摘　　要：为解决650半连续拉铸机在薄带材生产环节存在的浇铸管氧化问题、降低铸坯表面氧含量,本文拟将一种氮气保护装置安装在浇铸件的外围,向空腔内注入99.99%纯度与1.4Pa的氮气,用于最大限度降低空腔内的氧气含量、削弱高温条件下铸模表面的氧化程度,致力于有效提升铜箔母材产品的质量及成品率。In order to solve the oxidation problem of casting pipe in 650 semi continuous casting machine in thin strip production and reduce the oxygen content on the surface of casting billet,a nitrogen protection device is proposed to be installed on the periphery of the casting piece,and nitrogen with 99.99%purity and 1.4pa is injected into the cavity to minimize the oxygen content in the cavity and weaken the oxidation degree of the mold surface under high temperature conditions To effectively improve the quality and yield of copper foil base metal products.
