Cooling tubes for wire stocks |
摘要 |
A cooling tube for cooling a hot rolled wire stock by cooling liquid is divided into a plurality of cooling sections by spaced apart partition members. Each partition member comprises a nozzle like rotary member having an axial passage for passing the wire stock. The inlet opening of the passage is circular having a diameter slightly larger than the major axis of the maximum oval cross-sectional configuration which is formed for the hot rolled wire stock when its size is changed, while the outlet opening is an oval having a major axis equal to the diameter of the inlet opening and a minor axis slightly larger than the diameter of the circular portion of the wire stock having the maximum diameter. The cross-sectional configuration of the passage gradually changes from the inlet opening to the outlet opening to prevent leakage of the cooling liquid.
