Q:Do refractory bricks need to be sent to the lab to test after arriving the site?
Yes, need to test physical and chemical indicators
Q:Lining of refractory bricks in rotary furnace
About 7000~10000 furnace in steelmaking, the level of maintenance and management of each plant is different! Refractory thinning relates to safety issues (equipment and people safety). i am not clear about zinc smelting! Zinc smelting may use rotary kiln! blow the zinc powder into the kiln.
Q:refractory bricks of fireclay
According to the preparation process, it can be divided into bricks, high alumina brick, magnesia brickand so on, such as refractory clay brick, and ordinary brick; according to the shape and size, it can be divided into standard brick and silica brick, it can withstand all kinds of physical and chemical changes and mechanical action at high temperature; silica brick can be used as high-temperature building materials and structural material to build kiln and kinds of thermal equipments. Refractory material and fused brick with a certain shape and size are called refractory brick for short.
Q:How to wipe off the white paint on the refractory brick (red).
Wallpaper knife should be ok
Q:What is the clay used to make the refractory brick?
Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;
Q:Can refractory bricks be used when it cracks for 1cm
3, If the crack is caused by burning or drying, then it can't be used. While if the carck is caused by refractory brick molding, it still can be used. 4, the crack is caused by refractory bricks raw materials.
Q:What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick
The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.
Q:Do refractory bricks insulate heat?
The light brick inside the brick is heat insulation brick, according to the different bulk density, the effect is also different
Q:What is the meaning of special shaped refractory brick material n-2b?
In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
High temperature prevention, warmth keeping and heat insulation.
