1, firebrick of Mo Laishi brick is built with the following kinds of build by laying bricks or stones.
(One) silica brick, it is the main breed of acidity firebrick. It basically is used at build by laying bricks or stones to build Jiao Lu, the vault of the heat of hot project kiln that also is used at furnace of to calcine of element of all sorts of glass, pottery and porcelain, charcoal, firebrick and other bearing place, bearing in the high temperature of hot-blast stove place also is used, but unfavorable it is under 600 ℃ and temperature wave motion is used in large hot project facility.
(2) argillaceous brick, it is boiler of blast furnace, hot-blast stove, heating furnace, motivation, limekiln, rotary kiln, pottery and porcelain and firebrick firing the firebrick that kiln middling uses.
(3) tall aluminous firebrick, the mineral composition of tall aluminous firebrick is corundum, Molaishi and vitreous photograph. Raw material is tall aluminous alumina and silicon line stone kind natural ore, also mix into adds Mo Laishi of alumina of electric frit corundum, agglomeration, synthesis, and the grog that presses different scale to calcine with alumina and clay. It is multi-purpose agglomeration law production. But the product still has founding brick, frit bead brick, do not bake bricks and indeterminate form firebrick. Tall aluminous firebrick is used extensively at industry of iron and steel industry, nonferrous metal and other industry.
(4) corundum firebrick, with a kind of firebrick that corundum gives priority to those who want content look, can divide for brick of agglomeration corundum brick and electric frit corundum.
1, firebrick of Mo Laishi brick- - law of flat build by laying bricks or stones
Majority of law of flat build by laying bricks or stones is used at boiler setting, also a few is use at hearth most lower level. Be in our country, law of the commonnest flat build by laying bricks or stones, the “ that is brick wall obeys law of build by laying bricks or stones of a ” . Annular bricklaying (boiler setting of image height furnace in that way) also use method of flat build by laying bricks or stones.
2, law of build by laying bricks or stones of side of — of firebrick of Mo Laishi brick
Law of side build by laying bricks or stones basically uses at two place: It is layer of the brick end the shop, for example the hearth of open-hearth furnace and heating furnace; 2 it is vault of side build by laying bricks or stones,
3, — of firebrick of Mo Laishi brick sets upright law of build by laying bricks or stones
Perpendicular build by laying bricks or stones says to establish build by laying bricks or stones again, basically use at two place: It is the stratosphere of hearth, make the same score hearth and tall hearth for example; The 2 jobs that are hearth layer, make the same score hearth for example.
It is with brick of straight body level exemple, its are the biggest when flat build by laying bricks or stones planar. Park level position; When side build by laying bricks or stones its flank (the face in also saying, 230x65 millimeter) park level position; Set upright position of level of small park when build by laying bricks or stones.
Mo Laishi brick
Firebrick build by laying bricks or stones builds body of heater:
With the lining that adiabatic brick and firebrick build by laying bricks or stones build. Layer of furnace heat insulation pledges with clay or the material build by laying bricks or stones such as tall aluminous qualitative adiabatic brick and fireproof fiber felt is built, ply is 113-300mm. Layer of boiler setting job pledges with clay firebrick build by laying bricks or stones is built, ply is 30~460mm, place of hole of starting a hole is usable arch of firebrick build by laying bricks or stones, spell step with special shaped brick or build lid strip clay qualitative firebrick. In the meantime, heat bottom of Duan Lu wall needs to add thick, in order to increase its stability, suffer the boiler setting that billet collides to be marred more easily. The boiler setting of place of hole of starting a hole waits with side tapping mouth all round burner, suffer the action such as high temperature, urgent cold urgent heat and machinery to damage the most easily. Ply of hearth job layer is 300-460mm, warm-up paragraph with sticky earthy firebrick build by laying bricks or stones is built, heat paragraph pledge with sticky earthy or tall aluminium firebrick build by laying bricks or stones is built, magnesia of a metallurgy is spread to oxidize in order to resist on its of iron sheet broken bits erode, immediate step builds usable also magnesia brick or magnesian chromic brick a covering layer. Soaking paragraph because bed of solid base soaking suffers high temperature and billet concussion, shift to wear away reach broken bits to erode wait for action, mar faster. When this place uses tall aluminous brick or magnesia brick makes working layer, service life is half an year about, convert electric frit not comes service life can lengthen stone brick or corundum brick to be controlled to 1 year. When roof is vault of bricky build by laying bricks or stones, ply of its job layer is 230~300mm, the layer of heat insulation of adiabatic brick build by laying bricks or stones that adds ply to be 120-300mm. Use condole to hang flat-roofed when, ply of its job layer is 230~250mm, adiabatic layer ply is 70mm about. The condole that condole hangs peaceful be of use hangs area of bricky high temperature useful also tall aluminous qualitative firebrick. The abnormity condole with the commonly used place below roof pressing hangs a brick not to need adiabatic layer.
The build by laying bricks or stones that is firebrick above all builds a method: Build a method about the build by laying bricks or stones of firebrick, we are common basically 3 kinds reach way of law of law of flat build by laying bricks or stones, side build by laying bricks or stones, perpendicular build by laying bricks or stones. Great majority of law of flat build by laying bricks or stones is used at boiler setting, also a few is use at hearth most lower level. In fireproof data industry, the commonnest it is law of flat build by laying bricks or stones namely, namely we often say obey law of a build by laying bricks or stones. Annular build by laying bricks or stones builds often also use law of build by laying bricks or stones of side of; of law of flat build by laying bricks or stones to basically apply at two place: It is layer of the brick end the shop, for example open-hearth furnace and the hearth; that heat up furnace 2 it is vault of side build by laying bricks or stones, for instance; of push without using one's hands of mouth of open-hearth furnace tapping sets upright law of build by laying bricks or stones last kinds namely, be called to establish build by laying bricks or stones again, basically use at two place: It is the stratosphere of hearth,
