设备是工业生产的重要物质基础。随着工业生产的发展,机械化和自动化程度不断提高,设备维修工作在企业生产活动中占的比重也越来越大。西德冶金企业中,维修人员占职工总数的25％,我国冶金企业中的维修人员约占30％。西德一座现代化高炉取代三座老式高炉之后,生产工人减少了70％,而维修工人只减少了20％;六十年代末期有四座转炉的炼钢厂,按每月生产一千吨钢换算,需要4.2人,而七十年代中期具有相同生产能力的两座转炉的炼钢
Equipment is an important material basis for industrial production. With the development of industrial production, the degree of mechanization and automation has been continuously improved, and the proportion of equipment maintenance work in the production activities of enterprises is also increasing. In West Germany’s metallurgical enterprises, maintenance personnel account for 25% of the total number of employees, and maintenance personnel in metallurgical enterprises in China account for approximately 30%. After a West German modern blast furnace replaced three old blast furnaces, the number of production workers was reduced by 70%, while maintenance workers only decreased by 20%; in the late 1960s, there were four converter steel mills, which were converted to a monthly production of one thousand tons of steel. Requires 4.2 people, and steelmaking of two converters with the same production capacity in the mid 1970s
