Background technology
At present, the resistance to material of dry coke quenching cooling end uses B grades of mullite bricks (BM), service life about 4~5 years.This position
The height of the wearability of resistance to material, directly decides the length of service life.
Since Wuhan Iron and Steel Plant dry coke quenching in 2002, the country occurred in that substantial amounts of dry coke quenching engineering project.Dry coke quenching year in recent years
Checking maintenance situation, one of the problem of existing is that the dry room cooling end material that puts out has different degrees of abrasion, and mainly material is resistance to
Mill property difference causes abrasion overweight.Domestic dry coke quenching cooling end uses (Q) BM materials at present.Japanese dry coke quenching project, cooling end
Majority uses H31LL, also has and uses N53-M materials.Its index performance of the BM mullite bricks that cooling chamber is used at present is relatively low,
Mismatched with the performance indications required for actual bad working environments in coke dry quenching furnace, especially original BM mullite bricks are to normal temperature wearing coefficient
Less demanding, wherein normal temperature wear extent is<10cc index is too low, do not adapt to coke in coke dry quenching furnace rub for a long time generation mill
Damage, so causing cooling chamber brick large area wear damage.
The content of the invention
