AI Technical Summary
The existing 20-roll mill strip cooling mechanism results in poor temperature uniformity on the strip surface after cooling, making it difficult to meet the requirements of high-grade silicon steel (HIB steel).
Design a strip cooling mechanism including two liquid inlet pipes, each equipped with a flow control valve, which is connected to the upper and lower spray beams respectively. By controlling the emulsion flow rate and spray direction, the contact time and uniformity of the upper and lower surfaces are ensured. Multiple branch pipes are used to connect to the spray beams to adapt to narrow spaces, avoid interference, and improve the uniformity of emulsion output.
It improves the temperature uniformity of the upper and lower surfaces of the strip, reduces modification costs and difficulty, enhances the cooling effect, and adapts to the installation requirements of narrow spaces.
