Summary

The devices provide for a 2-5 time increase in ingot casting procedure output and allow reducing the ingot structure by 4-10 times as compared to the casting procedure with a conventional (slit type) mold. High-speed molding makes it possible to obtain ingots of high-dispersion microstructure without any environmentally unfriendly and expensive modificators. They are used for manufacturing ingots with improved mechanical qualities and processing metal scrap to get raw stock for engineering parts.

Description

The operation of a jet mold and a spray flooded secondary cooling system device is based on uniform height and perimeter flood and spray cooling of mold jacket and ingot. Cooler sprays impacting cooled surface at right or any other specific angles significantly reduce thermal border-layer thickness at its closest proximity, which results in an increased heat-transfer factor and an improved cooling capacity for the spray flooding procedure. Uniformity of mold jacket and ingot cooling provides for a better durability of equipment and casting procedure stability and improves the quality of continuously cast ingot.
