Loop type continuous metal casting machine

Abstract

Herein disclosed is a loop type continuous metal casting machine in which two side dams are revolved in a loop passing along a casting zone from the entrance end thereof between upper and lower endless revolving casting belts to define a downhill moving mold and in which each of the side dams is formed of a multiplicity of metal dam blocks so strung onto a flexible metal strap loop that the metal dam blocks abut in end-to-end relationship against one another but are allowed to slide on and relative to the metal strap loop. Push means is disposed near the entrance end of the casting zone and is reciprocated back and forth in synchronism with the passage of each side dam for periodically entering the wedge-shaped gap, which is formed between the adjacent two of the metal damblocks of the corresponding side dam loop before entry into the casting zone, to push the preceding one of the adjacent two forward thereby to tightly press the preceding damblocks together so that the end-to-end abutting relationships of the damblocks may be ensured while the side dam loops are passing through the casting zone. Thus, molten metal can be continuously cast in the moving mold without burrs.
