It is well known that surface defect is a common problem encountered in the multi-stage hot bar rolling process of carbon steel. In this study, the phenomenon was investigated by simulating the process by the finite element technique to identify the

Plastic deformation that occurs in a heavy slab during plane-strain rolling was investigated by the finite element analysis. A cylindrical pore was assumed to be located along the transverse direction of a slab. The effective strain was found to be t

This paper presents a novel casting technology designed to reduce the number of breakouts in thin slab casters. Since thin slab casting is generally performed at casting speeds greater than 4 mpm, it is extremely sensitive to sticking-type breakout.

A new kind of numerical method, Contact Element Method (CEM) with two relative coordinates, has been proposed. There are two main characteristics in this method. First, meshing is based on the contact length between the rolls or between the work roll

Since the surface defect frequently encountered in the hot bar rolling of steel can easily lead to a fatal manufacturing defect during the secondary cold forging process of bar stocks, it is necessary to minimize such a defect on the surface of hot r
