Q:Can the fire clay to be reused?
Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q:What are the main constituents of refractory brick?
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon aluminum
Q:What are the specifications for brick?
In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
Q:Is the wall around the fire area using a firewall? What's the difference between a fireproof brick and a regular brick?
Fire bricks burn well!!In fact, the firewall does not necessarily have to use the so-called "fire brick", but to see the brick fire limit!240, the fire limit seems to be 4 hours, 370 I do not remember clearly, fire codes have, you see, do not think so naive!
Q:How can the silica in zircon sand be removed during the smelting of zirconium corundum?
Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
Q:Zirconium corundum 25 content or 40 content, how to distinguish in appearance?
Fused zirconia corundum brick is also called AZS AZS English is abbreviated to AZS, is based on three chemical composition of Al2O3 - Zr02 - Sio2 phase diagram of three component system, according to the content of the order, Al2O3 A, Zr02 Z, Sio2 S, national standards for the use of this abbreviation, such as No. 33 cast brick, abbreviated as AZS, 33#, No. 36 fused zirconium corundum brick, abbreviated as AZS, 36#, No. 41 fused zirconium corundum brick, abbreviated as AZS - 41#.
Q:What is brick power, half brick power and full brick power difference?
All brick power up to 500 watts up and down. The internal circuit is tight and heating, the device has good adhesion, the circuit is more advanced, and the efficiency is high, so it can achieve small size and high power.
Q:What are ordinary bricks, refractory brick, hollow bricks?
Material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size.
Q:What are kiln bricks?
Furnace (kiln; furnace; oven) is made of refractory material used for firing products; it is a necessary facility in the formation of ceramic art. Millions of years of human porcelain history, has accumulated rich experience and made kiln style. From the primitive society to open pile burn, burn up like digging to build Steamed Buns flame round kiln, half pour flame kiln, kiln, Banpo horseshoe shaped kiln to duck's egg, indoor gas kiln, kiln kiln electric current, in the continuous improvement in the development of science and technology.
Q:Just what is in the furnace material?
It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
