抄録

To make clear the lubrication mechanism in the mold of continuous casting of steel, unsteady state friction analysis has been performed with the special attention to visco-elastic behaviour of the mold flux.<BR>The mold flux behaves as Maxwell type fluid. <BR>Elasticity of 10 Pa and 50 Pa are obtained at viscosity of 0.28 Pa·s and 2.3 Pa·s respectively.<BR>The difference between the obtained friction force and the predicted one as Newtonian fluid, and the phase shift of maximum friction peak become significant when the oscillation frequency exceeds 200 cpm. These transitions can be explained quantitatively by the introduction of elasticity to the mold powder characteristics.
