Abstract

PURPOSE: To omit the end treatment in the next process and make it possible to prevent the fusion loss of a scarfing nozzle by surely guiding the leading end of a slab to the central position of scarfing.
CONSTITUTION: A slab 3 is transferred onto the slab advancing rollers 2 of a scarfing line 1. At the time when it passes the 1st leading end detector 5, the leading end of the slab is detected and the 1st length measuring device 13 starts measuring the length of the slab. At the same time, an instruction is given to a line driving part 33 which is turn decelerates the rollers and where the leading end of the slab passes the 2nd leading end detector 9, said part decelerates the rollers further, then the slab stops upon going past a scarfer 4. Here, the rollers are run reverse to move the slab reverse. At this same instant, the measured length value from the start of the length measurement until the stoppage of the slab is subtracted by being synchronized with the reverse travel of the slab and is decided comparatively with the above-mentioned subtracted value in referring to the preset positions of the leading end detector, the measuring device and the scarfing center into consideration, whereby the leading end of the slab is surely guided to the scarfing center.
