- 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: how much fireclay is needed for 10000 refractory bricks?
- The amount of mud used for T-3 refractory brick is 0.3KG. if the tiler is skillful, the furnace should have joint of 2mm.
- Q: What is light brick and what are the characteristics of light brick?
- The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.
- Q: What is the refractory temperature of refractory bricks?
- First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
- Q: Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
- It's certain that refractory brick is better.
- 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: Is refractory brick afraid of rain?
- High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
- 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: What is the proportion of lightweight fireclay bricks?
- The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.
- Q: How much refractory material is required for 1 million tons of coke oven
- This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
