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:Advantages and disadvantages of wall insulation system?
The advantages of internal insulation: insulation walls, paint inside the wall, and direct people or other biological contact, in order to ensure human or biological health in insulation coating insulation at the same time, we must first ensure that the paint is non-toxic, no volatile substances.
Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
Q:What refractory material does cupola lining use?
It's made of high quality refractory material: 1770 ~ 2000 centigrade.
Q:What's the difference between refractory bricks and insulating bricks?
As far as we are concerned about the characteristics of refractory bricks and thermal insulation bricks, refractory bricks are sure to be aimed at fire resistance, while insulating bricks are more focused on thermal insulation. And more specifically, let's take a look at the following parameters.
Q:Acid proof brick, acid resistant porcelain in the paste process with no seam
Acid resistant brick, acid resistant ceramic tile in the shop, many users only pay attention to beauty, and use not leave seam shop, or shop too tight, too close, easy to leave hidden dangers for the future.
Q:What materials are used for roof insulation
The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
The contrast between the two should not be much different, the insulation brick in the masonry wall at the same time, will be good insulation effect into the wall.
Q:The difference between clay bricks and clay bricks
Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.
Q:Are refractory bricks necessarily needed to build a kitchen stove?
The kitchen stove is used to cook dinner, so refractory bricks are unnecessarily needed. It depends on the temperature.
