Description

Technical Field

[0001] The utility model relates to steelmaking equipment, in particular to a device for adding a steelmaking drainage agent. Background Art

[0002] With the development of steel technology, the requirements for production automation are becoming more and more comprehensive. The ladle for steelmaking mainly adopts the drainage method of slide casting. The addition method of drainage agent is an important link. The drainage agent is mainly packaged in plastic woven bags. The usual woven bag packaging is cut by a sharp knife in the funnel, close contact with the discharge port, and the drainage agent is put into the water inlet hole. It is time-consuming and labor-intensive, not environmentally friendly, and not only threatens the personal safety of the operator, but also the weight of the added drainage agent is not accurate. The shape of the drainage agent after addition is irregular, which affects the product quality and is not conducive to the self-casting of molten steel. After each discharge hopper of the existing drainage agent adding device works, the rising feeding direction is unstable, and manual intervention is required to rotate the hopper so that the feeding port direction is used for feeding, and each feeding requires manual feeding.
