FAQ

Why limit sintering brick first and develop new wall material?

The sintering brick is not fit for the national energy saving policy. Indeed, to do a good job of energy saving and emission reduction, and protect our living environment, the relevant departments under the state issued a ban on the construction of the construction industry, prohibit the use of ordinary clay sintering.

Should prevent the rotary kiln from being damaged; why hang kiln coating on the rotary kiln; try to avoid the big knot; 5; maintain the integrity of flame shape; burn top fire; should be hung; to prolong the service life of the refractory brick; steel plate is unable to withstand the high temperature, strengthen calcination control; adjust the high temperature region; let the big block out in time; avoid burning the fire. . Preparation equipment manufacturers 4, find the correct operating parameters of rotary kiln according to the experience; often keep the temperature above 1450 DEG C in the container; what is the reason for the rotary kiln coating; and add a layer of strong protective layer on the surface; the cylinder of the rotary kiln cylinder is made of steel plate; this is only the first step to determine the safe operation of the rotary kiln; avoid damage or smash the rotary kiln coating. 2; measures should be taken to prevent the kiln coating fall off because of the stop of the kiln and the changing of sudden hotness and sudden cold; burn the top fire; raw materials of appropriate preparation ingredients . We need to know the the rotary kiln, make up in time. The fire resistance and thickness of refractory bricks are limited. 6; in the inside of the building with a layer of refractory brick. 8. Observe and adjust frequently; and can reduce the heat loss outward; control the fire; we take 8 steps to perfectly protect the rotary kiln: how to protect the kiln skin that is hung well; improve coal mouth structure; important operation method of long-term effective rate of safety energy-saving ball mill the work will be interrupted; deterioration, strengthen equipment maintenance of retary kiln, after hanging the rotary kiln skin; ensure clinker grain is fine and uniform; improve the thermal efficiency for the benefit of kiln skin sticking, must treat in time ;

refractory brick----is refractory material with a certain shape and size. According to the preparation process, bricks can be classified into burnt bricks, unburned brick, electric melting brick (fused cast brick) and the refractory insulating bricks; according to the shape and size, bricks can be classified into standard brick, ordinary brick and specific brick and etc. High-temperatured building material and structural material that can be used to build furnaces and various thermal equipments, and can endure various physical and chemical changes and mechanical effects at high temperature. For example, refractory clay brick, high alumina brick, cilica brick and magnesia brick and etc.. Fireclay -- usually refers to a kind of soil clay used for fire the stove and the furnace hearth in folk 1, characteristics and usages: Clay refractory brick is a kind of weak acid refractory material, its thermal stability is good, suitable for hot blast stove, various boiler lining, and flue, smoke room, etc.. 2, product specifications: Standard form, general profile, special shaped and special shaped brick. Physical and chemical properties of clay refractory bricks. The upper limit ---- about 1500 degrees under normal pressure

Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor

The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.

1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.

There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression

Why can't gravity retaining walls be made of clay bricks?

Gravity retaining walls are usually made of mortar stone, but no clay bricks are used.No, I don't know. It's possible to use clay bricks instead of clay bricks
