Controlled Cooling of Strip Coils on the Conveyer of a Hot-Rolling Mill

Abstract

Research shows that the controlled cooling of strip coils should not begin in storage but rather during coil transportation to the store or to the next technological operation. That increases the effectiveness of coil cooling, thanks to the greater heat content of the metal or the greater cooling rates. On the basis of the research, proposals are made for controlled cooling of strip coils in existing lines for the transportation of hot coils to stores, with slow-cooling (thermostat) sections and accelerated-cooling sections. Controlled cooling of strip coils is also possible in newly constructed and reconstructed lines that transport coils of hot-rolled strip to the next technological operation, without intermediate storage.
