Abstract

The invention discloses a direct hopper baking device for scrap steel. The direct hopper baking device comprises a combined burner turning cover, wherein a valve is arranged below the combined burner turning cover; a lifting connecting rod is arranged on one side of the valve; a gas pipeline is mounted on one side of the combined burner turning cover; a fan pipeline is mounted at the lower end of the gas pipeline; a combustion-supporting air valve is arranged below the fan pipeline; a high-pressure fan is arranged at the lower end of the combustion-supporting air valve; a lifting motor is arranged on one side of the lifting connecting rod; a scrap steel containing hopper is arranged below the combined burner turning cover; a steel cable is connected to the upper portion of the lifting motor; and a burning torch gas pipeline is arranged on one side of the steel cable. According to the direct hopper baking device, by means of the combination of a main burner gas pipeline, a main burner and the scrap steel containing hopper, scrap steel can be directly baked without kiln baking equipment, the baking time is shortened, the turnover frequency after kiln baking of the scrap steel is omitted, time is saved, cooling of the baked scrap steel is reduced, energy is saved, the steelmaking period is shortened, and the smelting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of scrap iron baking, in particular to a scrap iron direct hopper baking device. Background technique [0002] Scrap steel heating device: It is a special equipment for heating scrap steel in the process of steelmaking production. It consists of a frame, a heating cover, a winch, a rotary connection mechanism, a hollow shaft, a high-pressure fan, a gas delivery system, a burner, a combustion adjustment system, a nitrogen purging system, and a safety detection system. This equipment adopts a winch transmission tilting mechanism, and the tilting angle About 80°, the rotating main shaft (that is, the hollow rotating shaft) is welded together with the pipeline, supported on the bearing seat on the frame, and the heating cover is installed on the top of the protruding combustion arm tube, and the burners are evenly distributed on the heating cover. Drive the crank at the rear of the rotating shaft to drive the c...
