- 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's the difference between a high aluminum brick and a clay brick, two?
- Light clay brick, refractory material is a kind of high porosity, low density, low thermal conductivity of refractory material, refractory materials called lightweight refractories, it includes insulating refractory products, refractory fiber and refractory fiber products. Heat insulation refractory material is characterized by high porosity, general 40%-85%, low volume density, lower than 1.5g/cm3, low thermal conductivity, generally lower than 1.0W (m.K). The utility model has the function of heat insulation of an industrial furnace, and can reduce the heat dissipation loss of the kiln, save energy, and can reduce the quality of the thermal engineering equipment. The mechanical strength, wear resistance and slag resistance of insulating refractory material are poor, and it is not suitable for the load-bearing structure of kiln and direct contact with slag, burden, molten metal and other parts.
- 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: 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%.
- Q: What are the ingredients of brick?
- Artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick. Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and. Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".
- Q: What is the sintering of non clay bricks?
- According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials.
- 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: 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: What are the differences between fired brick and clay brick?
- Clay brick is a kind of sintered brick, which is made of clay as raw material. Clay brick, ceramic tile and rock sheet brick also belong to sintered brick, so the range of sintered brick is wide.
- Q: How many bricks, mortar and how much wear and tear does one side of the clay brick masonry need?
- In the standard brick wall of 1M3, the standard brick occupies 516.53 pieces of *0.24M*0.12M*.053M=0.788M3
