Embodiment approach

[0030] (1) Sliding of converter shell 1:

[0031] according to figure 1 It can be seen that before the converter shell 1 slides in place, the platform beams and columns of the 8m platform cannot be installed. The furnace shell slideway 4 is set on the ±0.00m platform, and the furnace shell slideway 4 adopts two I600mm I-beams, the length of which is from the feeding span ( figure 1 Middle G-H span) middle to converter span ( figure 1 Middle 1 / F-G span) the edge of the converter foundation 6, the distance between the two I-beams is determined according to the size of the converter shell 1, and grease is applied on the surface of the slideway to reduce frictional resistance. A furnace shell traction device 5 is installed on the platform of ±0.00m, and the furnace shell traction device 5 is composed of a hoist and a pulley block, and is used for traction of the converter shell 1 .

[0032] Rotate the converter shell 1 by 180° with the feeding trolley 2, make the bottom of the ...

Abstract

The invention discloses a method for inversely mounting a revolving furnace through a winch, and belongs to the technical field of steel-making mechanical equipment. The method comprises processing steps of slipping of a revolving furnace shell, arranging of a revolving furnace and supporting ring lifting device, slipping and mounting of a supporting ring, lifting of a revolving furnace shell, connecting and assembling of the revolving furnace shell and the supporting ring, and dismounting of traction and lifting devices of all platforms. The method is suitable for engineering of expansion. overhauling and new construction of the revolving furnace and the engineering with the late approach time of the revolving furnace and supporting ring lifting device; an existing crown block and an existing workshop structure are used, a revolving furnace system device is mounted only through the winch and a pulley set, mechanical one-shift cost and manual cost of a large crane are saved, and mounting safety and reliability of the revolving furnace system are improved.

Description

technical field [0001] The invention belongs to the technical field of installation of steelmaking machinery and equipment, and in particular relates to a method for installing a converter upside down by a winch. The converter shell and support ring are installed upside down by the winch for traction and lifting. Background technique [0002] In the construction of steelmaking projects, the converter system is the core of the entire steelmaking project. The installation of converter equipment is a key process, and the installation period is long. In recent years, more and more large-scale converters (300t and above) have been used. The weight of the equipment is large and the installation accuracy is high. However, the crown crane of the converter span is not enough to directly hoist the converter shell, supporting ring and other equipment in place. [0003] In the past steelmaking engineering construction, the installation of converter equipment mainly adopts the followin...
