摘　　要：为了减少环境污染,防止盐类添加剂产生有害物质,用无盐类的铝型添加剂代替有盐类的熔剂型添加剂,从外观、产生烟雾、实收率等方面分析使用铝型添加剂的可行性,并切取铸锭试片进行分析,试验结果表明使用铝型添加剂的铸锭无论低倍、高倍还是成分偏析都符合标准要求,且减少了环境污染,保护了操作人员的身心健康。To reduce environmental pollution and prevent harmful substances produced from salt addi-tives,salt-free aluminum additives are used to replace the flux additives that contain salts.The feasibility of using the aluminum additives is analyzed from the aspects of appearance,smoke generation,yield rate and so on.Specimens are taken from ingots for analysis.The results show that the ingots casted by using aluminum additives meet the relevant standard no matter by low and high-magnification inspection or in the term of composition segregation;meanwhile,the environmental pollution is reduced and the physical and mental health of operators can be protected.
