So far, finished the logistics control of blank from the conticaster to the heating furnace.
When lacking steel, warning function is arranged according to stove buffer strip of the present invention.As pre-shove charge steel billet arrive the stokehold constantly greater than or corresponding steel billet tapping shove charge immediately (allowing) when constantly then arriving at the next dress steel; But will cause buffer strip to lack a steel this moment, and its decision condition then lacks a steel for buffer strip for having gone out come constantly late than a back steel with the steel in stokehold constantly to the stokehold.Report to the police this moment.
Also comprise the non-steady state adaptive strategy according to the present invention.When rolling accident took place, continuous casting billet at first entered the heating furnace buffer strip, and continuous casting reduces the steel speed of drawing simultaneously.Fill and roller-way when occupying when the heating furnace buffer strip, do not handle as accident, then steel billet rolls off the production line.When rolling line recovered to want steel, the casting machine pulling rate did not temporarily improve, and rolled off the production line by the time all to reach the standard grade again and heating furnace buffer strip in midair the time, and continuous casting can be brought up to the best and draw steel speed.

Circulation successively so far, has been finished the logistics control of blank from the conticaster to the heating furnace.
8, the single roller-way three heating furnace medium thin slabs of doubly-linked casting machine four streams according to claim 1 are directly adorned the logistics control method, it is characterized in that: when the stove buffer strip lacks steel, warning function is arranged, as pre-shove charge steel billet arrive the stokehold constantly greater than or the tapping of corresponding steel billet when constantly then arriving shove charge immediately allow just dress at the next dress steel; At this moment will cause buffer strip to lack a steel, its decision condition then is the scarce steel of buffer strip for having gone out come constantly late than corresponding steel billet with stove correspondence steel billet constantly to the stokehold, warning this moment.
9, the single roller-way three heating furnace medium thin slabs of doubly-linked casting machine four streams according to claim 1 are directly adorned the logistics control method, it is characterized in that: comprise the non-steady state adaptive strategy, when rolling accident takes place, continuous casting billet at first enters the heating furnace buffer strip, continuous casting reduces the steel speed of drawing simultaneously, when the heating furnace buffer strip is filled and roller-way when occupying, do not handle as accident, then steel billet rolls off the production line, when rolling line recovers to want steel, the casting machine pulling rate does not temporarily improve, and rolls off the production line by the time all to reach the standard grade again and heating furnace buffer strip in midair the time, and continuous casting can be brought up to the best and draw steel speed.
