Both needed! In fact, the insulation material contains refractory brick.
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:Whether the fire bricks are needed to be poured before construction?
It should be properly watered, according to its water absorption rate: Need to soak and dry in the shade. There is no need to do like the ordinary red brick
Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
Q:What is the name of the white clay refractory brick
Kaolin
Q:Why is the house made of refractory bricks not warm in winter
