Abstract
The utility model discloses a water cooling pedestal for oxygen lance. The room made up by the wall of the pedestal is an internal room and a muzzle is arranged on the wall of the pedestal; the internal room is communicated with the outside through the muzzle; an internal drop ply is developed in the internal room and cooling medium is arranged inside the internal drop ply; the wall of the pedestal comprises at least an outer layer and an inner layer; the internal drop ply is arranged inside the inner layer of the wall of the pedestal. The outer layer of the wall of the pedestal is made of copper and the inner layer is made of steel. The water cooling pedestal ensures thermal conductivity and oxidation resistance of the water cooling pedestal and at the same time greatly reduces production cost.
Description
Technical field
The utility model belongs to a kind of arc furnace equipment, is specifically related to a kind of oxygen gun water-cooling seat.
Background technology
Generally be equipped with the oxygen gun water-cooling seat on the cooled plate of furnace shell furnace wall on the existing electric arc furnaces, be used for fixing and protect the oxygen rifle, because the poor working environment of oxygen gun water-cooling seat, aspect the material use of oxygen gun water-cooling seat, forge dozen red copper material and have characteristics such as good heat-transfer, the erosion of oxytolerant gas cut, be widely used; And the oxygen gun water-cooling seat of electric arc furnaces factory use at present all adopts fine copper to be made; This structure mainly contains following defective:
1, the whole fine copper that adopts of oxygen gun water-cooling seat is made about 100,000 RMB of the cost of every water-cooled seat, manufacturing cost height;
2, during smelting, the oxygen rifle stretches out from muzzle, is smashed by steel scrap easily, and simultaneously, hot environment can reduce the service life of oxygen rifle.
Summary of the invention
The purpose of this utility model is to provide a kind of oxygen gun water-cooling seat of low cost of manufacture.
The utility model is achieved by the following technical solution:
A kind of oxygen gun water-cooling seat, seat a space that wall enclosed is interior space, and present wall is provided with muzzle, and interior space communicates with the external world by this muzzle, and is empty and dead level in forming is equipped with cooling medium in this interior dead level in the seat wall; Described wall comprises the outer and seat wall internal layer of the seat wall that pastes mutually at least, and described interior dead level is positioned at this wall internal layer.
In the utility model, the seat wall comprises that at least a wall skin, seat wall internal layer are two-layer, at this moment, the outer available copper of seat wall is made, internal layer can adopt general material (as being formed from steel), strong, the good in oxidation resistance of the outer thermal conductivity of seat wall, and seat wall internal layer can adopt common material to make, and has significantly reduced manufacturing cost.
Further structure of the present utility model is:
Be with graphite bushing on described muzzle, further, described graphite bushing is provided with flange near an end in space in described, and the outer end of described graphite bushing protrudes from described muzzle.This graphite bushing plays a protective role to the oxygen rifle, avoids steel scrap to smash the oxygen rifle, has also reduced heat and has transmitted in the oxygen rifle.
The outer field thickness of described seat wall is 4mm to 8mm, and the thickness of described seat wall internal layer is 15mm to 25mm.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of oxygen gun water-cooling seat, seat a space that wall enclosed is interior space, and present wall is provided with muzzle, and interior space communicates with the external world by this muzzle, and is empty and dead level in forming is equipped with cooling medium in this interior dead level in the seat wall; Described wall comprises the outer and seat wall internal layer of the seat wall that pastes mutually, and described interior dead level is positioned at this wall internal layer; Be with graphite bushing on muzzle, graphite bushing is provided with flange near an end in interior space, and the outer end of graphite bushing protrudes from muzzle.
In the utility model, the seat wall of oxygen gun water-cooling seat adopts seat wall skin, seat wall internal layer double-layer structure, during manufacturing, seat wall skin is made by fine copper, its thickness is 6mm, and seat wall internal layer is formed from steel, and its thickness is 20mm, pedestal outer wall thermal conductivity, good in oxidation resistance, the material cost of total significantly reduces simultaneously; Graphite bushing plays a very good protection to the oxygen rifle.
