TECHNICAL FIELD
[0001] The present application relates to the technical field of steel production, more particularly, it relates to a control method for intelligently improving hot charging efficiency. BACKGROUND
[0002] When the double high line of the rolling mill is rolling 10 gauge drawn material and 12 gauge threaded steel, the hot charging cannot keep up with the rhythm, and the cold billet needs to be inserted to prevent the generation of empty steps, thus affecting the hot charging rate.
[0003] Through research, it is found that the continuous casting steel rhythm is as follows: the billets are cut into products after being cast into strands, and then are moved to the hot charging roller by the turning mill or the steelmaking cold bed. If each group of steel is continuously sent to the rolling mill hot charging roller through the continuous casting hot charging roller, the rolling cannot keep up with the rhythm. Therefore, the continuous casting cannot continuously send to the rolling mill hot charging. Generally, three groups are a cycle, two groups are hot charging, and one group is on the cold bed. This rhythm is for the rolling mill, and the interval between the second group of hot charging and the third group of hot charging is the casting time of two groups. This is one of the reasons why the hot charging cannot keep up with the rolling rhythm. After the elevator lifts the last billet of the batch to the position, the billet pushing machine retreats to the position, and the hot charging roller advances. After the hot charging roller is in place, the elevator operates, and then the billet pushing machine operates. The operation instructions of the three devices are closely linked. However, the feeding roller has received the request for sending steel into the furnace before the elevator is in place. Therefore, it can be seen that the long time of the hot charging roller advancing is the direct reason affecting the hot charging rhythm.
[0004] The position of the billet sent by the continuous casting on the rolling mill hot charging roller directly relates to the running distance and time of the rolling mill hot charging roller. The head of the billet coming from the continuous casting is generally just over the second roller, and there is a certain distance from the hot inspection. When the hot inspection has a signal and the billet pushing machine cannot operate. In actual production control, the continuous casting hot charging roller is manually operated, and the turning mill passage blocks the operator's line of sight. When the tail of the billet reaches below the passage, the roller stops, and it is impossible to send more to the rolling mill. Therefore, the existing technology has great disadvantages and defects, and cannot realize the optimal matching of hot charging, which will cause the waste of coal gas and the reduction of production efficiency, and further cause the increase of ton steel cost and the reduction of output.
