- Q: The difference between aluminium refractory and magnesia refractory
- Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
- Q: What is the density of a super high alumina brick and what is the price?
- Of course, the transaction price, please choose refractory brick manufacturer is better.
- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- High alumina brick:The mineral composition of the high alumina brick is determined by the bauxite used. The mineral composition of the clinker is usually mullite, corundum and glass. The theoretical composition of mullite is Al2O371.8%, SiO2 28.2%, and its melting decomposition temperature is 1840 DEG C. With acicular crystal, network cross structure, high temperature state showed better strength. Corundum in the form of alpha -Al2O3, melting point of 2050 degrees, hardness of Mohs 9, showing a granular and columnar crystal, has good chemical stability, acid, alkaline slag have a certain resistance. Based on the composition of mullite minerals, the phase composition of high alumina brick can be judged according to the content of Al2O3. When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase
- Q: What are the alloy wear resistance materials?
- KNMn19Cr2 (patent) high manganese alloy (ZGMn13Cr2MoRe), super high manganese alloy (ZGMn18Cr2MoRe); two: anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MOZCu); three: wear resistant alloy steel series: such as, low and high carbon multi metal combined steel (such as ZG40SiMnCrMO and ZG35Cr2MoNiRe); four: ADI (ADI) series; five: all kinds of composite or gradient material and hard alloy materials, nano KN alloy (patent product): such as chromium carbide composite (Cr2C3+Q235), high-energy ion osmosized tungsten carbide materials (WCSP), high toughness of cemented carbide (YK25.6), KN999 nano alloy (Beijing Naimo patent) etc.;
- Q: Corundum, high alumina and fireclay refractory difference is what
- In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
- Q: What is the apparent porosity of high alumina brick?
- In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
- Q: The difference between clay bricks and clay bricks
- According to the hole rate: solid brick (no hole or hole rate less than 25% bricks), porous brick (hole rate is equal to or greater than 25%), the size of the hole is small and the number of bricks, usually used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%, large pore size and small amount of brick, commonly used in non load parts, low strength grade).Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.
