Zhan Jiang where has firebrick to buy

Empty traffic of land of Zhan Jiang sea develops, it is another name for Guangdong Province mix on the west upper bay city group economic center, it is chinese mainland leads to the haven city with southeast Asia, Europe, Africa and Oceanian short range, zhan Jiang or seat of ministry of admiral of Chinese naval Nanhai. The whole nation approved one of 14 coastal and open cities 1984
With alumina - the brick of high-powered chromic corundum that oxidation chromium produces for main raw material, 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 is fought erode, fight a structure to flake, already obtained favorable use result in metallurgy, glass, carbon black, petro-chemical industry.

Chromic corundum brick
Wide already application is eroded at high temperature, high pressure, chemistry and the petrifaction with serious mechanical wear heats up corundum brick liner material is made in tool buy, produce technical progress as petrifaction industry, a lot of new technology and new technology were used in production, to make equipment achieves the goal of big negative charge, long cycle, feebleminded bad news, low cost, all sorts of pair of heat are returned to be versed in the liner material of equipment raised taller requirement outside dividing all sorts of pair of hot project facilities to undertake transforming. For this, developed a kind high temperature resistant with the product of chromic corundum series with fight aggressivity better, in order to satisfy the requirement of petrifaction industry.
The development of 1 goods reachs function target
Place of product of chromic corundum series 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. Performance of chromic corundum brick is superior, can reach the quality level of foreign congener product, in use can replace an entrance fireproof material.
2 function are analysed
The fireproof function of 2.1 firebrick
By Al2O3-Cr2O3 n duality phasor is knowable, al2O3 and Cr2O3 can fashion successive solid solution, and not low in all frit products is crude. Accordingly, in high pure Cr2O3 is joined in corundum material, add a capacity no matter how many, won't reduce the fireproof performance of material not only, make the fireproof function of material rises somewhat instead. Of chromic corundum brick fireproof degree (> 1790 ℃ ) reach loading bate temperature (> 1700 ℃ ) all excel is high pure corundum goods.
1790 ℃ ) reach loading bate temperature (> 1700 ℃ ) all excel is high pure corundum goods.
1700 ℃ ) all excel is high pure corundum goods.
The intensity of 2.2 firebrick
High pure the intensity of normal temperature compression of corundum brick is 70 ～ 100MPa commonly, the strength of normal temperature compression of brick of high-powered chromic corundum is general ＞ 150MPa. Its strength is apparent 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 fashioned between fine pink and fine pink, this solid solution joins grain, fine pink together like the bridge, make the intensity of material rises greatly.
Stability of 2.3 thermal shock
According to data report, cr2O3 is joined in corundum, it is 10% ～ when Cr2O3 content 66% when, the thermal shock stability of material is reduced along with the addition 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. The content of Cr2O3 of brick of high-powered chromic corundum that my factory promotion applies is between 12%~20% , the additive that stability of its thermal shock raises; to join a few generation to change especially somewhat than corundum brick and brick of the AKZ that production gives chromic corundum, thermal shock stability more actor.
2.4 fight broken bits to erode ability
Graph 1 be in for all sorts of fireproof material oxide melt is cindery medium solubility. By the graph 1 knowable, cr2O3 is fastened in coal aerification slag) the solubility in reaching all sorts of glass fuse-element wants than the solubility of other oxide material small much. Consequently Cr2O3 or the fireproof material that contain Cr2O3 are had fight aerification of broken bits of smelt of slag, coloured, coal goodly slag of slag, oily aerification and ability of all sorts of corrode of vitreous fuse-element frit. The fluid photograph viscosity that Cr2O3 fuse-element or Cr2O3 and slag reaction generate is compared other viscosity of low frit content is big, this prevented fine stoma of slaggy edge wool to be permeated to bricky system interior, avoid to form degenerative layer and produce a structure to flake.
Graph 2 show the chromic corundum brick that gave different Cr2O3 content and corundum brick by glass slaggy erodent deepness. When the experiment makes clear, ＜ of the Cr2O3 in the brick 17% when, content heals tall, glass is slaggy invasive deepness heals shallow.
To make clear further aerification furnace is slaggy to corundum brick and chromic corundum brick erode a circumstance, does the test fighting broken bits that uses aerification slag appearance to undertake below 1500 ℃ with crucible law make clear: ?  of Ji of locust of billabong Da ┍ shows slag of She qualitative? in all infiltration brick, permeate the surface along bricky interior stoma, the brick becomes Brown, have brick of chromic corundum of; of broken bits remain hardly scarcely by slaggy erode, broken bits and bricky surface do not have apparent chemical response, inside aperture brim and residual bounds are trenchant, broken bits to very few brick is permeated inside the brick the degenerative layer with thick 10mm of about 5 ～ is formed only all round aperture, a large number of slaggy remaining within crucible aperture.
Through: of theoretical analysis and practice proof? Dang of  of  of act of  of Ji of  of  of  of a legendary venomous insect of ┛ of drunk billabong Da is mellow  feeling jumps? of ┖ of Da of  sparrow billabong to fight a structure to flake the gender also compares corundum brick advantageous.
3 application
Use in steely industry, chromic corundum material pledges than corundum material service life lengthens one times above character, if steel bag breathes freely,the; such as the brick is used in coloured smelt industry, the wearability of chromic corundum brick and fight aggressivity other brick plants apparent excel; is in carbon black industry, brick of corundum of use chromium of carbon black factory compares Guangdong luxuriant name the corundum brick life that uses below same condition lengthens one times. Brick of the AK that this factory produces chromic corundum is used on the carbon black reaction furnace in factory of crimson county carbon black, service life already exceeded corundum brick.
In petro-chemical industry, inside furnace of aerification of plant of big, medium-sized fertilizer as a result of long-term high temperature (1450 ℃ of 1350 ～ ) , high pressure (3.1 ～ are 8.53MPa) , strong reducing atmosphere (CO+H2+CH4) and air current rate is old (make an appointment with 10m·s-1) , of fireproof to lining material erode, destroy more serious, demand of fireproof to lining material is so higher. Density of brick of high-powered chromic corundum is big, intensity is high, provide more than corundum brick fight air current to erode ability and wearability. Cr2O3 introduces to make the immanent quality of goods produces change in corundum brick, make of the brick fight slaggy erode reach impervious to appear a gender to rise significantly, chromic corundum brick is used to be able to improve the service life of aerification furnace on aerification furnace. Zhengzhou flourish fills factitive Central Plains to be able to bear or endure material character, pay attention to the amplification of oneself dimensions not only, more important is to stand in long-term development point of view from beginning to end, ceaseless development gives new-style fireproof data, satisfy more firm market demand ceaselessly thereby, comply with the development of tendency of the day. Major of flourish Cheng Naicai produces all sorts of tall aluminous bricks, firebrick, argillaceous brick, pouring the product such as makings, welcome broad client to come to a factory make an on-the-spot investigation on the spot, establish long cooperative relationship.
