- 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:What is the difference between fireclay bricks and high alumina refractory bricks?
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.
- Q:What materials are used for roof insulation?
- The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
- Q:What is the content of free silica in the refractory bricks of high alumina bricks?
- Refractory powders are not rich in free silica in varying degrees
- Q:How to reduce porosity of high alumina brick
- In order to reduce the porosity of high alumina brick, the corresponding measures should be taken from the selection of raw materials, batching, mixing, molding and firing.The water absorption rate of the first grade high alumina bauxite clinker should be less than 5%, and the water absorption rate of two grade high alumina material should be less than 7%. Fine grinding of soft clay and bauxite clinker with less than 4% water content. Mixed fine milling ingredients with this, can reduce the porosity of bricks.
- 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:Which is faster for heat transfer between corundum bricks and high alumina bricks?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
- Q:What are the requirements for Rubble backfill height?
- 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
- 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 is the price of the latest thermal insulation material?
- Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.
