Abstract
The invention discloses a method for pressing dry-quenching over-top bricks and relates to a dry quenching furnace which is used in coking production in the steel industry and a refractory brick pressing method. The over-top bricks are pressed in a vertical mode. In the method, by adopting a mode of pressing the over-top bricks up and down in the vertical direction, the uniformity of the volume density of upper and lower parts of brick bodies is guaranteed, volume impaction caused by thermal expansion in the circular direction is reduced, capacity of bearing upper pressure is improved, a circular elastic aftereffect is reduced, and the size of over-top brick combination is guaranteed.
Description
Technical field
The present invention relates to employed coke dry quenching furnace and refractory brick drawing method in a kind of steel industry coking production, refer to cross in a kind of coke dry quenching furnace the drawing method of dome brick particularly.
Background technology
Dry coke quenching technology is for the red burnt technology of traditional wet-treating, be to use inert gas the coke of red heat is cooled off and discharges coke at coke dry quenching furnace, after the heat exchange inert gas after first dedusting in boiler with the demineralized water heat exchange, produce steam, recycling process under the suction of final dusting at circulating fan.Dry coke quenching technology becomes the technology that clearly must adopt in the Chinese coking industry permit standard because it has advantages such as the energy of recovery, protection environment, raising coke quality.
Coke dry quenching furnace is dried to put out that the chamber is divided into cooling zone, chute district, annular passage district, the district prestores, the annular passage district is on top, chute district, be to rely on the support of chute bracket to form the passageway of forming by two sides refractory material masonry, send into disposable dust remover will cool off red heat coke inert gas afterwards, the interior walling gross weight in full annular air channel has surpassed 200 tons, cross dome brick by jack arch and be connected with the chute bracket, jack arch is crossed the basis that dome brick is exactly a walling in the full annular air channel.
Shown in Figure 1, jack arch is crossed dome brick combining structure 3 ' and is adopted six brick combinations to build by laying bricks or stones, bottom margin and bracket 2 ' are gone up planar horizontal, and the circumference stress that it is bearing the gravity pressure of upper, annular air channel interior wall and produced by thermal expansion caused the fracture of dome brick lower edge, comes off.Shown in Figure 2, had the dome brick compacting now and adopt horizontal drawing method, but its holding capacity is vertical that this has just reduced the holding capacity of crossing dome brick.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes existing dome brick drawing method, and a kind of drawing method that strengthened the dome brick bearing capacity is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of dry coke quenching is crossed the drawing method of dome brick, the described vertical drawing method of dome brick compacting employing of crossing.
Further, describedly vertically be compressed to up and down two-way compacting.
Drawing method of the present invention adopts the method for vertical pressurization up and down, thereby the bulk density at position is even about the assurance brick body, reduces the hoop direction and impacted by the volume of thermal expansion generation, increases the ability of bearing upper pressure, reduce the hoop elastic after effect, guaranteed the size of dome brick combination.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation that existing jack arch is crossed the dome brick combining structure;
Fig. 2 had dome brick drawing method schematic diagram now;
Fig. 3 is that the present invention crosses dome brick drawing method schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
As shown in Figure 3, a kind of dry coke quenching is crossed the drawing method of dome brick, adopts the vertical drawing method of twocouese up and down, can remedy that the die press stroke increases and the pressure that causes reduces, this can guarantee the brick body, and up and down the bulk density at position is even, thereby increases vertical holding capacity.Mould adopts movable die plate, can reduce clashing and breaking corner angle and depanning resistance.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. a dry coke quenching is crossed the drawing method of dome brick, it is characterized in that: describedly cross the dome brick compacting and adopt vertical drawing method.
