钢的宏观缺陷检查也叫低倍缺陷检查,通常是借用肉眼或低倍放大镜来观察和判断缺陷的性质。酸洗硫印只不过是其中的一种检验方法,它是直接对零件进行试验,其特点是设备简单,操作方便,能够在大面积上清晰地显示钢铁材料的各种缺陷,为判断钢的质量提供了重要依据。一、酸洗硫印用于重要零部件的质量检查机械制造业所生产的动力机械、化工机械和船舶机械中的大型锻件与重要零部件,在生产过程中以及接近完工状态有许多部位要进行酸洗硫印检
Macro inspection of steel, also known as low defect inspection, is usually borrowed from the naked eye or low magnification to observe and judge the nature of defects. Pickling sulfur seal is only one of the test methods, it is directly on the part of the test, which is characterized by simple equipment, easy operation, large areas can clearly show the various defects of steel materials, to determine the steel Quality provides an important basis. First, the pickling sulfur seal used for the quality inspection of important components Machinery manufacturing industry production of power machinery, chemical machinery and ship machinery in large forgings and important parts in the production process and near completion of the state there are many parts to be carried out Pickling sulfur detection
