摘要
通过细化晶粒,既能提高钢材的强度,又能改善塑性与韧性,从而达到改善钢材质量,降低生产成本的目的。安钢根据其高速线材轧机工艺设备现状,以20MnSi钢为研究对象,通过调整化学成分,并采用控制轧制和控制冷却工艺,成功地开发生产了铁素体晶粒尺寸在4~6μm的400MPa级超细晶粒钢筋。
Refining of grain size not only increased steel strength, but also improved plasticity and toughness. Therefore, by means of the refining purposes of improving steel quality and reducing production cost were reached. According to the conditions of process and equipment in the high-speed wire rod mill of Anyang steel, the 400MPa super fine grain rebar of 20MnSi with ferrite grain size of 4~6 μm was successfully developed and produced through adjusting the chemical compositions and processing with controlled rolling and cooling techniques.
