Abstract

The invention discloses an ultra-fast cooling system water valve response time measuring method and device. The method comprises the following steps: when receiving trigger operation, controlling the opening of a water valve to be a first opening, and monitoring the flow of the water valve; when the flow is stable, controlling the opening of the water valve to be a second opening; carrying out monitoring to obtain flow data in the process of changing the opening of the water valve from the first opening to the second opening and time data corresponding to the flow data; and according to the flow data and time data, outputting response time parameters of the water valve. The provided method and device solve the technical problems that that workload and work difficulty are large in a method of detecting the water valve manually, and the method is not suitable for an ultra-fast cooling system in the prior art, and realize the technical effects of reducing workload and work difficulty of on-site workers, and improving monitoring accuracy.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to a method and device for measuring the response time of a water valve in an ultra-fast cooling system. Background technique [0002] In the hot rolling process, water is often used in multiple steps, especially in the cooling stage, it is necessary to control the amount of water by controlling the water valve, so as to control the cooling speed of the strip. [0003] At present, in order to avoid water valve failures in the strip steel production process, resulting in too large or too small water flow, which affects the cooling effect, it is often necessary for staff to observe the water flow of each water valve with human eyes at regular intervals to monitor and prevent And eliminate the water valve failure in time. However, unlike the ordinary laminar flow cooling system, the ultra-fast cooling system water valves have smaller apertures and higher distribution densities, gr...
