Embodiment Construction
[0014] see figure 1 A continuous casting slab cutting tracking method provided in an embodiment of the present invention includes the following steps:
[0015] Step 1. Real-time collection of the weight of the tundish, casting length, casting speed, start and end time of the casting furnace number, cutting machine position, cutting machine switch status, mold width and thickness data in the continuous casting production line.
[0016] Step 2: Obtain the casting start time Ts through the casting length greater than 0, get the start time T1 and end time T2 of all slab cutting after Ts from the cutting machine switch state, and record the sequence number of the slab until the casting length returns to 0, and the current casting time ends .
[0017] Step 3, calculate the length L of the head blank 0 And the total length of blank cutting L cut .
[0018] Step 4, according to the length L of the head blank 0 And the total cutting length L of the head blank cut Get the length L...

The invention discloses a continuous casting sheet billet cutting tracking method, and belongs to the technical field of steelmaking continuous casting cutting. The continuous casting sheet billet cutting tracking method comprises the following steps that, the length L0 of a head billet and the total cutting length Lcut of the head billet are worked out; the length Ln1 of a later sheet billet and the total cutting length Ls1 of the later sheet billet are obtained; the length Ln2 of the sheet billet when the casting length is not increased any more is obtained, and the total cutting length LS2 of the sheet billet when the casting length is not increased any more is obtained; according to the obtained length of the sheet billet, a heat number corresponding to the sheet billet is matched; according to the casting specification of a casting machine, the length range of the sheet billet is given; cutting plans are compared, and the actual sheet billet number and planned sheet billet numbers are sequentially matched; and the continuous casting molten steel yield is obtained according to the obtained length of the sheet billet. According to the continuous casting sheet billet cutting tracking method, head skin tail billets and scraped billets can be recognized, and the molten iron yield is obtained. The cutting plans can be compared, corresponding heat numbers of various sheet billets can be matched, front procedure technology data of the sheet billet are obtained so as to guide the later technology production, human factor effects are eliminated, and accuracy is high.
Description
technical field [0001] The invention relates to the technical field of steelmaking and continuous casting cutting, in particular to a continuous casting slab cutting and tracking method. Background technique [0002] The production of the continuous casting unit in the steelmaking plant is based on the production cutting plan, and the cutting instructions are written to guide the cutting machine to cut the slab. However, there are the following problems in the actual production process: the first billet, the tail billet, and the slab that encounters accidental scrapping and other information are mostly calculated and filled in by the continuous casting operator manually or not recorded, which affects the tracking of slab information; according to According to actual needs, the weight of each furnace of molten iron in steelmaking will be larger than the weight of the planned production slab, resulting in inconsistencies between the actual slab produced by each furnace of molt...
