FIELD: process engineering.
SUBSTANCE: proposed method relates to preparation of materials to be hot rolled at group of mill stands (16). In compliance with this method, rolled material (6) in heated in induction furnace (7). Then material (14) is descaled before rolling at mill stands (16). Note here that scale is removed from heated rolled material (10) by at least one spinning water jet from rotary descaler (13). Then temperature of rolled material (14) scale is registered by at least one temperature gage (15) and fed to controller (18). The latter defines at least one controlled magnitude (21) to be fed to adjustment component with due allowance for adjustment law and preset temperature. Note here that at least one furnace inductor (7) is controlled to make rolled descaled material (14) temperature comply with preset magnitude.
EFFECT: higher power and descaling efficiency.
