Muffle furnace not comes with corundum stone brick

Muffle furnace has a variety of kinds, furnace of muffle furnace soaking is a kind of commonner furnace model, introduce soaking muffle furnace to use corundum for everybody today Mo Laishi brick, hope to be helped somewhat to everybody.
　　
Muffle furnace uses fireproof data
Furnace of high temperature soaking is make friends factory is used at heating to be versed in with the heat of soaking steel ingot first equipment, liner uses a variety of fireproof data, include fireproof and firebrick, pouring makings, material has Mo Laishi of tall aluminium, clay, corundum, magnesium character silicon is qualitative, qualitative etc, body of heater comprises by hearth, boiler setting and furnace lid, show square or rectangle, also call furnace hole.
　　
Mo Laishi brick applies corundum
Muffle furnace not comes with corundum stone brick is the fireproof data that is used at the place such as mouth, this product uses corundum, Molaishi to be main raw material, exceed fine pink and additive through adding silicon of right amount alumina, oxidation, high temperature fire finishs in oxidation atmosphere and become. Mo Laishi brick can contact corundum directly blaze, fight flake, high temperature resistant, can regard high temperature industry as the adiabatic line of furnace already, also can regard the job of furnace of kiln of other industry high temperature as the layer, basically apply at petrifaction industry, large and medium-sized furnace of synthetic ammonia aerification and stove of magnetic material gas use data, material of establishment of form a complete set of furnace of kiln of high temperature industry.
　　
Product introduction
This product collects in order to to synthesize Molaishi and jade of electric frit Baigang to be raw material artificially, it is bond with Suzhou earth, can make mouth of electric roof, electric stove use Molaishi corundum brick.
　　
Mo Laishi of will artificial synthesis is broken to be less than be equal to 4mm to make aggregate, electric frit white corundum is ground to be less than be equal to 0.074mm to make fine noodles or vermicelli made from bean or sweet potato starch, the vibration of Suzhou earth classics after stoving grinds mill to be less than character be equal to 0.5mm to make bond. Burden scale limits is as follows: Synthesize Mo Laishi 55~65% , 25~30% of electric frit white corundum, suzhou earth 8~10% . Batch is used wet grind machine mix.
　　
Grain makings is added first when mixing refine, mix refine 1~2min, join bond to mix refine 2~3min next, fine pink is joined to mix refine 3~5min after, always mix left and right sides of refine time 10min. Its grain comprises as follows: Be more than be equal to 2mm17.9~20.2% , 2~1mm14.3%~18.7% , 1~0.5mm3.9~5.8% , 0.5-0.1mm13.1~15.9% , be less than be equal to 0.1mm41.3~44.7% , water divides 4.6~5.4% .
　　
Embryo body presses bricky machine to shape with 300t attrition, base substrate density is 2.70g/cm3. Embryo body undertakes inside channel desiccator dry. ℃ of entrance temperature 40~50, temperature of senior officer dry 130 ℃ , dry time 48h, embryo form moisture content is more than 1.5% . Goods is firing inside channel kiln, firing temperature is 1550 ℃ , 10h of heat preservation time.
　　
　　
Corundum not comes index of stone brick function: Al2O3: 73.06% , siO2: 24.10% , apparent pore is led 19.9% , bulk density 2.55g/cm3, 81.7MPa of intensity of normal temperature compression, 1550 ℃ , the heavy change that burn a line leads 3h - 0.11% , loading bate begins temperature 1710 ℃ .
　　
Muffle furnace not comes with corundum stone brick cent is electric frit goods and agglomeration goods, two kinds of prices differ bigger, want to choose appropriate firebrick according to using a requirement.
