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

Abstract

The invention discloses a quick feeding device for feeding waste steel into an electric furnace. The device comprises a high-temperature connecting tank and a cold receiving material conveying device, wherein the high-temperature connecting tank is communicated with the electric furnace; the cold receiving material conveying device is used for loading the waste steel and comprises a feeding long tank which can be lifted to move; and the front end of the feeding long tank is provided with a discharge port which is hermetically communicated with a feed port of the high-temperature connecting tank. The device has a simple structure, is convenient to manufacture and easy and convenient to operate, has a good airtight effect, high reliability and high feeding speed, is environment-friendly andis convenient for maintenance of an entire system. In addition, a feeding process is performed under a sealed condition, so that air leakage can be effectively reduced, efficacy of a dust removing system of the electric furnace is improved, and a production environment is greatly improved; meanwhile, due to airtight production of the electric furnace, heat loss of a furnace body during productionof the electric furnace is also reduced and energy is saved. Compared with the prior art, feeding into the feeding long tank by using a bottom open type material tank is avoided, thickness of a laid material can be easily mastered and subsequent production can be facilitated, and the feeding long tank can be prevented from being damaged due to impact of the waste steel.

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 the...

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.
