一、钢铁定硫:多用燃烧碘量法,此法滴定格点变色敏锐,我们应用光导管、磁通开关等创制成功了自动滴定装置。它的优点是操作轻巧、终点准确。现已应用于炉前分析,在碳硫联合测定中,减少了手工操作,节约了工时,前后经六个化验员使用,证明性能稳定,有普遍推广价值。现介绍如下,供大家参考。二、装置示意图:见图1。三、自动控制线路:见图2。四、工作原理:
First, the sulfur steel: multi-purpose combustion of iodine method, this method titration grid point sharp color, we use light pipe, magnetic flux switch and other successful creation of an automatic titration device. It has the advantage of light operation and accurate end point. Has been applied to the front analysis, in the determination of carbon and sulfur joint, reducing the manual operation, saving man hours, before and after the use of six laboratory technicians, proved stable performance, the general promotion of value. Now introduced as follows, for your reference. Second, the device diagram: See Figure 1. Third, automatic control circuit: see Figure 2. Fourth, the working principle:
