1. Ugqoke umshini wepuleti le-coarse bing liner liner kanye nokukhethwa kwezinto ezingamelana nokugqokwa
Izinga elishaqisayo lokugaya ama-coarse lingu-15mm-25mm, ububanzi obumaphakathi we-spirical wokugaya ngungu-75mm, kanye nobubanzi obukhulu obukhulu obuyindilinga Φ 90mm-L Oomm. Lapho i-mill iphenduka, ibhola kanye nokuqukethwe kusike ipuleti lokulahla ngamandla amakhulu amathonya; I-Ball Squeethe impahla ekuhambeni ngokugeleza noma ukugoqa, ngakho-ke indlela yokugqoka ye-raugh liner liner isekelwe ekugqokeni okuphezulu kokuncipha kokugqokwa kokuncipha, okunenzuzo ngokusika kokukhishwa.
Izinto ezihlanzekile zokugaya izimfuno zokugaya izidingo zokulinganisa izidingo zinobunzima obanele, ukusika izidingo zezinto ezibonakalayo ngobulukhuni obuphezulu. Ngokusho komgomo wokugqoka, ubulukhuni bezinto ezibonakalayo (HM) buzoba ngaphezu kwezikhathi eziyi-0,8 zobulukhuni bezinto ezibonakalayo (ha), okungukuthi HM / HA 0.8, kanye nobulukhuni be-Clement Clinker yi-HRC 49-54. Ngakho-ke, ubunzima be-lining plate impahla kufanele ibe ngaphezulu kwe-HRC 50 Ngakho-ke, ipuleti le-coarse lin linning ipuleti kufanele likhethwe i-medium carbon chromium allomium alloy kanye nezinto ezifanayo zensimbi, Hardness HRC 48-55, I-Impact Glueness AKL 5-20J / CM2, Impilo Yesevisi kuze kube yiminyaka emi-2-3. Okomuntu oyedwa we-Screw Hole Liner ne-Groove Liner, khetha i-chromium ephezulu ye-chromium cast ngensimbi efanelekile, futhi impilo yenkonzo ingafinyelela iminyaka engu-4-6. Kuma-lill amamitha amakhulu ngaphezulu Φ 300 Kufanele akhethe ubunzima obuphezulu we-chromium cast iron, Hardness HRC 58-62, Umthelela Fauthness Ak8-12J / CM2, Impilo Yenkonzo kuze kube yiminyaka engu-6-10.

Le ndaba engena embhalweni omuhle wokugaya ngebhodi yokwahlukanisa selibe mncane, futhi i-angle ebukhali isiphenduke i-blunt. Ububanzi bebhola noma ingxenye emgqonyeni omuhle wokugaya yile Φ 15Mm-60mm, futhi amandla okuthobeka mancane, ngakho-ke amandla ethonya anciphile, ngakho-ke inqubo yokugqoka ye-liner yokugaya kancane ukugqokwa kwebhola.
Fine grinding bin lining plate can choose high hardness, low toughness of wear-resistant materials. Such as high carbon alloy steel, high, medium and low chromium cast iron, anti-wear ductile cast iron and other materials, hardness HRC>I-50, umthelela ulukhuni ak4-6J / cm2 angasetshenziswa.
I-Mill lining Plate akufanele ikhethe insimbi ephezulu ye-manganese. Ukuze uthole indawo yokugcina impahla egaya, ngoba amandla wesivuno ensimbi ephezulu ye-manganese iphansi, kulula ukukhiqiza i-deformation yepulasitiki, usayizi omude wepuleti lokulayini uzokwenzeka ngokugcwele ukukhiqizwa, ngakho-ke umthelela webhola lensimbi awukwazi ukukhiqiza ngokugcwele ukucubungula, ngakho-ke awugqokile. Amandla wethonya lepuleti lokugaya elimnandi lokugaya lincane, futhi ukumelana nokugqokwa kwensimbi ephezulu yemanganese akunakudlalwa.
I-3. Ukukhetha izinto ezingavinjelwe ukugqokwa kokugaya ikhanda lekhanda lokugcina ipuleti, ipuleti lensimbi kanye neplanethi yegatsha
.
Ibhodi yedolobhana lekhanda lokugaya lisekupheleni kokudla komgqomo wama-coarse, ubukhulu obuphakathi kwezihlayikhali bomzimba wokugaya bukhulu, futhi umthelela oseceleni webhola lokugaya futhi okuqukethwe kukhulu, okuyindlela yokugqoka ye-greating umthelela wokugqoka futhi wenezelwe ngokusika. Ngakho-ke, ipuleti lokugaya lekhanda lokugaya kufanele likhethe izinto ezinobunzima obuphakeme kanye nokumelana nomthelela, ubunzima obuphezulu nokusika ukumelana. Ngaphambi kokusetshenziswa kwensimbi ephezulu yemanganese, ngoba umthelela awanele ukwenza kube lukhuni lwayo, ubulukhuni bungafinyelela kuphela nge-HB 350, ngokugqokwa kokuguguleka kwezinto ezibonakalayo kuphansi, impilo yenkonzo iphansi. Uma ukhetha i-carbon ephakathi nendawo ye-alloy yensimbi yokulinganisa ipuleti, Hardness Herc 46-50, Umthelela Fauthness Ak5 J / CM2, Impilo Yesevisi ingaba kabili leyo ngensimbi ephezulu ye-manganese.t
