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: How to repair the boiler?: use refractory bricks and plastic refractory

Q: What is refractory brick? What is refractory clay? ?: Refractory bricks and refractory soil are all refractory materials. Generally they can be seen in the coke oven. The refractory brick is generally yellow. A steel brick is a kind of refractory brick. Its heavier several times than ordinary brick .

Q: can Methanol burn refractory brick?: The upper part of the radiation chamber of the methanol oven is made of ceramic fiber, and the lower part is generally used refractory brick.

Q: What is the difference between clay brick, glazed tile and brick?: Clay brick, clay is firing at low temperature, glazed tile is a plain brick and glaze firing head and then fired at high temperatures, the brick is completely pressed, no firing process, three higher than the price of glazed brick, the brick is higher than that of clay brick.

Q: When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?: unnecessary

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: What material are used to burn firebrick?: Alkaline series of refractory bricks &#47, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick &#47

Q: Are clay bricks radioactive?: Radiation is almost invisible, radiation is almost everywhere.

Q: does the electric kiln burner need to be sealed?: seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
