Ukubunjwa kweMichiza kunye neMicrostructure
Ukwakhiwa kweekhemikhali zemidiya ephezulu yokugaya i-chrome yinto ebalulekileyo echaphazela kakhulu ukusebenza kwayo kwizicelo ezahlukeneyo zoshishino. Amacandelo aphambili ale mithombo yeendaba yokusila abandakanya i-carbon, i-chromium, kunye nezinye izinto ezidibeneyo ezifana ne-manganese, i-molybdenum, kunye ne-nickel. Phakathi kwezi, umxholo wechromium, osuka kwi-10% ukuya kwi-30%, ubaluleke ngakumbi njengoko udlala indima ebalulekileyo ekwandiseni ukwakheka kweekhabhide eziqinileyo ngaphakathi kwemathiriyeli. Olu qulunqo lwe-carbide luyimfuneko ekuphuculeni ukunyanzeliswa kokugqoka kunye nokuqina, ngaloo ndlela ivumela imidiya yokusila ukuba inyamezele iimeko ezinzima ezidibana nazo ngexesha lemisebenzi yokugaya.
I-microstructure yemidiya yokusila, echatshazelwa ngokugqithiseleyo kukubunjwa kweekhemikhali kunye nenkqubo yokunyanga ukushisa, idlala indima ebalulekileyo ekunqumeni iipropati zayo zonke kunye neempawu zokusebenza. I-microstructure elungelelanisiweyo equka i-martensite, i-austenite egciniweyo, kunye ne-carbides inqweneleka kakhulu ekufezekiseni ukusebenza kakuhle. Ukusabalalisa kunye ne-morphology yezi zigaba zichaphazela ngokuthe ngqo iimpawu ezibalulekileyo ezifana nobunzima, ukuqina, kunye nokumelana nokugqoka, okuyimfuneko ekusileni okusebenzayo.
Iinkqubo zokunyanga ukushisa, kubandakanywa ukucima kunye nokufudumala, ziqeshwe ngokucwangcisiweyo ukufezekisa i-microstructure efunwayo kunye neempawu zomatshini weendaba zokugaya. Ngethuba lenkqubo yokucima, izinga lokupholisa lilawulwa ngokucokisekileyo, njengoko lichaphazela kakhulu ukubunjwa kwe-martensite kunye nokugcinwa kwe-austenite. Ukulandela ukucima, ubushushu bobushushu bukwakhethwa ngononophelo ukukhulula uxinzelelo lwangaphakathi kunye nokucokisa i-microstructure ngakumbi. Unyango olufanelekileyo lobushushu luqinisekisa i-microstructure ene-homogeneous kunye ne-carbides esasazwa ngokufanayo, enegalelo ekuphuculeni ukuxhathisa ukunxiba kunye nokusebenza ngokubanzi. Ngokulungisa zombini ukubunjwa kweekhemikhali kunye neenkqubo zokunyanga ukushisa, abavelisi banokuvelisa imidiya ephezulu yokugaya i-chrome ezihlangabezana neemfuno ezibangwayo zezicelo ezahlukeneyo zemizi-mveliso, ekugqibeleni zikhokelela ekuphuculeni ukusebenza kakuhle kunye neendleko ezifanelekileyo ekusebenzeni.
IiPropati zeNdawo kunye neNkqubo yokuVelisa
Iimpawu ezibonakalayo zemidiya ephezulu yokusila i-chrome, kubandakanywa ubungakanani, imilo, kunye neempawu zomphezulu, zinempembelelo enkulu ekusebenzeni kwabo kokusila. Ubungakanani beendaba zokugaya zikhethwa ngokusekelwe kwisicelo esithile kunye nobukhulu obufunwayo bezinto ezisemhlabeni. Imithombo yeendaba emincinci iyasebenza kakhulu ekusileni kakuhle, ngelixa imidiya emikhulu ifanelekile kwimisebenzi yokusila erhabaxa.
Ubume beendaba zokusila buchaphazela nokusebenza kwayo. Iibhola zeSpherical zezona fom zixhaphakileyo, ezibonelela ngokuqukuqela okuhle kunye nokunxiba okufanayo. Nangona kunjalo, i-cylpebs (i-cylindrical pellets) ifumana ukuthandwa kwizicelo ezithile ngenxa yokwanda kwendawo kunye nokukwazi ukuphucula ukugaya.
