Application:
High alumina brick is widely used for Widely used in blast furnaces, Hot Blast Stove,Steel ladle lining, Reheating furnace, Cement kiln,Tunnel kiln,boiler, coke oven, carbon furnace,glass kiln , Steel smelting furnace and various kiln lining and thermotechnical equipment, 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:What's the price of high alumina refractory bricks?
- Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.
- Q:In 2016, a few of the traditional refractory materials will be able to survive
- From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;
- Q:How to reduce porosity of high alumina brick
- When proportioning, the ratio of coarse to medium to fine is 4:2:4, and the maximum particle size should be no more than 5mm. The mixing order is as follows: first adding coarse particles, then adding sulfite pulp waste liquid, premixed 3min, then adding high aluminum fine powder for mixing. The operation process is coarse and fine particles added in sulfuric acid with crushed pulp waste.In order to reduce the porosity, our company suggested that the single-sided pressure changed to double-sided pressure instead of double-sided pressure, the number of strikes should also vary according to the amount of feeding. If the kiln is fired, the location of the fire hole shall be adjusted so that the middle part is dense, the edge is thin, and the door near the kiln is properly encrypted so that the temperature difference between the furnace top and bottom and the temperature difference between the inside and outside are not greater than 20 degrees.
- 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: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 refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- Q:Introduction of high alumina brick
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not identical. For example, European countries limit the content of Al2O3 to high alumina refractories by 42%. In China, the content of Al2O3 in high alumina brick is usually divided into three parts: I, etc. - Al2O3 content, >75%, II, etc. - Al2O3 content is 60 ~ 75%, and the content of Al2O3 is 48 ~ 60%.
- Q:What are the common thermal insulation materials for thermal conductivity?
- The single organic insulation material should be the best polyurethane in the field. In accordance with the production process can be divided into on-site foam polyurethane and factory prefabricated rigid foam polyurethane board. The scene is polyurethane foam isocyanate and polyol to cool (polyether or polyester) two components as the main raw materials with additives, the on-site spraying construction with thermal insulation and waterproof function of the rigid foam material.
- Q:How many cubic bricks does a high alumina brick have?
- Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.
