Description
This paper examines the impact of chemical composition and hot rolling process parameters on the strength characteristics of low-carbon manganese steel plates with final thicknesses of 60 and 50 mm. A review of existing mathematical models was conducted to establish the influence of these factors. The model by J. Noppon and S. Chandra-Ambhorn was selected due to the similarity of variables and was partially adapted to our conditions. The application of this model indicates that the chemical elements C, Mn, and Si have the most significant impact on the strength characteristics of the plates. Among the geometric parameters, the final thickness of the plate is crucial. Although the influence of the final rolling temperature is well-documented, its impact is less pronounced in this case, likely due to the narrow range of variation in this variable. The model allows for the straightforward prediction of the strength characteristics of steel plates based on known chemical composition and hot rolling process parameters. The predicted tensile characteristics differ from actual values by a maximum of 1.22% and 1.55% for plates with final thicknesses of 60 and 50 mm, respectively. This minimal discrepancy indicates a well-established mathematical model.
