Q:What kind of refractory brick is suitable for 1400 degrees shuttle kiln?
Corundum mullite is also the principle about.2 can be. use high aluminum brick, which heat storage capacity is big, but the price is more expensive, and the chilling and heating performance is not good, the .
Q:What is the advantage for ceramic fiber material compared with refractory brick?
Heat capacity; excellent thermal shock resistance, good chemical stability, bearing sudden cooling and heating, without oven heating and cooling ,high speed, energy saving, is 1/8 of refractory brick, construction is simple. ceramic fiber materials and refractory brick belong to refractory insulation materials; low thermal conductivity: Low bulk density, ceramic fiber material is a new type of lightweight thermal insulation material, is one of the 10 points of lightweight refractory brick,
Q:90 porous brick and ordinary shale brick, clay brick difference
Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
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 density of the high alumina refractory brick?
it depends on the aluminum content, the higher it contains, the larger the density is. the hjghest is 3, the lowest is 2.
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
In general, if the brick inside the kiln break or loose core, the bricks of whole circle should be replaced, if only mend by replacing a damage part is also ok, but the service life is shorter.
Q:how to test the high alumina refractory brick mixed alumina?
Test
Q:What building materials can take the place of clay bricks?
Foam concrete block is a new type of environmental protection material, the state will avoid the wall change fund, and the red brick construction units must be turned over to 8 yuan per square metre of the wall change fund.
Q:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
