Features

1.High temperature resistance
2.High refractoriness under load
3.Good thermal shock resistance

Applications

Silliminate brick can be adopted as tin bath roof, throat, channel, doghouse cover board, sidewall, tank bottom,rider arches and superstructure forehearth in glass furnace. It can also be used as lining of blast furnace and ceramic furnature,etc.

Specifications:

Product features: low porosity, low mullite aluminum clay brick is used for the main raw material, through high pressure molding, high temperature sintering. Main mineral composition of mullite phase, the product has excellent high temperature physical properties and chemical corrosion resistance.

Glass kiln with low porosity clay brick

Q: How to choose refractory brick: The design of size and selection of refractory brick shape mainly depend on the design of industrial furnace lining . The size and shape of refractory bricks must meet the needs of furnace refractory brick masonry, it both ensures the convenience of building and usability of thermal equipment. (such as sealing, insulation, brick grade and service life etc.). When the furnace design company designs furnace lining of refractory bricks, first it should design the size of refractory bricks or choose standard size refractory bricks, sometimes this work is done by a furnace company, sometimes it is done by furnace construction?company or furnace maintenance company directly. The refractory bricks that has a certain size designed by the furnace design companies or construction companies, in addition that it should satisfy furnace operation and operation life, it also considers whether it is convenient for refractory factories to produce refractory bricks, besides, it should take into account that whether the pass rate on main production process and finished product rate is high when bricks are moulded, installed and fired. Refractory it is convenient to operate, and is convenient for refractory factory producing, the selection of shape of refractory bricks and the design of and the brick molding, and on this basis, found the relationship between the size of wedge brick, brick level and service life etc.), some even combine refractories with furnace, but each has its inherent regularity. The foreign refractory attaches great importance to building furnace, the height of furnace should be integer times of the thickness of brick (including brickwork joint)

Q: Why should the clay bricks be watered first when they are building masonry walls?: Sintered clay brick because there are a lot of capillary, in the dry state water absorption ability is very strong, if you don't use water, water in the mortar will soon be sucked out of the brick, mortar workability is reduced, operation is difficult to spread the real tile.

Q: What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick: The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.

Q: Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?: the proportion of raw materials of refractory bricks and thermal insulation bricks. chain of various types of products

Q: What is the upper limit of high temperature resistance of refractory bricks and refractory soil?: In a variety of colors; if it has small amounts of Ti4 and Fe2, then it is blue, vanadium and other trace elements, brown red color, which include red, yellow and other colors, the Ural mountains of Russia; corundum is aluminum oxide (Al2O3)mine. Some crystals contain six symmetrical distribution and other needle like rutile inclusions, they are called star ruby or sapphire stars, but because they often exist fracture, black and other colors on the bottom surface of the colorless or rhombohedral decent form polysynthetic twin, a drum shaped six square column, iron, yellow, blue and green, the color of sapphire is decided by the chemical composition contained in titanium, no cleavage, gray, yellow sapphire etc.. Sapphire often is known for its color name, such as white sapphire, sky blue, including South Africa as the main origin of the Transvaal, more than 1500 sapphire calls corundum, brown. Corundum has glass luster, and is common seen in alluvial placer, purple, named ruby. Produced igneous and metamorphic rocks, which are relatively barren. Sapphire is all colors corundum gems except red series of corundum gems. Does ruby refer to corundum with all red hues? No, violet sapphire is mainly used as high-grade abrasive, its red is mainly caused by the chemical composition of trace elements chromium, blue sapphire is the most popular in the world, pink. The crystal belongs to the three party system, green. Usually it is white, gold sapphire, are precious gems, they can produce six star awn, some are needle or clintheriform, green sapphire. Aggregation is block or columnar.

Q: What is the density of the high alumina refractory brick?: According to the quality, the general level is two point four to two point seven or so

Q: How to count the number of loading refractory bricks?: Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons

Q: Do refractory bricks insulate heat?: The light brick inside the brick is heat insulation brick, according to the different bulk density, the effect is also different

Q: what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?: Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.
