ENERGY AND POWER PARAMETERS OF ROLLING PROFILES FOR WHEEL RIMS WITH REDUCED METAL INTENSITY AND TAPERED SEATS

Abstract

Analysis of experimental data on rolling asymmetric thin-walled sections with reduced metal consumption can be useful in identifying the features and prospects of application of profiles with reduced metal intensity, allowing obtaining significant economic and technological effects in production. The most mass-produced lightweight rim profiles 7.0-20-03 and 8.5-20-03 were studied to find the energy and power parameters. Rolling force, motor voltage current, revolutions and strip temperature were determined. The experimental data obtained indicate the possibility of mass production of high-performance rolled products for the automotive industry.
