Q:How to make refractory bricks and boiler wall adhesion more firm?
If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.
Q:Are there any differences between insulating bricks and refractory bricks?
The refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. density insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q:What is the standard size of high alumina brick?
The country has laid down a number of criteria for the use of refractory bricks to unify market demand.
Q:What are the high aluminum bricks made of?
The amount of refractory mud accounts for about 6% of the brick weight
Q:Can high alumina brick resist carburizing?
It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling
Q:What is the heat preservation material used in a laboratory furnace?
Thermal insulation cotton is a high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in the industrial furnace melting at high temperature, forming fluid. Then, compressed air is used to blow or use the wire throwing machine to turn the yarn into a fiber shape. After the cotton collector is collected, the cotton is formed into a heat preservation cotton.The high alumina brick is usually made of high alumina clinker with small amount of clay. After grinding, the high alumina brick is poured and shaped in the form of slurry by the way of gas generation or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
Q:Introduction of high alumina brick
Three alumina silicate refractory product with a content of two Al2O3 (48%).
Q:What is the difference between high alumina brick and clay brick?
Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
Q:What is the difference between metal compounds and metal solid solutions?
A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
Q:What are the grades of high alumina bricks?
According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.
