Special construction scheme for hoisting granulation tower for blast furnace project slag treatment engineering

Abstract

The invention relates to a special construction scheme for hoisting a granulation tower for blast furnace project slag treatment engineering, which comprises the following procedures: a procedure of equipping equipment before hoisting, performing technical disclosure work, knowing the structural condition of the engineering and the control condition of horizontal and vertical coordinates in a plant, and implementing a procedure of transporting a responsible operation principal and an operator and a component. And a temporary assembly platform is built in advance, so that the components are prevented from being damaged in the transportation process. According to the special hoisting construction scheme of the granulation tower for the blast furnace project slag treatment project, through advanced planning before component transportation, delivery and matched supply are carried out according to a hoisting requirement program, smooth hoisting on site is ensured, unloading is organized in time after the components reach a construction site, the components can be directly hoisted to a splicing area at a splicing position, secondary carrying is reduced, and the construction efficiency is improved. And under the condition of factory permissible and under the condition of ensuring that hoisting machinery and transport vehicles walk smoothly, the hoisting machinery and the transport vehicles can be sequentially placed near the hoisting position and assembled and then hoisted together with the hoisting machinery and the transport vehicles.

Description

technical field [0001] The invention relates to the technical field of a special construction scheme for hoisting a granulation tower, in particular to a special construction scheme for hoisting a granulation tower for a blast furnace project slag treatment project. Background technique [0002] The blast furnace uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: the furnace throat, the furnace body, the furnace waist, the furnace belly and the hearth. Due to the good technical and economic indicators of the blast furnace ironmaking, The process is simple, the production volume is large, the labor production efficiency is high, and the energy consumption is low. Therefore, the iron produced by this method accounts for the vast majority of the world's total iron production. [0003] The granulation tower is a necessary component in the slag treatment project of the blast ...

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a special construction plan for the hoisting of the granulation tower for the slag treatment project of the blast furnace project, which has the advantages of reasonable planning before operation and overall stable hoisting, and solves the unreasonable operation site and operation specifications during the installation process. It is easy to cause safety hazards during the connection and fixing of the granulation tower or construction. In the current special construction plan for hoisting of the granulation tower, the key hoisting process cannot be accurately operated and controlled.
