Abstract

A method and apparatus for semi-horizontal continuous casting is disclosed employing an essentially horizontally extending continuous casting mold provided at its upper side or top wall with a mold inlet opening for the infeed of the metal to be cast, especially steel. At least one strand guide arrangement serves to guide at least one continuously cast strand which is fed laterally out of the continuous casting mold. The strand guide arrangement for each stand possesses two strand guide tracks or paths curved in opposite direction, the center of curvature of the first curved guide track or path, viewed in the direction of travel of the cast strand, being located below its related path of travel, and the center of curvature of the second curved guide track or path being located above its related path of travel.

Dependent claims

A method of continuously casting metal strands, especially steel strands, comprising the steps of:

introducing molten metal to be cast into an essentially horizontally extending, metallic continuous casting mold through a mold inlet opening at an upper wall of the metallic mold, said metal being introduced in a direction substantially normal to the longitudinal axes of the cast strands;
withdrawing two partially solidified strands from opposite lateral outlet openings of the continuous casting mold;
guiding each of the withdrawn cast strands along two strand guide tracks curved in opposite direction to a level which is lower than the level of the continuous casting mold;
cooling the thus withdrawn cast strands;
thereafter straightening the withdrawn cast strands;
employing as the continuous casting mold a curved continuous casting mold having a predetermined center of curvature;
and
said step of guiding each of the withdrawn cast strands includes guiding at least one of the withdrawn cast strands along its strand guide track such that at least a portion of said at least one withdrawn cast strand is curved so as to possess a predetermined center of curvature which is located on an opposite side of said withdrawn cast strand than the location of said predetermined center of curvature of said curved continuous casting mold.

A continuous casting installation for the continuous casting of molten metal, especially steel, comprising:

an essentially horizontally extending continuous casting mold having an upper mold wall;
said upper mold wall being provided with a mold inlet opening for the infeed of the molten metal which is to be cast and at least one outlet opening for a cast strand;
a strand guide arrangement for at least one cast strand which laterally departs out of the continuous casting mold through said at least one outlet opening;
said strand guide arrangement for each related cast strand containing two strand guide tracks defining first and second guide tracks curved in opposite directions;
each of said two strand guide tracks having a predetermined radius of curvature and each radius of curvature having a center;
the center of the radius curvature of the first guide track, viewed in the direction of travel of the cast strand, being located below its related first guide track;
the center of the radius of curvature of the second guide track being located above its related second guide tracks;
said continuous casting mold comprises a curved continuous casting mold having a predetermined center of curvature;
and
the center of curvature of one of said two strand guide tracks being located on said side thereof which is opposite to the side of said one of said two strand guide tracks at which there is located said predetermined center of curvature of said continuous casting mold.
