Mathematical expression for hot-rolling loads as a function of steel composition and temperature

  • R. C. Gupta


Although plain carbon steels are produced commercially, few studies seem to attempt to develop a mathematical model for applications in computer-controlled mills. An expression is proposed to calculate hot-rolling loads while rolling in austenitic regions (800–1100 °C) giving a 30% reduction in each pass. L/W=(6−37 × 10−4T) + [(7.9−73 × 10−4T) × C] + [(5.2−51 × 10−4 T) × Si] where L/W-rolling load per unit width (kN/mm) T-mean hot rolling temperature (°C) C and Si-carbon and silicon in steel (wt%) Among common alloying elements, carbon content had a more significant effect on rolling loads than silicon content, and the amount of manganese had practically no effect hence, it is not incorporated in the proposed equation.
