Technical Field

The utility model relates to a molten metal treatment furnace technical field, concretely relates to molten metal treatment furnace adds thermal refining agitating unit.

Background

In the industries of iron and steel works, casting and the like, ferrous and nonferrous metals are refined, decontaminated and components-adjusted for various molten metals, especially in the aspect of special metal treatment. In the process of producing the special metal, although the prior art is mature in process technology, the equipment group is huge, the investment is large, and the miniaturization is difficult. For example, when a molten metal is treated by a molten metal treatment furnace in the prior art, the molten metal cannot be stirred, heated and tempered, and the operation needs to be performed by the next process, so that the equipment investment is large, and a certain burden is caused to the enterprise cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the problem that exists among the prior art, provide a molten metal treatment furnace heating quenching and tempering agitating unit, it can realize solving the problem among the prior art to a certain extent at least.

In order to realize the technical purpose, the technical effect is achieved, the utility model discloses a realize through following technical scheme:

the utility model provides a molten metal treatment furnace heating quenching and tempering agitating unit, includes the furnace of molten metal treatment furnace, two liang of nonmetal backing plates of multiunit are equipped with in pairs on the furnace outer wall, the cover is equipped with a plurality of iron cores on the furnace, the iron core outline roughly becomes the U-shaped, and its two horizontal segments correspond nonmetal backing plate respectively, and the winding is equipped with multiunit coil on the vertical section in the middle of it, the coil is supplied power by outside alternating current power supply.

Furthermore, the iron core corresponds to the middle position of the hearth.

Further, the iron cores are four.

Further, the non-metal backing plate is connected to the outer wall of the hearth through screws.

The utility model has the advantages that: the coil is last to be led to with the alternating current of low frequency, can produce the magnetic field that changes around the coil, and the route of magnetic line of force has been constituteed jointly to the metal liquid in outside iron core and the furnace, and the iron core is the magnetizer, and the magnetic resistance is little, and it is few to generate heat, and metal liquid magnetic resistance is big, can produce vortex heat and electromagnetic force, stirs the metal liquid, reaches the purpose of stirring and heating metal liquid, prior art relatively, the metal liquid treatment furnace overall structure in this application is compact, and manufacturing cost is lower.
