4、n:0.13%(10minutesat1000C)二.鑄寶砂鑄造陶粒具有如下優(yōu)點1 1 . .球狀粒形粒形接近真圓，表面光滑，無凹凸脈紋。其流動性及填充性好，能得到良好的成型性和鑄模強度。潰散性好，易于清砂作業(yè)。粘結(jié)劑使用量較其他同類型砂有較大的節(jié)省。2 2 . .熱膨脹率低熱膨脹率之低于銘礦砂等特殊砂相近，所以，生產(chǎn)鑄件的尺寸精度高，破裂及表面缺陷少，鑄件成品率高。3 3 . .耐破碎性好鑄寶砂的致密性好，強度高，即使重復(fù)再生使用也很少破碎，減少鑄造生產(chǎn)過程中的粉塵對生產(chǎn)環(huán)境的污染，再生性好，減少產(chǎn)業(yè)廢物排放，利于環(huán)境保護。4 4 . .耐火性好主要成分是氧化鋁，所以耐火性能很好。耐火度 A
