Measurement method of linearity of carbon rotary kiln for aluminum
1 Scope
This standard specifies the measurement method of straightness in the daily production of carbon rotary kiln.
This standard is applicable to the measurement of the straightness of carbon rotary kiln. Rotary kiln diameter ≥ 2.2m, length ≥ 45m, support points in two groups
the above.

3 Principle of the method
3.1 vertical straightness measurement principle
The use of a level to establish a horizontal datum, read from the ruler of the wheel or the cylinder is the highest point relative to the horizontal reference plane height,
And according to the diameter of the wheel and the belt and the cylinder between the top gap, calculate the rotation of the kiln bearing the center of the cylinder in the vertical direction
Relative height difference, the vertical straightness of the cylinder axis.
3.2 Horizontal Straightness Measurement Principle
The use of the theodolite in the rotary kiln side of the establishment of a kiln and kiln tail wheel center of the center line parallel to the vertical reference plane, measuring wheel
The horizontal displacement of the belt or cylinder relative to the vertical datum, calculate the horizontal displacement of the center of the belt or cylinder, and obtain the level of the cylinder axis
Straightness.
4 measuring instruments
