Q:how to test the high alumina refractory brick mixed alumina?
Test
Q:What kind of material is good to be laid on the kiln car, refractory brick?
Use blankets to suspend ceiling, and modules for wall
Q:What are the differences between thermal insulation bricks and refractory bricks?
Thermal insulation brick is thermal insulative; refractory brick is high temperature resistant.
Q:How many pieces of porous brick is equal to one ton?
Refractory bricks are generally classified into two types, that is, shapeless refractory materials and shaped refractory materials. Shapeless refractory material: Also known as castable refractory, is hybrid power material composed of a variety of aggregate or a kind of aggregate and one or more kinds of the mixture of adhesive particles, it should be used evenly mixed with one or more kinds of the liquid, which has strong liquidity. Shaped refractory material: The general making of firebrick, there are standard rules for the shape, can also temporarily process according to need of building and cutting. The following are the specifications. fireclay bricks 230*114*65 each block 3.0 - 3.6 kg; special-shaped fireclay brick 230*65/55*114 each block 2.8 - 3.3 kg; the reason for the weight's ranges is that because the quality is different, in general, heavy density, good quality!
Q:What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
Refractory brick tunnel kiln, but if you want fire magnesia-chrome bricks, it may soon be finished, but the energy saving effect is good, using mullite bricks to sinter high alumina brick tunnel kiln burning zone is ok. Of course, if sintering is different, the refractotry bricks require different the kiln shape of tunnel kiln, preheating zone and cooling zone use high alumina brick and clay brick. what kind of products will be sintered in the future, clay brick firing zone had better use alumina hollow ball brick and mullite bricks How high the daily design capacity to achieve, thermal insulation can not be ignored, if firing silica brick, then I am afraid there are only few finished burning bricks, what 's the purpose of the actual operation of the tunnel kiln you will build Different design of tunnel kiln use different brick, generally sintering high alumina brick and clay brick require good kiln, the cost is also very different, for example, because although the cost is higher, in addition operation is very important for the using effect and service life of the furnace, but the design of kiln type must be reasonable, otherwise it can not reach the expected effect, for example, the highest sintering temperature to achieve
Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:How to deal with the red kiln in rotary kiln?
Q:What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
And T209
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
Perlite refractory brick is classified to outer diameter and inner diameter, pay attention to the accuracy of the size when measures, after drying, contains refractory. Our clay refractory bricks use 50% soft clay and 50% flint clay clinker, sodium to blend together according to a certain granularity requirements, after molding, etc., fireclay brick, 3373 in fact, there are many kinds of refractory bricks.
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?
The same the better, it will be easy to build
