大连造纸厂有一台国内最大的造纸烘缸,直径为6.23米,宽1.4米。由钢板焊接制成,工作表面喷涂了一层约2毫米厚的不锈钢镀层。该烘缸已经使用6年多,最近发现表面不锈钢镀层局部剥离,剥离部位宽35毫米,长340毫米,深约1毫米。如果全部剥下重新喷涂,需花费3万多元,还要停产一个多月,这样就会影响生产任务和产品质量。为抢修烘缸,市技协组织了焊接和粘接方面的工程技术人员和工人研究,经过各种焊补方法的分析对比,最后决定由大连化学物理研究所专门配制一种耐
Dalian Paper Mill has one of the largest paper-making drying cylinders, measuring 6.23 meters in diameter and 1.4 meters in width. Made of steel, the working surface is coated with a layer of stainless steel approximately 2 mm thick. The dryer has been in use for more than 6 years. Recently it has been found that the surface stainless steel coating is partially peeled off, the peel site is 35 mm wide, 340 mm long and about 1 mm deep. If you peel all the re-spray, it will take more than 30,000 yuan, but also stop production for more than a month, this will affect the production tasks and product quality. In order to repair the drying cylinder, the City Technical Association organized the welding and bonding of engineering and technical personnel and workers, after a variety of welding methods analysis and comparison, the final decision by the Dalian Institute of Chemical Physics, a specially formulated a resistance
