Description
Technical field
The present invention relates to a kind of coking industry coke oven technical fields, definitely belong to a kind of answering for coke oven regenerator checker brick
Close masonry construction.
Background technology
7.63m coke ovens are the especially big volumes of Recuperative heat type that the heat stepwise of German Wood Company exploitation is combined with waste gas circulation
Coke oven produces 2130000 t/a of dry full coke per year, and technique is provided by Wood company, and Zhong Yejiaonai companies carry out transfer design.1 7.63m
The various refractory materials of coke oven up to 30,000 t, up to more than 1100 plant by special form brick, according to the different operating modes at each position of coke oven, selects silicon respectively
The refractory material laying of the types such as brick, semi-silica brick, clay brick, high-alumina insulated brick, sillimanite brick, common brick and castable.In Wood
In the Basic Design of company, 7.63m coke oven Main Refractories use German Standard (DIN standards), the conversion of Zhong Yejiaonai companies
If the index of silica brick, semi-silica brick is increased a bulk density by timing reference Chinese Industrial Standards (CIS).Refractory material is wide in variety, of large quantities
And if each refractory material has many index controls bad, can influence service life and the normal operation of coke oven again.The use of coke oven
Service life, some were up to 30 years or more, and regenerative chamber is mostly clay brick and semi-silica brick with refractory material, less with rear performance study.
Wuhan Iron and Steel Plant company possesses 7.63m large capacity coke ovens 2,7m coke ovens 2,6m coke ovens 5, coke annual production capacity 624
Ten thousand tons.Two 7.63 m capacity coke ovens technologies are introduced from Germany, are gone into operation respectively in March, 2008, June.Regenerative chamber uses lattice
Formula designs, and air and coal gas are adjusted by regenerative chamber lower part jet tray.After going into operation 5 years, 7.63 m coke ovens part carbonization chambers
Coke wilfully（It is generally called low temperature number）, cause to generate a large amount of black flue dust when coke pushing, while finding basement portion Pan Chu
Gas leakage severely exceeds.In 7.63m coke oven processs of construction, regenerative chamber uses the clay of Henan D refractory Companies production
The semi-silica brick of checker brick and the production of Henan J refractory Companies, there are problem, regenerator lattice bricks deformation, melting loss occurs for quality.
To find out its cause, the quality with refractory material is related, it is also related with technological parameter with the production technology characteristic of 7.63m coke ovens.
Coke oven regenerator checker brick generally use clay brick；Some producers are to reduce cost using waste material even three-level alumina
The main material flint clay of quartz substitution clay brick is added.So that when coke oven BF gas heating, regenerative chamber top checker brick exist
It is corroded by sour gas under reducing atmosphere, generates swell.Regenerative chamber top checker brick mostly use low aluminium clay checker brick；Lower part
With the clay brick of AW-2, alumina content is close to 40%, but in Wuhan Iron and Steel Plant 10#、9#It is found in the investigation on the spot of coke oven：Top clay
There is melting loss in checker brick and foaming deforms.Clay checker brick bulk density 2.32g/cm used in Wuhan Iron and Steel Plant3, alumina content
48.85%, it is desirable that bulk density is not less than 2.1g/cm3, alumina content is not less than 40%.
Semi-silica brick refers to SiO2Content be more than 65% alumina-silica refractory product, generally with containing quartz sand fire clay,
Pyrophyllite and fire clay or the tailing of kaolin ore dressing make raw material.Dilatancy after semi-silica brick is heated is less big, this
Micro expansion speciality is conducive to improve the globality of masonry.Semi-silica brick can weaken slag to masonry corrode, when high-temperature slag with
Generates the larger enamel-like substance of one layer of viscosity on the surface of brick after the contact of brick surface, slag can be prevented to continue to permeate into brick, shape
At layer protective layer, to improve the corrosion resistance of brick.Semi-silica brick is for coke oven regenerator middle and lower part using semi-silica brick
Purpose is tightness in order to ensure masonry and prevents sour gas from corroding (when BF gas heating).The thermal expansion of semi-silica brick
Between clay brick and silica brick, pyrophyllite dosage needs stringent control with firing temperature in dispensing, to ensure physical and chemical index
Reach requirement.The country produces the lack of material of semi-silica brick since pyrophillite raw material resources are limited, and part of the manufacturer is quartzy using being added
The ingredient of the raw material adjustment semi-silica brick of equal silicon oxide-containings, but its performance is affected, and is susceptible to the problem of deforming melting loss.
Half silicon checker brick bulk density 2.05-2.15g/cm used in Wuhan Iron and Steel Plant3, alumina content 48.85%.
Coke oven regenerator checker brick using clay checker brick and semi-silica brick are compound build by laying bricks or stones by the way of, such as 4 layers of bottom clay
Checker brick, 6 layer half of middle part silicon checker brick, 6 layers of top clay checker brick.Such structure has problems in that if top coal
Gas is tempered or leakage, and temperature could possibly be higher than 1300 DEG C or even to 1400 DEG C, at this moment, the loading softening temperature of common clay checker brick
Degree require be only deformation 0.6% when be not less than 1450 DEG C, 40 DEG C of error range, a coke oven maximum life span at 30 years or more, this
The heat exchange for influencing air-flow at the top of sample after checker brick deformation, is finally easily deformed blocking stomata, and it is relatively low temperature occur, influences coke oven
Coking time and coking temperature, wilfully, coke pushing over-emitting black exhaust produces impacted coke.
Through retrieval
Blast furnace leck brick (CN201510649925.3) patent of invention includes matrix, including the base at center and is set
It is placed in the compacted zone of base upper surface, base lower surface is provided with heat insulating porous layer, and heat insulating porous layer thickness is the 1/3 of base,
Dense layer thickness is the 1/5 of base, and substrate surface is evenly equipped with the blind hole that aperture is 10mm ~ 15mm, water has been poured in blind hole
Material-mud.High pressure-temperature is molded, firm in structure, of low cost, high temperature resistant, and thermal stability is good.The document is only glutinous from effect
The technical measures that the structure of cob brick is taken, but it prepares the complex process of brick, and the structure of brick is also relative complex.
A kind of low aluminium checker brick of coke oven and production technology (CN201610883974.8) patent of invention disclose a kind of coke
The low aluminium checker brick of stove and production technology.The low aluminium checker brick of the coke oven are by mass percentage at being grouped as：Semisoft clay
30%, flint clay 55%, fire-clay grog 15%, additional organic bond lignosulfite 2%.The grid of the present invention
Brick is low aluminum products, and low aluminum products are half acid refractory products, at high operating temperatures volume stability, and alkali resistance atmosphere capability is strong,
And load softening point is high, improves applied at elevated temperature intensity, it is more suitable for coke furnace carbonization chamber bottom, regenerative chamber, double-edged fine-toothed comb brick；Using
The New Type Material can extend the service life of checker brick, smoothly ensure the normal heat exchange of coke oven, be provided with for coking production stabilization
Effect ground ensures support.The document is also the problem existing for the brick from solution, is asked from the solution of the structure of regenerative chamber
Topic.
Invention content
The invention reside in the shortcomings of the prior art is overcome, a kind of used by coke oven regenerator checker brick is provided and shows gas
