Technical Field

[0001] The utility model belongs to the technical field of raw material mixing, and more specifically relates to a raw material proportioning and mixing device for producing high-performance steel. Background Art

[0002] Steelmaking is the process of mixing various raw materials in a certain proportion to produce steel. In steelmaking production, the correct raw material ratio is very important, which is related to a series of issues such as product quality, production efficiency and energy consumption. The correct raw material ratio can improve product quality, reduce costs, improve production efficiency and other benefits. Therefore, in steelmaking production, it is necessary to pay attention to the scientific rationality of the raw material ratio, so as to ensure the continuous stability and orderliness of steelmaking production. The existing raw material ratio mixing device for high-performance steel production uses a stirring device to mix the raw materials. Since the stirring cannot play the role of up and down flipping, the weight of various materials in the raw materials is different, and the heavy ones are easy to settle at the bottom, resulting in uneven mixing. Therefore, a raw material ratio mixing device for high-performance steel production is proposed. Utility Model Content
