1, the T3 in T3 firebrick is to show is model specification this firebrick model is T-3, next the dimension of corresponding T-3 model is 230*114*65 (Mm) .
2, tall aluminous brick is firebrick in all material qualitative classification among them a kind, material is content of tall bauxite AL2O3 character in 55% above, firebrick pledges by material cent is: Brick of corundum of magnesia brick of silica brick of brick of argillaceous brick tall aluminium.
3, firebrick dimension is the length that expresses firebrick, wide, high numerical value, express with Mm commonly. What does firebrick dimension have? Build by laying bricks or stones of firebrick dimension foundation builds a principle, have general firebrick dimension and abnormity custom-built firebrick, firebrick produces manufacturer but according to client demand the dimension of custom-built firebrick, we say next general firebrick measure today.
4, firebrick is general firebrick and abnormity firebrick according to measurement standards cent, general firebrick is to show in kiln furnace any place can cooperate the firebrick of other measure standards to finish the build by laying bricks or stones of kiln furnace liner to build, how much is dimension of so general firebrick? Of narrow sense tell, the straight wall build by laying bricks or stones that what general firebrick points to is facilities of hot project of industrial kiln furnace is built and radiation form build by laying bricks or stones builds uses straight form firebrick, common and general norms of straight form firebrick has the norms firebrick such as T3, G1, G2, G3, G4, G5, G6,
Dimension is respectively: 230*114*65mm, 230×150×75mm, 345×150×75mm, 230×150/135×75mm, 345×150/130×75mm, 230×150/120×75mm, 345×150/110×75mm.
5, tell from broad sense respect, what general firebrick still included wedge firebrick and partial abnormity firebrick is general, wedge firebrick is to at least two end panel, flank or bedding face are 6 firebrick of symmetrical echelon norms of firebrick of common and general wedge has body; : The norms firebrick; such as Tc21, Tc22, Tc23, Tc24, Tc25, Tc26, Tc27, Tc28, Tc29, Tc30
Dimension is respectively: 114×65/35×230mm, 114×65/45×230mm, 114×65/55×230mm, 114×55/45×230mm, 114×75/45×230mm, 114×75/55×230mm, 114×75/65×230mm, 114×70/60×230mm, 114×85/55×230mm, 114×80/50×230mm.
6, what partial abnormity firebrick points to is the brick of general arch foot that build by laying bricks or stones builds place of industrial kiln furnace to use, it is one kind is less than body of build by laying bricks or stones of semicircular thrust vault of two side suffer force to prop up bricky; norms of brick of foot of common and general arch has: TJ-91, brick of 60° arch foot, TJ-92, brick of 30° arch foot, TJ-93, brick of 45° arch foot, Tj-94, brick of 60° arch foot, TJ-95, brick of 30° arch foot, TJ-96, brick of 45° arch foot,
Dimension is 132×114×230×33mm, 199×114×230×84mm, 199×114×230×36mm, 266×230×114×67mm, 199×345×73×49mm, 266×345×73×54mm.
7, the build by laying bricks or stones of furnace of facilitating industry kiln builds the size of general firebrick, reasonable firebrick cooperates build by laying bricks or stones to build, make build by laying bricks or stones of kiln furnace liner is built closer.
8, dimension of tall aluminous brick implements a standard
Dimensions Of General Bricks1998 –12–14 of size of shape of general firebrick of GB/T2992——1998 of level of state of People's Republic of China releases 1999–08–01 to carry out supervisory bureau of national quality technology to release GB/T 2992——1998 preface this standard is pair of GB/T 2992——1982 " size of general firebrick shape " , GB/T 1590——1979 " magnesia brick and appearance of magnesian silica brick and dimension " with GB/T 2074——1980 " refine copper furnace uses magnesian chromic brick appearance, incorporate its for a standard.
This standard is not equivalent to use international standard ISO 5019-1: 1984 " firebrick - dimension - the first part: Straight form brick " ; ISO 5019-2: 1984 " firebrick - dimension - the 2nd part: Wedge brick " ; ISO 5019-5: 1984 " firebrick - dimension - the 5th part: Arch foot brick " . Length of the brick in this standard reachs 345mm except the 230mm that uses international level outside, still withheld our country 300mm, 380mm and 460mm, bricky width uses the 114mm of international standard and 150mm. Bricky ply withheld 65mm and 75mm. This standard made to 3 afore-mentioned original standards following edit: —— made a written language to bricky name and main measure parameter definition, express with attached drawing or formula. —— was done to bricky date revise, cancelled code name. —— is calculated mediumly to original standard appendix the method was made compact, perfect, adapt for appendix A. —— added the intermediate dimension such as 75mm to set upright thick wedge brick and straight form brick. The size that to be on oblique plane 230mm, 300mm reachs brick of 460mm arch foot made —— revise, standard banking angle adopts 60°/30° and 50°/°40. —— expunges the different with general blame brick.
This standard rises from executive day, replace GB/T 2992——1982, GB/T 1590——1979, GB/T 2074——1980. The appendix A of this standard is standard appendix. This standard is put forward by ministry of former metallurgical industry. This standard standardizes technical committee to put in a mouth 's charge by countrywide fireproof material. This standard is in charge of drafting an unit: Wuhan is steely (group) company. This standard basically drafts a person: Xue opens country of article, 10 thousand Xiaoping, Gong Jiaxue, Gao Jianping, Founder. GB/T 2992——1998 Nep ISO 5019-1 of level of state of People's Republic of China: Nep ISO 5019-2 of size of shape of 1984 general firebrick: 1984 Dimensions Of General Bricks Nep ISO 5019-5: 1984 replace limits of GB/T 2992——1982 GB/T 1590——1979 GB/T 2074——1980 notation of date of the definition that this standard fixed general firebrick, brick, norms, dimension and dimension parameter.
This standard applies to the heat such as industrial furnace kiln to be versed in equipment brick line defines this standard to use following definition 2.1 general firebrick: Brick of brick of brick of the straight wall bricklaying that points to the hot project facilities such as industrial furnace kiln and the straight form brick that radiation form bricklaying uses, side thick wedge, perpendicular thick wedge, perpendicular wide wedge reachs arch foot brick. Brick of 2.1.1 straight form: The straight parallel that has length B, wide A and thick C body of 6 face brick brick of 2.1.2 side thick wedge (brick of abbreviation side wedge) : Size end is apart from B design to be on width, size carries dimension A big / A small design the wedge brick on ply. 2.1.3. Brick of travel of perpendicular thick wedge (brick of travel of abbreviation perpendicular wedge: ) size end is apart from B design to be on length, size carries dimension A big / the wedge travel of A small design in ply brick brick of travel of 2.1.4 perpendicular wide wedge (brick of travel of abbreviation wide wedge) : Size end is apart from B design to be on length, size carries dimension A big / A small design.
