  T型槽平臺注意(yi)事(shi)項

  T型槽平(ping)(ping)臺的(de)(de)生產(chan)過(guo)程中會(hui)出現一(yi)些產(chan)品缺(que)(que)陷(xian)(xian),只要(yao)采用正確的(de)(de)方法可以進行工(gong)藝彌補,鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)工(gong)作面的(de)(de)缺(que)(que)陷(xian)(xian)是不可以忽(hu)視的(de)(de)重要(yao)部位,鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)主要(yao)的(de)(de)缺(que)(que)陷(xian)(xian)包括:氣孔、沙(sha)孔、夾沙(sha)、縮松等(deng)。鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)的(de)(de)缺(que)(que)陷(xian)(xian)在《中華人民(min)共和(he)國機(ji)械行業標準》jb/t 7974—2000里有(you)處理(li)(li)的(de)(de)詳細規定。鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)使用壽(shou)命(ming)和(he)缺(que)(que)陷(xian)(xian)修復有(you)密切的(de)(de)關系。所以對鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)的(de)(de)缺(que)(que)陷(xian)(xian)做修復時要(yao)嚴格按工(gong)藝要(yao)求(qiu)處理(li)(li)。
