Q:Why should the clay bricks be watered first when they are building masonry walls?

Therefore, in order to facilitate the operation, so that the mortar has a suitable hardening and strength growth environment, to ensure the quality of masonry, bricks must be watered before use wet.

Q:How to repair the boiler?

What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick

Q:does furnace use refractory cement to make refractory bricks?

You can use fireclay, refractory cement is commonly used to arch. fireclay has good viscidity, it is handy to use.

Q:The application of wasted refractory bricks

Refine waste copper, and waste refractory bricks can be used again, shoot two hawks with one arrow

Q:Can lime rotary kiln refractory brick kiln be hung with klin coating?

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 ;

Q:Development prospect of refractory bricks

Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.

Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.

Dark red? Bright red? Orange red? 400,1100 or 1500 probably

Q:Lining of refractory bricks in rotary furnace

About 7000~10000 furnace in steelmaking, the level of maintenance and management of each plant is different! Refractory thinning relates to safety issues (equipment and people safety). i am not clear about zinc smelting! Zinc smelting may use rotary kiln! blow the zinc powder into the kiln.

Q:What is the size of mechanism brick and general refractory brick?

The ordinary refractory brick is 230mm long, 53mm thick; red brick is 240mm long, 115mm wide, 65mm thick,

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.
