Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
But it depends on materials; for example, if clay brick is pink, it calls underburnt temperature is 700 degrees -900 degrees, paste red is called overdo temperature 1350 degrees -1390 degree, if the color turns heavier, it will be deformation. there are many reasons for refractory bricks sintering
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:Why is the brick instead of solid clay brick
Shale is a sedimentary rock weathering hard substance, which is relatively hard, mainly from clay minerals and small clay particles into the pressure, cementation, weathering after the formation of hard substances, such substances are relatively hard.
Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?
1, Portland cement should be. Should use aluminate cement CA625. 2, and high alumina fragment yellow sand limestone should be mixed with high temperature solution 3, add some area of reinforced steel and steel can be thin or thick, but 6mm's diameter and 50mm's spacing of steel are suggested 4, according to the situation, add CA625 about 15%, brickbat about 60% and brick powder about 25%; 5, mixing with water to cement mortar until it is slightly thicker
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
The price is high, but the the service life is not longer than the clay brick, some use high aluminia brick. Currently, there are no refractory products that can replace refractory bricks. The effect is good of choosing fireclay brick with high strength dense, low porosity clay brick. We have maken several lines of refractory bricks. Actually, if you choose good refractory brick, the service life will be very long. The kiln temperature is not high.
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 kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:How about clay bricks?
The strength of brick can be judged by the sound produced by two bricks colliding with each other.Two hands each take a brick, gently hit, such as a uniform, crisp sound, indicating brick high strength, good quality, if the collision sound hoarse or stuffy, it shows that brick strength is low.2. to observe the crack state of bricks, elliptical repeat crack if large surface of the brick on the head, like twistcore, called "spiral brick"; some bricks will be broken, the shell off angle, crack and other symptoms, hand picked up the pieces of a pinch, immediately in powder form. The inner core is yellow and honeycombed. It is called "crisp brick", which belongs to the waste brick.3. to observe the color of brick brick brick section: open, heart was uniform black, no unburned carbon brick, high strength of such. On the contrary, the intensity is low.
Q:What material is good of refractory bricks?
It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials
Q:What is sintered non clay brick?
According to the production process can be divided into sintered brick and non sintered brick, in which non fired brick can be divided into compressed brick, steam brick and autoclaved brick, etc., according to whether or not the hole can be divided into ordinary brick, porous brick, hollow brick.
