Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
Q:The difference between light high alumina brick and heavy aluminum brick
High aluminum brick is one of the ideal heat insulating material, with high strength, low thermal conductivity, good insulation performance, low price and other characteristics, has been widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall, it is also used in various heating furnace coking furnace of iron and steel industry and other thermal equipment heat treatment, lining material, and has broad market prospects.
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:In 2016, a few of the traditional refractory materials will be able to survive
In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.
Q:Corundum, high alumina and fireclay refractory difference is what
Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.
Q:What refractory material does cupola lining use?
A class of inorganic nonmetallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.
Q:How are the high alumina bricks fired?
Generally, the high alumina bauxite is added with a small amount of clay. After being ground, the gas is injected and shaped in the form of slurry by the way of gas attack or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used to replace part of bauxite clinker. Used for lining and thermal insulation of masonry kilns, as well as for areas where there is no high temperature, high melting material erosion and erosion effects. When touching the flame directly, the touch temperature shall not be higher than 1350 degrees.
Q:What are the high aluminum bricks made of?
We specialize in the production of various LeiBao refractory refractory material, such as corundum, zirconia products, alumina hollow ball products, mullite products and so on.
Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?
Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.
