Screening device for metallurgical furnace burdens

Abstract

The invention discloses a screening device for metallurgical furnace burdens. The screening device comprises a furnace burden pulverizer, a conical pulverizing bin, a feed conveying belt and a discharge conveying belt; the furnace burden pulverizer is arranged at a middle position in the conical pulverizing bin; the feed conveying belt is connected with an entrance at the upper end of the conicalpulverizing bin; the discharge conveying belt is connected with an exit at the lower end of the conical pulverizing bin; a drawer-type vibrating screen is arranged in the conical pulverizing bin; andthe drawer-type vibrating screen is arranged at the lower part of the furnace burden pulverizer. According to the screening device, the metallurgical furnace burdens are pulverized and screened beforebeing added into a metallurgical furnace, thereby guaranteeing the size uniformity and stability of the metallurgical furnace burdens, thus guaranteeing that efficient and sufficient reaction can berealized after the furnace burdens are added into the metallurgical furnace, and accordingly the stability and controllability of the quality of a steel smelting process are guaranteed, and the quality of smelted steel is promoted.

Description

technical field [0001] The invention belongs to the field of iron and steel smelting equipment, in particular to a screening device for metallurgical charge. Background technique [0002] The raw and auxiliary materials in iron and steel smelting production are referred to as metallurgical charge for short. It usually contains iron ore, steel scrap, pig iron, coke, ferroalloys, etc. At the same time, as an auxiliary product in steelmaking, metallurgical charge is an important additive in the steelmaking process. In the entire steelmaking process, oxygen from different sources is used to oxidize the complex metals contained in the charge, and various complex processes are adopted. Make good use of metallurgical charge to remove silicon, phosphorus, carbon, deoxidation and alloys, etc. [0003] In the actual production process, the size of the metallurgical charge is different. For the large-sized metallurgical charge, it is difficult to fully and efficiently contact the ste...
