- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.
- Q: What's the difference between a well type annealing furnace and a box type annealing furnace?
- Box annealing furnace application: mainly used for quenching, normalizing, annealing and other conventional heat treatment equipment for steel parts. Features: 1, electric loading, high productivity, heat treatment is especially suitable for small and medium-sized parts, such as 30%, uniform temperature, intelligent digital display meter PID (pictured) automatic temperature control, high precision; 2, electric discharge loading convenient, as good; 3, door and seal the oven body is sealed automatically, without manual seal; 4, equipped with electric interlock protection device, and can prevent the fault accident due to the error. Bell type annealing furnace four bell type annealing furnace bell type annealing furnace is mainly used for annealing sheet metal in natural atmosphere and normalizing treatment of steel parts. 1, special steel, precision alloy large all fiber trolley type resistance furnace, strip, wire bright annealing. 2 、 annealing of special steel casting and forging. 3. Annealing of silicon steel sheet. 4, metal and non metal powder sintering pieces etc..
- Q: What materials are used for roof insulation?
- There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
- 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: 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: Are there any differences between insulating bricks and refractory bricks?
- Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
- 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: What causes breakage of refractory bricks?
- There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
- Q: Use of high alumina refractory bricks?
- High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.
- Q: What is the difference between fireclay bricks and high alumina refractory bricks?
- First of all, there is a difference in the material, one is clay, and one is high aluminum.Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
