High strength, low thermal conductivity High Alumina insulation firebrick for Kiln


Q: What is the heat preservation material used in a laboratory furnace?
Asbestos, high alumina brick, or carbonized silicon are often used.Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
Q: What refractory material does cupola lining use?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.
Q: What are the characteristics of high alumina bricks?
High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.
Q: What are the alloy wear resistance materials?
Alloy wear-resistant materials from different manufacturers different components in Beijing Naimo company as an example, the following alloy wear resistant material:1: Ni Cr alloy wear-resistant material2: chrome carbide wear-resistant material3: high manganese alloy wear-resistant material4: tungsten carbide alloy wear-resistant material5: nickel tungsten alloy wear-resistant material
Q: What are ordinary bricks, refractory bricks, hollow bricks?
Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
Q: How to test the aluminium bricks of high alumina refractory bricks?
Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
Q: What is the high temperature limit of refractory bricks and refractory soil?
Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
Q: What are the categories of bricks?
In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
