由于铸态贝氏体钢不需热处理而在铸态下可直接得到,因此生产工艺可大大简化,从而降低了产品的成本.该钢是针对液态挤压钢质耙片而研制的.当钢的成分一定时,要获得贝氏体组织就要控制冷却条件.铸态贝氏体钢的组织是从液态开始,经连续冷却转变而形成.为真实反映Mo-Nb钢铸态组织的形成,可用CCT图模拟铸态条件,找出冷却速度与各种组织形成的规律,用以指导铸态贝氏体钢的生产. As the as-cast bainitic steel without heat treatment in the as-cast can be obtained directly, so the production process can be greatly simplified, thus reducing the cost of the product is developed for the liquid steel squeegee developed.When the steel The composition of the bainite must be controlled to control the cooling conditions.The as-cast bainitic steel is formed from the beginning of the liquid, the continuous cooling transformation to form in order to truly reflect the formation of as-cast Mo-Nb steel as-cast structure, CCT chart can be used to simulate as-cast conditions, to find the cooling rate and the formation of various laws of the organization to guide the production of as-cast bainite steel.
