Briefing of CSC and its R & D Activities for Metal Forming


Article Preview

China Steel Corporation was founded in 1971 being the largest integrate steel mill in Taiwan. After several stages of expansion projects, its crude steel production has reached 16.5 million tons annually. CSC has made consistent efforts on its technology innovation mainly carried out by two R & D departments. One of the major tasks of its R & D activities is to establish the advanced technologies for the manufacturing better steels and aluminum alloys as well as product application technology for downstream users. This presentation will mainly brief the research activities of CSC in the field of metal forming including rolling, sheet metal forming and thermal mechanical simulations carried out at Gleeble 3800. Work rolls with continuously variable crown (CVC) were applied to produce hot-rolled strips having precise profile and flatness. Lubrication rolling technology with high speed steel rolls was developed to diminish the wearing of work rolls at hot strip mills. The campaign life of rolling cycle was greatly prolonged. Computer-aided engineering (CAE) simulation technology of sheet metal forming has been established which proved to be an effective way to deal with the sever spring back and breakage of the cold forming of high strength steel automobile parts. Hot stamping has also been developed to support the technology innovation of CSC’s downstream customers. Flow stress and microstructure evolution during hot rolling for aluminum alloys were investigated using a Gleeble 3800 simulator. Both high strength AA5182 for can end and low earing AA3104 for can body aluminum sheets have been successfully developed.
