定碳仪是分析黑色金属及其合金所必须的一种仪器。采用气体容量法定碳的单位,一般均使用国产单式或复式定碳仪。但此种仪器一直存在结构庞大,操作比较麻烦,有时容易出现较大误差,初学者不易掌握等不足之处。我们自制的7011型简易定碳仪投产三年多,使用证明:它具有结构紧凑,体积小,操作简便,测定速度快,准确度高,容易掌握等特点。一、仪器的结构
Carbonator is an instrument necessary to analyze ferrous metals and their alloys. The use of gas capacity of statutory carbon units, are generally made using single or double carbon instrument. However, this kind of instrument has a large structure, the operation is troublesome, and sometimes prone to large errors, beginners are not easy to grasp such shortcomings. Our self-made 7011-type simple carbon analyzer put into operation more than three years, the use of proof: It has a compact, small size, easy to operate, the determination of speed, high accuracy, easy to grasp and so on. First, the structure of the instrument
