摘　　要：依据功率法的原理,对在线检测的板坯连铸结晶器摩擦力数据进行离线研究。讨论主要的工艺参数如通钢量、保护渣、振频、铸坯尺寸及浇注温度等对摩擦力的影响。结果表明,结晶器摩擦力可为评价保护渣润滑效果和结晶器磨损状态提供依据。结晶器摩擦力随铸坯尺寸增大有增大趋势,随拉速增大和浇注温度升高有减小趋势,可为模拟计算研究提供可靠的验证数据。This paper makes an off-line analysis on on-line mould friction data in continuous slabcasting based on the power theory. It also discusses the effects of the main parameters such as pouringsteel quantity, powder, oscillating frequency, slab size and casting temperature on friction. The results showthat the mould friction is one of parameters that can be used to evaluate powder lubrication and mouldinnerface abrasion condition. The mould friction has increase trend as increase in slab size and hasdecrease trend as increase in casting speed and temperature. These data can also provide the basis forsimulative calculation.
