Blast furnace is the nucleus equipment producing molten iron in steel and iron industry, and its duty is high temperature, high pressure.Air blast is sent
Cold air after hot-blast stove is heated to 1000～1350 DEG C, continuously and stably enter State of Blast Furnace from air port through hot air duct
Cylinder, the coke before hot blast makes air port burns, and produces red-hot reproducibility coal gas.Visible, high-temperature hot-air is most important to blast furnace process.
Domestic in the last few years large blast furnace air supply duct systematic failures takes place frequently, and pipeline hot-spot, shell are rubescent, cracking runs wind, resistance to material
Caving in, blast furnace is forced damping down, blowing out is keeped in repair, and these problems greatly have impact on the properly functioning of blast furnace.Pipeline configuration
Whether design quality whether reasonable, inner lining material is qualified, and whether construction precision reaches requirement, directly affects blast furnace air-supply
The life-span of pipeline.
Practice have shown that, the junctions that the most flimsy position of hot air duct is just known as, current hot air duct three branches off
Mouthful design all be use modular tile structure, modular tile structure is the technology that China is introduced by nippon, continue to use always to
Modern.With raising, the increase of blast pressure of blast furnace air temperature, junctions Frequent Accidents, although taking a lot of improvement, but knot
Defect is still suffered from structure.Stress direction is inconsistent, uses at this position abnormity modular tile to build by laying bricks or stones, uses concave-concave between modular tile
Convex tenon groove structure is strengthened, to improve service life.Although this position material is strengthened, but junctions damaging problem is still
Happening occasionally, tracing it to its cause and be that modular tile is combined by one piece of one piece of brick, globality is poor.Before arm top masonry is undue
Stretching, reaching to be responsible for center, inner ring brick should bear the stress of own wt outer shroud also to be transmitted brick, so reduce inner ring
The overall stability of brick.This position becomes the weak spot of modular tile liner, adds the effect of gas shock, vibrations, destroys just
From the beginning of junctions top is at first, this is consistent with situation about occurring in actual production.
