抚顺钢厂检验室自一九五三年四月执行部颁标准后,由于检验项目增多,检验质量要求更加严格;加之,当时该室领导对执行部颁标准后可能遇到的困难估计不足加以工作调配不好,因而造成检验钢样的积压,严惩地影响生产任务的完成,同时造成用户停工待料。从中华全国总工会提出开展技术革新运动之后该室职工针对上述问题,展开了技术革新工作,出现了像刘桂芬快速定矽法这样的先进人物和先进事迹,大大地提高了生产效率,消除了检验钢样的严重积压现象。甲、取得的成绩: 一、改进了操作,解决了生产上的关键问题: 1.中空钻试验成功。过去取一支抗张试样,必须经过锯床及车宋两道工序,试样供应不及时;使用中空钻后效率可提高四倍,消减了检验钢样的积压现象,同时给国家节省财富四亿七千万元。 2.用铣刀铣裂冲击口。原冲击口加工是先用铇床铇,然后用砂布磨,因工具及操作不当,废品率多在50％以上;加工班班长苏双奎研究制造铣冲 Fushun Steel Laboratory since April 1953 after the implementation of ministerial standards, due to increased inspection items, inspection quality requirements more stringent; In addition, at that time the leadership of the room after the implementation of ministerial standards may encounter difficulties underestimated to be Poor allocation of work, resulting in the inspection of steel backlog, severely punished to affect the completion of production tasks, while causing the user to stop work to be expected. After the All-China Federation of Trade Unions proposed to carry out the technical innovation movement, the staff of this office started the technical innovation work in response to the above-mentioned problems. The advanced figures and advanced deeds such as Liu Guifen’s rapid determination of silicon law have emerged, greatly improving the production efficiency and eliminating the inspection Serious backlog of steel samples. A, the achievements made: First, to improve the operation to solve the production of the key issues: 1. Hollow drill test success. In the past to take a tensile specimen, must go through the sawing process and car Song two procedures, the sample supply is not timely; the use of hollow drill efficiency can be increased fourfold, reducing the backlog of test steel samples, while saving the country four Seven hundred million yuan. 2. Milling the impact mouth with a milling cutter. The original impact port processing is to use 铇 bed 铇, and then use emery cloth, due to improper tools and operations, the rejection rate more than 50%; processing class monitor Su Shuangkui research and manufacture of milling
