ROLLING METHOD FOR WIRE AND STEEL BAR

摘要

PURPOSE:To improve the product quality and productivity by integrally constituting a cooling pipe device of an outlet and an inlet side cooling pipe body concurrently used as a rolling material guide and rolling while cooling between rolls. CONSTITUTION:An outlet side and an inlet side pipe bodies 1 and 2 having respective guide parts 11 and 21 at the end of the bodies 1 and 2 are formed integrally into a cooling pipe device 42 through a connecting part 3. Cooling pipe bodies 12 and 22 are communicated with cooling water supplying annular bodies 15 and 25 through slit nozzles 14 and 24. A rolling material 32 is surrounded and cooled by cooling water when the cooling water is supplied into the bodies 1 and 2 from the annular bodies 15 and 25 through the slit nozzles 14 and 24. Therefore, the material 32 is efficiently cooled and rolled between rolls 31 and 41. In this method, both the rolled product quality and productivity are improved because of the improved cooling effect.
