开发了一种新型理想连续弯曲矫直曲线,通过辊列曲线的优化设计完成了对鞍钢二炼钢厂R9 300 mm直弧型板坯连铸机的连续弯曲、矫直改造,做到了铸机水平出坯线标高及外弧基准线均不变,这是传统的连续弯曲矫直曲线所做不到的。同时该辊列曲线还具有使较高温度区域铸坯的应变速率适当大于较低温度区域的应变速率的特点,以便更加充分地利用铸坯高温蠕变和应力松弛的力学特性;该曲线更适合于新铸机的设计。 A new ideal continuous bending straightening curve was developed. The continuous bending and straightening of R9 300 mm straight arc slab continuous casting machine in Anshan Iron and Steel II Steelmaking Plant was completed through the optimized design of roller curve. Level out of the blank elevation and outer arc baseline are unchanged, which is the traditional continuous bending straightening curve can not do. At the same time, the roll curve also has the characteristic that the strain rate of slab in the higher temperature region should be appropriately larger than the strain rate in the lower temperature region so as to make full use of the mechanical properties of the slab at high temperature creep and stress relaxation; the curve is more suitable In the new caster design.
