湖南铁合金厂在厂党委领导下,经过三结合人员的共同努力,成功地改革了原重铬酸钠流程生产金属铬的工艺,采用氢氧化铬流程进行生产。新流程投产后,生产很快正常,产量、质量、回收率等主要技术经济指标已经赶上或正在赶上历史最好水平,而且主流程工序减少,生产周期缩短,人员节省11％左右,并减少了对环境的污染。新流程图简列如下: Hunan ferroalloy plant under the leadership of the factory party committee, through the joint efforts of the three combined personnel successfully reform the process of the original sodium chromate chromium metal production, the use of chromium hydroxide process for production. After the new process is put into production, the production will be normal soon. The major technical and economic indicators such as yield, quality and recovery rate have caught up with or are in the best historical record. Moreover, the main process is reduced, the production cycle is shortened, and the staff is saved by about 11%. Reduce the pollution of the environment. The new flowchart is as follows:
