Abstract
The utility model provides a magnet yoke device of an intermediate frequency induction melting furnace. A group of induction coil connectors are arranged on the outside of an induction coil copper pipe of a crucible, at least three longitudinal induction coil insulation stand columns are arranged on the outside of the induction coil copper pipe, an insulation material layer is arranged between the induction coil copper pipe and a ferrite magnet yoke, the ferrite magnet yoke is arranged on at least one of the inside and the outside of the induction coil copper pipe, and the ferrite magnet yoke is arranged between two induction coil bakelite stand columns on the outside of the induction coil copper pipe. The magnet yoke is light in weight, does not need water communication, can effectively shield the magnetic field outside an induction coil, is safe and reliable in operation, saves electricity and water, and is convenient to install and maintain and low in cost.
Description
Technical field:
The utility model relates to a kind of medium frequency induction melting furnace, especially a kind of yoke device of medium frequency induction melting furnace.
Background technology:
At present, in the medium frequency induction melting furnace process of using,, exist by the problem of induction heating because shell is a metal.In order to solve the problem of shell heating, a lot of smelting furnace shells are made aluminum hull, reduce the generation of caloric value.But aluminum hull intensity after all is limited, when having runout, and problem such as shell fusing can occur or split; Present increasing smelting furnace shell is made outer steel shell; In order to guarantee that box hat is not fallen by induction melting, a kind of is exactly to adopt logical cooling water to come cooled enclosure, but power consumption can roll up like this; The yoke that the another kind of water-cooled silicon steel sheet that makes a circle in the induction coil outside is exactly made is come armoured magnetic field, prevents the shell heating.Silicon steel sheet has approached, and does not have the purpose of armoured magnetic field, and weight that silicon steel sheet is too thick is very big, can cause and turn over the stove difficulty, be unfavorable for drawbacks such as maintenance.Simultaneously, because the silicon steel conduction causes silicon steel sheet induction heating, so the also necessary water flowing cooling of silicon steel, still, water-cooled structure is very complicated, has the problem of power consumption simultaneously.In view of above-mentioned many reasons, need to improve the device of medium frequency induction melting furnace armoured magnetic field.
The utility model content
The utility model through rational design, provides a kind of yoke device of medium frequency induction melting furnace for the conduction of the silicon steel shell that solves the medium frequency induction melting furnace aluminum hull, the power consumption that the induction heating brings, and is non-conductive, non-inductive heating; Practice thrift maintenance cost and electric power resource, saved manpower, prolonged service life.
The utility model is in order to realize above-mentioned goal of the invention; Adopt following technical scheme: a kind of medium frequency induction melting furnace yoke device; Be by one group of induction coil joint of induction coil copper pipe arranged outside of crucible; At least three induction coil insulation longitudinally of induction coil copper pipe arranged outside column, the induction coil copper pipe is provided with insulation material layer between ferrite yoke; Between two induction coil bakelite columns in the induction coil copper pipe outside ferrite yoke is set.
Beneficial effect: this yoke very light in weight, do not need water flowing, and can effectively shield the magnetic field in the induction coil outside, safe and reliable to operation, energy-saving and water-saving is convenient to installation and maintenance, and is with low cost.
This device adopts the bonding one-tenth of this permeability magnetic material of ferrite magnetic stripe fan-shaped, encloses the periphery of induction coil and forms yoke.Because the Ferrite Material magnetic flux is more much bigger than silicon steel sheet; So very thin ferrite yoke just can well shield the magnetic field in the induction coil outside; The shell that guarantees the induction coil outside is not generated heat by induction, weight have only equal effect silicon steel sheet about 1/10th.Ferrite is a kind of electrically non-conductive material simultaneously, can not generate heat because of induction, so do not need water cooling system.By the fan-shaped block ferrite yoke of the bonding one-tenth of Ferrite Material, be evenly distributed on the periphery of induction coil copper pipe at interval, insulation material layer is filled in the middle of induction coil copper pipe and the yoke.The induction coil insulated column altogether the six roots of sensation, induction coil joint totally four and induction coil copper pipe form the induction coil structure jointly, insulation material layer can be materials such as bakelite plate, tetrafluoro plate, asbestos packing sheet.The material of this yoke is a ferrite, and shape is not limited to a kind of shape; The installation site of this yoke is positioned at the periphery of induction coil, and the structure of said induction coil is not limit said structure, can be other structures yet.At least a type of cooling of this yoke.
