- Q: What's the reason of cracks in refractory bricks?
- If it is made to refractory bricks,dry in the air naturally for 10 days, then put into the drying furnace, which is certainly better than the brick is put to the furnace directly, this is not easy to crack. After all, the moisture of brick will run in the air. See the semi-finished products (not crack is really no crack), but after drying, it has cracks, this is must because moisture runs quickly in a short time. If it cracks after high temperature heat treatment, the reason is very complicated, such as after high temperature burning, temperature decreases too fast, resulting in a large temperature change, then it cracks. Or in the process of high temperature heat treatment, the internal reaction is intense, and generate some volume expanding materials, resulting in cracks and so on. Mullite Petrochemical reaction, spinel reaction and so on, the reactions of a lot of materials are the volume expansion
- Q: Where the refractory bricks rider bricks that are used for building arch and vault should be put?
- Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
- Q: several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
- In general, if the brick inside the kiln break or loose core, the bricks of whole circle should be replaced, if only mend by replacing a damage part is also ok, but the service life is shorter.
- Q: What kind of refractory brick is suitable for clinker production line of 2,500 tons?
- High alumina brick;
- Q: 90 porous brick and ordinary shale brick, clay brick difference
- Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
- Q: Blend 12% fireclay and 88% refractory cement. Moderate water and mud are used to pile up firebricks?
- Refractory bricks can irectly be liner. Lightweight mullite brick can be used for relatively longer time. If there is no mullite brick, use mud said above for some time, then continue to use by patching up.
- Q: What mud is the refractory brick made of?
- Firing with refractory clay, the main component is AI2O3
- Q: What kinds of annealing furnace refractory bricks there are?
- But the energy saving effect is good, but also can use lightwight heat insulating brick, but the price is higher than that of clay brick
- Q: Where are clay bricks or cement bricks?
- Cement brick is the use of fly ash, cinder, coal gangue, slag, chemical residue or natural sand, sea mud etc. (more than one or several kinds of raw materials) as the main raw material, made of cement coagulant, a kind of new wall materials by high temperature calcination made called cement brick.
- Q: Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
- The heat preservation effect should be taken away from the heat insulation capacity of the material. The ordinary clay brick has small heat capacity and slow heat conduction, so it is more thermal insulation.
