, as a result, the problem that an outer shell of the tundish emits heat due to flux leakage when an electromagnetic induction heating device is additionally arranged in the tundish is solved, and the problems of flow fields and insufficient space also can be solved.
Description
technical field [0001] The invention relates to an electromagnetic induction heating device for high-efficiency tundish molten steel. Background technique [0002] Installing an electromagnetic induction heating device in the tundish to realize temperature compensation of molten steel and removal of inclusions is a very ideal means of temperature compensation and refining of molten steel in the tundish, especially when the induction heating device compensates for the temperature of molten steel, Can effectively remove small non-metallic inclusions below 50μ. Since the shell of the tundish is conductive and magnetic, the common induction heating device needs to divide the tundish into two parts, the two bodies are connected by flange, and the flange connection is isolated by insulating material to isolate the induced current formed in the shell of the tundish. , so that the tundish will not generate heat during use. Doing so will inevitably reduce the strength of the tundis...
