AI Technical Summary

Technical Problem

Existing technologies fail to effectively remove lightweight foreign matter mixed in with scrap steel when adding it, resulting in intense melting reactions in the electric arc furnace, emitting dense smoke, and affecting the production environment.

Method used

A first cover and a second cover are set around the vibrating material device. A first fan blows air to remove light foreign objects from the material on the upper part of the conveying platform and collects them using a negative pressure collection box. A second fan blows air away from the material conveying direction to prevent foreign objects from entering the electric arc furnace. The combination of a temporary storage area and a feeding conveying area improves the material feeding efficiency.

Benefits of technology

It effectively removes light foreign matter, reduces the reaction intensity of the electric arc furnace, improves the production environment, and increases the feeding efficiency of scrap steel.

Abstract

This invention belongs to the technical field of steel casting equipment, specifically relating to a high-efficiency feeding system for an electric arc furnace. It includes several vibrating devices connected end-to-end, with the tail end of each vibrating device connected to the electric arc furnace. Each vibrating device has a conveying platform at its upper end, and each conveying platform is equipped with a first fan and a second fan. It also includes a first cover and a second cover connected in sequence, covering the outer periphery of the vibrating devices. The first fan and the second fan are respectively connected to the inner sides of the first cover and the second cover. A negative pressure collection box is located outside the vibrating devices and connected to the first cover. This invention solves the problem in existing feeding equipment where lightweight foreign matter mixed in with scrap steel is not pre-removed, resulting in intense melting and reaction of the material in the electric arc furnace, emitting dense smoke and adversely affecting the production environment.
