广州南洋电器厂高级工程师余瑚琏积二十年之久,首次取得硅钢片极面长期防锈成功的科研成果,填补了国内外硅钢片铁芯长期防锈的空白,是一项具有世界先进水平的科研成果.应用此项工艺将可以省掉现今硅钢片铁芯防锈的电镀、喷漆、涂油等各种工序和经常性的防锈维修,并可延长使用寿命,给社会带来巨大的经济效益.此项科研成果在1988年联合国知识产权组织在我国主办的北京国际发明展览会上获得金牌奖,并被编入《中国技术成果大全》.
Yu Hong, a senior engineer of Guangzhou Nanyang Electrical Appliance Factory, has been striving for a long-term rust-prevention scientific research achievement of silicon steel sheet for the first time for over 20 years. It has filled the gap of long-term rust prevention of silicon steel cores at home and abroad and is a world advanced level. Scientific research results. Application of this technology will eliminate current rust-proof plating, painting and oil coating of silicon steel sheet cores and regular rust-proof maintenance, prolong service life, and bring huge economic benefits to society. Benefits. This scientific research achievement won the gold medal award at the Beijing International Invention Exhibition held by the United Nations Intellectual Property Organization in China in 1988 and was incorporated into the “Encyclopedia of China’s Technical Achievements”.
