7双楔形砌块环形砌体中,环形砌体的外半径 4010 mm≤R<8020 mm,采用C=B=400 mm 的砌块时,砌块数量按式(1)~式(7)计算进行;环形砌体的外半径 5010 mm<R<10020 mm,采用 C-B=500 mm 的砌块时,砌块数量按式(8)~式(14)计算进行。计算示例参见附录 A。
式中:
Kx=125.7-0.01567R（1）
Kx=0.01567(8020-R)（2）
Kx=(8020-R)/63.821（3）
Kd =0.03134R-125.7（4）
Kd=0.03134(R-4010)（5）
Kd=(R-4010)/31.9105（6）
Kh=0.01567R（7）
Kx=125.7-0.01254R（8）
Kx =0.01254(10020-R)（9）
Kx=(10020-R)/79.7364（10）
Kd:=0.02508R-125.7（11）
Kd=0.02508(R-5010)（12）
Kd=(R-5010)/39.8682（13）
Kh=0.01254R（14）
式中:
Kx–小半径楔形砌块的数量,单位为块;
Kd–大半径楔形砌块数量,单位为块;
Kh–砖环总块数,单位为块;
R –所计算环形砌体的外半径,单位为毫米(mm)。
Dimensions of blocks for refractory bricks
1 Range
This standard specifies the terms and definitions of refractory blocks, the representation of dimensional brick numbers, the representation of dimensional specifications and dimensions, the dimensions and dimensions characteristics, and the calculation method of the amount of wedge-shaped blocks (ring blocks).
This standard is applicable to blast furnaces, coke ovens and rotary kilns used in metallurgical industry, and other refractory brick blocks used in industrial kilns can be used as reference.
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.

7 Double-wedge-shaped block in circular masonry, if the outer radius of the circular masonry is 4010 mm≤R<8020 mm, and C=B=400 mm blocks are used, the number of blocks is calculated according to formulas (1) to (7); When the outer radius of the ring masonry is 5010 mm<R<10020 mm, and C-B=500 mm blocks are used, the number of blocks is calculated according to formula (8) to formula (14). See Appendix A for calculation examples.式中:

Formula:
Kx- The number of small radius wedge blocks, expressed in blocks;
Kd– The number of large radius wedge blocks, expressed in blocks;
Kh– the total number of brick rings, the unit is block;
R – the calculated outer radius of the ring masonry, in millimetres (mm).
