Price of chromic corundum brick

The main and mineral composition of chromic corundum brick is α - Al2O3-Cr2O3 solid solution. Less important and mineral composition is a few compound pointed spar (or do not contain compound pointed spar) , oxidation chromic content is 1% ～ the firebrick of 30% . Have brick of corundum of brick of founding chromic corundum and agglomeration chromium two kinds. Usually chromic corundum brick points to brick of agglomeration chromic corundum namely. The particular case of price of chromic corundum brick should produce manufacturer to seek advice from a decision to fireproof material.

The chromic corundum brick that flourish Cheng Naicai produces a sale is with alumina - the brick of high-powered chromic corundum that oxidation chromium produces for main raw material, use special type technology of fireproof material production makes firebrick, can be improved and improve the immanent quality of goods, improve the high temperature capability of goods. Have fireproof degree of tall, intensity stability of big, thermal shock is good, fight erode the characteristic with strong capability, in using, be able to bear or endure erode, wear-resisting caustic, fight a structure to flake, already obtained favorable use result in metallurgy, glass, carbon black, petro-chemical industry. Place of chromic corundum brick uses raw material is deserve to compare by certain proportion by alumina and oxidation chromium, a kind of solid solution that becomes through chemical combination of high temperature frit. Use special type technology of fireproof material production makes firebrick, can be improved and improve the immanent quality of goods, improve the high temperature capability of goods.

Chromic content of oxidation of agglomeration chromium firm brick is common under brick of founding chromic corundum. Still can use slop pouring the law comes preparation, α - Al2O3 pink and oxidation chromic pink mix equably, add degumming agent and organic cohere agent to make thick stiff slop, join grog of partial chromic corundum at the same time, become adobe with the legal system that note an oar, again firing. Can use as brick of cover board of throat of the vitreous kiln liner, glass that pull silk and use at furnace of aerification of pressurization of oar of coal of incinerator of device of molten iron pretreatment, rubbish, water to carry line on the back to wait.

Current, chromic corundum brick had wider application, one kind is the chromic corundum brick that broken bits is main raw material to make and becomes with metallic chromium, this goods applies Yu Xin extensively smelt electric stove, volatilize on kiln, chromic corundum brick is having admirable heat brace up the function of stability and high temperature creep, accord with the requirement of national loop economy at the same time.

Another kind of firebrick that calls aluminous chromium pointed spar applies extensively on cupreous smelt, with one action broke the monopoly position of magnesian chromic brick.

   Chromic corundum brick has the following characteristics:

1, the fireproof function of goods, of chromic corundum brick fireproof degree (> 1790 ℃ ) reach loading bate temperature (> 1700 ℃ ) all excel is high pure corundum goods.

2, the intensity of goods, the strength of normal temperature compression of chromic corundum brick is general > 150MPa, its intensity is showing brick of prep above corundum. Because goods is in,this is firing in the process, between its grain and grain, between grain and fine pink, al2O3-Cr2O3 solid solution all was made between fine pink and fine pink, this solid solution is together connection of grain, fine pink like the bridge, make the strength of material greatly ongoing.

3, thermal shock stability, according to data report, cr2O3 is joined in corundum, when Cr2O3 content is 10%~66% , the thermal shock stability of material is reduced along with the accretion of Cr2O3 content, namely the chromic corundum brick with Cr2O3 low content, stability of its thermal shock is good at the chromic corundum brick with Cr2O3 high content.

4, fight broken bits to corrode ability strong.

Production of Cheng Naicai limited company sells Zhengzhou flourish fireproof stuff is old, old experience makes us more professional, if you have demand to chromic corundum brick, or it is to chromic corundum brick the price has doubt, greeting incoming telegram consults limited company of flourish Cheng Naicai, my company can provide high quality fireproof material and close service for you.
