Abstract
A system for detecting the camber of a rolled material by detecting the right and left outlet side lengths of the rolled material per unit time on the outlet side of a rolling mill and also detecting the plate width of the rolled material and then subjecting the detected signals to an arithmetic processing by an arithmetic unit to calculate the radius of curvature of the plate center line of the rolled material.
Claims4
A system for detecting the camber of a rolled material, comprising:
- (a) touch rollers disposed on both right and left sides of the rolled material on the outlet side of a rolling mill;
- (b) cylinder mechanisms connected to said touch rollers for urging said touch rollers against the right and left side portions of the rolled material;
- (c) means associated with said cylinder mechanisms for detecting the cylinder positions of said cylinder mechanisms;
- (d) means dependent on the cylinder positions detected by said detecting means for detecting the plate width of the rolled material from the cylinder positions;
- (e) pulse generators connected to said touch rollers to rotate in synchronism with said touch rollers;
- (f) counters connected to said pulse generators for counting the number of pulses provided from said pulse
- (g) means connected to said counters and to said plate width detecting means for computing the curvature or radius of curvature of the camber of the rolled material occurring on the outlet side of the rolling mill on the basis of the difference in number between the pulses produced by one of said pulse generators and the pulses produced by the other pulse generator at every predetermined time period and the plate width detected by said plate width detecting means.
