Firebrick of Mo Laishi series manufactures technology

Mo Laishi pledges fireproof material divides agglomeration Mo Laishi brick and Mo Laishi of electric frit pipe fitting brick 2 kinds.

1, low creep Mo Laishi brick

In order to make tall aluminium of grog of Mo Laishi cement, special grade aluminous cement grog is raw material, another adds calcite of one part tall purity and antiseptic, producible make low creep Mo Laishi brick.

Raw material comes via smashing after 3mm of particle size distribution, via dividing iron equipment, residue on sieve reserve is used. Does raw material secret recipe give out: ? ?4% of N of handkerchief of  word  , grog of Ji earth cement 20% , calcite 6% , grind in all pulverize 40% . Raw material is in mix grind begin in machine mix practice. Add grain makings first, dry 3min of shirt-sleeve agent mix up is added after mixing 1min, add fine pink again. Always mix practice be between 10? 12min. 24h of the classics after pug mixes practice expects tiredly, pug water portion with 5? 7% advisable. Pug particle size distribution is formed give out: ≫3mm, 5%;3? 1mm, 35~40%;1? 0.5mm, 5? 10%;0.5? 0.1mm, 6? 10%;0.1mm, > 40% .

3mm, 5%;3? 1mm, 35~40%;1? 0.5mm, 5? 10%;0.5? 0.1mm, 6? 10%;0.1mm, > 40% .

Figuration grinds in 300t begin on the machine that press a brick. The cubage of base substrate should operate relative to density control in 2.70g/cm3. Is base substrate in 50? 110 ℃ issue dry rash, do the 16h between impetuous . Do portion of water of remain of the base substrate after impetuous to answer under 0.5% . The of * tall fire of handicraft is spent for 1600 ℃ , 16h of adiabatic heat preservation. The physics index value of handicraft gives out: Show hole to lead 19? Is 21%; cubage opposite density 2.55? Compressive strength of 2.60g/cm3; compression experiment 69? 116MPa;1450°C, 50h pressing creep is led 0.12% .

2, low creep agglomeration Mo Laishi brick

Make stone with andalusite, among silicon line Shi Zunzheng grain content, what pink of silicon line stone, aluminous pink, industry produces alumina pink, clay noodles or vermicelli made from bean or sweet potato starch is mutual fine grind pulverize is made help advance somebody's career matrix makings can make agglomeration Mo Laishi brick. Its raw material makes up give out: Stone: content of the grain intermediate: Fine pink =50:12:38. Add in condiment compound model shirt-sleeve agent, grind with 260t figuration of the machine that press a brick. Airing of base substrate classics comes rudimental water portion under 1% , fire is begun in installing blaze kiln. Fire is spent for 1490 ℃ , 19h of adiabatic heat preservation, the hole rate of handicraft is achieved 17.15% , cubage is opposite density 2.53g/cm3, normal temperature issues 136.5MPa of compression experiment compressive strength, load molten spends 1627 ℃ . 1450 ℃ , 50h creep rate is achieved 0.87% . If fire is spent,be 1450 ℃ , heat insolation increases to 26h between heat preservation , return the eye land that can exceed agglomeration.
