就低碳冷轧薄板而言,水冷法可使材料获得良好的抗时效性,但不利于提高平均应变比R值和加工硬化指数n。对生产双相钢来说,采用喷气冷却法,在材料中保留有少量的残余奥氏体,可使之具有良好的力学性能匹配。当今,用连续退火法来生产冷成 For low-carbon cold-rolled sheet, the water-cooled method can make the material good anti-aging, but not conducive to improving the average strain ratio R and work hardening index n. For the production of dual-phase steel, the use of jet cooling method, retaining a small amount of retained austenite in the material, it can have good mechanical properties match. Today, the continuous annealing method to produce cold
