Description
Technical field
The present invention relates to a kind of support, specifically, be a kind of using support as false angle-table bracket and its oblique in dry coke quenching
Using method in road bracket brick maintenance.
Background technology
In order to adapt to national energy saving and environmental protection requirement, most domestic steel mill and coke-oven plant is successively newly-built dry puts out
Burnt replacement wet quenching.According to we from domestic dry coke quenching from structure design, slope air course position is crucial, one side skew wind
Road supporting brick will bear top partition wall and the weight of ring air channel internal refractories（About 200t）, in production process body of heater partially in,
Slope air course supporting brick bears weight offset, discontinuity；On the other hand it is slope air course position refractory material work under bad environment,
It is subject to temperature fusion, rapid heat cycle for a long time, the impact such as air blast washes away, the friction of coke, chemical etching effect, thus lead to skew wind
The supporting brick fracture of road position, refractory material is impaired fastest, is the life-span bottleneck of whole coke dry quenching body refractory material, its longevity
Life is only more than about 1 year, and other position refractory life of coke dry quenching body about 8 years.Ask for slope air course bracket brick wear and rupture
Topic, at present, preferable repair method is to carry out safeguard protection with furred ceiling technical measures, to slope air course bracket windward side refractory brick
Removed, then again built by laying bricks or stones.Generally dry coke quenching chute bracket brick is destroyed seriously due to production process, typically needs every year
Want shutdown maintenance, the method for maintenance is to change damaged bracket brick.But furred ceiling technology installing engineering amount is big, installs, make steel
