破(po)碎(sui)機(ji)在生(sheng)產和檢修過(guo)程中經(jing)常(chang)(chang)出現破(po)碎(sui)壁與軋臼壁松動、固(gu)定困難等問(wen)題(ti)，嚴(yan)重影響(xiang)生(sheng)產正(zheng)常(chang)(chang)運行。根據以往經(jing)驗可(ke)知，更換一(yi)個(ge)破(po)碎(sui)機(ji)襯(chen)板(ban)(ban)及澆注(zhu)所需(xu)時間大(da)約為7～10天，更換周期(qi)過(guo)長(chang)，嚴(yan)重影響(xiang)正(zheng)常(chang)(chang)生(sheng)產進度(du)，由此看出,提(ti)高襯(chen)板(ban)(ban)的耐磨性能(neng),延長(chang)襯(chen)板(ban)(ban)的使(shi)用壽命也(ye)是一(yi)個(ge)很(hen)重要的問(wen)題(ti)。
高(gao)(gao)錳鋼(gang)是在(zai)破碎機(ji)和(he)磨礦機(ji)中應(ying)用(yong)非(fei)常廣泛的一種(zhong)耐(nai)(nai)磨材(cai)料(liao)(liao),因(yin)為它具有(you)很(hen)高(gao)(gao)的韌(ren)性和(he)良好的加工硬化(hua)特(te)性。而銘信(xin)生(sheng)(sheng)產(chan)的超強韌(ren)高(gao)(gao)抗磨中鉻合金(jin)材(cai)料(liao)(liao)耐(nai)(nai)磨襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)，是通過切割、卷板(ban)(ban)(ban)(ban)變(bian)形、打孔(kong)和(he)焊接耐(nai)(nai)磨鋼(gang)板(ban)(ban)(ban)(ban)等生(sheng)(sheng)產(chan)工藝(yi)加工而成(cheng)各種(zhong)耐(nai)(nai)磨襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)，如輸送(song)機(ji)襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)、給煤機(ji)底板(ban)(ban)(ban)(ban)/旋風分離(li)器倒(dao)錐和(he)襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)、耐(nai)(nai)磨葉(xie)片等，與眾多耐(nai)(nai)磨材(cai)料(liao)(liao)相比(bi)(bi)，耐(nai)(nai)磨復合鋼(gang)板(ban)(ban)(ban)(ban)有(you)其不可(ke)(ke)替代的顯(xian)著特(te)點(dian)，耐(nai)(nai)磨壽命(ming)可(ke)(ke)比(bi)(bi)普通鋼(gang)板(ban)(ban)(ban)(ban)提高(gao)(gao)15倍(bei)以(yi)上。鄭州銘信(xin)生(sheng)(sheng)產(chan)的各類磨機(ji)襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)采用(yong)超強韌(ren)高(gao)(gao)抗磨中鉻合金(jin)材(cai)料(liao)(liao)精工制造的Φ5×10.5m大(da)型生(sheng)(sheng)料(liao)(liao)磨機(ji)襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)，預期壽命(ming)比(bi)(bi)高(gao)(gao)錳鋼(gang)提高(gao)(gao)2-3倍(bei)。同時(shi)，各類磨機(ji)襯(chen)(chen)(chen)(chen)板(ban)(ban)(ban)(ban)可(ke)(ke)以(yi)根(gen)據(ju)用(yong)戶需求“量體裁衣”定向(xiang)設計(ji)。
