Hot Rolling Model for Control of Nb Bearing Steels

铌轴承钢热轧控制模型。高强度Nb轴承带钢用于减轻汽车和建筑产品的重量。这些钢的制造是具有挑战性的，因为在保持恒定的性能和带钢厚度方面遇到了困难。当前工作的目的是为Nb轴承钢开发一个模型，该模型描述了热轧过程中加工条件和成分对组织演变的影响。待开发的模型将纳入描述动态再结晶的新方法，并将导致更好的性能和尺寸控制。它也将协助新年级的发展。

Hot Rolling Model for Control of Nb Bearing Steels. High strength Nb bearing strip steels are used to reduce the weight of automotive and construction products. The manufacture of these steels is challenging because of difficulties encountered in maintaining constant properties and strip thickness. The aim of the current work is to develop a model for Nb bearing steels that describes the effect of processing conditions and composition on the microstructure evolution during hot rolling. The model to be developed will incorporate a new approach to describing dynamic recrystallization and will lead to better property and dimensional control. It will also assist in new grade development.
