Alumina Lining Brick Calculation Method
Rectangle Bricks Used On End Face
GA=3.14×r2 ÷(L1×W)
GA:Amount of rectangle brick radius of cylinder（cm）
L1：Length of lining brick（cm） Width of lining brick（cm）
简体
Half Rectangle Bricks Used On End Face
GB=D÷W
GB:
Amount of Half Rectangle Bricks dimeter of cylinder（cm） Width of lining brick（cm）
简体
Dosage of rectangle bricks and trapezoid bricks on cylinder of tube body
Gc=R1×R2
R1=3.14×D÷W
Gc：
Overall amount rank amount on cylinder Height of brick(cm)
L：
length of cylinder(cm) Amount of one rank dimeter of cylinder（cm）
W:
Width of lining brick（cm） Length of lining brick（cm）
R2=(L-2h)÷L1
3. Correct installation method
1. Before installation, all the partial remaining bricks, cement and rust on the inner surface should be cleared. Uneven parts should be patched, and the smooth surface be made hoarse to increase the cohesion with cement.
2. The installation gap should be within 1mm, using #425 white cement and # 107 glue as adhesive.
The installation should begin with the end faces; two end faces are both made up of rectangle bricks and half rectangle bricks. After the installation of end faces, then for cylinder installation, the cylinder is installed with rectangle bricks and trapezoid bricks. Generally speaking, the rectangle bricks are installed above all, then the trapezoid bricks followed, and so on alternate, to ensure the bottom of bricks cling to the inner wall of the cylinder closely. If the rectangle bricks can not be installed properly, the flake bricks can be used to fill up and white cement is used to fill in the gap. |
