燃烧—碘量法测定钢铁中硫含量的实验研究

The Experimental Study of the Determination of Sulfur Contentin Steel through Burning——Iodometry

燃烧—碘量法是测定钢铁中硫含量的常用方法之一,用此法测定时炉温、助熔剂、氧气流量及适当的预热时间、淀粉水溶液的配制和使用等都对测定结果有很大的影响。本文通过大量实验,找出了最佳的测定条件。

Burning——iodometry is one of the commonly used methods for determining the sulfur content in steel. While determining, the measured result may be greatly affected by the furnace temperature, flux, oxygen flow, proper preheat time and the preparation and application of starch aqueous solution. Through some experiments, this paper presents the optimum condition for determination.
