在毛主席无产阶级革命路线指引下,波澜壮阔的批林批孔运动正在全国范围内开展。它有力地推动着我国社会主义革命和社会主义建设事业向前发展。电力工业是国民经济的先行官。随着我国电力生产的飞跃发展,大容量高参数机组的逐渐增多,电厂金属工作也就越来越具有重要意义。近年来,电力部门又增添了不少新的金属测试人员。为了更好地配合电厂金属监督工作和金属测试技术工作的开展,我们本着对电厂金属知识普及与提高的目的,着手编写了“电厂常用金属材料金相图集”,用图片形式进行金属基础知识的普及,文字说明力求通俗,以供从事上述工作的同志参考。“图集”分三个部分。第一部分偏重于电厂常用金属材料的几种基本组织形态和部分热处理后组织;第二部分图列了焊接接头的金相组织及其缺陷;第三部分列举了金属部件在长期运行后的组织变迁及部分损坏事故图例。计有宏观、微观图片约500余帧。在汇编过程中,曾得到许多兄弟单位的支持与具体帮助,在此,谨致衷心的谢意。由于我们水平不高,局限性较大,“图集”还存在不少缺点和错误,请同志们批评指正。
Guided by Chairman Mao’s proletarian revolutionary line, the magnificent Linchi-dong movement is being carried out nationwide. It has vigorously promoted the development of our socialist revolution and socialist construction. Power industry is the forerunner of the national economy. With the rapid development of power generation in our country, the large-capacity and high-parameter generating units are gradually increasing, and the metal work in power plants is becoming more and more important. In recent years, the power sector has added many new metal testers. In order to better meet the supervision of power plant metal and metal testing technology work carried out in line with the purpose of popularization and improvement of metal knowledge of power plants, the preparation of the power plant metallurgical commonly used metal material set, with the picture as a metal base The popularization of knowledge, the textual instruction sought to be popular for reference by comrades engaged in the above work. “Atlas” is divided into three parts. The first part focuses on several basic organizational forms and parts after heat treatment of common metal materials used in the power plant. The second part shows the microstructure and defects of welded joints. The third part lists the organizational changes of metal parts after long-term operation And some examples of damage to the accident. There are macroscopic, microscopic pictures about 500 frames. In the process of compilation, we have received the support and concrete help of many brothers and units. Here, we sincerely thank you very much. Due to our low level and great limitations, there are still many shortcomings and mistakes in the Atlas, so please comrades criticize and correct them.
