What are the classifications of magnesia chrome bricks
Magnesia chrome brick is composed of MgO55%80%, Cr2O38%20% partial alkali refractory thermal insulation materials crafts, with magnesia, compound spinel and a small amount of silicate phase. Compound spinel contains solid solutions of MgAl2O4, MgFe2O4, MgCr2O4 and FeAl2O4.
Magnesia chrome bricks in the 20th century after the 60 era because of the purity of raw materials and firing temperature to improve the rapid development trend, the current magnesia chrome bricks according to the different production methods can be divided into general bricks, immediate fusion bricks, mutual sintering bricks, refusion bricks and fused bricks.
(1) General magnesia-chrome brick
It is a traditional commodity, with chromium ore as coarse particulate matter and magnesia as fine powder. Or the two raw materials are composed of graded particles, and the firing temperature is generally 1550-1600 ° C. The microstructure of this kind of brick mainly shows that there is little immediate fusion between chromium ore particles and cubic magnesite, and more silicate (CMS) fine sand or crack protection. There is little dissolved phase in the cubic magnesite, very little immediate fusion in the cultivation medium, and this kind of brick has poor physical properties and poor slag corrosion resistance.
(2) Immediately fuse magnesia-chrome brick
Immediate fusion magnesia-chrome brick is in the general magnesia-chrome brick basic development trend, its production characteristics are key to two points, one is the selection of more pure raw materials, the second is the selection of higher firing temperature. In plain words, immediate fusion refers to the chromium ore particles in the brick and the cubic magnesite in the middle of more immediate contact, due to the raw material SiO2 less (manipulation in 1%25% below), the silicate generation is less, according to the high temperature firing method to make the silicate extrusion molding to the corner of the solid particles. This improves immediate solid phase fusion.
Immediate fusion magnesium-chrome brick because of the high level of immediate fusion, so that the brick has a high temperature compressive strength, slag resistance, corrosion resistance, erosion resistance, corrosion resistance and high-quality thermal shock reliability and volume reliability at 1800℃.
(3) mutually calcined magnesia-chrome bricks
The characteristics of this kind of handicraft production process is to burn the mixture of magnesia and chromium ore fine powder according to a certain preparation at high temperature, maintain the conversion into secondary spinel and magnesia-chromium ore immediate fusion for the purpose of solid phase reaction, prepare mutual calcined materials, and use this material to produce burnt products or organic chemical fusion crafts.
The immediate fusion and microstructure uniformity of intercalcined magnesia-chrome bricks are stronger than those of immediate fusion bricks, and there is a large amount of brucite dedissolved phase and intergranular secondary spinel. The intercalcined magnesia-chrome bricks have a series of stronger characteristics than immediate fusion bricks, especially famous for high temperature compressive strength, temperature resistance and slag resistance.
Mutual sintered bricks can be divided into two types, one is all mutual sintered bricks, particulate matter and fine powder new mutual calciners, whether fired or organic chemical fusion of their microstructure is mostly similar; The second is a part of the mutual sintering bricks, a part of the raw materials, such as coarse particles with mutual calcining materials, and a part of the fine powder can be mixed with fine chromium ore and magnesia paper powder according to a certain proportion of the brick, so that the fired and organic chemical fusion crafts will have a certain difference in microstructure.
(4) Re-fusion magnesia-chrome brick
Magnesia-chromium mixture particles are melted by electromelting tube method, and according to the crystallization of the solution, a raw material with a very symmetrical microstructure and composed of magnesia-chromium spinel and cubic magnesite mixed crystals as the key phase is produced. Such electromelting magnesia-chromium material is broken into a certain particle size distribution, mixed and formed, and fired to produce refused bricks, or immediately used as organic chemical junction bricks.
The microstructure of the refused brick is characterized by the immediate fusion of the aspect ratio and the presence of a lot of spinel dissolubilized phase: the base crystal with a lot of dissolubilized phase substantially changes the physical properties of the brucite, such as reducing the coefficient of linear expansion, improving the heat resistance, and improving the resistance to acid-alkali slag corrosion. The refused brick has similar characteristics to the actual application of fused cast brick, but has stronger temperature snap resistance and more symmetrical microstructure than fused cast brick.
The refused magnesium-chrome brick has a well-proportioned sand and gravel culture medium, and has fine cracks, and is more sensitive to sudden temperature changes than the fusion casting. The high temperature characteristics of handicrafts are close to the middle of fused cast bricks and immediately fused bricks.
(5) Cast magnesia-chrome brick
Magnesia and chromium mineral compounds are thoroughly melted in an electric arc furnace, and then the solution is forged into a fireproof casting mold. In the whole process of condensation, it is transformed into a smooth brucite and spinel crystal phase, and a fine crystal mechanism is produced, so the fused cast magnesia-chromium brick has excellent high temperature compressive strength and slag corrosion resistance.
Molten magnesium-chromium brick and electromolten magnesium-chromium material, with the height to width ratio of immediate fusion and with a lot of spinel dissolved phase, this kind of crafts caused by high relative density, slag is not easy to penetrate, so the slag resistance to improve the immediate fusion brick is stronger, but the heat resistance is worse than the two crafts.
In terms of the principle of relative ash infiltration of fused magnesia-chrome bricks, it has the advantage of being different, because it is a high-density frit made by melting, pouring, and overall water cooling, the slag only has the effect of erosion on the surface of the brick, and it is unlikely to penetrate (which has been confirmed by the cross-sectional assessment of the fused magnesia-chrome bricks after application). Therefore, although the production of fused magnesium-chromium bricks is difficult and expensive, the key parts of the non-ferrous plate smelting furnace in technical capitalist countries still retain the advantages and influence that other refractory insulation materials can not replace.
