Abstract
The mechanical and metallurgical properties of iron and steel are significantly influenced by the contents and forms of nonmetallic elements. In order to control the chemical composition of steel precisely and rapidly, new analytical methods for nonmetallic elements have been developed. These methods are characterized by the use of a chemical sensor which is capable of detecting the specified gases simply, rapidly and sensitively. An on-line analytical method for hydrogen in molten steel and a method for continuous measurement of hydrogen which can permeate a bolt were developed by using a SnO2 semiconductor gas sensor. A method for simultaneous determination of gas mixtures was also developed using plural semiconductor gas sensors, and was applied to measuring concentrations of coke oven gases. A rapid determination method for phosphorus and sulfur in iron was also developed by using a reflectance photometric sensor with gas detecting tape. These methods are capable of being used at the production sites, and contributing to the precise control of the chemical composition of steel.
