Different (fireproof) the brick is the firebrick with a kind of complex external form, go up to sticking the different of qualitative, tall aluminous tribute firebrick, the scale 〔 of its over all dimension is the smallest of dimension and the largest size than) in 1:5Dimension of ply of; of limits less than is 4} one 95mm; well has not much man 2 reentrant (include reentrant of circular arc shape inside) , or have 5. , the acute angle of one 75‘ , or contain not the brick on the shadow that its quality of; of 4 over groove is 2 one 15kg and the tall aluminium qualitative firebrick of 2 one 18kg. To silicon qualitative different firebrick, the scale of its over all dimension (the smallest with the largest size than) be in] : 5; ply dimension is in limits 45- - 95mm; has not much}= 1 quadrilateral, or have a 5D“ the one acute angle of 750, or contain not is its quality of; of 2 over groove 2 one I? Kg. Qualitative to magnesium or for magnalium qualitative different firebrick, always was not listed the person is average model magnesium pledges or of magnalium qualitative firebrick all be labelled different firebrick.
Cent is axe firebrick big ax and small ax are to belong to perpendicular wedge firebrick. Big ax dimension: 230*114*65*55 (Mm) hatchet head dimension is: 230*114*65*45 (Mm) it is axe brick,
Of blade firebrick also is same cent for bolo mouth and little where a thing can be put to best use. Belong to then dimension of mouth of bolo of side wedge brick is: 230*114*65*55 (Mm) penknife mouth dimension is: 230*114*65*45(mm)
1, fireproof degree. Goods of tall aluminous brick is the high variety in products of siliceous aluminous simple fireproof data, its fireproof degree along with Al2O3, the addition of content and rise, general not under 1750—1790 ℃ . If Al2O3 content is more than the corundum brick of 95 ％ , fireproof degree can be as high as 1900-2000 ℃ .
2, loading bate temperature. The addition that the loading bate temperature of goods of tall aluminous brick follows 2 oxidation silicon and content of alkali metal oxide and reduce, but taller than argillaceous brick goods, it is 1420—1530 ℃ about. Al2O3. Content is more than the corundum brick of 95 ％ , temperature of its loading bate can amount to 1600 ℃ above.
3, the sex that fight broken bits. As a result of the 3 oxidation in goods of tall aluminous brick 2 aluminium are shown neuter and content is high, products of this kind of data is so basic to acid of slag erode all have counteractive capacity.
4, thermal shock stability. In goods of tall aluminous brick, when firebrick temperature changes, because expand,difference brings about stress concentration. So, the thermal shock stability that goods of tall aluminous brick compares argillaceous brick product is poor, general water-cooling frequency has 3—5 only second.
5, the heavy change that burn a line. If of goods of tall aluminous brick firing temperature is enough, firing time is enough, criterion volume is steady, the heavy change that burn a line is little; Conversely, if the remains of argillaceous brick goods is contractive,arise, the reason also is to produce recrystallization be caused by.
