Description

Guiding device for an automated strand casting system

Technical Field

The utility model relates to a guiding device of a casting machine especially relates to a guiding device that is used for automatic continuous casting billet casting equipment.

Background

Continuous casting machines are widely used for manufacturing continuous cast slabs. In the prior art, a continuous casting machine can manufacture molten steel into a continuous casting billet with a certain thickness by the procedures of crystallization, shaping, cutting and the like. However, in the prior art, when the continuous casting machine works, a certain amount of workers are needed to participate so as to ensure the normal work of the continuous casting machine. Particularly when transporting molten steel to a pouring location, workers are often required to load the molten steel onto a ladle transport mechanism (e.g., a butterfly ladle turret) using a traveling crane.

After the molten steel is crystallized in the crystallizing device, the molten steel is guided to the cutting device by a guide mechanism, and the guide mechanism is generally arranged in a vertical shape in the prior art, so that the steel section semi-finished product formed by crystallization of the crystallizing device is easier to form a regular shape in the subsequent cutting process. However, since the semifinished steel segment crystallized by the crystallizing device requires cooling and further shaping when it is transported to the cutting device, the quality of the subsequent strand is impaired if the vertical guide means is too short. However, if it is too long, the height in the vertical direction tends to be increased, and the space of the entire plant tends to be crowded.
