Description

Technical Field

[0001] This utility model relates to a bag baking device, and more particularly to a bag baking device for die-cast steel ladles. Background Technology

[0002] A ladle baking machine is a device used to bake steel ladles, which are generally required to be baked after they are newly built and before they are filled with molten steel. It is also called a ladle baking machine.

[0003] Since the baking part is generally located on a cover plate, this results in a relatively large weight for the cover plate. Therefore, some existing technologies use a lifting structure for the cover plate. For example, patent application number 202222785501.8 discloses a mobile vertical lifting baking device. Its technical solution includes: a base and a moving plate. A lifting frame is installed on one side of the top of the base. A lifting plate is installed on the inner surface of the lifting frame via a sliding groove. A cover plate is installed on the middle of one side of the lifting plate via a support frame. A gas pipe is installed in the middle of the top of the cover plate. A nozzle is installed at the bottom of the gas pipe on the lower surface of the cover plate. A positioning column is installed on the top of the base near the lifting frame. A connecting plate is installed on the outer surface of the positioning column via a bearing. A moving plate is installed on one side of the connecting plate. Universal wheels are installed at the four corners of the lower surface of the moving plate. The mobile vertical lifting baking device solves the problem that existing devices often use fixed steel ladle placement platforms, making them immobile. When forklifts load materials, the ladle oven is easily damaged by collisions, affecting its service life. This improves the convenience of loading and unloading steel ladles, thereby ensuring the service life of the baking device.

[0004] However, the aforementioned patent uses wheels and a moving plate to move the ladle. First, the addition of metal blocks to the ladle significantly increases its mass, making it difficult to move. Furthermore, the excessive inertia during movement makes it hard to stop. In addition, since the ladle needs to be closed with the cover plate before baking, the position of the ladle is extremely important. The use of wheels means that after the ladle moves to the vicinity of the cover plate, it needs to be kept vertical and positioned horizontally. Positioning wastes a lot of time and affects the baking efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, which makes it inconvenient to move the steel ladle by a single wheel and requires positioning after movement, thus affecting efficiency, this utility model provides a ladle baking device for die-casting steel ladles.
