Abstract
PURPOSE: To permit the strip to hold uniform mechanical properties over the entire length, by measuring the rolling load at each point of the strip, and by deciding the coiling temperature for every specified length of the strip depending on the correlation of above measured rolling load with the carbon content.
CONSTITUTION: The pass schedule for each stand, the nominal carbon content, the aim coiling temperature corresponding to the nominal carbon content, etc., are set in the setting console 7. The coiling temperature computer 8 receives the signal from the load cell 10 against the rolling load of the final stand 3 at each measuring point set for every specified length of the strip, and computes the calculated rolling load depending on information of the setting console 7, the measured value of the strip thermometer 6 installed on the feed side of the finishing mill, etc. The variation of the carbon content at the measuring point from the nominal carbon content is operated depending on this calculated rolling load and the actual rolling load of the final stand 3, and the aim coiling temperature is operated. This aim coiling temperature is inputted to the hot run spray cooling controller 9, to control the hot run spray 4 so as to permit each measuring point to get the aim coiling temperature.
