Optimization of High Strength (HS) Products Made by Thin Slab Technology

摘要

Recent explosive growth of steelmaking capacity resulted in raw materials shortages and price increases. To mitigate the negative impact of supply-demand imbalance, conservation, re-cycling and new technology offer most promise. Thin slab casting and rolling is the lowest cost method for HS hot-band production. Microalloyed HS steels may economically satisfy the engineering needs with less steel as a replacement for commodity type carbon steels. Substitution is beneficial both to steel producer and consumer, contributes to energy savings and reduces ecologically harmful emissions. Furthermore, substitution may contribute to a sustainable rate of steel production without slowing down the rate of economic growth.
