- Q: how to distinguish the quality of high alumina refractory brick when you buy it ?
- see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
- Q: What materials make of clay insulating fireclay brick?
- Clay insulation bricks are general according to the different origins of raw materials, not the same
- Q: What are the weak points of clay bricks?
- Clay bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay brick is made of 50% soft clay and 50% hard clay clinker, according to the requirements of a certain particle size. After molding and drying, the clay brick is burnt at high temperature 1300~1400 degrees celsius. The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2).
- Q: Whether yellow dextrin is used in refractory bricks?
- use professional mortar, do not use yellow dextrin
- Q: What are needed to make refractory bricks with micro silica?
- Micro silicon powder is used in mortar and concrete, the ore-smelting electric furnace produces a large amount of strongly volatile gases SiO2 and Si, bridges, seaports. It is ferroalloy. When smelt ferrosilicon and industrial silicon (metallic cilicon), micro silicon power is also called silica fume or condensed silica fume, dam, gas emissions and air condensate and deposit by rapid oxidation, water conservancy, airport runway, tunnel, high-rise buildings, subway, railway, highway and culvert. Application fields of silicon power are cement concrete pavement and mine roadway anchor reinforcement and etc.
- Q: Why can't gravity retaining walls be made of clay bricks?
- Gravity retaining walls are usually made of mortar stone, but no clay bricks are used.No, I don't know. It's possible to use clay bricks instead of clay bricks
- Q: 1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
- except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
- Q: What is the difference between the refractory brick and the thermal insulation brick
- Refractory bricks are used in the stove, in order to prevent from burnouting the stove under high temperature. Thermal insulation brick is used for preserving heat, is to heat preservation
- Q: What are the physical and chemical properties of refractory bricks
- The thermal shock stability, linear?change?on?reheating, softening temperature under a fixed load, compressive strength under normal strength refractoriness
- Q: What is the clay used to make the refractory brick?
- Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;
