摘　　要：Ultra Fast Cooling is a new technology which used to control the hot-rolling strip cooling in recent years on the international developed.It can achieve fast and accurate temperature control in the hot-rolled strip production process to obtain corresponding transformation microstructure and ideal mechanical properties.This article describes the technical principle and layout of ultra fast cooling in hot-rolled as well as cooling features.Analysis the effect of front ultra fast cooling technology in C-Mn steel and obtained consequent on the industrial produced low-cost Q345 hot rolled steel in Panzhihua Iron and Steel.Ultra Fast Cooling is a new technology which used to control the hot-rolling strip cooling in recent years on the international developed.It can achieve fast and accurate temperature control in the hot-rolled strip production process to obtain corresponding transformation microstructure and ideal mechanical properties.This article describes the technical principle and layout of ultra fast cooling in hot-rolled as well as cooling features.Analysis the effect of front ultra fast cooling technology in C-Mn steel and obtained consequent on the industrial produced low-cost Q345 hot rolled steel in Panzhihua Iron and Steel.
