A rotary scrap heating system

Abstract

The invention is a rotary scrap steel heating system, which includes a feeding trolley, a baking trolley, a discharging trolley and a rotary furnace, a feeding trolley, a baking trolley and a discharging trolley sliding along the first track, the second track and the third track respectively , the third track is set under the rotary furnace, the first track and the second track are vertically intersected and set on one side of the third track; the scrap steel in the feeding trolley is fed into the rotary furnace through the chute-shaped discharge port, and then the feeding trolley returns In the original position, the baking trolley runs along the track to the entrance of the rotary furnace, and preheats the scrap steel in the rotary furnace. After that, the baking trolley returns to the original position, and the discharging trolley runs to the bottom of the rotary furnace for discharging. Follow this process in a loop. The invention has a simple structure, and the feeding, baking, and discharging do not affect each other, which greatly improves the working efficiency. The scrap steel is preheated while rotating, which effectively improves the preheating efficiency, improves the fuel utilization rate of the baking system, and further realizes energy saving and reduction. consumption.

Description

technical field [0001] The invention belongs to the technical field of heating devices, in particular to a scrap steel preheating system for electric furnace steelmaking, in particular to a rotary scrap steel heating system. Background technique [0002] In the iron and steel production using the intermediate frequency furnace as the smelting furnace, in order to save energy and reduce consumption, it is usually necessary to preheat the scrap steel. The traditional scrap steel preheating system is set in a single form. The heating efficiency is low, the fuel utilization rate is not high, and exhaust gas is exhausted excessively. On the other hand, the traditional preheating device has low working efficiency due to the limitation of the setting form. Contents of the invention [0003] The object of the present invention is to provide a rotary scrap steel heating system in order to overcome the deficiencies of the prior art. Its structure is reasonable, the form is novel, th...

[0002] In the iron and steel production using the intermediate frequency furnace as the smelting furnace, in order to save energy and reduce consumption, it is usually necessary to preheat the scrap steel. The traditional scrap steel preheating system is set in a single form. The heating efficiency is low, the fuel utilization rate is not high, and the waste gas is exhausted excessively. On the other hand, the traditional preheating device has low working efficiency due to the limitation of the setting form.
