我国机械工业的调整和发展,对机械产品的品种、质量要求越来越高,这不仅是各行各业经济增长的需要,也是我国机械产品能否尽快打入国际市场和跨入技术先进行列的关键。为此,在整顿企业与提高经济效益中,首先要做好技术基础工作。所以编制具有国际先进水平又符合我国实际生产需要的标准具有重要意义,也是我们热处理工作者极为迫切的任务。国外,如日本、联邦德国等工业技术发达的国家,已建立了较完整的热处理技术标准体系。联邦德国国家标准(DIN)中有热处理技术标准专栏,搜集到的热处理技术标准有24个,其中热处理检测方法标准4项、名词术语标准5项、钢材质量检测标准3项、热处理工艺标准6项、热处理标准5项、用淬透性选择钢材标准1项。
The adjustment and development of the machinery industry in our country requires more and more varieties and qualities of mechanical products. This is not only the need of economic growth of all trades and industries, but also whether our machinery products can enter the international market as soon as possible and enter the advanced technology ranks The essential. To this end, rectifying enterprises and improving economic efficiency, we must first do a good job in basic technical work. Therefore, the preparation of the international advanced level and in line with China’s actual production needs of the standard is of great significance, but also our extremely urgent task of heat treatment workers. Abroad, such as Japan, the Federal Republic of Germany and other industrialized countries have established a more complete system of heat treatment technology standards. Federal German National Standard (DIN) in the heat treatment technology standard column, collected heat treatment technology standards are 24, of which four heat treatment test standards, five terms terminology standards, steel quality testing standards 3, 6 heat treatment process standards , Heat treatment standards 5, with a hardenability selection of steel standard 1.
