Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:
[0032] An electric meter is installed in each hot continuous rolling steel coil production line, and the communication connection between the electric meter of each hot continuous rolling steel coil production line and the computer used for power consumption monitoring is established, and the information processing is completed by the computer. The method for monitoring power consumption of hot continuous rolled steel coils comprises the following steps:
[0033] A. The computer periodically obtains the readings of the electric meters of each hot rolling production line to collect and record the electricity consumption data including the code of the electric meter, the time of collection and the value of the electricity. Record the power value of each collection in sequence in time;
[0034] B. Obtain the production time node information and working co...

The invention discloses a power consumption monitoring method for hot continuous rolling of steel coils, and relates to the technical field of power consumption control in industrial production. The method comprises the following steps: A, cyclically acquiring and recording power consumption data of each hot continuous rolling production line, grouping the power consumption data by electricity meter codes, and sequentially recording electric quantity values acquired each time according to acquisition time in each group; B, obtaining production time node information including released time, coiling ending time and rolling termination starting and ending time of each steel coil in a production control system; C, judging the time periods of production time nodes in the acquisition time sequences of the power consumption data groups in the step A respectively, and making a calculation by an interpolation method according to the electric quantity values corresponding to the acquisition time at the two ends of the time period respectively to obtain the production power consumption and rolling termination power consumption of the steel coil. According to the method, the problem that a conventional method for calculating average power consumption by dividing total production tonnage by total power consumption is inaccurate can be solved and the production power consumption of the steel coil can be accurately monitored.
Description
technical field [0001] The invention relates to the technical field of power consumption control in industrial production, in particular to a method for monitoring the actual production power consumption of a hot continuous rolling steel coil from a steel billet heated out of the furnace to a production line at the end of coil coiling. Background technique [0002] With the advent of the meager profit era of the iron and steel industry, how to reduce production costs is the direction that every hot rolling mill is working hard to tackle. As one of the main cost consumptions of hot rolling production lines, power consumption costs are targeted. Research on power consumption cost of higher products is of great value to reduce production power consumption. At present, domestic steel mills have too rough a statistical method for the production electricity consumption of hot-rolled steel coils. Divide by the number of tons produced in the time period to calculate the electricity...
