Abstract

The invention relates to the field of metallurgical buildings, in particular to a method for integrally hoisting and replacing a pivotal bearing from a large ladle rotary table upper device of a continuous casting machine. The method is characterized by comprising the steps of 1, determination of three-party power-cut; 2, dismantling of a peripheral unit of a rotary body; 3, dismantling of an internal unit of the rotary body; 4, dismantling of an upper unit of the rotary body; 5, installation of a lifting tool; 6, integral hoisting and shifting-out of the rotary body and the upper unit; 7, replacement of the pivotal bearing; 8, restoration of the rotary body and outer ring bolt screwing; 9, dismantling of the lifting tool; 10, restoration of other units and pipelines; and 11, debugging. Through the method, it is ensured that the worn continuous casting large ladle rotary table pivotal bearing is quickly replaced within a very short period of time, the integrity of equipment is effectively ensured, the dismantling and reconstruction installation work amount is greatly reduced, the construction period is effectively shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of metallurgical construction, in particular to a method for integrally hoisting and replacing the slewing bearing of the upper equipment of the ladle slewing table of the continuous casting machine. Background technique [0002] Continuous casting technology has significant advantages such as greatly improving metal yield and slab quality, saving energy and reducing consumption, and has been widely adopted by iron and steel enterprises. The slab continuous casting machine is mainly composed of a casting system and a casting stream system, and is the core equipment of the ladle rotary table casting system. Due to the long-term high-temperature operation, it is necessary to maintain the bale turntable regularly. Rotary table bearings are easy to wear and wear parts and need to be replaced regularly. In order to reduce the impact on the production line, it must be completed quickly during the overhaul of the production...
