The color of firebrick is the color decision that constitutes material by it, maize firebrick product is argillaceous brick product more, the product with inferior content of the alumina in tall aluminous brick. Now, let us understand the brick of low creep clay with the dinkum color in maize firebrick.
Want to understand brick of low creep clay, we should clear up argillaceous brick first, it is with clay (include the pink such as shaly, gangue to expect) for main raw material, classics pug processing, shape, dry become with roast, have sincere and part hollowly.
Brick of low creep clay is with frit of fancy Jiao Baoshi, andalusite, report Molaishi is main raw material, join a few additive.
We match in raw material 3 class burden is used in comparing, in all the craft such as mill pink, can develop a porosity to be 13 ～ 15% , creep rate is 05 ～ 08% , temperature of 02Mpa loading bate is 1472 ℃ , intensity of normal temperature compression is the brick of high quality clay of 100MPa.
Manage of brick of low creep clay changes target:
Brick of low creep clay leads experiment temperature cent to wait for 3 brands for DRN-125, DRN-120, DRN-115 according to creep.
The name from it can see, this clay brick has soft character of better low creep and tall carry on one's shoulder.
In the meantime, a kind when regard clay as the brick, it can use local materials, low-cost, wear well, still have pretty good fireproof sex, adiabatic, sound insulation, suck the advantage such as tide.
Accordingly, brick of low creep clay is used extensively at metallurgy, building materials, chemical industry, oil, machinery to make, the industrial domain such as silicate, motivation, use generally on hot-blast stove.
Compare with photograph of brick of low creep clay, the color of brick of 3 class tall aluminium is deeper on maize administrative levels one pace, increase of content ceaselessly as alumina, the color of tall aluminous brick will tend nigger-brown, the fireproof performance that also represented it is more good.
