A method for repairing the inner wall of a dry-type thin oil-sealed gas cabinet

Abstract

The invention discloses a method for repairing the inner wall of a dry-type thin oil sealed gas tank, which is characterized in that micron blast furnace titanium slag obtained after crushing, microwave pretreatment, grinding, screening and microwave treatment is used as an additive and uniformly added Into the sealing oil in the piston oil groove of the dry-type thin oil sealed gas cabinet, and use the sealing oil flow between the piston oil groove, the oil film on the inner wall of the gas cabinet and the oil groove at the bottom to make the above-mentioned micron-sized blast furnace titanium slag uniform in the oil film on the inner wall of the gas cabinet The gas distribution and flow can complete the repair of the inner wall of the gas cabinet. The invention uses microwave treatment to reduce the grinding difficulty of blast furnace titanium slag and improve the surface energy and surface activity of blast furnace titanium slag, so as to effectively ensure the preparation cost of micron blast furnace titanium slag and the repair effect on the frictional damage of the inner wall of the gas tank. The restoration method is simple and effective, with low cost and obvious technical and economic advantages.

Description

technical field [0001] This patent belongs to the technical field of dry-type thin oil-sealed gas holders in iron and steel plants, and is a repair method for the inner wall of dry-type thin-oil-sealed gas holders. Background technique [0002] Dry-type thin oil sealed gas holders are widely used in iron and steel enterprises in my country. Its main function is to stabilize the pressure of the gas pipe network and avoid gas release. It is of great significance to the safe and stable operation of iron and steel plants, energy saving and emission reduction. The dry-type thin oil sealed gas cabinet ensures the oil level of the sealing lubricating oil (referred to as sealing oil) in the piston oil groove through the sealing device installed on the piston ring beam, so as to realize the sealing of the gas in the cabinet. In the actual operation process, as the piston rises and falls, the rubber sealing block of the sealing device forms a frictional contact movement with the inner...

Problems solved by technology

[0003] At present, studies have shown that the use of nano-TiO 2 , nano-SiO 2 Nano-materials such as lubricating oil additives can repair the friction surface of the material under lubricating oil conditions, and form a corresponding self-repairing film to improve the anti-friction performance of the material, but the above-mentioned nano-materials used as lubricating oil additives are more expensive , high cost of preparation

In addition, there are currently studies using nanoscale blast furnace titanium slag as a lubricating oil additive to repair the surface of magnesium alloy materials. However, due to the compact structure, high hardness and difficulty of grinding of blast furnace titanium slag, the preparation cost of nanoscale blast furnace titanium slag is extremely high. At the same time, the ore phase structure of blast furnace titanium slag is complex, and the surface energy and surface activity are limited.

[0004] To sum up, there is currently no good method for repairing the inner wall of dry-type thin oil-sealed gas holders. How to find an effective and low-cost repair method for the inner wall of gas holders? Safe and stable operation is of great significance
