Energy- and Time-Saving Low Temperature Thermomechanical Treatment of Low-Carbon Plain Steel
Original language description
Reducing the energy demand is one way of cutting the cost of finished steel products. Heat treatment is a costly stage of production in this context. This paper presents a method of reducing soft annealing times. The method, termed ASR (Accelerated Spheroidization and Refinement), was employed for improving the cold formability of ferrite-pearlite steel. In this study, plain low carbon RSt-32 steel was used as the experimental material. The influence of deformation below AC1 temperature on grain refinement and carbide spheroidization, as well the influence of temperature cycling around AC1 temperature within temperature intervals of various widths were explored. In addition, attention was paid to the effects of holding time between deformation steps and to the amount of deformation heat. Initial lamellar pearlite was converted into a recrystallized structure with fine ferrite grain of about 3 ?m size and fine spheroidized cementite. The final hardness was about 150 HV10.
