江西省钨精矿的生产占有很重要的地位,全省拥有大、中型钨矿十余座。钨矿石大多为花岗岩,硬度高,普氏硬度f=12～16,选矿厂使用的砂泵易损件寿命很短,耗量大。浒坑钨矿系中等规模,选矿厂采用2时立式砂泵40台,长期以来砂泵的易损件都是由矿机修厂用普通白口铸铁制作,使用寿命仅5～7天。由于更换泵件频繁,劳动强度高,停工时间多。为此,我们对高铬白口铸铁以稀土元素进行变质
Production of tungsten concentrates in Jiangxi Province occupies a very important position, the province has more than ten large and medium-sized tungsten ore. Tungsten ore is mostly granite, high hardness, Platts hardness f = 12 ~ 16, beneficiation plant sand pump wearing parts life is very short, consumption. Hu Hang tungsten mine medium-scale, dressing plant with 2 vertical sand pump 40, a long time the wearing parts of the sand pump are made by the mining plant with ordinary white cast iron, the service life of only 5 to 7 days. Due to frequent replacement of pump parts, high labor intensity, downtime and more. For this reason, we treat the high-chromium white cast iron with rare earth elements
