Saddle steel took the lead in using much brilliant Mo Laishi in area of burner of complete hydrogen bell furnace fireproof fiber vacuum shapes compound brick. Although heat insulation and bulk density problem were solved in burner area. Its service life appears mostly after a year horniness piece clearance increases, craze falls off. Much brilliant Mo Laishi is fireproof fiber vacuum shapes the compound brick blaze gas to 80 ~100m/s of burner of complete hydrogen bell furnace erodes, fall via heat for a long time and eroding although,be out of shape big.
Be not area of burner of prep above of burner area service life, basically be the temperature that exports with burner brick inside burner brick taller, be in commonly 1200 -1260 ℃ , heat cover burner is decorated for tangential enter, so high temperature blaze is added in the high speed on burner area wall to rotate after gas is ejective, accordingly, the wall temperature prep above of burner area is not burner area:
(1) because outclass of burner area temperature is fireproof fiber crystallization temperature, contractive rate is rapid, cause stress big, aperture craze increases between fiber brick, if the brick seams brick of fiber of pottery and porcelain of intensity prep above, will cause fireproof fiber piece oneself craze, such integral sexes are destroyed, fall off very easily and damaged.
(Exterior density and hardness are more than brick of 2) fireproof fiber in-house, once craze, air current of high temperature high speed is formed erode the damaged that also quickened fireproof fiber brick and be out of shape.
(3) relies on annular build by laying bricks or stones to build outer fish trap as a result of oneself of fireproof fiber brick inside, once craze of annular whole sex is destroyed, its are aseismatic the gender is reduced greatly.
(4) much brilliant is fireproof fiber is fiber of condition of glass of a kind of blame, its a few crystallization temperature are very high, systole is very small, but in because mix,matching (3:7) have 70% tall aluminium fireproof fiber systole is bigger, if be pure crystal,its systole is less than fireproof fiber brick far mix match fireproof fiber and tall aluminous fireproof fiber, but still put in integral sex to differ problem „
Heating as a result of fireproof fiber is a kind of not reversible systole in the process: Say so, this needs the problem that the one-time construction that it is not get sth done once and for ever can solve to heat according to fiber in existing installation method time, after fireproof fiber systole is stabilized basically, want to undertake 2 times handling, the aperture that forms in fireproof fiber brick is useful after high temperature puddle and fireproof fine vinylon and cotton blend mix, a place of strategic importance takes crack in, form union 2 times. Such, service life can rise. But undertake processing does not agree with again 2 times successional production. Current, a few manufacturer are solve life problem, entered an error, in a few kinds of experiments, although one-time investment is little, but service life more not ideal.
