Width flow uniformity online measuring device of water spraying device

Abstract

The invention discloses a width flow uniformity online measuring device of a water spraying device. The online measuring device comprises a water collecting tank main body (3) and a base (5), wherein an opening is formed in a length direction of the water collecting tank main body (3); a water collecting tank cover (4) which can be opened and closed is arranged on the opening; a water outlet pipe is arranged at the bottom of the water collecting tank main body (3); a valve (6) is arranged on the water outlet pipe; a clamping groove (2) is fixed on the base (5); multiple circular holes are formed on the clamping groove (2); and the water collecting tank main body is fixed on the circular holes by bolts. Experiment data measured by using the device disclosed by the invention and a testing method, which are a flow uniformity curve of the water spraying device in a width direction, can really reflect cooling uniformity of cooling equipment so as to provide important basic data for realizing optimization of a high efficient, continuous and uniform quenching and cooling system and provide important theoretical basis for structure property control of the novel medium thick product research and development process in steel and iron enterprises.

Description

technical field [0001] The invention relates to the technical field of plate and strip cooling, in particular to an online measuring device for measuring the uniformity of water flow along the width direction of an ultra-wide inclined jet water spray device used in the plate and strip cooling process. Background technique [0002] The inclined jet water spray device is the core cooling structure of the efficient and uniform cooling system for plates and strips. During the cooling process, the impact of the inclined jet can blow off the cooling water film on the surface of the steel plate, so that the surface of the steel plate and the cooling water can fully contact and have high heat exchange. Capable of nucleate boiling, therefore, the inclined jet water spray device has the characteristics of high cooling intensity. The uniformity of cooling along the width direction of the steel plate is an important factor affecting the shape and microstructure of the steel plate after ...
