Finish hot rolling method for structural steels
摘要:
The present invention provides a finish hot rolling method for structural steels capable of realizing enhanced dimensional accuracy and a uniform microstructure, using a 2-stand 3-roll finishing mill, wherein an area reduction rate of the final finishing pass is 10 to 20% and the value of an area reduction rate of the final finishing pass divided by the corresponding area reduction rate of the pass preceding the final finishing pass is 0.7 to 1.3.
