Steel scrap adding device for blast furnace and adding method thereof

Abstract

The invention provides a steel scrap adding device for a blast furnace and an adding method thereof. The steel scrap adding device for the blast furnace comprises a material receiving mechanism, a weighing mechanism and a conveying belt, wherein the material receiving mechanism comprises a material receiving hopper and a feeding machine, the weighing mechanism is used for weighing steel scrap conveyed to the weighing mechanism by the material receiving mechanism, and comprises a weighing hopper, a metering device and an opening and closing device, the conveying belt comprises a material receiving belt and a feeding belt, the feeding machine continuously and uniformly distributes the steel scrap on the material receiving belt, and then conveys the steel scrap to the weighing mechanism, andthe steel scrap flows out from an opening and closing position of the opening and closing device, is conveyed onto a feeding main belt of the blast furnace through the feeding belt, and then is transported into the blast furnace. The steel scrap adding device for the blast furnace is simple, easy to operate, high in automatic degree and efficient in running. The material receiving hopper and the weighing hopper are self-made devices, and all the other auxiliary tools can utilize used tools, and furthermore the conveying belt is a sintering or blast furnace feeding used material, and thereforemanufacture cost is low.

Description

technical field [0001] The invention belongs to the technical field of smelting, and in particular relates to a scrap steel adding device and adding method for a blast furnace. Background technique [0002] The recycling of scrap steel is usually used in steelmaking production, but the recycling of scrap steel has disadvantages such as low recovery rate, high energy consumption, large heat loss, and smoke pollution. In recent years, relevant domestic technical workers have been working hard to expand the utilization of scrap steel Adding steel scrap to the blast furnace for ironmaking is a useful way to try. Scrap steel is the steel scrap that does not become a product in the production process of the iron and steel plant and the steel materials in the equipment and components that are scrapped after use. Among them, the steel is called scrap steel, and the pig iron is called scrap iron. They are collectively called scrap steel. Scrap steel is mainly divided into It is divi...
