Research on Process Detecting Instrumentation for Sinter Mixture Moisture On-line Measurement

Sinter mixture is the essential material of iron production. Its moisture content is vital to iron quality. A novel process detecting instrumentation was advanced based on the sinter mixture conductance property and production condition. It was composed of a by-pass auto sample-fixed device and analytical instrumentation, respectively, an auto-correction device. The sinter mixture was sampled from the main convey belt and fixed to cube solid by the by-pass auto sample-fixed device, meanwhile, the optimum plane sensors were placed on its surface for measure its moisture content over the analytical instrumentation. Rapid weight-loss measuring device corrected the analytical instrumentation on-line and guaranteed its accuracy. On-line measurement application indicated that the process detecting instrumentation possessed good linear and reflected moisture reliable and precise.
