Abstract

PURPOSE: To work the plate steel material after hot rolling to boxes, channels, angles, etc. without forming defects such as cracks and others by subjecting the same to bending while under high temperature after leveling process.
CONSTITUTION: After a plate steel material is heated in a heating furnace 10, it is removed of the scale produced during heating with a descaling device 12. Next, it is rolled to a desired thickness by rolling mills 14. The steel material rolled at 850W950°C is corrected of internal stress with a hot leveling device 16. The steel material having been rolled at 850W950°C is corrected of internal strains by a hot leveling device 16. Since the rolling finish temperature of the steel material is high as mentioned above, the steel material is subjected to shearing with a side shear 20 and end shear 22 without going through a reheating furnace 18. Next, it is bent to desired shapes such as boxes, channels, angles and others with a hot working device 24. Since the temperature of the steel material at this point is high, even the small bending radius and 90° bending are possible and the production of cracking is obviated.
