我矿使用的MQG1500×3000球磨机,原用本矿和外单位加工的铸铁勺头,使用期限为7～15天。由于勺头易磨损,更换次数频繁,影响了生产。我们采用一些废旧钎头的合金片及钢板,加工成球磨机勺头。具体做法是:用16毫米与12毫米的钢板电焊接成勺头体。氧气压力调至2～4(公斤/厘米~2)获得蓝白色火焰焊接合金片。把火焰与合金片短暂接触,使合金片之间局部熔合,并焰熔4
The MQG1500 × 3000 ball mill used by mine is originally made of cast iron spoon machined by this mine and the other units with a service life of 7-15 days. As the spoon is easy to wear, frequent replacement, affecting the production. We use some of the old bits of alloy steel and scrap, processed into a ball mill spoon. The specific approach is: 16 mm and 12 mm steel welded into the head body. Oxygen pressure adjusted to 2 ~ 4 (kg / cm ~ 2) to obtain blue and white flame welding alloy film. Briefly contact the flame with the alloy flakes to locally fuse the alloy flakes and flame 4
