Ngaba iSixhobo seNkunkuma siQinisekisa ukuGqwala?

Intsimbi yezixhobo ludidi olukhethekileyo lweentsimbi ze-alloy ezenzelwe ukwenza izixhobo, iidayi, iimold, kunye nezinye izixhobo zoshishino ezimele zinyamezele uxinzelelo olugqithisileyo, ukukrazuka, kunye nobushushu obuphezulu. Eyaziwa ngokuqina kwayo, ukuqina, kunye nokumelana nokuguguleka, intsimbi yezixhobo ibaluleke kakhulu kumashishini okuvelisa, ukwakha, kunye nobunjineli.

Nangona kunjalo, umbuzo oqhelekileyo uphakama:ingaba intsimbi yesixhobo ayimelani nokugqwala?Impendulo emfutshane ithi hayi. Intsimbi yezixhobo, njengezinye iintsimbi ezininzi, ayimelani nomhlwa ngokwendalo. Nangona inika ukusebenza okuhle kakhulu ngokwamandla nokuqina, ukumelana nomhlwa ayilophawu lwayo oluphambili. Kweli nqaku, siza kuhlola ukuba kutheni intsimbi yezixhobo ingamelani nomhlwa, ukuba ithelekiswa njani neentsimbi ezingenasici, kunye neendlela ezinokusetyenziswa ukukhusela intsimbi yezixhobo ekugqwaleni.

Yintoni iSixhobo seNtsimbi?

Iintsimbi zezixhobo ziintsimbi ze-alloy ezenziwe ngezinto ezifana ne-tungsten, i-molybdenum, i-vanadium, kunye ne-chromium. Ezi zinto ze-alloy ziphucula ubulukhuni, ukumelana nokuguguleka, kunye nokuqina. Intsimbi yezixhobo idla ngokusetyenziselwa oku kulandelayo:

• Izixhobo zokusika ezifana needrill, iimilling cutters, kunye neesarha blades

• Iifa zokunyathela, ukubumba, kunye nokukhupha

• Iimbumba zeplastiki kunye ne-casting

• Izixhobo zoomatshini bemizi-mveliso

• Iimela, iitshizili, kunye nezixhobo ezichanekileyo

Uyilo lwayo lugxileukusebenza koomatshini, hayi ukumelana nokugqwala.

Kutheni iSixhobo seNtsimbi singabi sisiqinisekiso sokugqwala

1. Ukungabikho koMxholo ophezulu weChromium

Ukumelana nomhlwa kwintsimbi kuvela ikakhulu kwi-chromium. Iintsimbi ezingasebenziyo zihlala ziqulathe ubuncinane i-10.5% ye-chromium, eyenza umaleko we-oxide ongasebenziyo okhusela umhlwa. Iintsimbi zezixhobo, nangona zinokuba ne-chromium ethile, zihlala zinamanqanaba aphantsi xa kuthelekiswa nentsimbi engasebenziyo, oko kuthetha ukuba azinakwenza umaleko ofanayo wokukhusela.

2. Umxholo weKhabhoni

Iintsimbi zezixhobo zinomthamo ophezulu wekhabhoni, nto leyo eyonyusa ubulukhuni kodwa inciphisa ukumelana nokugqwala. Iintsimbi ezinekhabhoni eninzi zichaphazeleka lula kukugqwala kwiindawo ezifumileyo okanye ezigqwalisayo.

3. Ukuvezwa kokusingqongileyo

Xa zichatshazelwe kukufuma, ioksijini, ingakumbi iityuwa okanye iiasidi, izixhobo ziyabola. Yiyo loo nto umhlwa udla ngokubonwa kwizixhobo ezisikiweyo, iiblade, okanye ii-die ezingakhuselekanga.

Isixhobo seNtsimbi vs iNtsimbi engenasici

• Isixhobo sentsimbi:Yenzelwe ubulukhuni, ukumelana nokuguguleka, kunye nokusebenza kakuhle kumaqondo obushushu aphezulu. Ayimelani nokugqwala ngokwemvelo.

• Yenziwe ngentsimbi eshayinayo:Yenzelwe umxholo ophezulu we-chromium kunye ne-nickel ukuze ikwazi ukumelana nokugqwala, nangona isenokungafikeleli kubunzima obufanayo nobentsimbi yesixhobo.

• Isiphelo:Ukuba ukumelana nokugqwala kubaluleke kakhulu kunokuqina, intsimbi engagqwaliyo inokuba lolona khetho lungcono. Ukuba ubunzima obugqithisileyo kunye nokumelana nokuguguleka kubaluleke kakhulu, intsimbi yezixhobo iyathandwa kodwa ifuna ukukhuselwa kumhlwa.

Iindlela Zokukhusela Intsimbi Yesixhobo Kumhlwa

Nangona izixhobo zentsimbi zingayinyamezeli ingqele, kukho iindlela ezininzi ezinokuyandisa ixesha layo kwaye ziyikhusele ekungcoleni:

1. Iingubo kunye nonyango lomphezulu

• Ukuplata (iNickel, iChrome, okanye iZinc):Yongeza umqobo okhuselayo kwi-oxidation.

• Ukwaleka kwe-Oxide emnyama:Inika ukumelana nokugqwala okuncinci kwaye inciphisa ukukhanya.

• I-PVD kunye ne-Nitriding:Ukuqina komphezulu kunye neengubo zokukhusela ziphucula ukuguguleka kunye nokumelana nokugqwala.

2. Ioyile kunye nee-Lubricants

Ukusebenzisa ioyile, igrisi, okanye izitshizi zokukhusela kuthintela ukudibana komswakama, nto leyo enciphisa kakhulu ukwakheka komhlwa.

