The present application relates to a kind of rolling
time sequence calculation method, belong to the technical field of steel rolling
production control.The method constructs
time sequence number pair sequence with rolling piece coordinate and motion time, according to speed
system, the entire rolling piece movement process is decomposed into several one-way movement process, and each one-way movement process is divided into different speed stage with acceleration size, the starting speed, acceleration, moving distance and moving time of each speed stage are calculated in turn, with a few variable sequence, the complex rolling piece movement process is digitized, on this basis, the motion
time sequence of each one-way movement process is calculated section by section, and according to the needs, the rolling piece motion time
sequence diagram, key equipment running state time
sequence diagram etc.are drawn, greatly improve the precision and calculation efficiency of rolling time sequence calculation, it is favorable to off-line
simulation to guide
production line design, also favorable to online control to improve temperature prediction accuracy, optimize production
rhythm, improve control precision, to improve product quality and
economic benefits.
