Complex section products have significant lightweight and functional characteristics, and the twin-roll casting (TRC) is characterized by high efficiency and short flow. Hence, the TRC process for fabricating complex section products combines both advantages and will have a broader market demand and application prospect. In this paper, the research progress in recent years is reviewed, and novel TRC processes are divided into three categories according to the product section characteristics, namely transverse variable profiled strip, longitudinal variable profiled strip, and circular section products. The essence of the TRC process of complex section products is to change the steady-state characteristics in time series and the uniform characteristics in spatial distribution into transient or nonuniform. The technical principle, deformation characteristics, influence mechanism, are systematically analyzed. The current challenges and future directions of the TRC process are discussed.

复杂型材双辊铸造工艺综述

复杂型材具有显着的轻量化和功能特性,而双辊铸件(TRC)的特点是效率高,流动性短。因此,用于制造复杂型材的TRC工艺兼有这两个优点,将具有更广阔的市场需求和应用前景。本文综述了近年来的研究进展,根据产品断面的特点,将新型的TRC工艺分为三类,即横向变截面带,纵向变截面带和圆形截面产品。复杂截面产品的TRC过程的本质是将时间序列的稳态特性和空间分布的均匀特性更改为瞬态或非均匀。技术原理 系统分析了变形特性,影响机理。讨论了TRC流程的当前挑战和未来方向。
