前言钢铁工业在现阶段正站在祖国经济建设的首要地位,随着钢铁工业的发展,钢铁的分析工作,更其重要了。因为分析工作关系到合金在制造过程中的控制及其应用,尤其目前我们不但要增加产品的数量,还要加强质量,因而每根钢材、每炉铁水或铸件,均须化验,所以化验工作是更多而且繁重了。如果分析工作者仍按过去化验的方法,是绝对跟不上目前配合生产的要求的。因为过去的方法,费时很多,操作复杂,同时亦只能在实验室中或具备一定的条件下,才能进行,已不适於目前各工厂现场或炉前试验的要求。 Foreword The steel industry is at the forefront of economic development in the motherland at this stage. With the development of the steel industry, the analysis of steel is even more important. Because the analysis is related to the alloy’s control and its application in the manufacturing process, especially at present we not only need to increase the quantity of products, but also enhance the quality so that every steel, each hot metal or casting must be tested. Therefore, More and more heavy. If analysts still follow the methods of past tests, they will absolutely not keep up with the current requirements of supporting production. Because the methods in the past are time-consuming and complicated to operate, they can only be carried out in laboratories or under certain conditions and are not suitable for the current requirements of the factory or on-site tests.
