Abstract
The invention relates to the field of steel grade detection, and discloses a method for determining the sulfur content by a photoelectric direct-reading spectrometer, and the method comprises the following steps: selecting a steel sample for an engine fractured connecting rod with the sulfur content of 0.004%-0.090%, and determining the sulfur content in the sample by using an infrared carbon-sulfur instrument; inputting the measured numerical value into a direct-reading spectrometer database, and carrying out intensity value analysis; fitting a sulfur content working curve of the steel grade according to the strength value, and releasing the working curve; taking a plurality of finished product samples, performing surface polishing treatment on the finished product samples, performing sulfur content valuing on the drilled scraps, and using the sample as a control sample for detecting the sulfur content of the steel grade to control the detection result of the sulfur content in the process; and grinding a to-be-tested sample of the steel grade for the engine fractured connecting rod, and calculating the sulfur content of the to-be-tested steel grade by using the established sulfur content working curve and the control sample. The method solves the problems of large workload and long period of sulfur content detection in the steel for the engine fractured connecting rod in the prior art.
Description
technical field [0001] The invention belongs to the field of steel type detection, and more specifically relates to a method for measuring sulfur content with a photoelectric direct reading spectrometer. Background technique [0002] FAS2271, the steel used for engine expansion and breaking connecting rods, has a sulfur content of 0.060%-0.070%. When smelting this steel, the process samples need to be tested for sulfur content by using an infrared carbon-sulfur analyzer. Two samples must be taken at the same time before the furnace, one The sample is used for spectral analysis, and another piece of cuttings is inspected by an infrared carbon-sulfur analyzer, and the cycle is about 7 minutes. In 10 minutes, the workload is heavy and the cycle is long, which cannot meet the needs of rapid production of the converter. Contents of the invention [0003] In order to solve the problem of large workload and long period of detection of sulfur content in the steel used for engine ...
