- Q: is it correct that the higher the refractoriness is, the better refractory bricks are?
- Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
- Q: can the refractory sand be used to make refractory bricks?
- refractory bricks can be used as a refractory sand after crushing , no strength required results in the lower intensity, but the temperature is not high, so it is not recommended, but refractory bricks after the high temperature is fine because its properties are changed
- 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: Do refractory bricks need to be sent to the lab to test after arriving the site?
- Generally speaking, as long as the use of temperature is not higher than 1500 degrees, it is not required to do the test, even if the ordinary refractory brick temperature is about 1500. If the temperature is high, then you do test to determine what kind of texture of refractory brick you need
- Q: Would you please tell me how to use the simple method to identify shale brick, clay brick?
- Shale density is small, weigh in hand, feeling relatively light, clay brick is high density, relatively heavy.
- Q: The renewal of refractory brick internal the lime kiln belongs to overhaul. In the absence of production, are the replacement of valve and sporadic projects also considered overhauls? Or routine maintenance!
- The replacement of fire brick is a major overhaul. If the part causes the furnace shutdown, which is also a major overhaul, so the key of overhaul is depends on what reason it is
- Q: Red brick (solid clay brick) has been banned, why do few people know?
- Because everyone feels hollow brick is more advanced, it is for quality consideration only then change, won't be to think that regulation must use this, actually solid brick is better, won't have the risk of metope ooze water ~ but because environmental protection is not allowed to use
- Q: Whether fireclay raw materials or clinker are used when masonrying general fireclay?brick? What is the difference between raw material and clinker?
- Of course is clinker, the raw material belongs to precast block, besides, clay and chamotte are mixed with glassy water and fine powder, fine powder belongs to raw materials.
- Q: How to make the adhesion between refractory brick and the inner wall of the boiler more firm?
- High temperature resistance can also extend its service cycle. If there are conditions for the user heat resistant steel welding nails. By using high temperature high alumina brick, expansion joints can not be too large, with high-temperature adhensive paste masonry, recommend that you use the refractory brick, add the amount of long pieces of brick or rachel brick
- Q: Can porous clay bricks be made of 12 walls to bear weight?
- Porous brick refers to clay, shale and fly ash as the main raw material, porous brick after molding, roasting and hole rate of not less than 15%~30%, the pass is a round hole or non circular hole, the small size and number of loading sintered porous brick has a rectangular or circular hole, is not equivalent to as long as the bricks some hole. The utility model is mainly suitable for load-bearing walls.
