Abstract

The invention discloses an integral hydraulic jacking inverted construction method of a large converter, comprising the following steps: 1) in an additive bay, fixedly installing a converter shell bracket and an integral bracket on a ladle car, and building an erecting stage on the integral bracket; 2) successively inverting and hoisting the welded converter shell and backing ring which are welded into a whole on the converter shell bracket and the integral bracket, respectively adjusting the positions of the converter shell and the backing ring by a hydraulic jack to cause the relative positions of the converter shell and the backing ring to satisfy a design requirement, and ensuring that a center elevation is bigger than a designed elevation; 3) installing and hanging; 4) moving the ladle car to transport the converter to the base of the converter, finishing installation of a trunnion bearing pedestal before transporting; and 5) lowering the backing ring to cause the bearing pedestal to land on the base, and fixing after adjusting. In the invention, the phenomenon that the additive bay of a converter workshop uses a large crane is avoided, a jack is adopted to adjust the positions of the backing ring and the converter shell, and construction is convenient. The converter is assembled in the mode that the backing ring and the converter shell are inverted, and hoisting and welding are easy to operate.

Description

technical field [0001] The invention relates to an installation method of steelmaking equipment, in particular to a construction method of hydraulic jacking and inversion construction of a large-scale converter as a whole. Background technique [0002] The main body of the converter is mainly composed of supporting rings, furnace shells, suspensions, trunnion supports and tilting devices. The components are bulky, heavy, complex in structure and require high installation accuracy. The main difficulties in installation and construction are: [0003] 1. There is no large crown crane across the furnace in the converter workshop, and the installation site is narrow, and there is no working space for lifting equipment such as large cranes. [0004] 2. The main components of the converter body are bulky and heavy, and it is difficult to control the installation accuracy. [0005] 3. The gap between the horizontal suspension, the support ring and the furnace shell is narrow, and ...
