K’d–等大端双楔形砖环中大半径楔形砖的每环极限砖数,单位为块;
K’x–等大端双楔形砖环中小半径楔形砖的每环极限砖数,单位为块;
R –所计算双楔形砖砖环的外半径,单位为毫米(mm);此时 RDx<R<Rdi;
Rdi–等大端双楔形砖环中大半径楔形砖的外半径,单位为毫米(mm);
Rdx–等大端双楔形砖环中小半径楔形砖的外半径,单位为毫米(mm)。

5 Calculation method of torpedo tank lining masonry
The lining masonry of torpedo tank is generally made up of a straight barrel section in the middle, a cone barrel section on both sides and an end wall at both ends. The end wall is built with straight bricks, and the brick design of the straight bucket section and the cone bucket section follows the general principle of the brick design calculation of the double wedge brick.
The amount of bricks in the brick ring is calculated according to the calculation method of double wedge-shaped brick laying. The two kinds of wedge-shaped bricks cooperate with the double wedge-shaped bricks built in the brick ring, and the number of large-radius wedge-shaped bricks is K. The number of small radius wedge bricks K is calculated according to formula (1) and (2). See Appendix A for calculation examples.
Formula:
Kd– The number of large radius wedge bricks, the unit is block;
Kx– Number of small radius wedge bricks, unit is block;
