为完成今年1070万吨钢的生产任务,在新建成的转炉炼钢车间相互介绍和交流如何使用鼓风机的经验是有重大意义的。以下我们将使用情况加以整理,提出几点意见供兄弟厂参考。新设计的大容积转炉所配备的鼓风机,都采用高压串联离心式鼓风机。这种7-17-1#9~1/2型的鼓风机(沈阳扇风机厂出品)的额定静压和风量是3300公厘水柱(即240公厘水银柱)和84立方公尺/每分。其特性与一般罗茨式风机不同:当转数(2970)不变时,压力减小,风量增大而所需功率亦增大;反之压力
In order to accomplish the production of 10.7 million tons of steel this year, it is of great significance to introduce and exchange experience on how to use the blower in the newly built converter steelmaking plant. The following we will use the situation to be put together to make comments for the brothers plant for reference. The newly designed blower with a large volume converter is equipped with a high-pressure series centrifugal blower. The rated static pressure and volume of the 7-17-1 # 9-1 / 2 blowers (manufactured by Shenyang Fan Factory) are 3300 mmHg (240 mmHg) and 84 m 3 / . Its characteristics and the general Roots blower is different: When the number of revolutions (2970) unchanged, the pressure decreases, the air volume increases and the required power also increases; the other hand, the pressure
