- Title
Application of Quality Control Charts in Determination of Carbon Content in Steel Materials.
- Abstract
The application of quality control charts in the determination of carbon content in steel materials is explored. The normality tests and correctness tests are carried out on 30 sets of measurement results of GBW01307 low-alloy steel quality control samples, the mean value and standard deviation are calculated to obtain the center line, warning limit and action limit, and four quality control charts including X control chart, I control chart, R control chart and MR control chart are established. The results show that quality control charts can intuitively evaluate the accuracy and stability of testing of carbon content in steel and are applicable to process quality control of routine testing items in the laboratory.
