【Abstract】 The mould flux characteristics and concasting process parameters for concasting 3 different diameter round blooms have been analyzed. It is obtained that the effects of η-viscosity of mould flux and Vc- concasting speed on surface quality of concasting bloom are obvious, and as Φ210 mm round billet-ηV\+2 C being ～30 Pa·(m/min) 2, Φ270 mm-ηV\+2 C～8 Pa·(m/min) 2 and Φ310 mm-ηV\+2 C～4 Pa·(m/min) 2 the surface defect indexes of round blooms are lowest.更多还原
