Description

Technical Field

[0001] The utility model relates to the technical field of steel forging, in particular to a molten steel feeding mechanism. Background Art

[0002] During the steel forging process, the molten steel needs to be quickly transported out after hot pressing and cooled down in time during the transportation process.

[0003] At present, the feeding mechanism mostly uses cold water for cooling. A large amount of cold water is directly poured on the surface of the steel billet to quickly take away the heat on its surface. However, a large amount of steam will be generated in the process (the steam also carries a small amount of exhaust gas). The steam will form water vapor when it is cooled in the air, which increases the air humidity in the workshop and accelerates the corrosion process of the workshop equipment. At the same time, a large amount of steam is wasted in the form of water resources.

[0004] To this end, our company has proposed a conveying mechanism that can collect and process steam, which saves water resources and reduces the air humidity in the workshop. Utility Model Content
