摘 要：In the twin-roll strip casting process,molten steel solidifies by losing heat through its interface with the casting *** heat extraction along this interface has an effect on the quality of the strips and should be affected by coating,rolls’material,and cooling water flow *** is necessary to understand the effect of these casting parameters on the solidification structure of twin-roll strip casting.A three-dimensional computational domain is set up to simulate the solidification process of molten steel and heat exchange between steel strip/air,coating,rolls,and cooling water in the channel of roll *** effect of the cooling water intensity and flow intensity of molten steel in the pool on the solidification structures is studied during the thermal cycle of rolls in the twin-roll strip *** predicted results are helpful to optimize casting parameters and improve the strip quality in the twin-roll strip casting process.
