Description

A kind of oxygen rifle brick structure

Technical field

The utility model belongs to metal smelt technical field, is specifically related to a kind of oxygen rifle brick structure.

Background technology

Bath smelting smelting technique is widely used in the converter of oxygen-enriched bottom-blowing and oxygen-enriched side-blowing, the oxygen rifle used under this technique needs periodic replacement, need remove oxygen rifle brick when replacing oxygen rifle, high temperature is in for a long time owing to adopting the oxygen rifle brick of this technology, the environment of high corrosive medium, oxygen rifle brick is under physicochemical effect, originally the polylith rifle brick of close installation merges at one piece, and combine with the peripheral brick that encloses, consuming time many during dismounting, and easily the brick that encloses of periphery is damaged, repeated multiple times dismounting, the out-of-flatness of enclosing brick surface can be caused, brickwork joint produces gap, although can repair with high temperature pouring material, but the liquation in molten bath washes away repeatedly, finally repair layer can be washed off, cause the leakage of stove inner melt, produce industrial accident, cause producing and stop production.

Summary of the invention

In order to solve the problems of the prior art, the utility model proposes one and can solve oxygen rifle brick and oxygen rifle encloses adhesion between brick, when avoiding removing oxygen rifle brick, the oxygen rifle brick structure that brick damages is enclosed to oxygen rifle.

In order to realize above object, the technical scheme that the utility model adopts is: comprise oxygen rifle brick, and be nested in oxygen rifle brick week oxygen rifle to the periphery and enclose brick, oxygen rifle brick is offered aerobic rifle pilot hole, oxygen rifle brick and oxygen rifle enclose in the gap between brick and are filled with mica paper.

Described oxygen rifle brick is wedge shape.

Described oxygen rifle brick is spliced by 7 blocks of refractory brick.

The refractory brick of described oxygen rifle brick is filled with mica paper in gap each other.

The thickness that described mica paper is filled is 0.2 ~ 0.5mm.

The refractory temperature of described mica paper is more than or equal to 1000 DEG C.

Described mica paper is pasted onto on oxygen rifle brick by high temperature glue.

Described oxygen rifle pilot hole runs through oxygen rifle brick along oxygen rifle brick axis direction.

Compared with prior art, the utility model encloses between brick at oxygen rifle brick and oxygen rifle and adds mica paper, because mica has the character of higher refractory temperature, itself material is different with refractory brick again, sealed oxygen rifle brick and oxygen rifle can enclose gap between brick, pass through this medium by separated between brick and brick simultaneously, finally can not combine together, brick brick face is enclosed in oxygen rifle brick brick face and oxygen rifle by the mica paper on oxygen rifle brick surface to be isolated, in use adhesion can not be produced, because every block brick is relatively independent, as long as dismantle one piece, other brick is just easy to remove, and dismounting back wall brick surrounding is smooth, repeatedly change, enclose brick brick face still intact.

Further, oxygen rifle brick is that wedge shape is convenient to be arranged in the converter of bath smelting.

Further, oxygen rifle brick is spliced by 7 blocks of refractory brick, is convenient to remove, and 7 pieces of refractory brick splicing composition wedge shapes are convenient to install.

Further, mica paper is added between the refractory brick of oxygen rifle brick, because mica has higher refractory temperature, itself material is different with refractory brick again, can either gap between the refractory brick of sealed oxygen rifle brick, by this medium by separated between refractory brick and refractory brick, can not be able to combine together in use procedure simultaneously.When dismounting, because every block refractory brick is relatively independent, as long as dismantle one piece, other brick is just easy to remove, and it is smooth to remove back wall brick surrounding, repeatedly changes, and it is still intact to enclose brick brick face.

Further, the thickness that mica paper is filled can ensure that sealed oxygen rifle brick and oxygen rifle enclose the gap between brick, and oxygen rifle brick gap each other, can separate simultaneously, ensure that the stability of device by between brick and brick.

Further, the refractory temperature of mica paper ensure that mica paper can adapt to hot environment, ensure that the performance of use.

Further, utilize high temperature to water stickup mica paper, that pastes in high temperature environments is firm, ensure that the stability of total, improves serviceability.

Detailed description of the invention

Below in conjunction with embodiment, the utility model is described in further detail.

See Fig. 1, Fig. 2 and Fig. 3, the utility model comprises oxygen rifle brick 1, and be nested in oxygen rifle brick 1 week oxygen rifle to the periphery and enclose brick 2, oxygen rifle brick 1 is offered aerobic rifle pilot hole 3, oxygen rifle pilot hole 3 runs through oxygen rifle brick 1 along oxygen rifle brick axis direction, and oxygen rifle brick 1 and oxygen rifle enclose in the gap between brick 2 and be filled with mica paper 4, and the thickness that mica paper 4 is filled is 0.2 ~ 0.5mm, the refractory temperature of mica paper 4 is more than or equal to 1000 DEG C, and mica paper 4 is pasted onto on oxygen rifle brick 1 by high temperature glue.Oxygen rifle brick 1 is in wedge shape, and oxygen rifle brick 1 is spliced by 7 blocks of refractory brick, and 7 blocks of refractory brick of oxygen rifle brick 1 are filled with mica paper 4 in gap each other.

The utility model well solves the adhesion between oxygen rifle brick, and oxygen rifle brick and oxygen rifle enclose adhesion between brick, to the destruction of enclosing brick and causing when removing oxygen rifle brick.

The utility model is between each refractory brick of oxygen rifle brick 1, oxygen rifle brick 1 and oxygen rifle enclose between brick 2 and add the thick special mica paper 4 of 0.2-0.5mm, because mica has the character of higher refractory temperature, refractory temperature >=1000 DEG C, itself material again with the difference of refractory brick, both can sealed oxygen rifle brick 1 each other, oxygen rifle brick 1 and oxygen rifle enclose gap between brick 2, by this medium by separated between brick and brick, finally can not be able to combine together again.When such dismounting, because every block brick is relatively independent, as long as dismantle one piece, other brick is just easy to remove, and it is smooth to remove back wall brick surrounding, repeatedly changes, and it is still intact to enclose brick brick face.

Concrete steps: 7 pieces of refractory brick removing surfaces of oxygen rifle brick 1 are clean, then 4 face high temperature glue of every block refractory brick brick are pasted upper mica paper 4, two faces vertically, termination are not pasted, and 7 pieces of refractory brick splicings are in wedge shape; The inner surface enclosing brick 2 at oxygen rifle also pastes mica paper 4; 7 pieces of refractory brick splicings of oxygen rifle brick 1 are loaded oxygen rifle in wedge shape by technical requirement enclose in brick 2.

Originally after loading oxygen rifle brick, oxygen rifle brick and oxygen rifle enclose brick and fuse into one in process of production, the adhesion of generation, after replacing oxygen rifle brick 2-3 time, oxygen rifle will be caused to enclose the out-of-flatness of the surface of internal cavity of brick, cause leakage, the economic loss at every turn caused several ten thousand and hundreds of thousands unit.And after adopting this technology, each cost more than 300 yuan that only increases, just better protecting oxygen rifle encloses brick, makes oxygen rifle enclose brick and brings up to about 3 years by 1.5 years service life, reduces cost more than 100 ten thousand yuan.
