【Abstract】 In this paper,a model of mold flux’s lubrication between mould and slab is developed based on heat transfer and viscous fluid mechanics.The mold flux’s thickness and the state of existence are determined by means of calculated strand and mould temperature distribution.By applying N S equation,pressure profile and velocity distribution in liquid flux and flux relative consumption are deduced.The frictional force in the upper portion of the mold is quantitatively calculated.All of these conductive to calculating the friction between the mould and the slab further.更多还原