3. Ugcino Olufanelekileyo

Izixhobo mazigcinwe kwindawo eyomileyo enomswakama olawulwayo. Izinto zokucoca ulwelo kunye nezinto zokuthintela ukugqwala zingasetyenziswa kwiibhokisi zokugcina okanye kwiindawo zokugcina impahla.

4. Isigqubuthelo Esingenasici

Kwezinye iimeko, izixhobo zentsimbi zinokugqunywa ngeengqimba zentsimbi engagqwaliyo ukuze kudityaniswe ubulukhuni kunye nokumelana nokugqwala.

5. Ukugcinwa rhoqo

Ukucoca nokuhlola rhoqo kuqinisekisa ukuba naziphi na iimpawu zokuqala zokugqwala zinokulungiswa ngaphambi kokuba zisasazeke.

Iintlobo zeZityeli zeThuluzi kunye nokuziphatha kwazo kokubola

Ukuqinisa Amanzi (Uthotho lwe-W)

Azimelani nokugqwala, kuba azinazo izinto ezibalulekileyo zokudibanisa ukuze zikhusele ukugqwala.

Iintsimbi Ezisebenza Ngobushushu (Uthotho lwe-O, A, D)

Ingcono ukumelana nokuguguleka kodwa isenomngcipheko wokugqwala ukuba ayikhuselekanga.

Iintsimbi Ezishushu (Uthotho lwe-H)

Isebenza kakuhle kumaqondo obushushu aphezulu, kodwa ayenzelwanga ukumelana nokugqwala kwiindawo ezidlakadlaka.

Iintsimbi ezikhawulezayo (uthotho lwe-M kunye no-T)

Iqulethe izinto ezininzi zokudibanisa, ezibonelela ngokumelana nokugqwala okuphuculweyo kancinci, kodwa azikwazi ukumelana nokugqwala.

Iintsimbi ezixhathisa ukuTshatyalaka (S-Series)

Iqinile kwaye ayichaphazeleki kodwa ifuna iindlela zokuzikhusela kumhlwa.

Izicelo apho ukuxhathisa umhlwa kubaluleke kakhulu

Kwimizi-mveliso apho ukugqwala kuyingxaki, intsimbi yezixhobo isenokungabi lolona khetho lulungileyo ngaphandle kokuba ikhuselwe ngokufanelekileyo. Umzekelo:

• Izicelo zaseLwandle:Ukufuma okuphezulu kunye nokuvezwa kwetyuwa kufuna izixhobo ezinganyangekiyo okanye ezigqunywe ngokukodwa.

• Ukulungiswa kokutya:Ifuna intsimbi engagqwaliyo ukuze icoceke kwaye ikwazi ukumelana nokugqwala.

• Ukucubungula iikhemikhali:Kusetyenziswa ii-alloys ezingenasici okanye ze-nickel endaweni yeentsimbi zezixhobo ukumelana neekhemikhali ezirhabaxa.

Ukubaluleka Kweshishini Kwentsimbi Yezixhobo Ezikhuselweyo Ngomhlwa

Nangona intsimbi yezixhobo ingangeni mvuthuluka, ihlala iyeyona nto ikhethwayo kwizixhobo kwaye iyafa kuba ukugqwala kunokulawulwa ngamanyathelo okuthintela. Ngokusebenzisa iipeyinti zokukhusela kunye nokugcina ukuphathwa ngokufanelekileyo, intsimbi yezixhobo inokubonelela ngokusebenza ixesha elide kwizicelo ezibalulekileyo.

Indima yabaThengisi abanokuthenjwa

Xa ukhetha izixhobo zentsimbi, kubalulekile ukufumana kubathengisi ababonelela ngamabakala aqinisekisiweyo kunye nesikhokelo malunga nokukhusela ukugqwala.i-sakysteelukubonelela ngeendidi ezahlukeneyo zeentsimbi zezixhobo ezinonyango olufanelekileyo lobushushu kunye neendlela zokugqiba umphezulu ukuze kuphuculwe ukusebenza. Ngokusebenzisana nei-sakysteel, amashishini afumana ukufikelela kwizisombululo zentsimbi yezixhobo ezikumgangatho ophezulu ezilungelelanisa ubulukhuni, ukuqina, kunye nolawulo lokugqwala.

Isiphelo

Intsimbi yezixhobo ayimelani nomhlwa. Nangona igqwesile ngokuqina, ukumelana nokuguguleka, kunye namandla obushushu aphezulu, ukumelana kwayo nomhlwa kulinganiselwe xa kuthelekiswa neentsimbi ezingenasici. Nangona kunjalo, ngokugquma okufanelekileyo, ukuthambisa, ukugcinwa, kunye nokugcinwa, ukwakheka komhlwa kunokunciphisa, ukuqinisekisa ukuba intsimbi yezixhobo inika ukusebenza okuthembekileyo.

Kwizicelo ezifuna ubulukhuni obuphezulu kunye nokuqina, intsimbi yesixhobo ihlala iyeyona ndlela ilungileyo, ukuba kusetyenziswa amaqhinga okukhusela umhlwa afanelekileyo. Kwimizi-mveliso apho ukumelana nokugqwala kuyinto ephambili, intsimbi engagqwaliyo okanye ezinye ii-alloys zinokufaneleka ngakumbi. Ekugqibeleni, ukuqonda amandla kunye nemida yentsimbi yesixhobo kunceda amashishini ukuba enze ukhetho lwezinto ezinolwazi ukuze asebenze kakuhle kwaye athembeke ixesha elide.
