目前,国产还原铁粉主要有两种,一种为粉末冶金用铁粉,一种为焊条用铁粉。国内铁粉生产厂家,细粉碎所采用的设备大多为振动式球磨机或高速粉碎机。由于采用的机型不同,其单机效率、能耗、维护费用和所生产铁粉的性能都有差异,我们从“天津粉末冶金厂”“天津粉末冶金厂南董分厂”“天津勃海粉末冶金厂”“山西平定粉末冶金厂”和“石家庄光华粉末冶金厂”等的细碎设备的安装调试中体会到:生产粉末冶金制品用并兼顾其它用途的铁粉,从工艺来讲要容易些;反之,如果生产焊条用并兼顾粉末冶金制品用铁粉,从性能上满
At present, there are mainly two kinds of domestic reduced iron powder, one is iron powder for powder metallurgy and one is iron powder for welding rod. Domestic iron manufacturers, most of the equipment used in the fine grinding vibrating ball mill or high-speed mill. Due to different models, its stand-alone efficiency, energy consumption, maintenance costs and the performance of iron powder produced are different, we from the “Tianjin Powder Metallurgy Plant”, “Tianjin Dongfen Powder Plant Plant”, “Tianjin Bohai Powder Metallurgy Plant ”“ Shanxi Pingding Powder Metallurgy Plant ”and“ Shijiazhuang Guanghua Powder Metallurgy Plant ”and other fine equipment installation and commissioning experience: the production of powder metallurgy products and take into account other uses of iron powder, from the process is easier; and vice versa , If the production of electrodes with both powder metallurgy products, from the performance is full
