微合金化+控冷工艺开发高强度钢筋工艺研究

STUDY ON TMCP PROCESS FOR MICROALLOY HIGH STRENGTH REINFORCED BARS

高强度钢筋在国内建筑市场正处于推广阶段,特别2008年"5.12"四川汶川大地震之后,高强度钢筋的生产量和使用量明显增多;同时随着全球经济的迅猛发展,金属、合金消耗的增多,社会资源的有限性,导致合金价格的飙升,增大了产品的生产成本;为了适应市场竞争的需要,微合金化+控冷控轧复合工艺也成为了近年国际钢铁制造业工艺技术的最新研究和发展方向。

High-strength steel in the domestic building materials market is in the promotion stage, in particular, in 2008, ＂5.12＂ earthquake Wenchuan. Sichuan high-strength steel production and the use of more than obvious. At the same time as the rapid development of the global economy, increasing consumption of metal alloy, limited social resources, leading to expensive alloy prices, increased production costs;In order to adapt to market competition, micro-alloy ＋ controlled rolling and controlled cooling process has become complex in recent years, the International Iron and Steel manufacturing process technology research and development of the latest direction.
