How to remove the oxide layer inside the small holes after quenching of the rolled tube
How to remove the oxide layer inside the small holes after quenching of the rolled tube.
Can any expert help me? I can remove the oxide layer on the outer surface. The key is that the oxide layer inside the two large and small holes is very difficult to remove!
The purpose of rolling tube quenching is to transform supercooled austenite into martensite or bainite. I don’t need to introduce other transformations. This transformation is the transformation of the entire object, which is not just the surface transformation.
Take out the items and wash them with water to remove surface acid. This oxide film is generally corroded away.
Rolled tubeIt is a steel pipe material that has been processed by cold drawing or hot rolling. Since steel pipes have no oxide layer on the inner and outer walls, can withstand high pressures without leakage, have high precision, high smoothness, no deformation during cold bending, no cracks in flaring and flattening, etc., they are mainly used to produce products with pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes. The chemical composition of the quilted pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
