Title:
VERTICAL CRACK PREVENTING METHOD IN CONTINUOUS CASTING OF THIN INGOT
Document Type and Number:
Japanese Patent JPH04300051
Kind Code:
A
Abstract:
PURPOSE: To stably prevent the generation of a vertical crack of an ingot extending over many hours with regard to the method for manufacturing a thin ingot by using a bibelt type continuous casting device.
CONSTITUTION: Generation of a vertical crack of an ingot is prevented by controlling a casting speed of ≥5m/min, and a molten metal flow velocity distribution in the velt width direction of the lower area by 600mm from a meniscus in a mold to ±0.5m/sec of an average flow velocity in the width direction.
