Abstract
The utility model discloses an iron core structure of an electric slag furnace transformer. The iron core structure of the electric slag furnace transformer comprises an iron core (1) made of a silicon steel sheet, and is characterized in that an upper cavity of the iron core (1) is shaped like an inverted prismoid, the included angle between the inclined plane of the inner wall at the upper portion of the iron core (1) and the horizontal plane is 35-60 degrees. The cavity shaped like the inverted prismoid is formed in the upper portion of the iron core, so that the magnetic flow direction of the iron core and the rolling direction of the silicon steel sheet are the same, and loss in the no-load process is reduced. The iron core structure of the electric slag furnace transformer has the advantages of being simple in structure, convenient to machine, and suitable for popularization and use.
Description
Technical field
The utility model relates to a kind of core structure of electroslag furnace transformer.
Background technology
The electroslag furnace transformer is for specializing in the electroslag furnace power supply that aviation is held steel, high temperature alloy, electric resistance alloy, Precise Alloy, some non-ferrous metal and produced large-scale high duty alloy steel ingot, large-scale slab ingot, slab, other special special-shaped casts etc.The core structure of existing electroslag furnace transformer, because it is moulded consistent, cause the rolling direction of its flow direction and silicon steel sheet perpendicular, and while causing zero load, loss value is larger.
Summary of the invention
The purpose of this utility model is the problem existed for prior art, and the core structure of the electroslag furnace transformer that when rolling direction of a kind of flow direction and silicon steel sheet is identical makes zero load, loss value reduces is provided.
The purpose of this utility model solves by the following technical programs:
A kind of core structure of electroslag furnace transformer, comprise the iron core that silicon steel sheet is made, and it is characterized in that the upper cavity of described iron core is down prism-frustum-shaped.
The angle that the inclined-plane of described iron core upper inside wall becomes with horizontal plane is 35 °-60 °.
The utility model has the following advantages compared to existing technology:
The utility model, by arrange the cavity of prism-frustum-shaped on the top of iron core, makes the flow direction of iron core identical with the rolling direction of silicon steel sheet, has reduced loss value when unloaded, has characteristics simple in structure, easy to process, suitable promoting the use of.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-iron core.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of core structure of electroslag furnace transformer, comprise the iron core 1 that silicon steel sheet is made, it is 35 °-60 ° that the upper cavity of this iron core 1 is down the angle that the inclined-plane of prism-frustum-shaped and iron core 1 upper inside wall becomes with horizontal plane.
The utility model, by arrange the cavity of prism-frustum-shaped on the top of iron core 1, makes the flow direction of iron core identical with the rolling direction of silicon steel sheet, has reduced loss value when unloaded, has characteristics simple in structure, easy to process, suitable promoting the use of.
Above embodiment is only explanation technological thought of the present utility model, can not limit protection range of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on the technical scheme basis, within all falling into the utility model protection range; The technology that the utility model does not relate to all can be realized by prior art.
Claims (2)
