摘　　要：在研究结晶器振动参数和保护渣耗量对低碳钢(C％<0.08)和中碳钢(0.07<C％<0.16)连铸坯振痕深度和对结晶器润滑的影响的基础上,提出了在浇铸低碳钢和中碳钢时,当连铸机在稳定浇铸过程中使负滑动时间t_N和保护渣耗量Q均取最佳值且在因工况变化短时间改变拉速时仍使t_N和Q的值始终在最佳值附近的f—V_c模型。A method for getting optimum oscillation amplitude and frequence has been proposed on the basis of researching the effect of the oscillation parameters and mold powder consumption on the oscillation mark depth of low carbon (C<0. 08%) and medium carbon (0. 07<C<0. 16%) steel slabs casted continuously. A new f-Vc pattern has also been proposed, which makes negative strip time tN and mold powder consumption Q get optimum value under steady running and be always near optimum value during understable running.
