Description

Technical Field

[0001] The present invention relates to the technical field of steel production, and in particular to a control method and system for energy-saving intelligent matching and regulation of the oil temperature of an oil tank body and the oil temperature of inlet and outlet oil pipes in a high-speed zone of a high-speed line. Background Art

[0002] The temperature of the oil tank in the high-speed area of ​​the double-high-speed line of the steel rolling mill and the temperature of the oil inlet and outlet pipes are very important, because the oil temperature coming out of the oil tank and the oil temperature coming out of the inlet and outlet pipes directly affect the safe and stable operation of the mechanical equipment related to the high-speed area, and are also directly related to whether the rollers can be assembled safely and smoothly.

[0003] There is a big difference between the oil temperature of the entire oil tank and the oil temperature of the inlet and outlet oil pipes, including the difference in position and time, which will cause serious deviations in the actual temperature control and temperature regulation. On the one hand, the high temperature of the inlet and outlet oil pipes will directly affect the safe and stable operation of the on-site equipment. On the other hand, the low temperature of the oil tank will cause the heater to work for a long time, resulting in a large amount of electricity consumption. At the same time, intelligent water cooling and bypass water cooling are still being carried out at the inlet and outlet oil pipes, which leads to a contradictory site, that is, on the one hand, the oil tank is heated, and on the other hand, the oil in the inlet and outlet oil pipes is cooled by water, which causes a huge waste of water and electricity consumption. At the same time, the efficiency of oil temperature control is very low and there is a large lag.

[0004] Therefore, the existing technology has great drawbacks and defects. Not only is the control efficiency of oil temperature low, but there is also serious time lag. The most important thing is that it will cause waste of water and electricity consumption in the entire process, which will lead to a substantial increase in the cost per ton of steel. Summary of the Invention

[0005] The present invention provides a control method and system for matching and adjusting the oil temperature of the oil tank body and the oil temperature of the inlet and outlet oil pipes.
