刮(gua)板(ban)(ban)(ban)(ban)機(ji)中(zhong)(zhong)部(bu)槽(cao)(cao)是刮(gua)板(ban)(ban)(ban)(ban)輸送機(ji)的機(ji)身，由中(zhong)(zhong)板(ban)(ban)(ban)(ban)和槽(cao)(cao)幫剛等組成，上槽(cao)(cao)運煤下槽(cao)(cao)供刮(gua)板(ban)(ban)(ban)(ban)鏈返程(cheng)用(yong)。傳統刮(gua)板(ban)(ban)(ban)(ban)機(ji)中(zhong)(zhong)部(bu)槽(cao)(cao)的中(zhong)(zhong)板(ban)(ban)(ban)(ban)對接后表(biao)面的平(ping)面度有(you)較大(da)誤差(cha)，增大(da)了(le)(le)刮(gua)板(ban)(ban)(ban)(ban)運行阻力(li)，加速了(le)(le)中(zhong)(zhong)板(ban)(ban)(ban)(ban)的非正常(chang)磨(mo)損。我(wo)單位生產的刮(gua)板(ban)(ban)(ban)(ban)輸送機(ji)耐磨(mo)中(zhong)(zhong)部(bu)槽(cao)(cao)和普通型的相比，其(qi)使用(yong)壽命平(ping)均延長了(le)(le)2-3倍(bei)，大(da)幅度減少(shao)了(le)(le)返修工作(zuo)量，顯著提高了(le)(le)煤礦經濟效(xiao)益。
刮(gua)(gua)(gua)板(ban)機中(zhong)部(bu)槽(cao)是刮(gua)(gua)(gua)板(ban)輸送(song)機的(de)(de)(de)機身，由中(zhong)板(ban)和槽(cao)幫剛等組成，上槽(cao)運煤下槽(cao)供刮(gua)(gua)(gua)板(ban)鏈返程用(yong)。傳統(tong)刮(gua)(gua)(gua)板(ban)機中(zhong)部(bu)槽(cao)的(de)(de)(de)中(zhong)板(ban)對(dui)接后表面的(de)(de)(de)平面度有較大誤(wu)差，增大了刮(gua)(gua)(gua)板(ban)運行阻力，加速了中(zhong)板(ban)的(de)(de)(de)非(fei)正(zheng)常磨(mo)損。我單位(wei)生產的(de)(de)(de)刮(gua)(gua)(gua)板(ban)輸送(song)機耐磨(mo)中(zhong)部(bu)槽(cao)和普通型的(de)(de)(de)相比，其使用(yong)壽(shou)命平均(jun)延長(chang)了2-3倍，大幅度減少了返修(xiu)工(gong)作量，顯著提高了煤(mei)礦經濟效益。
1. 抗沖擊(ji)力高于中(zhong)板(ban) 16Mn 鋼板(ban)，不開裂，不剝落。
2. 平均硬度(du)為 HRC60-70 ，為中板(ban)的三倍(bei)以上。
3. 摩擦系(xi)數比(bi)中板降低(di) 50% 。
4. 耐酸耐堿(jian)耐鹽水(shui)腐蝕性是(shi) 16Mn 鋼板的10 倍(bei)以上。
5. 按照刮板運(yun)行方式經計算(suan)合理布局，使運(yun)行阻(zu)力(li)和噪音降至很低。
