ACCELERATED COOLING METHOD OF THERMO-MECHANICAL CONTROLLED PROCESS AND THE ACCELERATED COOLING APPARATUS

摘要

PURPOSE: An accelerated cooling apparatus for heat-processing control rolling is provided to increase cooling performance and improve mechanical property. CONSTITUTION: An accelerated cooling apparatus for heat-processing control rolling comprises a cooling water injector(10), and a dry ice injector(20). The cooling water injector sprays cooling water on the upper and lower surface of hot-rolled steel material. The dry ice injector injects sprays dry ice particles on the upper and lower surfaces of the hot-rolled steel material.
