The finite difference method and 2 D steady laminar model were applied to the numerical simulation for the fluid flow inside the molten pool during unequal diameter twin roll strip cast rolling.

The finite difference method and 2 D transient heat transfer model were applied to the numerical simulation for the development of temperature distribution patterns in the molten pool and in the solidified metal layer formed on the surfaces of two opposite rotating rolls during the early stage of unequal diameter twin roll strip cast rolling process.

Based on the theory of the elastoplastic distortion,using the correlative knowledge about the three roller plate bending rolls, we sdudied how to calculate the structural parameters of the bending rollers in coilbox deeply, and concluded the main points about some important structural parameters such as the roll diameter and the roll distance.

According to the operation of reducing/sizing mill, a Standard method of steup and adjustment of roll , gap line speed , roll diameter , entry sections , tension between NTM and RSM has been established , as a guide for operator to adjust reducing/sizing mill.

Study of Heat Treating on Twin-roll Rapid Solidification AZ91 Magnesium Alloy Ribbons;

In the present study, the AZ91 magnesium alloy strip chip is prepared by twin-roll rapid solidification technique, it is find that the mi.

The development and the characterization of twin-roll thin strip continuous casting are reviewed.

The macroscopic heating, transmiting solute model and the microscopic model of solidification microstructure forming on twin roll thin strip casting process have been developed by using stream line interface, and the coupling between macroscopic and microscopic aspects has been carried out by solid fraction and macro micro time step.

As a new sort of near net shape continuous casting technology, twin roll continuous casting technology is widely attended by domestic and overseas researchers in recent years.
