Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0026] Such as Figure 1~3 As shown, the cooling spray header for the steel strip between the rolling mill stands designed by the present invention includes a manifold 2 and multiple nozzle tubes 4, among which:
[0027] The shape of the manifold 2 is represented by the central axis of the pipe as an axisymmetric curve intercepted from a conic section, and the length L of the manifold 2 along its axis of symmetry x And its opening width L y Ratio L x / L y =0.05~0.25.
[0028] A plurality of nozzle tubes 4 are arranged along the protruding side of the manifold 2, and are inclined to one side of the plane where the central axis of the manifold 2 is located, so that the central axis of the nozzle at the outlet of the nozzle 4 is the same as the central axis of the manifold 2 The angle between the planes is α=15°~60°.
[0029] The manifold 2 is divided into ...
