Gangue is fireproof material

Gangue is fireproof material, it is to show the firebrick that produces for main raw material by mineral separation or figuration of series of brick of firebrick heat preservation are fireproof material. Chooses gangue, may be to choose namely fasten other metal or metalloid when the waste residue of place remains, also include to make a living technically to produce fireproof material and make the handpick gangue that chooses the place after fastening to put forward further to gangue.

Groovy fireproof material, pledge for silicon by composition bisect fireproof material, siliceous aluminium pledges fireproof material, magnesium pledges fireproof material, siliceous magnesium pledges fireproof material, calcic magnesium pledges fireproof material and carbon pledge fireproof material. Its ask basically to be fireproof degree not under 1580 ℃ .

Silicon pledges the bases of fireproof material is SiO2, the content of the SiO2 in requirement raw material not under 94% .

Siliceous aluminous simple fireproof stuff, by different proportional Al2O3 and SiO2 composition, siO2 ≥ 85% , al2O3 ≤ 30% when, call; of half silica brick to upright when Al2O3 at 30%〜48% , call argillaceous brick; to become from Al2O3 ≥ 485 when, call tall aluminous brick.

Content of MgO of requirement of magnesian simple fireproof stuff not under 85% , among them, al2O3 does not get prep above 8% , weigh magnesia brick again.

Siliceous magnesium pledges fireproof material is comprised by MgO and SiO2, among them, siO2 does not get Zuo at 42% .

Can see from this, make the raw material of fireproof material, its comprise a system to basically be MgO-Al2O3-SiO2 system. De-carbon is qualitative outside fireproof material, the mineral photograph of all sorts of fireproof material and its are fireproof degree can get reflecting from phasor. Eliminate division of the brilliant at the beginning of cordierite outside chamfer of the occurrence low temperature around, inside the vast area of phasor, crystallization is mineral have extremely high fireproof temperature. This provided a whirly space to fireproof material raw material is searched in gangue.

In the bed of certain type, the country rock that accompanies an ox with ore or gangue are mineral, often have fire to become the composition basis of fireproof material, some even itself is good fireproof stuff namely. Be like as concomitant as photograph of mine of steatitic, asbestine magnesian stone of magnesite, water can use as; of simple fireproof stuff exceeds manufacturing magnesium base it is OK that the magnesian Gan in sexual cliff bed pulls stone, serpentine fire silicon acid is magnesian aluminous clay of Zuo of; of simple fireproof stuff, aluminous alumina, and the place in bed of certain and degenerative cliff is concomitant corundum, cyanite, sillimanite, andalusite, pyrophyllite, can not serve as high quality fireproof material via to calcine.

But, because fireproof data is average to raw material pure degree of demand is higher, the impurity of minim often can be brought about fireproof drop badly what spend. And regard mineral separation as residual gangue, often avoid the existence of foreign matter element very hard again, accordingly, produce fireproof material directly with gangue, still put in certain difficulty.

But ought to see at the same time, if be in,choose not other and mineral while, through increase or changing technological process, will be regarded as gangue so these are mineral try grading, extract, can use as fireproof material production. Although the likelihood raises cost of one part mineral separation such doing, but because do not need new mine,construction invests, do not need to build new to adopt a system, do not need to add any mineral separation equipment even, can obtain, accordingly, still have should try to take seriously.

For example: Jiangsu some asbestine mine, in exploitation asbestine while, companion is unripe collect a many serpentine, at first all regards flotsam as discard need not, already supplied Bao Gang as fireproof material raw material now.

In addition, in order to contain fireproof and mineral taller gangue makes aggregate or mix material, make up fireproof concrete, also be one uses way.
