Title:
鋼の縦型連続鋳造装置
Document Type and Number:
Japanese Patent JP6570738
Kind Code:
B2
Abstract:
Provided is a continuous casting device for steel, said device being capable of: effectively using existing molds; preventing the rise of cooling water by means of a spray guard; effectively preventing high-temperature vapor from entering an air gap and thereby preventing corrosion and abrasion from occurring on the lower-end inner peripheral surface of the mold via the addition of a high-pressure gas discharge unit; and accommodating mold width-changing operations. The continuous casting device for steel also has excellent versatility, a long operating life, and excellent resource-saving characteristics, maintainability, and easy of assembly and disassembly. The continuous casting device is provided with: a mold having a pair of short edges and a pair of long edges; and a plurality of spray nozzles which are provided to the lower outer area of the mold and from which water is shot towards semi-finished casting products that are continuously pulled out from the mold while being supported by support rollers. The present invention is provided with a high-pressure gas discharge unit which injects high-pressure gas toward the short and long edges on the inner periphery side of the mold from a discharge port provided on the lower-end periphery of the mold.
