Numerical Simulation and Process Improvement on Rough Rolling of 250 mm x 280 mm Cast Bloom to 138 mm x 150 nun Billet of GCr15 Bearing Steel
When producing GCr15 bearing steel ϕ50 ~75 mm bar,there is center porosity in rolled bar. A numerical simulation is carried out to study the penetration of effective strain in the core of bar and optimize the rough rolling pass technology, increase the reduction of the first two passes from original...
