为了提高定碳定硅的准确度,使热分析法快速定碳定硅工艺便于在鑄造生产中应用推广,北京工业大学研制了自动数字显示快速定碳定硅仪,并于1981年11月26日在京通过了鉴定。在北京汽車厂鑄造分厂三个多月的工艺实驗表明:仪器能自动显示鑄鉄的含碳量和含硅量,測定速度快,4分鐘左右就能測出含碳量和含硅量,具有足
In order to improve the accuracy of carbon-fixed silicon, so that the thermal analysis method of rapid carbon-fixing silicon technology is easy to promote the application in the casting production, Beijing University of Technology developed a rapid digital automatic determination of carbon Dingding silicon instrument, and in November 1981 26 Japan passed the appraisal in Beijing. In Beijing Automobile Factory Foundry Branch more than three months of process experiments show that: the instrument can automatically display the carbon content of castings and silicon content, the determination of speed, about 4 minutes can be measured carbon content and silicon content, With enough
