利用薄带连铸技术生产取向硅钢具有独特的技术优势，国内外开展了大量的基础理论及工业化应用等研究工作，并形成了一些专利技术，但仍处于中试阶段.我国已在实验室条件下采用薄带连铸技术试制出取向硅钢原型钢，其中高磁感取向硅钢的磁感指标达到 B 8＝1．94 T.薄带连铸生产取向硅钢的技术难点主要集中在凝固组织控制、抑制剂析出行为、高斯种子起源、冷加工塑性等方面.本文围绕薄带连铸技术制备取向硅钢的工艺要点和难点，概述了国内外薄带连铸取向硅钢的最新研究进展.最后，指出了薄带连铸取向硅钢的研究方向.
Strip casting has a unique advantage in manufacturing grain-oriented silicon steels.A number of works concerning the fundamental research and the application of strip casting have been carried out both at home and abroad.However,they are still in the pilot phase.In China,Hi-B grain-oriented silicon steels with the B 8 up to 1.94 T have been produced under laboratory conditions based on strip casting technology.The technical difficul-ties of manufacturing grain-oriented silicon steel by using strip casting were the control of solidification micro-structure,inhibitor precipitation,origin of Goss texture,cold workability and so on.This paper summarizes the latest domestic and foreign research status of grain-oriented silicon steel based on strip casting around the key points and difficulties of the process.The recommendations for further study are listed in the final section.
