Pushing segmented hydraulic synchronous lifting assembling method for furnace shell of blast furnace

Abstract

The patented technology is mainly used for achieving the problems that an industrial system blast furnace is pushed for replacement of a furnace body, when a blast furnace body structure is pushed forrapid replacement of the new furnace body, the structural stability of a blast furnace body framework structure is not affected to the largest degree, structure detachment is reduced for pushing thefurnace body, and the replacement time is saved. A method is suitable for overhauls and replacement of the furnace body structure of the high-capacity blast furnace, and the problems that the replacement period of the furnace shell of the blast furnace is long, and the idling period is long are solved.

Description

technical field [0001] The invention relates to the technical field of blast furnace construction, in particular to a blast furnace shell pushing segmental hydraulic synchronous lifting assembly method. Background technique [0002] With the development of modern industry, equipment is developing toward large-scale, high-efficiency, and low-energy consumption. The volume of the blast furnace is also getting bigger and bigger, but the blast furnace body is continuously operated at high temperature, and the furnace body structure and equipment life are relatively short. The traditional method is generally to repair and replace the blast furnace in different parts, and some blast furnaces are moved offline to replace the furnace body structure, but the traditional replacement method has a long shutdown time and partial maintenance, which has a great impact on production. The method of moving and replacing the furnace body structure off-line needs to destroy part of the main bo...

Problems solved by technology

The volume of the blast furnace is also getting bigger and bigger, but the blast furnace body is continuously operated at high temperature, and the furnace body structure and equipment life are relatively short. The traditional method is generally to repair and replace the blast furnace in different parts, and some blast furnaces are moved offline to replace the furnace body structure, but the traditional replacement method takes a long time to shut down the furnace and carry out partial maintenance, which has a great impact on production

The method of moving and replacing the furnace body structure off-line needs to destroy part of the main body frame structure beam, which affects the stability of the main structure, and repairing the frame structure beam at high altitude poses a great safety hazard
