AI Technical Summary

Technical Problem

Existing rebar refining equipment suffers from high energy consumption and inconvenient maintenance in ultra-low nitrogen control, and the multiple drive sources lead to increased production costs.

Method used

The refining unit for rebar with a double-lid structure achieves efficient electrode movement and sealing through the cooperation of lifting and rotating devices. The same lifting device is used to allow the electrodes to enter and leave the ladle, and the furnace cover is cooled by cooling medium to extend its service life.

Benefits of technology

It reduces energy consumption and production costs, extends the service life of the furnace cover and its accessories, and improves production efficiency and ease of maintenance.

Abstract

This invention relates to the field of rebar refining technology and discloses a rebar refining apparatus based on ultra-low nitrogen control. The apparatus includes a ladle, with a lifting device and a rotating device arranged on the outside of the ladle. The lifting device is mounted on the rotating component of the rotating device. A furnace cover body is mounted on the top of the ladle, and a gear is connected to one side of the furnace cover body. An outer furnace cover is positioned above the furnace cover body, and the outer side of the outer furnace cover is connected to the moving end of the lifting device. A drive gear is mounted on the outer side of the outer furnace cover, meshing with the gear. A bracket is also connected to the moving end of the lifting device, and a transmission assembly is mounted on the bracket. A gear set is arranged on the outside of the transmission assembly. This invention, by setting up a double cover and cooperating with different transmission assemblies, can achieve the effect of the electrode entering the ladle only after the ladle is sealed, and the electrode leaving the furnace cover before it is opened, thereby reducing energy consumption and production costs.
