Abstract

PURPOSE:To enable the length of the rolled material to be measured with good accuracy with inexpensive equipment by disposing downstream and upsteram position detectors and an operator for calculating the length of the rolled material by leaving a specified spacing from the rolling roll gouge part on the exit side of the rolling mill. CONSTITUTION:A downstream side position detector 16 is provided by leaving a distance LO from the rolling roll gouge part on the exist side of a piercer 10 having an upper roll 12, lower roll 14 and plug 15 and an upstream position detector 18 on the upstream side thereof by leaving a distance LH from the detector 16. The length L of the rolled material is calculated in an operator 26 by the formula from the abovementioned distances LO, LH, the time TL since the downstream side position detector 16 detects the rolled material until a roll bite signal device 20 detects a no- road state, the time TH since the foregoing detector 18 detects the rolled material until the detector 16 detects the rolled material, the outside diameter Dout of the rolled material, the roll gap G of the gouge part, the exit side face angle alpha of the roll, etc. In this way, the length of the rolled material may be measured with good accuracy irrespective of rolling conditions such as piercing efficiency, etc. as well as the change in rolling speed at the biting.
