在火力发电厂的钢炉安装中,水冷壁、过热器和再热器等受热面管子需逐根进行通球试验。为此,安装一台锅煤炉时,需要大量不同规格的木质圆球。过去,我们采用样板刀靠或用圆弧刀双手控制进行车削加工,这两种方法,在木球加工过程中都需停车测量,不但加工时间长、效率低,而且工人劳动强度大,表面粗糙度高,加工精度低,甚至有时还加工成椭圆形或桃
In the thermal power plant steel furnace installation, the water wall, superheater and reheater and other heating surface pipe by-pass ball test. To this end, the installation of a boiler stove, you need a large number of different specifications of the wooden ball. In the past, we used the prototype knife or arc knife with both hands to control the turning process. Both of these methods require parking measurement during the processing of the pellets. They not only have long processing time and low efficiency, but also have labor-intensive and rough surfaces High degree of processing accuracy is low, and sometimes even processed into oval or peach
