Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.
Q:How much is one ton of high alumina refractory brick?
Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.
Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
Q:Is glass wool inorganic thermal insulation material?
Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.
Q:The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
Lining 1 yuan to prevent direct damage to the Sindh kiln high temperature flame or air, to protect the kiln carcass; 2, to prevent harmful substances (CO, SO2) erosion of the kiln body; 3, to prevent corrosion, material flow on the kiln body; 4, reduce the kiln temperature, kiln body to prevent oxidation 5, has the function of corrosion; thermal insulation; 6, to improve the coating performance.
Q:The difference between clay bricks and clay bricks
Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.
Q:What should be used as binder for making high alumina bricks?
Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.
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: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:What is the content of free silica in the refractory bricks of high alumina bricks?
In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.
