常州无线电元件六厂磁芯制造部是厂内耗电大户，用电量占全厂的８０％以上。在磁芯生产中需要进行两次烧结。一次是制料过程中将充分混合的粉料制成Φ２～６ｍｍ的小球，然后在回转窑中进行焙烧，我们称之为“预烧”。另一次是将加工成一定形状和尺寸的半成品进行烧结，完成各 Changzhou radio components factory six magnetic core manufacturing plant is a large power plant, electricity consumption accounts for more than 80% of the plant. In the core production requires two sintering. Once the mixing process will be fully mixed powder made of Φ2 ~ 6mm pellets, and then roasted in a rotary kiln, which we call “pre-burn.” The other is to be processed into a certain shape and size of the semi-finished products for sintering
