Claims

[Scope of utility model registration request]

A first state in which a standard straight rod with a circular cross section is inserted between the upper and lower Gytronillers and the steel bar rolling roll caliber, and this standard straight rod is in contact with the upper limit surface of the roll caliber and the lower limit surface of the upper and lower guide rollers. and a second state in which the standard straight bar is in contact with the lower limit surface of the roll caliber and the upper limit surfaces of the upper and lower guide rollers. , in a device that detects the amount of vertical misalignment of the guide roller with respect to the roll caliber by measuring with two displacement meters installed between the roll caliber and the guide roller and from the difference between the measured values, the standard straight bar is Detection of misalignment between a roll caliber and a guide roller in a steel bar rolling mill provided with an adjusting means for always setting a line connecting the detection lower ends of the two displacement meters at the same position with respect to the horizontal line in the rolling direction when the two displacement meters are not inserted. Device.
