AI Technical Summary

Technical Problem

In a continuous moving belt metal casting machine, rigid edge constraints cause local temperature rise along the edge when the slab leaves the casting machine, resulting in uneven thermal extraction rates and longitudinal cracks.

Method used

Vertical flexible edge restraint means are employed, which includes a compressible edge stop that is able to be bent in a vertical direction to accommodate changes in thickness or height of molten metal in the casting area of the mobile mold.

Benefits of technology

Through uniform contact and uniform heat extraction, the slab has a more uniform temperature distribution in the width direction, reducing the occurrence of longitudinal cracks.

Abstract

A method for continuous casting of molten metal with a vertically flexible edge restraint is disclosed. The vertical flexible edge constraining device may confine molten metal within a moving mold cavity of a continuous metal casting apparatus. In operation, the vertical flexible edge constraining device is configured to bend in a vertical direction relative to a flow of molten metal within the moving mold cavity. The bending of the vertical flexible edge restraint in the vertical direction corresponds to a change in one of the thickness and height of the molten metal in the moving mold cavity before the molten metal travels from the upstream mold region to the downstream mold region out of the outlet end of the moving mold cavity.
