- Q: What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
- It can't be the surface of coal, at least it is coal seed.
- Q: Lining of refractory bricks in rotary furnace
- The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.
- Q: The advantages of using alkalinty refractory brick?
- Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln
- Q: Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
- There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
- Q: What are 85 bricks, 95 bricks and standard bricks? What are the specifications?
- Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".
- Q: What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
- Refractory brick tunnel kiln, but if you want fire magnesia-chrome bricks, it may soon be finished, but the energy saving effect is good, using mullite bricks to sinter high alumina brick tunnel kiln burning zone is ok. Of course, if sintering is different, the refractotry bricks require different the kiln shape of tunnel kiln, preheating zone and cooling zone use high alumina brick and clay brick. what kind of products will be sintered in the future, clay brick firing zone had better use alumina hollow ball brick and mullite bricks How high the daily design capacity to achieve, thermal insulation can not be ignored, if firing silica?brick, then I am afraid there are only few finished burning bricks, what 's the purpose of the actual operation of the tunnel kiln you will build Different design of tunnel kiln use different brick, generally sintering high alumina brick and clay brick require good kiln, the cost is also very different, for example, because although the cost is higher, in addition operation is very important for the using effect and service life of the furnace, but the design of kiln type must be reasonable, otherwise it can not reach the expected effect, for example, the highest sintering temperature to achieve
- Q: Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
- They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
- Q: What is the density of the high alumina refractory brick?
- According to the quality, the general level is two point four to two point seven or so
