A method for precise positioning and installation of converter support ring and furnace shell

Abstract

The invention relates to a method for precise positioning and installation of a converter support ring and a furnace shell. The position of the support point of the converter support ring is accurately determined, and the combined mounting bracket is used to reduce the center of gravity of the equipment to improve the stability of the installation process, and at the same time ensure the positioning accuracy. Point positioning pins make the converter support ring accurately positioned on the support ring support, use the center line of the converter to adjust the center position of the converter mouth, and improve the positioning accuracy with the oxygen lance mouth of the vaporization flue and the center of the oxygen lance. This method avoids the excessive deviation of the positioning pin hole of the bearing seat of the converter support ring, and effectively solves the key technical problems in the precise positioning and installation of the converter support ring and the furnace shell.

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.
