Edge-driving top-blown converter

Abstract

The invention relates to an edge-driving top-blown converter. The edge-driving top-blown converter comprises a converter body and a rotation power source which are arranged on a machine frame. An axial riding wheel and top pillars are arranged in the axial direction of the machine frame, and radial riding wheels are arranged in the radial direction of the machine frame. In addition, the machine frame is flexibly connected with a converter body bracket ring. Rolling rings are arranged on the upper ring face and the lower ring face of the converter body bracket ring respectively. A tooth ring is arranged in the middle of the converter body bracket ring. One end of the tooth ring is engaged with a gear. The gear is connected with the rotation power source. A tipping supporting shaft is arranged in the machine frame. The two ends of the tipping supporting shaft are fixed to an equipment foundation through support seats, and one end of the tipping supporting shaft is connected with a tipping reduction box provided with a tipping power source. The edge-driving top-blown converter is compact in structure, safe and reliable, and the purpose for accurately controlling the rotation speed of a converter body is achieved.

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 clamp the furnace body to make a 360o tilt 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 to meet 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 world mainly h...

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
