Q:Is the waste of the fire resistant hazardous waste?
Can be recycled and reused.
Q:What are the properties of clay bricks?
Clay brick is very important. It can make clay brick not only with high refractoriness, but also can be used in many high temperature thermal equipment. The brick brick has better resistance to hot and cold, and the water cooling can reach 10~25 times at 850 centigrade. Clay brick can resist weak acid slag corrosion, the resistance to alkaline slag is slightly worse, increasing the content of Al2O3, can improve the ability of alkali resistance slag.
Q:What mud is the refractory brick made of?
The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.
Q:th choose of different refractory bricks in the rotary kiln
According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
Q:Where the refractory bricks rider bricks that are used for building arch and vault should be put?
Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
Q:refractory bricks of fireclay
According to the preparation process, it can be divided into bricks, high alumina brick, magnesia brickand so on, such as refractory clay brick, and ordinary brick; according to the shape and size, it can be divided into standard brick and silica brick, it can withstand all kinds of physical and chemical changes and mechanical action at high temperature; silica brick can be used as high-temperature building materials and structural material to build kiln and kinds of thermal equipments. Refractory material and fused brick with a certain shape and size are called refractory brick for short.
Q:What is the difference between fused brick and clay brick?
Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks. 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:How to built refractory bricks as fitting between square and circle ducts
Use rectangle at the bottom and knife type for the top. trapezoid for junction.
Q:What can be applied to the burned refractory brick to resist heat shock?
Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
Q:Expansion ratio of light corundum fireproofing brick
And then the appropriate drying, the using temperature 1500~1700 degrees of light corundum brick, the porosity is 70% to 80% Now, use foaming method to produce light corundum brick, 3g/, shaped idiosome with mould dry for 4 days in 60 degree to 70 degree oast, it will demoulding, foaming method and evaporating method produce light corundum brick, the thermal conductivity is 0. the containing of AL203 has difference, the corundum brick that use corundum hollow sphere to produce contain the highest AL203 Finished light corundum brick don't have accurate shape and size after firing.8 1, so products need mechanical or manual cutting after the kiln, finally, firing in 1300 degree and 1550 degree, basically still meters with water forming, just add to burn: 50~60h, because its production methods and the introduction of additives are different, the total sintering time.17W/, light corundum fireproofing brick can be made into density is 0, withstand voltage strength is 4MPa, the containing of A1203 is no more than 99%.
