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
Q:What's the difference between fired clay bricks and sintered porous bricks?
Fired clay brick is a common brick made of clay as the main raw material. It is divided into five strength grades MU30, MU25, MU20, MU15 and MU10 according to the compressive strength. Strength, resistance to weathering of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst divided into high-class product (A), Al (B), (C) three qualified product quality grade. Excellent products for drywall and wall decoration, wall can be used for mixing first-class products, qualified products. Medium frosted bricks should not be used for damp parts. The shape of the brick is right angled hexahedron, its nominal size is: 240MM long, 115MM wide and 53MM high. The product mark of brick is written according to the product name, category, intensity grade, quality grade and standard number.
Q:What matters should be noticed when using clay refractory bricks in a glass kiln?
There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
Q:Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
On the wall to change the gradual implementation of the policy process, as excessive wall material, porous clay brick wall reform in some areas has completed his mission to history, new material shale and shale gangue to replace clay brick emerging. In order to promote the application of porous brick technology (Kong Xin), to further implement the policy of building energy saving and wall reform work, put forward the national standard design atlas "porous brick wall building structure" 96SJ101 "and" 96SG612 structure of porous brick wall revision work of the 2003 China building standard design and research institute.
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
Q:What is the best color of refractory brick
Gules
Q:What kinds of annealing furnace refractory bricks there are?
But the energy saving effect is good, but also can use lightwight heat insulating brick, but the price is higher than that of clay brick
Q:Which is more useful, aerated concrete block or clay brick?
In the same basic block and brick aerated concrete price, size and clay brick is basically the same, but the aerated concrete block and more environmental protection, thermal insulation, light weight, high strength and high efficiency in construction is more prominent, so the aerated concrete block soon replace clay bricks as the main material of wall.
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.
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.
