AI Technical Summary

Technical Problem

When faced with increased demand for cooling water in the manifold of the lower surface of the strip, the existing laminar flow cooling device suffers from uneven water distribution, leading to decreased cooling efficiency and strip quality problems.

Method used

A manifold with an internal sieve plate is installed between the valve assembly and the manifold, including an inlet pipe, a distribution pipe, and branch pipes. The uniform distribution of cooling water is achieved through the design of the sieve holes on the sieve plate and the branch pipe holes.

Benefits of technology

It improves the uniform distribution of cooling water, enhances the cooling effect, increases the cooling efficiency and quality stability of strip steel, simplifies the system structure, and reduces reliance on control valves.

Abstract

The utility model relates to a manifold for laminar cooling manifold belongs to strip steel processing technical field. Manifold sets up between control valve group, manifold, manifold includes inlet pipe, water equalizing pipe, branch pipe, and cooling water passes through inlet pipe and enters manifold, and cooling water is close to even distribution to manifold. The water equalizing pipe is equipped with sieve plate, and the sieve plate disperses the water flow of inlet pipe to each branch pipe. The flow velocity in inlet pipe and branch pipe is less than or equal to 2 m / s, the cross section area of water equalizing pipe is at least 2 times of the cross section area of inlet pipe, the sieve hole area sum is at least 2 times of the cross section area of inlet pipe, the sieve hole and branch pipe hole are arranged in dislocation, when inlet pipe and branch pipe are opposite, the sieve plate does not have hole in the area of 1.5 times of inlet pipe. The position of cooling water inlet pipe of this manifold on water equalizing pipe is adjusted, and the water output of each branch pipe is still consistent, so that cooling water is evenly distributed to each manifold, and the cooling effect is improved.
