Problems solved by technology

However, the operation of the hoist depends entirely on the vision of the operator and the cooperation between the personnel. It is easy to cause coordination errors due to untimely information transmission, resulting in bumps on the tuyere cover. In addition, there are many unsafe factors in the cooperation between man and machine.

Embodiment Construction

[0021] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] see figure 1 , figure 2 and image 3 , a kind of tuyere cover installation construction method comprises the following steps:

[0023] Step (1), respectively mark the cross center line on the tuyere sleeve 12 and the tuyere 13 of the ironmaking blast furnace;

[0024] Step (2), put the tuyere cover 12 in the step (1) on the lever for installation and construction of the tuyere cover, lift it to the vicinity of the center line of the tuyere 13 of the ironmaking blast furnace, and then adjust the center line of the tuyere cover 12 to be in line with the smelting furnace. The centerlines of the tuyeres 13 of the iron blast furnace coincide;

[0025] Step (3), push the tuyere cover 12 forward to the installation position with the lever for the installation and construction of the tuyere cover in step (2), and always ensure that the concentricity ...

Abstract

The invention relates to a construction method for a tuyere, which comprises the following steps of: (1) respectively marking cross center lines at a nozzle of the tuyere and a nozzle of a blast furnace for making iron; (2) penetrating the tuyere in the step (1) on a lever for constructing the tuyere and hoisting the level to the center line of the tuyere so as to be superposed with the center line of the blast furnace for making iron; and (3) pushing the tuyere forwards to a mounting position by using the lever for constructing the tuyere in the step (2), finishing mounting and retracting the lever for constructing the tuyere. The invention has the benefits that: firstly, the construction method is safe and reliable, the equipment damage possibly generated in the mounting process is avoided and construction risks are reduced; secondly, the construction method is simple, the labor force and physical materials can be effectively saved, the construction period is shortened and the work efficiency is increased; and thirdly, matching links between people and a machine are reduced and the misoperation can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of tuyere sleeves for ironmaking blast furnaces, in particular to a method for installing tuyere sleeves. Background technique [0002] The blast furnace used for ironmaking in the metallurgical industry has many tuyeres that blow air into the furnace, and each tuyere is equipped with a tuyere cover. Therefore, the tuyere cover is an important part of the ironmaking blast furnace, and its quality directly affects the ironmaking production. The main technical and economic indicators. At present, the installation of the tuyere cover generally adopts the method of chain-down and winch hoisting. When installing the tuyere cover, fix one end of the tuyere cover with a steel wire rope on the winch and pull it toward the tuyere of the blast furnace, and fix the other end with an inverted chain and pull it backward to offset the impact of the winch. However, the operation of the hoist depends entirely on the visio...
