Twin Roll

In twin-roll strip casting process, the temperature variation of casting roll can result in roll thermal stress and fatigue. It not only affects the thermal deformation of casting roll and the generation of the roll surface cracks significantly, but also influences the surface quality, shape and profile of the produced strip, and the service life of the casting roll. In this paper, a 3D coupling thermal-flow finite element modelling has been conducted. For twin-roll casting of stainless steel, the influences of the casting speed and liquid level in molten pool on the temperature field of casting roll have been simulated and discussed. The developed model is very helpful in optimising the processing parameters and the design of casting roll during twin-roll thin strip casting.

Continuous Strip

This study sought to examine the suitability of the continuous strip casting process as a new fabrication method for the Ag-Cu brazing alloy. Several continuous strip casting processes such as planar flow casting, melt dragging, and twin roll strip casting were applied to the manufacture of the Ag-32%Cu strip. In particular, twin roll strip casting was found to realize the best strip shaping ability and microstructural homogeneity. The effect of aging heat treatment on the microstructure and mechanical properties of a Ag-Cu strip was also investigated through tensile test, hardness test, X-ray diffraction (XRD), scanning electron microscopic (SEM) observations, and electron probe microanalysis (EPMA). Tensile results showed gradually decreasing strengths and simultaneously increasing elongation with longer aging time. An appropriate TS strength of 283 MPa and a significantly enhanced plasticity of 41% were realized with aging condition of 670oC/2hrs. Finally, twin-rolled strips 1 mm thick could be cold-rolled to a very thin strip (80~100 μm thickness). The microstructural evolution and crystalline morphologies of Ag-Cu metastable strips were also investigated and related to the mechanical properties.
