Abstract

The known belt type continuous casting machine is improved in that a pair of guides for side dam block groups are disposed at opposite sides, in the widthwise direction, of a cast piece. Each of the guides includes guide beams disposed in two parallel rows displaced in direction of the thickness of the cast piece. Each of a pair of side dams which are movable in synchronism with feeding of the cast piece is formed of a side dam block group in one row. Each of the side dam block groups is divided into two sub-groups, each of which has a length longer than a contact length between the side dam block group and the cast piece and each of which is guided by a separate guide beam.

Claims9

Dependent claims

A belt type continuous casting machine for continously casting molten metal into a continuously discharged cast piece, said machine comprising:

a pair of cooled endless belts extending parallel to each other to define first opposite spaced sides of a mold space for receiving moltent metal, said belts being movable in synchronism in respective endless paths;
a pair of endless side dams extending parallel to each other to define second opposite spaced sides of said mold space, each said side dam being pinched on opposite sides thereof between said pair of endless belts, said pair of side dams being movable in respective endless paths in synchronism with said pair of endless belts;
whereby molten metal continuously introduced into said mold space is continuously moved in a casting direction while being solidified, and a resultant cast piece is continously discharged from said mold spaced;
each said side dam comprising a group of a plurality of side dam blocks arranged sequentially in contact in a single row in the respective said endless path, said group of blocks being arranged in first and second successive sub-groups, each said sub-group having a length along said respective endless path at least longer than the length of said side dam in contact with the molten metal and cast piece;
each said side dam having associated therewith a respective guide, each said guide comprising first and second movable guide beams extending parallel to each other at a position adjacent said mold space and extending along the entire length thereof in said casting direction, first and second fixed guide beams extending parallel to each other at a position spaced from said mold space, and means mounting said first and second movable guide beams on said first and second fixed guide beams, respectively, for selected independent movement toward and away from said mold space;
and
said blocks of said first sub-group being guided during movement along said respective endless path by said first movable guide beam and said first fixed guide beam, and said blocks of said second sub-group being guided during movement along said respective endless path by said second movable guide beam and said second fixed guide beam.
