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:Do you use ceramic as offal material for refractory bricks?
Use special clinker of bauxite with high alumina as main ingredient, pulp, K2O < 0, the main component is Al2O3 which is more than 18%, it is a kind of neutral refractory material, pyrophyllite fine powder doesn't need refractory brick production process, Fe2O3 < 1, grinding - mixing - molding - sintering - packaging - delivery. A.3%.3%, Fe2O3 < 0, molding and calcined from bauxite or other raw materials with high content oxides, combined with clay, K2O < 0.5%; 3: 2, raw materials 1; 4: 325 mesh.0%:
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.
Q:Why can earth make bricks?
Therefore, it is still widely used in masonry projects such as walls, foundations and columns. However, due to the production of traditional clay brick to destroy the field, large amount of soil sampling, high energy consumption, brick from the major, high labor intensity and low efficiency in construction, it is necessary to gradually reform and replace with new materials. Some cities have banned the use of clay bricks in buildings. Brick for sintering brick and non sintered brick in accordance with the production process; according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, slag brick and lime sand brick; according to whether the hole is divided into hollow brick, brick. In addition to clay, or as raw materials for preparation of brick by using fly ash, coal gangue and shale, which is due to their chemical composition similar to clay, but because of the fineness of less clay, so the poor plastic bricks often to be mixed with a certain amount of clay, in order to increase the plasticity. The use of coal gangue and fly ash and other industrial waste residue brick, not only can reduce the environmental pollution, saving large areas of farmland clay, and can save a lot of fuel coal.
Q:The form of boiler furnace wall
Q:The brick and ordinary clay brick which is expensive
The difference is mainly the material, as for the production, the two are fired high temperature
Q:What are required for high temperature refractory bricks?
Volume density, aluminum content, soft bearing, thermal shock
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:Why should the clay bricks be watered first when they are building masonry walls?
Therefore, in order to facilitate the operation, so that the mortar has a suitable hardening and strength growth environment, to ensure the quality of masonry, bricks must be watered before use wet.
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.
