G1, g2, g3, g4, g5, g6, g7, the norms of firebrick of clay of brick of G8 tall aluminium and build by laying bricks or stones build computation

      G1, g2, g3, g4, g5, g6, g7, g8 clay brick and tall aluminous brick, the firebrick of these a few kinds of model cooperates build by laying bricks or stones to build a circle to need to pass careful consideration. The appearance of these a few kinds of bricks, dimension pursues as follows. Hearth place can divide the cubage with every brick to calculate by bricklaying total volume. When begging every brick to count, can use area of cut of hearth bricklaying level to divide the corresponding watch area with every brick to calculate. Consider 2 ％ ～ even commonly the loss of 5 ％ . If need the weight of computational brick, the weight that uses every brick takes bricky number. Blast furnace is other place is annular cylinder or cone, fluctuate no matter layer or layer of inside and outside, want build by laying bricks or stones to give ring to come, and wedge brick must be used when build by laying bricks or stones becomes ring. Be like the ring of diameter of random of build by laying bricks or stones, need wedge brick and straight form brick to cooperate to use, like — with G-1 straight form brick and G-3 or G-5 wedge brick cooperate, brick of G-2 straight form and G-4 or G-6 wedge brick close suitably. Because the ring diameter of the requirement is different of brick of reason straight form and wedge brick cooperate amount to also differ.

If use ring of build by laying bricks or stones of brick of wedge of G-3, G-4, G-5, G-6 alone,can list type:

Nx=(2πa)/(b-b1)

— of build by laying bricks or stones of the Nx—— in type the wedge brick number of ring, piece;

A—— brick length, mm;   

B—— wedge brick is big width, mm;

B1—— wedge brick is small width, mm.

By on type is informed: The wedge brick that every ring uses counts N, concern with width of wedge brick both ends and bricky length only, and have nothing to do with ring diameter. Reach from this: Need bricky number with ring of G-3 build by laying bricks or stones  N=97 piece needs bricky number with ring of G-4 build by laying bricks or stones  N=87 piece, need bricky number with ring of G-5 build by laying bricks or stones  N=48 piece, need bricky number with ring of G-6 build by laying bricks or stones  N=54 piece

Get using step of afore-mentioned place of brick of 4 kinds of wedge alone at the same time the internal diameter of ring is ordinal it is 4150mm, 3450mm, 1840mm, 1897mm. If want build by laying bricks or stones to build the cirque of aleatoric diameter, need straight form brick and wedge brick to cooperate to use, number of brick of straight form brick can calculate by next type:

Brick of straight form of the Nz—— in Nz=(πd-nx*b1)/b type is counted, piece; Nx—— wedge brick is counted, brick after deciding, it is — constant; B1—— wedge brick is small width, mm; Width of brick of B—— straight form; Mm; D—— ring internal diameter, mm.  

Example: Try out G-3 and G-1 brick build by laying bricks or stones build internal diameter to be the cirque of 7.2 M, beg place to want wedge brick number and number of straight form brick.

Solution: Nx=97 piece

Nz=(πd-nx*b1)/b=3.14*(7200-97*135)/150=65 piece

 The accuracy of the validity of firebrick product figure and dimension has immediate effect to the close sex of body of kiln furnace build by laying bricks or stones, and the service life that the close sex of body of build by laying bricks or stones is deciding form of build by laying bricks or stones greatly, the examination of the dimension because of this firebrick goods, exterior and section is very necessary. The dimension of goods of every kinds of firebrick, exterior has a regulation in technical product technology requirement. According to kiln furnace the working requirement of each place differs, the requirement that when the project is designed, seams to bricklaying is different also, but the 3mm that normally inferior requirement cannot provide a value more than, certain and significant position is like blast furnace hearth and crucible regulation to not be more than 0.smm. The body of build by laying bricks or stones of special to having requirement, its the dimension between every goods cooperates more severe, need undertakes be constructionaled beforehand. . If firebrick goods has bigger twist, be out of shape or the range that dimension exceeded a regulation, with respect to the requirement that cannot satisfy kiln furnace build by laying bricks or stones to build. GB " the examination method of firebrick product measure, exterior and section " (does the examination content that GBlo326) provides include: ? ⒍ of  of で of ⑴ of Pi of salt of ⒘ of Suan of collapse of live abroad of benzene of ⑷ of plinth of Po of Ji Yun ⑷ sends phenanthrene correct Pi to threshold?(of palm of  of ⑸ of plinth of thin ⒃  includes hearts and black heart) , brick of head of section, a place of strategic importance and exterior of casting mouth brick are neat degree and working face and non-working surface. Be united to make dimension, visual examination normative and accurate, normally the regulation is used measure a tool technically unifiedly, made relevant provision to the measurement technique of each place. Press if dimension examination is medium clearly order goods blueprint sets, use tape or steel straightedge to measure inside, calipers is used when external diameter. The regulation when measuring vertex damage to be short of shuttle uses 3 edges the sum to have consideration, the regulation when the examination is screwy uses flat law to wait.
