Converter trunnion ring and method for accurately positioning and installing converter shell

Abstract

The invention relates to a converter trunnion ring and a method for accurately positioning and installing a converter shell. The method accurately determines the position of a supporting point of the converter trunnion ring, adopts a combined mounting bracket to reduce the center of gravity of equipment, improves the stability of the mounting process, ensures the positioning accuracy, and adopts a supporting point positioning pin to accurately position the converter trunnion ring on a trunnion ring bracket, and the central position of a converter mouth is adjusted by using the central line of a converter, so that the positioning precision of an oxygen lance opening and the oxygen lance center of a vaporization flue is improved. According to the method of the invention, excessive deviation of a positioning pin hole of a converter trunnion ring bearing pedestal is avoided, and the key technical problem in accurate positioning and mounting of the converter trunnion ring and the converter shell is effectively solved.

Description

technical field [0001] The invention relates to the technical field of steelmaking equipment installation, in particular to a method for precise positioning and installation of a converter support ring and a furnace shell. Background technique [0002] When installing the converter support ring and the converter shell in the traditional converter installation, due to the large size of the equipment and the heavy weight above the installation bracket, the center position of the equipment will be deviated due to the influence of hoisting factors and unstable driving factors. After it is in place, the positioning pin hole of the bearing seat of the converter support ring deviates greatly, and it is difficult to adjust the converter support ring. After the converter shell is installed in place, the positioning accuracy of the center of the converter mouth and the mouth of the oxygen lance of the converter vaporization flue and the center of the oxygen lance is high. The existing...

[0002] When installing the converter support ring and the converter shell in the traditional converter installation, due to the large size of the equipment and the heavy weight above the installation bracket, the center position of the equipment will be deviated due to factors such as hoisting and driving instability. After being in place, the positioning pin hole of the bearing seat of the converter support ring is deviated greatly, and it is difficult to adjust the converter support ring

After the converter shell is installed in place, the positioning accuracy of the center of the converter mouth and the mouth of the oxygen lance of the converter vaporization flue and the center of the oxygen lance is high. The existing installation technology cannot well meet the accuracy requirements of the concentricity of the converter mouth and other equipment.
