Problems solved by technology

[0004] However, when the production rhythm of high-speed wire rod is slow, the upstream production line of the air-cooled production line often cannot send the rolled pieces to the air-cooled production line for cooling in time, which results in that there are no rolled pieces on the air-cooled production line in a certain period of time. Cooling is required, and the air-cooled fan is still rotating at the working speed at this time, which will inevitably cause a waste of energy

Embodiment Construction

[0054]Embodiments of the present invention provide a method and device for controlling an air-cooled fan, so as to save energy consumption.

[0055] First, the control method of the air-cooled fan in the embodiment of the present invention is described, as figure 1 As shown, the method at least includes the following steps:

[0056] Step S11: Detect whether there is a rolled piece on the air-cooling production line; if not, go to step S12, otherwise continue to step S11.

[0057] Among them, the air-cooled production line is equipped with detection elements, which can detect whether there is a rolled piece on the air-cooled production line; the detection elements may include hot metal detectors and pyrometers. When the detection element is specifically a hot metal detector, the hot metal detector can receive the infrared rays emitted by the rolled piece, and then enter the focus through the optical part, and directly image the image on the photosensitive device to convert th...

Abstract

An embodiment of the invention discloses an air cooling fan control method and device. The method includes: detecting whether a rolled piece exists on an air cooling production line or not; if not, judging whether a new rolled piece enters the upstream production line of the air cooling production line or not; if not, maintaining or adjusting the rotation speed of an air cooling fan as a standby rotation speed; or else, maintaining or adjusting the rotation speed of the air cooling fan as a working rotation speed, wherein the standby rotation speed is smaller than the working rotation speed. By the method and device, energy can be saved.

Description

technical field [0001] The invention relates to the technical field of steel rolling automation control, in particular to a method and device for controlling an air cooling fan. Background technique [0002] High-speed wire is one of the important products of the iron and steel industry, widely used in various infrastructure construction, construction engineering construction and metal products and other industries. The so-called high-speed wire refers to the coiled steel rolled by a high-speed rolling mill, such as Figure 9 As shown, the production process is roughly as follows: the steel billet heated by the heating furnace first enters the rough rolling production line for rolling, and the steel billet after the rough rolling is cut by flying shears; then enters the intermediate rolling production line for rolling, and after the intermediate rolling is completed From the fly shearing head; then enter the pre-finishing rolling production line for rolling, the steel billet...
