Abstract
The utility model discloses a kind of electric melting magnesium furnace and filling-material structure, and three root graphite electrodes are arranged in furnace wall, secondary feeding ring are arranged on the outside of furnace wall, the secondary feeding ring is arranged in the support ring on the outside of furnace wall；The discharge port distal end of secondary feeding ring is no more than the circumcircle of three root graphite electrodes；The delivery outlet of feed cylinder is arranged in the top of secondary feeding ring；The bottom of secondary feeding ring is to be obliquely installed, and the height in outside is more than the height of inside.The utility model has the advantages that：As a result of rotatable feed way, material is fed directly near graphite electrode, ensure that secondary material is in direct contact with electrode, in this way, electric smelting effect is preferable, product quality is greatly improved.
Description
Technical field
The utility model is related to fused magnesite Preparation equipment, specifically a kind of electric melting magnesium furnace.
Background technology
Fused magnesite is made by fusing using quality magnesia as raw material, which has purity high, and crystal grain is big, knot
Structure is fine and close, and the strong material of resistance to slag, good thermal shock stability is a kind of excellent high temperature electrical insulation material, and makes high-grade magnesium
The important source material of brick, magnesia carbon brick and unshape refractory.And during preparing fused magnesite, the furnace charge in magnesium stove is melted primary
It can may not completely be melted after melting, have the furnace charge that some are not melted completely through being thrown away frequently as waste product, this not only causes to waste,
And also add production cost；In addition, during charging, feeds from charge door due to the use of conveyer belt, often result in charging
Uneven, this is also to cause to melt one of incomplete reason.Optimal feed way is that graphite electrode nearby adds secondary material,
Secondary material, which was arranged in the reason of surrounding them, is：Due to not melting completely in previous fusion process, it is anti-to produce some
Fusant, when secondary electric smelting, need higher temperature, this kind material is arranged in surrounding them, improves solution temperature as far as possible, favorably
In melting；During the secondary material once melts magnesium before referring to, the magnesium material not melted completely, also referred to as red white material.And secondary material and
Tweer adds a defective material, and a defective material is the address relative to secondary material, refers to the raw material melted for the first time.
Existing electric melting magnesium furnace is unable to reach above-mentioned technique effect.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of electric smelting that above-mentioned technique effect can be achieved
Magnesium stove, specific technical solution are：
A kind of electric melting magnesium furnace and filling-material structure are arranged three root graphite electrodes in furnace wall, secondary feeding ring are arranged on the outside of furnace wall,
The secondary feeding ring is arranged in the support ring on the outside of furnace wall；The discharge port distal end of secondary feeding ring is no more than three graphite electricity
The circumcircle of pole；The delivery outlet of feed cylinder is arranged in the top of secondary feeding ring；The bottom of secondary feeding ring is to tilt to set
It sets, and the height in outside is more than the height of inside.
Manual mode can be used in the rotation of the secondary feeding ring, therefore, is fixed with and turns on the outside of the secondary feeding ring
Dynamic handle.It is, of course, also possible to using motor-driven mode.
The utility model has the advantages that：As a result of rotatable feed way, it is attached that material is fed directly to graphite electrode
Closely, it ensure that secondary material is in direct contact with electrode, in this way, electric smelting effect is preferable, product quality is greatly improved.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the positions the A-A schematic cross-section of Fig. 1.
Specific implementation mode
The utility model is illustrated below in conjunction with the accompanying drawings, as shown, three root graphite electrodes 1, furnace wall are arranged in furnace wall 2
2 outsides are arranged secondary feeding rings 5, in the support ring 10 that the secondary feeding ring 5 is arranged on the outside of furnace wall；Secondary feeding ring 5
The distal end of discharge port 6 is no more than the circumcircle 9 of three root graphite electrodes；The delivery outlet 8 of feed cylinder 7 is arranged in secondary feeding ring
5 top；The bottom 6 of secondary feeding ring is to be obliquely installed, and the height in outside is more than the height of inside.
Manual mode can be used in the rotation of the secondary feeding ring, therefore, is fixed with and turns on the outside of the secondary feeding ring
Dynamic handle.It is, of course, also possible to using motor-driven mode.
In Fig. 1, region 3 is that secondary material adds area, and region 4 is that a defective material adds area.
Secondary material was arranged in the reason of surrounding them the utility model：Due to not melting completely in previous fusion process
Change, therefore, produce some anti-fusants, when secondary electric smelting needs higher temperature, this kind material is arranged in surrounding them, to the greatest extent may be used
Solution temperature can be improved, is conducive to melt.
Claims (2)
1. a kind of electric melting magnesium furnace and filling-material structure, it is characterised in that：Three root graphite electrodes are set in furnace wall, are arranged two on the outside of furnace wall
Secondary feeding ring, the secondary feeding ring are arranged in the support ring on the outside of furnace wall；The discharge port distal end of secondary feeding ring is no more than
The circumcircle of three root graphite electrodes；The delivery outlet of feed cylinder is arranged in the top of secondary feeding ring；The bottom of secondary feeding ring
Portion is to be obliquely installed, and the height in outside is more than the height of inside.
