Abstract
PURPOSE: To reduce cropping loss by performing calculation to determine position of cutting based on data obtained from the cutting length standard for applicable bars, permissible tolerances, total length after rolling and tracking of steel temperature.
CONSTITUTION: From a terminal device 71, the input of information for the contracted cutting length including standard length required and permissible tolerances is fed into a data processing device 7. Billets 10 taken out of the furnace 2 are rolled 3, 4 into bars 1, and their length and temperature are measured by a pulse generator 40 and a thermometer 42, and resulstant data inputted into the data processing device 7. The temperature 43 of bars 1 after passed through the cooling bed 5 is also inputted. The data processing device 7 makes calculation based on the information concerning length and temperatures, and the shearing machine 6, which is controlled in accordance with the results of calculation made above, cuts the steel bars accordingly.
