Abstract

In a continuous casting mold which comprises: a plurality of ultrasonic vibrators, fitted to the outer surface of each of the side walls of said mold, along a plurality of straight lines at prescribed intervals in the axial direction of said mold, and said plurality of straight lines being arranged at prescribed intervals; the improvement characterized in that: each of the side walls of said mold is divided into a plurality of sections corresponding to said straight lines of said plurality of ultrasonic vibrators fitted to the outer surface of each of said side walls.

This application is a continuation of application Ser. No. 473,978, filed Mar. 11, 1983, abondoned, which is a continuation of application Ser. No. 213,043, filed Dec. 4, 1980, abandoned.

Claims

1. In a continuous casting mold having side walls, and which comprises:

a plurality of ultrasonic vibrators, fitted to the outer surface of each of said side walls of said mold, along each of a plurality of spaced apart straight lines which extend in the axial direction of said mold, said plurality of ultrasonic vibrators fitted along a respective one of said plurality of straight lines being spaced apart from each other at prescribed intervals in said axial direction, said plurality of axially directed straight lines being arranged spaced apart from each other at prescribed intervals in the width direction of said mold, and said side walls of said mold being mutually independent of each other with respect to vibration waves applied by said plurality of ultrasonic vibrators to said side walls;

the improvement wherein;

each of said side walls of said mold comprises a plurality of side wall sections (3a, 3b, 3c, etc.) which are spaced apart from each other in the width direction of said mold, each of said plurality of side wall sections corresponding to a respective one of said plurality of straight lines of said plurality of ultrasonic vibrators fitted to the outer surface of each of said side walls, and each of said plurality of side wall sections having, along said respective one of said plurality of straight lines, said plurality of ultrasonic vibrators coupled to the outer surface thereof to apply vibrations to same;

whereby said plurality of side wall sections of each of said side walls of said mold are mutually independent of each other in the width direction of said mold with respect to vibration waves applied by said plurality of ultrasonic vibrators to said plurality of side wall sections, and said vibration waves caused in said plurality of side wall sections of each of said side walls of said mold by said plurality of ultrasonic vibrators substantially do not interfere with each other in the width direction of said mold.

2. The continuous casting mold of claim 1, wherein the space between adjacent ones of said plurality of side wall sections (3a, 3b, 3c, etc.) of each of said side walls of said mold is approximately 0.5 mm.

3. The continuous casting mold of claim 1, wherein each of said side wall sections (3a, 3b, 3c, etc.) of each of said side walls of said mold has, along said respective one of said plurality of straight lines, a plurality of projections (3a'"'"', 3b'"'"', 3c'"'"', etc.) extending toward the exterior of said mold, and each of said plurality of ultrasonic vibrators being attached to a respective one of said plurality of projections.

4. The continuous casting mold of claim 2, wherein each of said side wall sections (3a, 3b, 3c, etc.) of each of said side walls of said mold has, along said respective one of said plurality of straight lines, a plurality of projections (3a'"'"', 3b'"'"', 3c'"'"', etc.) extending toward the exterior of said mold, and each of said plurality of ultrasonic vibrators being attached to a respective one of said plurality of projections.
