Cutting is completed, if it is less than 6 meters, the female base being combined into greater than 6 meters is merged with subsequent cut-over plan length and is held in primary cutting
Row cutting, is sent into secondary cut after cutting；
B, secondary cut receives the green body after once cutting, and judges whether the Cutting Length of the green body in cut-over plan is full
Foot is greater than 2 meters and less than 10 meter, if it is satisfied, the cut-over plan not completed in primary cutting is executed, if conditions are not met, carrying out three
Secondary cutting；
C, it cuts three times, receives the green body after secondary cut, judge whether the cut-over plan in secondary cut is completed, if
It does not complete, is transferred to offline cutting, complete cut-over plan.
Technical effect: this cutting method is divided into cutting three times and completes cut-over plan, and primary cutting limits Cutting Length and is greater than 6
Rice, i.e., do not complete the plan for cutting short base in primary cutting, and secondary cut limits Cutting Length and is greater than 2 meters less than 10 meters, i.e.,
The short base plan of cutting not completed in once cutting can be completed in secondary cut, it can be disposably complete on one piece of long green body
At the cutting of the short base of muti-piece, so that the short base composition of muti-piece is greater than 6 meters of long green body, then cutting is concentrated in secondary cut, it is larger
The less remaining short base amount for not meeting production plan of degree, reduces stock-sales ratio, saves cost, in addition, cutting three times
It cuts for judging whether secondary cut completes all cut-over plans, if secondary cut failure causes cut-over plan not complete
At cutting can compare judgement with cut-over plan three times, generate the plan cut offline, and it is offline to notify that operator carries out
Cutting, to complete all cut-over plans, present approach reduces unplanned rate and inventory cycles, improve slab and receive rate, save
Cost, it is unplanned that the method successfully solves the slab cutting as caused by arranging plan and Equipment in production process
And the difficult point that unplanned base inventory cycle is long, secondary cut is arranged, the method successfully avoids because only that one piece or two pieces is short
Scale semifinished product and the limitation of all cutting powers, and the difficulty that can not be produced, improve completion rate of the plan.Cut three times, assign from
The plan of wire cutting solves the unplanned difficulty that system caused by causing secondary cut not complete as Equipment is misjudged
Point.
The technical solution that the present invention further limits is: described to be cut into artificial cutting offline.
Further, in step b, corresponding label, step c are carried out according to cut-over plan to green body in secondary cut
In, it cuts whether judge mark completes corresponding cut-over plan three times, as unfinished, is transferred to offline cutting, completes cut-over plan.
A kind of preceding novel sheet billet continuous casting cutting method in the step b, cuts the overall length of green body less than 12 meters.
