Abstract

PURPOSE:To obtain a printing cylinder having excellent corrosion resistance by a method in which a stainless steel layer is formed on the surface of the cylinder by padding welding method and the stainless steel layer is left even after the processing of outside diameter. CONSTITUTION:A comparatively thick (6-8mm.) stainles steel layer is formed on the surface of a plate cylinder or blanket cylinder by means of a padding welding method, and a 3-5mm. thick stainless steel layer is left after the outside diameter processing. The pad-welded stainless steel cylinder has very good corrosion resistance because austenite steel surface (of usual SUS 304, etc.) is obtained. Also, damage to small round pants of the corners of the groove can be greatly lessened.

の改善が課題であった。Conventionally, corrosion-resistant surface treatments on the above-mentioned side include plating with chrome, metal, etc., or thermal spraying with stainless steel.
Corrosion occurred due to the acidic liquid used and the deflection and tinting collisions caused by the printing pressure, and pitting occurred in areas with defects in surface treatment such as plating. Furthermore, in the rounded corners of the grooves in the folding part of clothing, the plating can often be damaged due to impact when the plate is pushed into the groove using a metal spatula during the plate folding process, so improvement of corrosion-resistant surface treatment methods is necessary. was the issue.

This leaves a layer of stainless steel.

Since it has an extremely thick layer of stainless steel, it can significantly improve its corrosion resistance.In 90 stainless steel flesh welding, a hoop with a width of 50 to 75 cm, called band arc welding, can be made by submerged arc welding. By overlaying in ~3 layers, it is possible to overlay to a thickness of 6 to 8 mm. Overlaying is not limited to band arc welding, and may be submerged arc welding using wire or welding using inert gas such as MIGSTIG. Band arc welding is preferable because it is highly productive when manufacturing shells in large quantities. With overlay welding of 1g4, you can obtain the surface of austenitic steel such as normal 5US304, so it has excellent corrosion resistance, and even when damaged at the small rounded corner of the ξ section, it is better than stainless steel. It was possible to obtain a remarkable effect without having to reduce the toughness.
