Auxiliary rotating device for steelmaking converter and using method

Abstract

The invention relates to the technical field of converter steelmaking auxiliary equipment, and provides an auxiliary rotating device for a steelmaking converter and a using method. The auxiliary rotating device comprises a support used for supporting the converter, and further comprises a driving mechanism; the driving mechanism comprises a first connecting rod, one end of the first connecting rod is hinged to the converter, the other end of the first connecting rod moves linearly, and a strip hole is formed in the first connecting rod; a first supporting seat is arranged on one side of the first connecting rod, and a sliding groove is formed in the first supporting seat; a first sliding block is slidably arranged in the sliding groove, and a rotating rod is arranged on the first sliding block and arranged in the strip hole in a penetrating mode; a spring is arranged in the sliding groove, one end of the spring is connected with the first sliding block, and the other end of the spring is connected with the bottom of the sliding groove; a first telescopic piece is arranged at the top of the first supporting seat and located above the sliding groove, the first telescopic piece is provided with a first pushing jacking end, and the first pushing jacking end abuts against the first sliding block; and a second telescopic piece is provided with a second pushing jacking end, and the second pushing jacking end is connected with the first connecting rod. According to the technical scheme, the problem that the steelmaking cost is high due to the fact that a large-torque speed reducer is needed for rotation of the converter in the related technology is solved.

Description

technical field [0001] The invention relates to the technical field of converter steelmaking auxiliary equipment, in particular to an auxiliary rotating device for a steelmaking converter and a method for using it. Background technique [0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials. The steelmaking process is completed in the converter by the physical heat of the molten iron itself and the heat generated by the chemical reaction between the components of the molten iron without the aid of external energy. Basic oxygen top-blown and top-bottom compound-blown converters are the most commonly used steelmaking equipment due to their fast production speed, large output, high single furnace output, low cost, and low investment. The converter is generally pear-shaped. When injecting molten iron at 1300°C, the converter needs to lie flat, and then stand up. Oxygen or air is poured into the converter from the top or side to star...
