摘要
作者对铸造材料、液态金属处理与凝固、铸造方法及CAD/CAM集成化等几方面的发展趋势进行了分析并提出一些见解,认为:轻质材料和复合材料的应用范围将扩大,对材料的应用研究需进一步加强,利用“冶金遗传性”和过滤技术,可以优化液态金属的质量;非平衡和极端条件下的凝固行为以及金属——非金属复合体系凝固过程的界面、传热、传质、液相流动、应力等问题,可能成为富有吸引力的研究课题;近无余量铸造技术是铸造与锻造、粉末冶金、塑料成形等行业竞争的王牌,在这方面气化模和反重力充型方法起重要作用;除去先进的材料与铸造方法之外,还应有先进的设计和管理,包括质量检测环节在内的CAD/CAM集成化系统,这标志着铸造科学技术发展的新阶段。
Through analysing on developing tendency of casting materials, molten metal treatment and solidation, casting method and CAD/CAM integration, the author deems that the utilization field for light metal and composite material will be extended and research on material utilization should further be strengthened. Taking the advantage of metallurgical heredity and filtration technique, the quality of molten metal can be improved. The author also considers that problems as solidation behavour under unbalance and extreme conditions, and interface, heat conduct, mass transfer and liquidus flow stress of metal-nonmetal composite system may come to be attractive for studying. Bordering on zero allowance casting technique is the trump card for foundry to compete with forging, powder metallurgy and plastic forming, and volatile pattern process and reverse gravity mold-filling will play an important role in this aspect. Besides, the author stresses that in addition to advanced material and casting method, advanced design and management are also necessitated. Quality control featured with integration system is involved, All of these indicates a new era of the development of foundry science and technology.
