Continuous casting method and apparatus thereof

In a slab continuous casting machine comprising a tundish for reserving a molten steel therein, a nozzle holding cassette disposed on an outer bottom portion of the tundish, a mold for use in a casting, and an immersing nozzle mounted in the nozzle holding cassette and for pouring the molten steel in the tundish into the mold, the cavity has a generally rectangular sectional shape defined by a pair of short sides and a pair of long sides. When the immersing nozzle is inserted into the mold and when the immersing nozzle is taken out from the mold, a movement of the immersing nozzle gripped by a handling arm in the mold is limited in a direction parallel to the pair of short sides.

Method and apparatus for continuous casting of a thin slab

An endless track continuous casting machine having a pair of upper and lower endless belts facing each other in a spaced apart relationship and travelling in a downwardly slanted direction which form the long side walls of a mold. Dam blocks continuously and closely disposed and pinched between both side edges of the pair of endless belts and each supported by a link forming part of an endless chain wound around sprockets disposed on each side of the pair of endless belts form the short side walls of the mold. The dam blocks are mounted on each of the links of the endless chain to be movable inwardly and outwardly, and they are guided by a guiding mechanism to a projecting position when entering the advancing path of the mold and are guided to a set back position when entering the returning route. This guiding mechanism is adjustable to change the projected position of each dam block while the endless chain is moving, thus enabling the width of a cast piece to be altered without stopping the casting work.

Endless track continuous casting machine

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.
