Problems solved by technology

However, the known installation methods of these two steelmaking converters are to use cranes and wire ropes to hoist the furnace shell as a whole or in sections. The disadvantages are that they are restricted by the external environment and have an impact on the construction period of the converter installation and the entire steelmaking construction period. Great, and there is a security risk
[0003] Therefore, there are above-mentioned inconveniences and problems in the known extra-large converter shell hoisting method

Embodiment 1

[0038] The overall hoisting method of the super-large converter shell of the present invention comprises the following steps:

[0039] a. The overall hoisting scheme of the converter shell is determined.

[0040] (1) Carry out a comprehensive evaluation of the two known converter installation methods of "trolley jacking method" and "converter sliding method", and select the overall hoisting method of the converter shell that is suitable for the site environment and construction period.

[0041] (2) Hoisting load calculation: measure and calculate the installation elevation of the metallurgical bridge crane track, the center elevation of the balance beam shaft sleeve of the bridge crane and the maximum lifting elevation at the bottom of the converter shell, select a suitable heavy metallurgical bridge crane, and confirm that the heavy metallurgical bridge crane The lifting capacity of the crane is greater than the weight of the converter shell, which can meet the overall hoisti...

Abstract

A method for overall hoisting of a super-large converter shell, which is characterized in that it includes the following steps: a. determining the overall hoisting scheme of the converter shell; b. refitting a heavy metallurgical bridge crane; c. making two sets of hoisting supports; d. installing two set of hoisting supports, e, calculate the distance between the lower surface of the furnace shell and the upper surface of the supporting ring, f, hoist the converter shell as a whole into the supporting ring, and complete the overall hoisting of the extra-large converter shell. The overall hoisting method of the super-large converter shell of the present invention has the advantages of scientific and reasonable design of the overall hoisting steps of the converter shell, strong operability, safe and reliable hoisting engineering quality, and the realization of a 480t / 80t heavy-duty metallurgical bridge crane. The overall hoisting of the seat to the furnace shell reduces a large number of construction measures, reduces engineering costs and has the advantages of significant economic effects.

Description

technical field [0001] The invention relates to a method for hoisting a converter, in particular to an overall hoisting method for an extra-large converter shell. Background technique [0002] In the steelmaking project, the installation methods of the steelmaking converter mainly include "trolley jacking method" and "converter sliding method". In the "trolley jacking method", since the furnace front platform is not installed, the converter The furnace shell can be hoisted as a whole by a heavy-duty metallurgical bridge crane with a feeding span and a steel wire rope, and installed on the pre-made tire frame. In this case, it is not necessary to calculate the height of the converter shell and the limit lifting of the heavy metallurgical bridge crane high. In the "converter sliding method", part of the frame of the furnace front platform is not installed. After the supporting ring is hoisted to the sliding beam, the converter shell is hoisted in sections by using a heavy-dut...
