Dimensions of bricks for steel-making converters
1 Range
This standard specifies the term and definition, classification, size, size and size characteristics of firebricks used for working lining of steel converter, as well as the calculation method of double wedge brick ring and ball bottom brick ring.
This standard is applicable to the shape, size and calculation method of the firebrick used for the working lining of steel converter, and the working lining of electric furnace can also be referred to.
2 Normative reference documents
The following documents are essential for the application of this document. For dated references, the date-only version applies to this document. For undated references, the latest version (including all amendment orders) applies to this document.
GB/T 2992.2 Shape and dimensions of refractory bricks – Part 2: Shape and masonry terms of refractory bricks
GB/T 8170 numerical revision rules and limit value representation and judgment
YB/T 2217 spherical top firebrick shape size
3 Terms and definitions
The terms and definitions defined in GB/T 2992.2 and YB/T 2217 and the following terms and definitions apply to this document.
3.1
Crown brick; key brick
A wedge-shaped brick with two sides angled to each other, end distance A designed in length, taper difference CD or end size C/D designed in width.
3.2
Constant median dimenisons of crown brick (P)
The middle width dimensions or average width dimensions of each vertical width wedge-shaped brick (see 3.1) P=(C+D)/2 dimensions equal to the size of the straight brick.
3.3
Median radius of crown brick (R,)
Average inner and outer radius of a single wedge brick ring laid entirely with one vertical wide wedge brick (see 3.1),R. =PA/(C-D) or R=PA/[2(P-D)].
3.4
Limited number of crown brick in each ring (K,)limited number of crown brick in each ring
Central Angle is 360 ° brick ring set wide wedge (see 3.1) on the number of most brick, according to the type K = 2 PI A/(CD) or K = A/(P – D) calculation of PI.
3.5
Down-dome brick.
With the ball bottom brick ball radius, the size of the end distance A is designed in length, the size of the end size C/D and E/F are designed in width and thickness of the ball bottom bricklaying wedge bricks. The ball bottom bricks of the converter include a center ball bottom brick, a straight ball bottom brick (see 3.6) and a wedge ball bottom brick (see 3.7).
3.6
Rectangular down-dome brick.
Ball bottom bricks that do not have a side (wide) radial radius (end width dimension C/D is not used as end distance) (see 3.5). That is, the vertical width and vertical thickness of the ball bottom brick with the distance between the size of the end A design in length, the size of the end C/D design in width and the size of the end E/F design in thickness (see 3.5).
3.7
Spherical down-domme brick
Ball bottom bricks having side (wide) radial radii (already used as the width dimensions of the end C and D and at the same time as the length of the end thickness dimensions E/G and F/H respectively) (see 3.5). That is, the end distance A is designed in length, the end distance C and D(also as the end width dimensions) are designed in width, and the end dimensions E/F, G/H, E/G and F/H are designed in thickness of the vertical width and vertical thickness of the side thick ball bottom brick (see 3.5).
4 Categories
4.1 The working lining firebricks of steel converter are divided into vertical wide wedge-shaped bricks (see Figure 1), straight shaped bricks (C=D in Figure 1), vertical wide wedge-shaped bricks of furnace cap (see Figure 2) and ball-bottom bricks.
4.2 Ball bottom bricks are divided into central ball bottom bricks (see Figure 3), wedge ball bottom bricks (see Figure 4) and straight ball bottom bricks (see Figure 5).
5 Size Brick number, size specifications and size characteristics
5.1 Vertical wide wedge bricks and straight bricks
5.1.1 Dimensions of a vertical wide wedge brick The brick number consists of two numbers, each of which is separated by a slash. The number before the slash represents the number of centimeters (cm) from A of the size end of the brick, which is equal to A/10; The number after the slash represents the number of millimeters (mm) of the wedge difference (C-D). For the converter straight brick, the number after the slash line is 0.
5.1.2 The dimension specification expression of vertical wide wedge-shaped brick (unit mm, can be omitted)AX(C/D)XB; The size specification expression of the straight brick (unit mm, can be omitted)AXCXB.
5.1.3 The size, size specifications and size characteristics of bricks shall comply with the provisions of Table 1.
