An edge-driven top-blown converter

Abstract

The invention relates to an edge-driven top-blown converter, which comprises a furnace body and a rotary power source respectively placed on a frame. The frame is provided with an axial supporting wheel and a supporting column along the axial direction, and a radial supporting wheel is provided along the radial direction, and is flexibly connected with a furnace body bracket ring; the upper and lower rings of the furnace body bracket ring Rolling rings are arranged on the surface respectively, and a ring gear is arranged in the middle, and a gear is meshed at one end of the ring gear; the gear is connected to the rotary power source; a tilting support shaft is provided in the frame, and the tilting support Both ends of the shaft are respectively fixed on the equipment foundation through supports, and one end is connected with a tilting reducer with a tilting power source. The invention has the advantages of compact structure, safety and reliability, and achieves the purpose of precisely controlling the rotating speed of the furnace body.

Description

technical field [0001] The invention relates to a smelting furnace in the nonferrous metallurgy industry, in particular to an edge-driven top-blown converter (also known as an oxygen oblique-blown rotary converter). Background technique [0002] The top-blown converter (also known as the oxygen oblique-blown rotary converter) is composed of a furnace body, a clamping mechanism, a tilting system, and a rotary drive system. The clamping mechanism can hold the furnace body and tilt it 360º at a speed of 0~1.0rpm; when the furnace body is tilted to a working angle of 28º with the horizontal angle, the rotary drive system drives the furnace body, and rotates according to the requirements of the smelting process. The longitudinal axis rotates at a certain speed, and the range of rotation speed is 0.5~18rpm, so as to complete the smelting process of the material. [0003] At present, the top-blown converter (also known as oxygen oblique-blown rotary converter) rotary drive in the ...

AI Technical Summary

Problems solved by technology

[0009] This type of bottom drive equipment has large dimensions. Although it has low energy consumption, high efficiency, and long service life of spare parts (radial support rollers, rolling rings), its structure determines that when replacing the furnace body or axial support rollers, radial For spare parts such as support rollers and rolling rings, it is cumbersome to adjust the coaxiality of the bottom drive shaft and the furnace body, and the adjustment takes a long time; the bottom of the furnace body is designed with a rotary drive system. , the 360° tilting of the furnace body cannot be truly realized; when the hydraulic motor at the bottom fails, the whole equipment cannot be produced normally
