- Q: The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
- The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
- 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: Why is the house made of refractory bricks not warm in winter
- Refractory bricks are not used in the house, but used in a large boiler inner
- Q: What is the use of refractory bricks
- Refractory bricks are mostly used as furnace lining in high temperature industry. Such as the iron and steel industry blast furnace, hot blast furnace, converter; colored reverberatory furnace
- Q: Is the waste of the fire resistant hazardous waste?
- it mainly depends on whether the refractory bricks contain chromium, if not, we only need to properly dispose of them, it would cost less and assure that there is no bad effect on people and the environment, shoot two hawks with one arrow; if there is hazardous elements like chromium and mercury, it may cost much and be disposed as industrial waste(or construction waste) by local environmental protection department, it is ok if there is a large amount of waste, because the environmental protection department will not take those waste that is not obviously dangerous seriously, even if it is dangerous waste. If there is no suitable manufacturers. It is better to look for a refractory brick manufacturers to recycle it, the cost is acceptable if the amount is small. In general, these heavy metal containing refractory bricks need to be disposed by the company that has quality to dispose such hazardous waste.
- Q: The boiler is divided into several categories according to the structure, what characteristics does each have?
- package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
- 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: The foundation is made of Mu10, which is new clay brick and M7.5 cement mortar. What does it mean?
- Clearly pointed out that bricks are MU10's new clay bricks, cement mortar gradation is M7.5, according to this ratio to configure the construction
- Q: can castable refractory replace refractory bricks in rotary?kiln?
- The heat produced in the welding process will cause local deformation of the rotary kiln, which will affect the dynamic balance, and the construction difficulty in the middle position of the rotary kiln is much larger than that of the refractory bricks. Moreover, the construction quality is not easy to ensure, generally only replace the refractory brick in the kilneye, because the construction of the castable refractory need to weld the anchor
- Q: Do refractory bricks resist corrosion and sulfur?
- There are anticorrosion and acid proof refractory bricks
