摘要:
The present invention provides a method for cooling a rolled steel material, especially a wire rod, which comprises immersing a hot-rolled steel material in foams obtained by adding a blowing agent to water, which foams have a water content of 0.01 to 80 g/100 ml, to cool the steel material by the foams. According to this method, a product having a good quality can be stably obtained by a uniform cooling.
