Packaging steel strip finishing setting temporal profile

Packaging steel strip finishing setting temporal profile finishing thickness setting according to the material conditions is the main task of the ( Mainly is the billet temperature, steel grade, the strip thickness and width, etc. ) And finished product requirements ( Mainly is the thickness and the finishing temperature) To determine the no-load roll gap of rolling mill. Finishing setting calculation for the first time is according to the actual test results (after roughing Thickness, width, temperature, etc. ) And finished product specifications, using mathematical model prediction calculation, to determine the load distribution of each frame, press down procedures, calculate the rolling force, determine the overhead loaded roll gap down the location of the screw. Calculation for the second time on the strip arrived at finishing mill population, according to the actual population exported from roughing to finishing through time, again use mathematical model to calculate the temperature drop to calculate temperature, setting calculation for rolling schedule again. If the actual elapsed time with the standard values of the first discrepancy is not big, also can be the second time. Third when the strip into the djinn rolling after the first and the second plane, using the measured data such as the rolling pressure calculation of adaptive value to further correction after each frame. But the strip head hardness can't represent the entire strip hardness; Wear belt can also occur when the imbalance. Although computer has this functionality, but often do not use. Finally when strip through the finishing mill group, collect the measured temperature, thickness, pressure, speed, voltage, current and other data, and feedback the signal to the computer as the adaptive and self-learning calculation, to improve the next piece of setting calculation of strip steel.
