Method for preventing cutting slag during drilling holes in inner wall of stainless steel airtight container

Abstract

The invention relates to a method for preventing cutting slag during drilling holes in the inner wall of a stainless steel airtight container. The technical scheme for solving the technical problems is as follows: before the seal heads at the two ends of the container are welded, protective rubber plates are used; the length of the each rubber plate is equal to the length of the container, and the width of each rubber plate ensures that the rubber plate covers the half of the inner wall of the container; the rubber plates are paved on the inner wall of the container, and then holes of which the positions and sizes can be determined at the early stage are drilled at first; for the holes drilled after the seal heads are welded, 2mm-thickness rubber plates resistant to high temperature can be used, the length of each rubber plate is a half of the length of the container, and the width of each rubber plate is more one third of the circumference of the container; the rubber plates are folded and are stuffed into the container from the pre-drilled positions, and are automatically or manually spread; the rubber plates are tiled, then the holes are drilled, and most of the generated cutting slag can fall on the stuffed rubber plates. The method has the beneficial effects that the method can effectively prevent the cutting slag from falling on and attaching to the inner wall of the container, and therefore the welding and processing at the later stage cannot be affected.

Description

technical field [0001] The invention relates to a method for preventing cutting slag on the inner wall of a stainless steel airtight container, specifically a method for opening a stainless steel airtight container without protection, a large amount of cutting slag will adhere to the inside of the container, and because the stainless steel material The reason is that the attached cutting slag is firm and difficult to remove or cannot be removed at all because the opening is too small, so it is a protective measure taken before or during opening. Background technique [0002] When the stainless steel airtight container is opened, the slag generated on the inner wall is not easy to remove. If the treatment is not clean, it will seriously affect the quality of welding, processing and anti-corrosion in the later stage. The existing slag will also cause corrosion on the inner wall. Waiting for tools to be polished is time-consuming, laborious, and unsafe, and may not be polished ...

[0002] When the stainless steel airtight container is opened, the slag generated on the inner wall is not easy to remove. If the treatment is not clean, it will seriously affect the quality of welding, processing and anti-corrosion in the later stage. The existing slag will also cause corrosion on the inner wall. Waiting for tools to be polished is time-consuming, labor-intensive, and unsafe, and may not be polished due to the small opening of the sealed container and the limited internal space
