Abstract

The invention relates to a replacement method of a coke oven column upper part cross-brace. The replacement method is characterized by comprising the following steps that a, two clamping tools with the same structure are manufactured; b, ear plates are welded to the middles of inner side box irons of the corresponding well-shaped clamping tools; c, a steel wire rope tensioner is provided for beinghung on one of the ear plate, and a steel wire rope is provided; and d, the steel wire rope tensioner is used for tensioning the steel wire rope, and replacement of the oven column upper part cross-brace is conducted after oven columns on the machine side and the coke side are tensioned. The replacement method of the coke oven column upper part cross-brace has the advantages that the clamping tools are simple in structure, manufacturing is convenient, the engineering quality is safe and reliable, the clamping tools are adopted to avoid damage of the over column, the operation efficiency is greatly improved, the clamping tools can be repeatedly used, and the engineering cost is lowered.

Description

technical field [0001] The invention relates to the replacement of a damaged coke oven protective device, in particular to a method for replacing the upper horizontal brace of the coke oven column. Background technique [0002] The coke oven is an indispensable production facility in the modern industrial field. The furnace protection equipment is one of the key equipment. The equipment on both sides of the machine and the coke are connected and tightened by the upper and lower bars of the furnace column. Due to the influence of high temperature, complex force and other factors on the upper part of the furnace column during the production process, the tie rods will be damaged and need to be replaced. [0003] Since the top of the coke oven in the production state belongs to a high-temperature working environment, the traditional method to replace the upper braces of the furnace column is to weld the force on the furnace column with lug plates or steel wire ropes to directly ...
