查询词典 block coefficient

A mathematical model of the direct chill casting process for superlight Mg-Li alloy (LA141) slab has been developed using the finite differential method. Thermal boundary conditions including primary and secondary cooling conditions, have been selected based on knowledges of the physical process and the literatures. The variations of heat transfer coefficient between slab and dummy block interface resulting from the deformation of the slab have been considered.
