钢铁企业中的动力机械设备,在运转中常引起大量噪音,尤其是制氧车间的空气、氧气等的压缩机械,高炉的鼓风机、放风装置,以及其它中小型鼓风机产生的噪音,更为突出。近些年来,噪音已被列为国际公害之一,如何与噪音作斗争已成为环境保护的一项重要课题。 Power machinery and equipment in the iron and steel enterprises often cause a lot of noise during operation. In particular, noise from air and oxygen compressors in the oxygen plant, blast furnace blowers and blowers, and other small and medium sized blowers are more prominent. In recent years, noise has been listed as one of the international public hazards. How to fight noise has become an important issue for environmental protection.
