[0002] Converter smelting is a very important process in the steelmaking process, and the converter tapping rate is an important technical and economic indicator in converter smelting. Its control level directly affects the production efficiency of steelmaking, the quality of molten steel and the production cost of the steel plant. Among them, the most influential factor is the stability of the converter charging amount. Scrap steel includes pig iron blocks and briquette scrap steel, and their chemical compositions are different. According to the actual situation of the molten iron composition in the furnace, the structural composition and charging amount of pig iron blocks and briquette scrap steel are adjusted to achieve the stability of the molten iron composition and the stability of the converter charging amount, and improve the converter tapping rate.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN215974623U discloses a new type of scrap steel proportioning device. It includes a gantry, an electromagnetic hoist, a connecting fixture, a guide rail, a supporting mechanism and a positioning mechanism, wherein the supporting mechanism includes an outer sleeve, the bottom end of the outer sleeve is fixedly connected with a triangular support foot, the upper surface of the electromagnetic hoist is located at the bottom end of the outer sleeve and is fixedly connected with a support foot limiting cylinder, the bottom end of the triangular support foot is sleeved with the top end of the support foot limiting cylinder, the top end of the outer sleeve is limitedly engaged with an inner sleeve, and the top end of the inner sleeve is fixedly connected with the bottom end of the connecting fixture. The new type of scrap steel proportioning device provided by the utility model has the following characteristics: through the design of the triangular support foot and the support foot limiting cylinder, it is convenient to limit the position of the electromagnetic hoist, so that the electromagnetic hoist can be more stable and balanced during the lifting process, and the problem of the electromagnetic hoist tilting to one side is avoided. Through the sleeve connection between the inner sleeve and the outer sleeve, the distance between the inner sleeve and the outer sleeve can be adjusted according to the length of the zipper.

[0004] The existing pig iron and scrap steel proportioning equipment cannot mix the pig iron blocks and the briquette scrap steel, which makes the components of the molten iron in the furnace different after entering the converter. At the same time, the existing scrap steel proportioning is generally carried out by weighing, which requires two weighings, and before the second weighing, it is necessary to calculate based on the first weighing data to ensure the proportion, which is very inconvenient.
