Abstract

The invention discloses a rotating furnace scrap steel feeding hopper, and belongs to the technical field of iron and steel smelting. The rotating furnace scrap steel feeding hopper comprises a box, four groups of lifting lugs and one group of reinforcing ribs, a discharging port is formed in the front end of the box, the reinforcing ribs are arranged outside two side walls of the box, and the lifting lugs are symmetrically and fixedly mounted on the front, the rear, the left and the right of the reinforcing ribs. The hopper is characterized in that one row of rollers are arranged at the bottom of the box and perpendicular to a center axis of the length direction of the bottom surface of the box, and one group of gears are arranged on the outer wall of first roller positioned at the discharging port of the box along a peripheral direction. The hopper solves the problem that scrap steel materials are stacked on a furnace opening in the feeding process, feeding smoothness of scrap steelis improved, and the feeding proportion of the scrap steel is increased.

Description

technical field [0001] The invention relates to a feeding hopper, in particular to a scrap steel feeding hopper for converter steelmaking, which belongs to the technical field of iron and steel smelting. Background technique [0002] Steel scrap is a clean resource compared to ore, which can be used indefinitely. Compared with producing steel with ore and coking coal, increasing the amount of steel scrap used in the steelmaking process can greatly save energy and water, and reduce waste gas, waste water, and waste residues. emissions and reduce environmental pollution; in addition, with the continuous increase in the accumulation of steel in society, the price advantage of scrap steel over hot metal is prominent, and this trend will continue for a long time. Therefore, after increasing the proportion of scrap steel into the furnace, the economic and social benefits will be significantly improved, which is of great significance to enhance the competitiveness of enterprises. ...
