Manufacturing method and equipment for steel bars with microstructure and / or compressed structure by forging and rolling |
| abstract |
(57) [Summary] (Modified) [Problem] To realize the production of products compressed to the center at a higher production rate and lower cost than forging, and the advantages of rolling and the quality of steel by forging. Combine with improvement. As a raw material, an elongate continuous cast material (20) having a forgeable steel quality, a substantially square cross section and a slanted corner region is used. This continuous cast material is continuously and alternately twisted by at least one two-roll stand 2, 3 and at least one four-roll stand 5, 7 by a forging heat at a transition temperature or higher, and furthermore, a rolled material is used. Is subjected to a multi-stage forming process with a relatively very high rolling force to produce a rolled material that is compressed to the center. |
