What advantage does firebrick of brick of LZ-55 tall aluminium have?

1, fireproof degree: Of tall aluminous brick fireproof degree mix than argillaceous brick of half silica brick fireproof degree want tall, amount to 1750~1790 ℃ , belong to advanced and fireproof material.

2, loading bate temperature: Because high aluminous products is medium Al2O3 is tall, miscellaneous quality is little, the vitreous body that forms Yi Rong is little, loading bate temperature is so higher than argillaceous brick, but because of Molaishi crystallization did not form meshwork, temperature of reason loading bate still does not have silica brick tall.

3, the sex that fight broken bits: The Al2O3 in tall aluminous brick is more, adjacent at neuter and fireproof material, of can counteractive acid slag and basic slag erode, because contain SiO2 among them, the ability that fights basic slag so is some weaker than fighting the ability of acid slag.

4, basically use at build by laying bricks or stones to build liner of roof of blast furnace, hot-blast stove, electric stove, blast furnace, reverberator, rotary kiln. In addition, tall aluminous brick still uses brick of mouth of the head of a place of strategic importance that becomes checker brick of type of open-hearth furnace accumulation of heat, gating system to use, water to wait widely. But price of tall aluminous brick should compare argillaceous brick tall, reason can satisfy the place of the requirement to need not use tall aluminous brick with argillaceous brick.

5, the respect such as industry of course of study of ongoing grinding work, chemical industry and potter course of study also has saggar main use. Course of tall aluminous clay is in electric arc furnace melt, make abrade material, among them abrasive of electric frit corundum is a kind of abrasive that applies ** extensive at present, occupy the 2/3 of all abrasive product. Tall aluminous clay can produce all sorts of aluminous compound with a future life, if potassium sulfate is aluminium of vitriolic aluminium, hydroted alumina, chloridize, aluminous,wait for chemical product. In potter course of study, horniness clay and half horniness clay can regard pottery and porcelain of production daily expense, building as the raw material of porcelain and industrial porcelain.

6, tall aluminous clay still is used in wildcat, regard clean fossil oil as the used agent that prop up, hurried regards as fat dose on agriculture, and use as fight slippery, fight grind pave a road material, etc. Horniness clay still is used at making fireproof fiber of —— of new-style and fireproof heat insulating materials, it has high temperature resistant, coefficient of thermal conductivity small, acid-proof alkaline, sound-absorbing and wait for an advantage gently character, apply on the industry such as metallurgy, mechanical, electron, glass, pottery and porcelain extensive.
