Hot Skin Pass Mill ＆ Tension Leveler Line for Ultra High-Strength Steel
In order to reduce CO2 generated from internal combustion engines, various efforts have been made to reduce the weight of vehicles over the last few decades. High strength steel materials are indispensable for the reduction of vehicles weight.
It is for this reason, the materials used for the frames and chassis are being made of Advanced High Strength Steel (AHSS) and/or Ultra High Strength Steel (UHSS) possessing properties of not only high yield strength, but also better mechanical characteristics.
There exist strong requirements for materials to be fed to the automobile production lines to have precise dimensional accuracy, favorable physical shape and improved surface quality.
On the other hand, in the production line of UHSS material, higher rate rapid cooling with water on the run-out table is inevitable, which becomes one of the elements of lower flatness performance than conventional strips.
To produce UHSS material to the required quality, JP Steel Plantech Co. designed, manufactured and delivered a Hot Skin Pass Mill Line with Tension Leveler adopting various techniques and innovations suitable for UHSS materials. This paper introduces details of such techniques and innovations.
