沈阳铁路局机车弹簧厂是沈阳机务段的附属工厂,承担着东北各局蒸汽机车扁弹簧的制造和修理任务,每年可生产6000多个弹簧,在没改炉前,他们采用的是反射炉,这种炉子火焰直接加热工件,燃料使用效率很低,热量没有得到充分利用,年耗煤量达7百多吨。在加工时工厂上方浓烟滾滾,尘雨纷纷,污染了环境,危害了人民的身体健康,使就近的工厂和住户很不安宁。1972年9月弹簧厂儿名老工人,在工程技术人员的协助下,本着自力更生,艰苦奋斗的精神,苦战15天,成功地建起第一座煤气炉,相继又改造了一座。至此,两座煤气炉
Shenyang Railway Bureau Locomotive Spring Factory is an affiliated factory of Shenyang Locomotive Depot and undertakes the manufacturing and repair tasks of flat springs for steam locomotives of northeast China. Each year, it can produce more than 6000 springs. Before the furnace was changed, they used a reflecting furnace, which The furnace flame directly heating the workpiece, the fuel efficiency is very low, the heat is not fully utilized, the annual coal consumption amounted to more than 700 tons. When processing the smoke billowing above the factory, dust and rain have polluted the environment, endangering the health of the people and leaving the nearby factories and households unharmed. In September 1972, with the help of engineers and technicians, the elder workers of the Spring Factory, having worked hard for 15 days, successfully built the first gas stove and successively transformed one. At this point, two gas stoves
