CUTTER FOR INGOT IN CONTINUOUS CASTING INSTALLATION

摘要

PURPOSE:To cut an ingot automatically at an optimum cutting speed meeting the temp. of an ingot by controlling the cutting speed of the ingot in accordance with the temp. and moving distance of the ingot measured on the upper stream side of a cutter for ingots of a continuous casting installation. CONSTITUTION:A temp. measuring device 12 having a temp. detecting part 12a and a moving distance measuring means for ingots consisting of a moving distance measuring roll 13 and a pulse transmitter 14 are provided along the passage 11 of a continuous casting machine which draws an ingot 5 from a mold 3 in an arrow 9 direction. The temp. at the temp. measurng point B and the moving distance of the ingot 5 are outputted to an arithmetic processing part not shown, where the temp. of the ingot at the time when the next cutting point D arrives at the starting point A for the cutting operation and the optimum cutting speed meeting said temp. are calculated, and a command for starting the cutting is outputted at the timing when the point D arrives at the point A. Upon receiving said output, a gas cutter 10 mounts on the ingot 5 and cuts the ingot 5 with a torch 10 while moving together with the ingot.
