钢锭锭型与锭模设计中的关键参数探析

Analysis on Critical Parameter of Ingot Type and Design of Ingot Mould

国内特殊钢企业生产高端钢锭普遍存在着钢锭内部质量差、锭模损耗高和钢锭成材率低等问题。本文结合近几年长城特钢联合某院校在锭型和锭模优化方面的经验和进展,从影响成材率的锭型设计参数和影响锭模质量的关键因素等方面,综合论述了在钢锭生产过程中应当注意的主要因素,也分析了铸造过程计算机模拟仿真技术对研究钢锭凝固过程的应力以及内部缺陷,优化锭型设计参数等方面的作用。旨在对企业优化锭型设计,合理设计浇铸过程工艺参数,提高成材率等有所帮助。

National special steel enterprises have the issues such as bad internal quality ,high loss of ingot mould and low yield during production of high-end ingot. This paper combined the experience and progress of Changchen Special Steel Company and a university in terms of optimization of ingot type and ingot mould,and of the design parameter of ingot type that affect yield and quality of ingot mould, discussed the major factors that should be attentioned in the course of production of ingot, and also analyzed the function of computer analog simulation technology on studying the stress and internal defect during the solidification of ingot and optimization of ingot type design parameter with an aim to optimize the design of ingot type, reasonable design process parameter during casting and increase yield.
