Quick feeding device for feeding waste steel into electric furnace and feeding method thereof

Abstract

Disclosed are a rapid feeding device and a feeding method for feeding scrap steel into an electrical furnace. The rapid feeding device comprises a high temperature coupling tank (10) in communication with the electrical furnace, and a cold material-receiving device for feeding in the scrap steel. The cold material-receiving device comprises a long feeding groove (2) that can be hoisted. The long feeding groove (2) has a discharge port (2a) made at its front end, that can be in sealed communication with a feeding port of the high temperature coupling tank (10). The rapid feeding device has good air tightness and a high feeding speed. The feeding is carried out in closed conditions, which can effectively reduce air leakage, and improve the performance of the electrical furnace dedusting system. The discharge port is made at the front end of the long feeding groove so that the thickness of the spread material can be easily controlled.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a feeding device of an electric furnace smelting device and a feeding method thereof. Background technique [0002] Electric furnace smelting is an important steelmaking method. During the smelting process, the link of raw materials added to the electric furnace directly affects the production environment and power consumption. The most typical and common method in electric furnace production is that the material basket directly feeds the furnace hall, but the production environment is extremely In order to improve the production environment and reduce power consumption, a technology of rapid airtight feeding into the electric furnace has emerged. This technology is a technology for energy saving, consumption reduction and environmental protection in the production of electric furnaces. [0003] When feeding some raw materials, it is very difficult to implement th...

AI Technical Summary

Problems solved by technology

The main problems of the above technology are: the reliability of opening the bottom door of the long bottom opening tank is low, there are high probability events that affect the production efficiency, there is one more production link for feeding the long feeding tank, and the thickness of the material in the feeding long tank It is not easy to control, which will affect the subsequent conveying and processing of scrap steel, and will have an adverse effect on the impact of long tank materials.
