What advantage does brick of magnalium pointed spar have?

Brick of magnalium pointed spar is the high quality fireproof data that is used at cement kiln, introduce brick of magnalium pointed spar to have what advantage for everybody today.


Chromium of special type magnalium is compound pointed spar brick is with magnalium chromium compound pointed spar and electric frit magnesia give priority to raw material, add a share special additive, use inorganic and compound bond, via scientific grading, puissant mix grind, 1000t grinds the machine that press a brick shapes, be more than agglomeration of kiln of channel of 1700 ℃ high temperature and into.
Magnalium is compound the performance dominant position of pointed spar brick (1) fight aggressivity goodly can (2) performance of good the skin that hang kiln (3) good heatproof shake performance (4) inferior thermal conductance
Brick of magnalium pointed spar has magnesia of what production technology (or pointed spar of aluminium of electric frit town is arenaceous) - broken smash - screening (fine grind - fine pink) - raw material - mix practice - figuration - dry - high temperature is firing - goods.
Magnesia of process of production of magnalium pointed spar and pointed spar of electric frit magnalium are arenaceous undertake defeating smashing by craft, make aggregate grain composition and fine pink fineness achieve craft requirement. Good preparation aggregate and fine pink ask to have metage burden strictly by craft, it is certain to join; is in li of bond mix grind 15 one 20 Min mixes inside machine, attrition pressing shapes on bricky machine, semi-manufactured goods classics 8 one 16 H is dry; Will dry inside kiln of good channel of adobe outfit person firing, high fever becomes temperature 1660 one 1680C.
Magnalium pointed spar does not bake bricks raw material is chosen intermediate agglomeration magnesia, beforehand small pink of complex magnalium pointed spar, silicon and alumina are small pink. Because do not bake bricks not riverside wants high temperature firing, the course is roast but immediate step is built use, because this is right the requirement of normal temperature intensity that does not bake bricks is stricter, place also wants to satisfy with bond: Have favorable combinative effect to be what basically comprise not to bake bricks with magnesia, despotic adobe should have enough strength giving a model, roast hind achieve intensity of normal temperature of 40 MPa above, contented carry, build by laying bricks or stones builds requirement; bond to facilitate use. Do not make produce craft to complication: The combinative function of bond should strong, join a quantity to want little, the high temperature capability that lest be reduced substantially,does not bake bricks.
Magnalium does not bake bricks introduction of commonly used bond is water glass solution a kind, use natrium of fluorine silicon acid to make stiffening agent; Another kind is to get together phosphate serves as bond, join a quantity to be in 0.8% one 1.0% when, the intensity of normal temperature compression after classics 200T X 24 H is handled has achieved result 80MPa; And when with water glass and fluorine silicon acid sodium mixed liquor makes bond, because add a capacity bigger. From theoretic say, can affect the high temperature capability of goods because of fetching and too much Na2O.
