Example Embodiment

[0027] The present invention is a continuous casting and rolling logistics control method based on model calculation. A computer management system is used for model calculation, the background operating system is AIX, the background program is developed by C, the database system is oracie, and the model is coded by stored procedures. Its "four streams in one" means that four streams of continuous casting are combined into one continuous rolling production line. figure 1 Shown.

[0028] 1. Schedule an appointment for slab storage

[0029] After the continuous casting billet plan is issued to the secondary computer, the secondary computer will make a warehousing reservation according to the offline sign of the slab in the continuous casting billet plan, and designate the stacking location of the slab after it is offline.

[0030] 2. Slab pre-hanging plan

[0031] When the slab cutting starts, the secondary computer automatically corresponds to the rolling plan according to the slab spe...

Abstract

The invention provides a model calculation based continuous casting and rolling logistic control method. The method adopts a computer management system to perform model calculation, wherein a background operation system is AIX, background program adopts C programming, a database system adopts oracie, and the model is encoded in a storage process. After the system receives slab data, a model storage process is called, a transportation path is calculated according to a slab information automatic matching production plan, a roller path automatically transports slab to a specified position, a crane operation order is automatically generated for off-line warehoused slag, and a crane operation rate is reasonably dispatched and balanced; and the crane and the roller path are sealed, buffer effect of a sidesway trolley is utilized, a rolling sequence is guaranteed, and the rhythm between a casting machine and a rolling mill is matched, so that an equipment utilization rate is increased, an occupancy rate of a raw material base is reduced, a capital turnover rate is increased, and maximization of the continuous casting and rolling yield is realized.

Description

technical field [0001] The invention belongs to the technical field of continuous casting and rolling production technology, and in particular relates to a model calculation-based continuous casting and rolling logistics control method. Background technique [0002] At present, the slab logistics management of the continuous casting and rolling method is generally completed by manually commanding the crane and manually entering and tracking. There is a situation that the logistics and information flow are inconsistent, which may easily lead to confusion in the warehouse, inaccurate location, and low crane operation rate. The phenomenon of untimely delivery, low work efficiency, inventory backlog and affecting contract execution and many other problems, the situation of loose and tight during crane operation occurs from time to time, and the rhythm of continuous casting and continuous rolling does not match, it is difficult to guarantee the plan. orderly and smooth execution....