Inkqubo yokwenziwa kwe imidiya ephezulu yokugaya i-chrome ibaluleke kakhulu ekuqinisekiseni umgangatho kunye nokusebenza kwayo. Ukuphosa yeyona ndlela iphambili esetyenziswayo, ngobuchule obufana nokubunjwa kwesanti, ukubunjwa kwesinyithi, kunye nokuphosa okuphakathi kuyasetyenziswa. Inkqubo yokuphosa ichaphazela isakhiwo sangaphakathi, i-porosity, kunye nomgangatho ophezulu weendaba. Ubuchwephesha bokuphosa obuphezulu kunye namanyathelo okulawula umgangatho kubalulekile ukuvelisa imidiya yokugaya ephezulu kunye neepropati ezihambelanayo.
Iindlela zonyango zomphezulu, ezinje ngokukroba okanye ukuqina komphezulu, zinokusetyenziselwa ukomeleza ukuxhathisa ukunxitywa kunye nokuqina kwempembelelo yemithombo yeendaba yokusila. Olu nyango luguqula iimpawu zomphezulu, ludala i-compressive layer yoxinzelelo oluphucula ukuqina kwemidiya kunye nokuchasana nokusasazwa kokuqhekeka.
Iimeko zokuSebenza kunye neeParamitha zeMill
Ukusebenza kwe imidiya ephezulu yokugaya i-chrome iphenjelelwa kakhulu ziimeko zokusebenza kunye neeparamitha zokugaya apho zisetyenziswa khona. Izinto ezinje ngesantya sokusila, intlawulo yebhola, kunye nokuxinana kodaka kunempembelelo enkulu ekusebenzeni kakuhle kokusila kunye nesantya sokunxiba semithombo yeendaba.
Isantya sokugaya sichaphazela intshukumo yemidiya yokusila kunye nokudluliselwa kwamandla kwizinto ezisemhlabeni. Ukusebenza ngesantya esiphezulu kuqinisekisa i-cascading esebenzayo kunye ne-cataracting yeendaba, ukwandisa ukusebenza kakuhle kokusila ngelixa unciphisa ukunxiba. Isantya esibalulekileyo, esisisantya sethiyori apho i-media yokusila iya kuba yi-centrifuge, iyipharamitha ebalulekileyo ekunqumeni isantya esiphezulu sokusebenza.
Intlawulo yebhola, okanye umthamo wemidiya yokugaya kwi-mill, ichaphazela amandla okugaya kunye nokusebenza kakuhle. Intlawulo yebhola efanelekileyo iqinisekisa ngokwaneleyo imidiya-to-media kunye ne-media-to-material contact ngelixa ivumela indawo eyaneleyo yokuhamba kwezinto. Ukutshaja kakhulu okanye ukutshaja ilitye lokusila kunokukhokelela ekunciphiseni ukusebenza kakuhle kokusila kunye nokwanda kokunxiba kwemidiya.
Ubuninzi be-Slurry, obubhekiselele kumlinganiselo wezinto eziqinileyo namanzi kwindawo yokusila, zinefuthe kumatshini wokusila kunye nokunxiba kwemidiya. Uxinzelelo oluphezulu lwe-slurry ngokubanzi lukhokelela ekwandeni kokusebenza kokusila kodwa kunokukhokelela kumazinga aphezulu okunxiba kwimidiya. Ukulinganisa ezi zinto zibalulekile ekuphuculeni inkqubo yokusila kunye nokwandisa ubomi bemithombo yeendaba yokusila.
Izinto eziphantsi komhlaba nazo zidlala indima ekusebenzeni kwemidiya ephezulu yokugaya i-chrome. Izinto eziqina kakhulu nezirhaxayo zinokubangela ukuguga okukhawulezileyo, ngelixa izinto ezithambileyo zinokukhokelela kumazinga okusila acothayo. Ukuqonda iimpawu zezinto zokutya kunye nokulungelelanisa iiparamitha zokugaya ngokufanelekileyo kubalulekile ekufezekiseni ukusebenza kakuhle.
Ukuqukumbela, ukusebenza kwemithombo yeendaba ephezulu yokugaya i-chrome ithonywa yintsebenziswano eyinkimbinkimbi yezinto, kubandakanywa ukubunjwa kweekhemikhali, i-microstructure, iipropati ezibonakalayo, iinkqubo zokuvelisa, kunye neemeko zokusebenza. Ngokuqwalasela ngononophelo kunye nokuphucula ezi zinto, amashishini anokuphucula ukusebenza kwawo kokusila, ukunciphisa izinga lokunxiba, kunye nokuphucula imveliso iyonke. Njengoko iteknoloji kunye nophando kule ntsimi luqhubeka luqhubela phambili, sinokulindela uphuculo olongezelelweyo ekusebenzeni kunye nobomi obude bemidiya ephezulu yokugaya i-chrome.
