Hot profiled rolling of C40 steel: production variable’s effect on rolling performance

ABSTRACT

The usage of C40 steel bars is common in ships, mechanical, metallurgical, automobile, military hardware, and electrical construction fields. During manufacturing of these bars, roll force (RF), roll torque (RT), cropping loss (CL) and drive energy (DE) are important production variables that must be monitored for high-quality output, scrap reduction, and mill safety with minimum consumption of energy. Roll RPM, temperature of bloom, roll gap, bloom cross-section area, and diameter of roll are process characteristics that influence these response parameters. The impact of process variables on response variables during C40 steel rolling is probed in this research. To replicate the rolling procedure, FORGE® NxT 1.1 was employed. Following statistical testing, the simulated findings were validated utilizing data from experiments acquired in a bar rolling plant. The results of an analysis of variance were used to find significant model terms. There have been constructed regression models demonstrating the link between the response parameters and the process parameters.
