Q:Is the thickness of the kiln lining and the refractory brick the same concept?
This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
Q:The matching ratio of masonrying refractory bricks cement
Size of brickwork joint: Vertical and horizontal seam are 2 ~ 3 mm. The ratio of seam mud: Refractory clay mud 100%; per m3 dry, clean industrial water 400 ~ 600t/, no more than 3mm
Q:How to choose refractory brick
The design of size and selection of refractory brick shape mainly depend on the design of industrial furnace lining . The size and shape of refractory bricks must meet the needs of furnace refractory brick masonry, it both ensures the convenience of building and usability of thermal equipment. (such as sealing, insulation, brick grade and service life etc.). When the furnace design company designs furnace lining of refractory bricks, first it should design the size of refractory bricks or choose standard size refractory bricks, sometimes this work is done by a furnace company, sometimes it is done by furnace construction company or furnace maintenance company directly. The refractory bricks that has a certain size designed by the furnace design companies or construction companies, in addition that it should satisfy furnace operation and operation life, it also considers whether it is convenient for refractory factories to produce refractory bricks, besides, it should take into account that whether the pass rate on main production process and finished product rate is high when bricks are moulded, installed and fired. Refractory it is convenient to operate, and is convenient for refractory factory producing, the selection of shape of refractory bricks and the design of and the brick molding, and on this basis, found the relationship between the size of wedge brick, brick level and service life etc.), some even combine refractories with furnace, but each has its inherent regularity. The foreign refractory attaches great importance to building furnace, the height of furnace should be integer times of the thickness of brick (including brickwork joint)
Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
Q:How to classify light refractory bricks?
Continuous casting use silicious insulation board, silica insulating refractory brick, ceramsite lightweight refractory concrete building block and so on. 0g/ clay lightweight heat insulating brick NGO.4-1.5g/, high aluminum lightweight heat insulating brickLGO.4-0.4-1.7G/, resistance furnace Diatomite brick 0; cm3; cm3; cm3, aluminum oxide insulating refractory products
Q:Whether the fire bricks are needed to be poured before construction?
Of course, the purpose of watering is to reduce the bricks to absorb water in mortar
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
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
When the steel is made, and wear) to complete the purpose of steelmaking, the liquid inside the kiln is melted liquid steel (1550 DEG C), erosion, only the masonry of refractory brick (melt above 1550 DEG C and has a certain strength) can resist various effects of molten steel (melting
Q:should clay or refractory cement be used to lay refractory bricks?
structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low
Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
Glassy water is recommed to be used.
