Q:What kind of refractory brick is suitable for 24*28m rotary kiln of 5,000 tons?
24~28 meters belongs to the transitional zone, magnesia spinel brick or silicon carbide brick (Series)
Q:What are the differences and uses of non clay bricks, non clay bricks and ordinary red bricks?
Non clay brick clay brick walls can be completed, insulation and so on, often also can have some characteristics, such as light weight, heat insulation, heat absorbing ability better and so on.
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:Can mud and salt be used as refractory materials
Definitely not, the refractory temperature of soil just is more than 800 degrees, it belongs to eutectic mixture
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
Q:Do refractory bricks insulate heat?
It can not be generalized, generally, the insulation performance of clay is not good, but the hollow is good, such as light mullite bricks have good insulation. it depends on what kind of refractory brick
Q:What can be applied to the burned refractory brick to resist heat shock?
Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
Q:Can porous clay bricks be made of 12 walls to bear weight?
Porous brick using cement as binder, and sand, stone (aggregate) by adding water and mixing, molding and maintenance made with a plurality of rows of holes of the concrete products; after ordinary and lightweight aggregate concrete small hollow block and a variety of new wall materials.
Q:should clay or refractory cement be used to lay refractory bricks?
structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low
