- Q:What is the difference between a clay brick and a red brick?
- Burning bricks are generally low temperature clay brick, brick, brick high.
- Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
- The furnace arch and the furnace wall are all refractory bricks, and the refractory brick is a kind of thermal insulation material!
- Q:which kind of refractory bricks do coke oven and oxtongue brick belong to ( ) A, silica?brick B, clay brick C, high alumina brick
- Beef tongue is to regulate the flow of gas, gas flow is not the same, so is the temperature, so choose the temperature resistance brick which is clay brick only.
- Q:How to prevent high alumina refractory brick from producing crack when reproduce high alumina refractory brick?
- 1-1, on the 1 in order to prevent the emergence of crack in the production of high alumina refractory brick. 2 is appropriate, the water absorption rate of the tube mill should be controlled below 6%, the excess air coefficient controlled between level 1 and 2. The water absorption rate of clinker of bauxite with high alumina controlled under 4%-5%, making the high aluminum refractory brick burning in a smoothly and steadily weak oxidation atmosphere, and should be adjusted by thermotechnic
- Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
- 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:Can common cement mortar be used to build the lining of chimney refractory brick?
- No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement
- Q:Red brick (solid clay brick) has been banned, why do few people know?
- The red brick of hollow brick to heavy masonry, the same thickness of the wall brick, hollow brick firing than required amount of clay to about 1/3, and the consumption of coal fired brick is fired hollow bricks to smoke, emissions are also big, serious damage to the environment.
- Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?
- Sulphate aluminium cement is the best choice.
