Problems solved by technology

Therefore, it is necessary to weld lifting lugs on the shell assembly ring when hoisting the shell assembly ring, and at the same time, when the shell assembly ring is subjected to tension during hoisting, the ellipticity of the shell assembly ring will change; thus Reduce the installation accuracy and cannot guarantee the ellipticity requirements of the shell

Embodiment

[0108] Install the stainless steel converter using the above installation method for the sulfur acid converter shell

[0109] 1. Production of tooling

[0110] 1.1 Selection of hoisting device and production of expansion ring

[0111] The hoisting device 4 adopts a chain hoist, and the expansion ring 5 adopts channel steel 51 to roll into a circle with the same inner diameter of the shell, and then divides it into three sections equally, and removes a part in the middle to place a screw jack 52 to adjust the expansion. The outer surface of the expansion ring 5 is pasted and welded with a connecting plate 53, and the connecting plate 53 is made of stainless steel to avoid direct contact of carbon steel with the stainless steel shell. Before lifting, the expansion ring 5 is tightened. At the same time, stainless steel ear plates are welded on the upper part of the shell expansion ring 5 to play the role of hanging ears to ensure that the force in the lifting process meets the r...

Abstract

The invention provides a converter shell mounting method capable of reducing overhead operation and improving mounting precision. The converter shell mounting method comprises the following steps: selecting a lifting device and side columns, and mounting a tool; then splicing a shell assembly annular band on a shell foundation, and mounting an expansion ring in the shell assembly annular band after finishing splicing; then, through lifting the expansion ring through the lifting device, lifting the shell assembly annular band to a position that the distance between the lower edge of the shell assembly annular band and the shell foundation meets the requirement of mounting the next circle of shell annular band; then, splicing the next circle of shell assembly annular band, and finishing the connection of the upper and lower two circles of shell assembly annular bands; and then, moving the expansion ring into the next circle of shell assembly annular band, repeating the steps, finishing the mounting of all shell assembly rings except the tail circle, and directly splicing the tail circle of shell assembly ring on the shell foundation. Through adopting the converter shell mounting method, the mounting precision of the shell can be ensured, overhead operation can be reduced, the construction period can be shortened, and the construction cost can be reduced.

Description

technical field [0001] The invention relates to a casing installation method, in particular to a converter casing installation method. Background technique [0002] It is known that the converter is the core equipment of the sulfur acid production plant. With the continuous expansion of the domestic sulfur acid production scale, the stainless steel converter has been widely used. The converter is a metal storage tank with an upright cylindrical structure. The clapboard, central cylinder, grille, etc. are all made of stainless steel, so that the equipment can adapt to higher temperature operation, with long service life and stable production. [0003] The commonly used installation methods of metal storage tanks mainly include the front installation method and the flip method. With the construction of the formal installation method, as the tank body becomes higher and higher, it is difficult to work at heights, and it is difficult to guarantee the quality and safety of the p...
