Embodiment Construction
[0031] Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail:
[0032] An electric meter is installed in each hot continuous rolling steel coil production line, and a 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 the power consumption of a hot continuous rolled steel coil includes the following steps:
[0033] A. The computer periodically obtains the electricity meter readings of each hot tandem rolling production line to collect and record the electricity consumption data including the electricity meter code, collection time and electricity value. The electricity consumption data is grouped according to the electricity meter code. Record the electricity value collected each time in time sequence;

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 for industrial production, in particular to monitoring the actual power consumption of a production line of a hot continuous rolled steel coil from the time the steel billet is heated and released to the end of the coil coiling. Background technique [0002] With the advent of the era of meager profits in the iron and steel industry, how to reduce production costs is the direction that every hot rolling mill is striving to tackle. It is of great value to reduce the power consumption of production by tackling the cost of power consumption for higher products. At present, the statistical method of domestic steel mills for the production power consumption of hot continuous rolled steel coils is too rough. Divide by the number of tons produced in this time period to calculate the power consumption per ton of steel. For example, the difference between the readings of the electricity ...
