Effects of Technological Parameters on Microstructures and Properties of Low Cost Hot Rolled Dual-Phase Steel on CSP Line

摘要：

The effects of technological parameters on microstructures and properties of low cost hot rolled dual-phase steel was researched by design different finish rolling temperature, mid cooling temperature between laminar cooling and UFC (ultra fast cooling) and stable UFC rate on the same gauge strips with the same chemistry composition during the manufacture process. It is the key for controlling coil temperature to control finish rolling temperature and mid cooling temperature between laminar cooling and UFC that based on stable UFC rate precondition. The lower finish rolling temperature, with mid cooling temperature between laminar cooling and UFC, the better to form martensite is. The foundation of developing the similar productions on the similar product line was supplied. It is good to technological advancement of developing high affixation value production as hot rolled DP steel, TRIP steel etc. in CSP line.
