Abstract
A method and a system for cooling a steel strip are disclosed. A high water volume mist cooler and a low water volume mist cooler are disposed along a direction in which the steel strip travels. The high water volume mist cooler sprays high water volume mists onto the surfaces of the steel strip to cool the steel strip, and then the low water volume mist cooler sprays low water volume mists onto the surfaces of the steel strip to cool the steel strip, thereby cooling the steel strip while suppressing the influence of transition boiling, to prevent the steel strip from having a temperature-nonuniform portion.
Claims5
A method for cooling a strip material, comprising:
- passing the strip material through a high temperature cooling zone, in which a high water volume air-water mixture is directed towards the strip material to cool the strip material;
- conveying the strip material from the high temperature cooling zone to a low temperature cooling zone thereafter;
- and
- passing the strip material through the low temperature cooling zone, in which a low water volume air-water mixture is directed towards the strip material to further cool the strip material.
A method for cooling a strip material, comprising:
- passing the strip material through a high temperature cooling zone to cool the strip material with a high water volume air-water mixture to a temperature in the vicinity of a temperature at which transition boiling occurs;
- conveying the strip material from the high temperature cooling zone to a low temperature cooling zone thereafter;
- and
- passing the strip material through the low temperature cooling zone to cool the strip material with a low water volume air-water mixture while suppressing transition boiling.
