Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:What are required for high temperature refractory bricks?
good thermal shock resistance:
Q:Is the quality of refractory brick influenced if it is soaked by water
No refractory brick is not afraid of water
Q:The form of boiler furnace wall
Q:Do refractory bricks insulate heat?
It can not be generalized, generally, the insulation performance of clay is not good, but the hollow is good, such as light mullite bricks have good insulation. it depends on what kind of refractory brick
Q:How to make refractory bricks? ? ?
Can knock, use angle grinder to slowly cut off the glaze layer outside the refractory brick, and then use hand to gently tap, to compare the complete China to do the work of the destruction of the situation
Q:What materials make of clay insulating fireclay brick?
Clay insulation bricks are general according to the different origins of raw materials, not the same
Q:How to use the winding packaging machine to pack refractory bricks
Over 150KG the most common winding machine can pack, if it is light or the goods scatter, then add capping or pre-drawn device is all right.
Q:What is the size of mechanism brick and general refractory brick?
The ordinary refractory brick is 230mm long, 53mm thick; red brick is 240mm long, 115mm wide, 65mm thick,
Q:Why is there cracks in the use of refractory bricks?
Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
