Q: What is the role of refractory brick, whether is there any books to introduce refractory bricks
Fire resistant, flame retardant, used for building stove and firewall,
Q: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
refractory castable integrally casting
Q: Shale brick and clay brick? Answer before you know it
Has the advantages of high strength, thermal insulation, heat insulation, sound insulation and other characteristics, in order to shale as the main building materials brick construction, is the biggest advantage of shale brick and clay brick traditional construction method is exactly the same, without any additional special ` construction facilities, special tools, is the best substitute for traditional clay solid brick.
Q: the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
Q: What is the difference between a clay brick and a red brick?
Clay bricks burn red and red brick. Burnt blue. Green brick.Clay bricks are called sintered clay bricks.The construction methods are the same as those of the two. No difference.
Q: Are buildings allowed to use red bricks?
Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing. Also called clay brick. Red brick technical specifications are generally from 75 to 100. Ordinary fired brick (red brick) is also called standard brick. The size is 240*115*53. (mm) red colour, sometimes dark. Ordinary clay brick has a certain strength and durability, but also because of its porous and has a certain insulation, heat insulation, sound insulation and other advantages. Therefore, it is suitable for wall materials and masonry columns, arches, chimneys, floors and foundations. Old buildings use it as building materials. Invented by the Romans, many of the remaining classical structures in Europe had red brick and brick roofs and walls.
Q: Can thick steel plate be used instead of the furnace inside the refractory brick?
It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
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: Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
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.
