Yintoni iChromium Carbide Overlay Wear Plate kwaye Kutheni Ingagugi Kakhulu Kunentsimbi Eqhelekileyo?

Kwimizi-mveliso enzima efana nemigodi, isamente, kunye nokuveliswa kombane, ukuguguleka kwezixhobo ngumceli mngeni omkhulu. Izixhobo zentsimbi eziqhelekileyo zihlala ziguguleka ngokukhawuleza, nto leyo ebangela ukuba zingasebenzi rhoqo kwaye zilungiswe ngendlela ebiza kakhulu. Kulapho ke kulapho ziguguleka khona izixhobo.ipleyiti yokunxiba egqunywe yi-chromium carbideKodwa yintoni eyenza ukuba ingagugi kakhulu kunentsimbi eqhelekileyo?

Ukuqonda iPlate yokuNxiba iChromium Carbide Overlay

Ipleyiti yokugquma ye-chromium carbide overlay yinto ekhethekileyo eyenzelwe ukumelana nokuguguleka okugqithisileyo kwiindawo ezirhabaxa. Iqulathe isiseko sentsimbi esiphantsi kwekhabhoni esigqunywe ngomaleko oqinileyo otyebileyo ngamasuntswana e-chromium carbide, ikakhulu i-Cr₇C₃. Ezi carbides zenzeka ngexesha lenkqubo yokuwelda kwaye zisasazwa ngokulinganayo kumphezulu, zibonelela ngokhuseleko olukhethekileyo ekugugulekeni kokutyibilika, ukuchaphazeleka, kunye nokukhukuliseka.

Ngokungafaniyo neepleyiti zentsimbi eziqhelekileyo, ezixhomekeke kuphela kukuqina kwesinyithi esisisiseko, ezi pleyiti zisebenzisa ii-hard alloy phases ezifakwe kwi-matrix, zandisa kakhulu ubomi benkonzo.

Kutheni Isebenza Kakuhle Kungcono Kwintsimbi Eqhelekileyo

1. Ulwakhiwo lweCarbide oluPhezulu

Isitshixo sokumelana nokuguguleka sikwihlobo kunye nokusasazwa kwee-carbides. Intsimbi eqhelekileyo inee-carbides ezisekwe kwisinyithi ezifana ne-Fe₃C, ezithambileyo kwaye ziguguleka lula. Ngokwahlukileyo koko, iipleyiti zokuguguleka ze-chromium carbide zenza ii-carbides eziphezulu ze-chromium ezifana ne-Cr₇C₃ — iikhompawundi ezibonisa amanqanaba obunzima be-HRC 58–65.

Ezi carbides zizinzile kakhulu kwaye ziyamelana nokukrala, ingakumbi phantsi kweemeko zokutyibilika okomileyo okanye ubushushu obuphezulu.

Inyani Eyonwabisayo: Okukhona umlinganiselo we-athomu we-chromium kwi-carbon uphezulu, kokukhona i-carbides izinzile kwaye iqine ngakumbi — into ephambili ekwenzeni ngcono ipleyiti yentsimbi eqhelekileyo engagugiyo.

2. Ulwakhiwo oluNgcono lweMicrostructure

Kwiipleyiti zokuguguleka ezisemgangathweni, i-overlay elukhuni ine-martensitic matrix edityaniswe nomthamo omkhulu wee-carbides ezisasazwe ngokulinganayo. Olu lwakhiwo oludibeneyo luvumela ipleyiti ukuba imelane nokuguguleka okutyibilikayo kunye nokuchaphazeleka okuphakathi, nto leyo eyenza ukuba ibe nokuguquguquka okukhulu.

Nangona kunjalo, ukuba ii-carbides zenzeka ngokungalinganiyo — njengakwizakhiwo ezifana ne-net okanye ecaleni kwemida yeenkozo — ukumelana nokuguguleka kunokuncipha kakhulu. Yiyo loo nto ukucubungula nokulawula kubalulekile.

3. Inkxaso Enzima Yokuwelda Nokwenza Izinto

Ngokungafaniyo neeseramikhi ezibuthathaka okanye intsimbi yesixhobo,iipleyiti zokunxiba ezidityanisiweyoinesiseko sentsimbi esithambileyo esivumela ukuwelda, ukugoba, kunye nokusika okulula — kubandakanya ukusika ngeplasma kunye ne-laser. Oku kuvumela abavelisi ukuba bavelise iimilo ezintsonkothileyo ezifana nee-curved liners, imicu yokuguguleka, kunye nezinto zokwakha ukuze zifakelwe ngokwezifiso.

Izicelo zeHlabathi Lokwenyani: Zisetyenziswa phi ezi Plate?

Ipleyiti yokunxiba egqunywe nge-chromium carbide isetyenziswa kakhulu kwiindawo apho ukuguguleka okuphezulu kuyinto eqhelekileyo yemihla ngemihla:

Ukwemba: Iichuthi zokudlulisa, iihopper,iipleyiti zesikrini

Izityalo zesamente: Iikhowuni zokwahlulahlula, ii-clinker feeders, ii-screw conveyors

Izityalo zamandla obushushu: Iiliner zemill yamalahle, iinkqubo zokuphatha uthuthu

Iifektri zentsimbi: Izityalo zeSinter, iibhini zezinto zokwakha,iichuthi zokukhupha

Kwimeko nganye, ukutshintsha izinto eziqhelekileyo ngepleyiti yokuguguleka ene-chromium eninzi kwandisa ubomi kwaye kunciphisa ukugcinwa okungacwangciswanga.

Ukukhetha ipleyiti yokunxiba efanelekileyo

Xa ukhetha ipleyiti yokunxiba ye-chromium carbide overlay, cinga ngoku:

Ubukhulu kunye nokwakheka kwe-overlay (umz., 4+4mm, 6+6mm, 8+6mm)

Inxalenye yomthamo weCarbide (i-30%+ iyathandwa)

Inkqubo yokuwelda (i-arc engaphantsi kwamanzi kunye ne-arc evulekileyo)

Iimfuno zokusika (iplasma, ilaser)

Kwakhona, soloko uqinisekisa ukuba imveliso iyahlangabezana na nemigangatho yomgangatho efana nokufana kobulukhuni, ulwakhiwo lwe-metallographic, kunye nokumelana nempembelelo.
