- Q: Small size black brick can replace refractory bricks for wood burning fireplace?
- No, black brick has no thermal insulation effect.
- Q: What are the differences between diatomite?brick and ordinary refractory bricks?
- The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
- Q: Should kiln be warmed before the ignition of the new furnace?
- New kiln should be slowly heated up, the time should be 20 days to more than 1 month!
- Q: Which is more useful, aerated concrete block or clay brick?
- In the same basic block and brick aerated concrete price, size and clay brick is basically the same, but the aerated concrete block and more environmental protection, thermal insulation, light weight, high strength and high efficiency in construction is more prominent, so the aerated concrete block soon replace clay bricks as the main material of wall.
- Q: What is the advantage for ceramic fiber material compared with refractory brick?
- Heat capacity; excellent thermal shock resistance, good chemical stability, bearing sudden cooling and heating, without oven heating and cooling ,high speed, energy saving, is 1/8 of refractory brick, construction is simple. ceramic fiber materials and refractory brick belong to refractory insulation materials; low thermal conductivity: Low bulk density, ceramic fiber material is a new type of lightweight thermal insulation material, is one of the 10 points of lightweight refractory brick,
- 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: How to count the number of loading refractory bricks?
- Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
- Q: 1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
- 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: Where are clay bricks or cement bricks?
- Are clay bricks made of ordinary buildings or clay bricks on refractory materials?. Ordinary clay brick building is a burning clay made of red brick, (that is, the original old house with a little red brick) due to its extensive use of native resources and have great pollution in firing, now in some city has banned the use of the.
- Q: Can refractory bricks be used to build a house?
- Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
