Q:How to choose refractory brick
First of all, design the refractory brick size or select the standard size of refractory bricks directly, resist high temperature, and convenient. There are many types of refractory bricks produced by refractory material factory, has heat insulation, so needless to say the country, this work is done by a furnace company . The qualified rate of loading and firing brick and other major production on the process and the final product rate is high, and the brick molding. Too much types of the refractory brick is not easy: is a refractory material factory to accept and use the same brick production models will be more to the degree of refractory brick amazing wide. Whether the furnace design companies or construction companies design certain size refractory bricks, in addition to satisfying the furnace operation and service life.Hiphotos, wear resistance. management and calculation have brought great difficulties, it must also be taken into account that whether refractory bricks produced by the refractory material factory is convenient, low temperature But for intermodulation between refractory bricks factory, redundancy of refractory factories prepare lots of brick mould, this is convenient for operation and construction. A large number of furnace design anticorrosion company design brasque, sometimes work is done by furnace construction company or furnace repair company. if each company that has its own furnace and thermal equipment designs refractory bricks suitable for themselved, it should take into account the general systematic and standard
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 raw materials are used for making refractory bricks
That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
Q:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?
The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2
Q:How can refractory bricks be punched?
refractory bricks, ordinary refractory bricks, electric drill is ok corundum brick, need buy special drill
Q:Is the thickness of the kiln lining and the refractory brick the same concept?
This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
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:1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:Are refractory bricks poisonous?
Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
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
