Ukuphonononga iSilicon Carbide Wear exhathisa iMibhobho: “IHardcore” uMgcini woThutho lwezoShishino

Kwiimeko zeeworkshops zasefektri, imigodi, okanye ukuhanjiswa kwamandla, kukho uhlobo lombhobho "olungaziwa" unyaka wonke kodwa luthwala uxanduva olunzima - bahlala behambisa imithombo yeendaba kunye neempawu ezinamandla zokukrazula ezifana nesanti, i-slurry, umgubo wamalahle, njl njl. Ukuvela kweimibhobho ye-silicon carbide ekwaziyo ukunxibangokuchanekileyo kukusombulula le ngxaki yemizi-mveliso, ibe ngumgcini "ongundoqo" kwiindawo zothutho ezinzima.
Yintoni umbhobho wesilicon carbide ukunxiba?
Ukubeka nje ngokulula, imibhobho ye-silicon carbide enganyangekiyo yimibhobho yothutho eyenziwe ngokudibanisa i-silicon carbide njengeyona nto ingundoqo enganyangekiyo ngemibhobho yentsimbi (enjengemibhobho yentsimbi) ngeenkqubo ezikhethekileyo.
Omnye unokubuza, yintoni i-silicon carbide? Yimathiriyeli engenziwanga ngokwendalo engeyiyo eyentsimbi enobunzima obuphezulu, okwesibini kuphela kwidayimane. Uninzi lweesanti kunye namavili okugaya esiwabona kubomi bemihla ngemihla zenziwe ngesilicon carbide. Ukusebenzisa 'ingcaphephe engagugiyo' ukwenza ulutya lwangaphakathi lwemibhobho ngokwendalo lunokubanika ukuxhathisa okunamandla okunxiba.

Xa kuthelekiswa nemibhobho yentsimbi eqhelekileyo yesiqhelo kunye nemibhobho yamatye, inzuzo engundoqo ye-silicon carbide imibhobho enganyangekiyo ilele "kuzo zombini ukulungiswa kwangaphakathi nangaphandle": i-silicon carbide layer yangaphakathi inoxanduva lokuxhathisa ukhukuliseko kunye nokuguga kwe-medium, ngelixa i-metal yangaphandle iqinisekisa amandla onke kunye namandla oxinzelelo lombhobho. Ukudibaniswa kwezi zibini akusombululi kuphela ingxaki yokuxhatshazwa kokugqoka, kodwa kwakhona kuthathela ingqalelo ukhuseleko kunye nokuthembeka kokusetyenziswa kwamashishini.
Kutheni 'inokumelana' neemeko ezingqongileyo ezirhabaxa?
Ukuqina kwemibhobho ye-silicon carbide enganyangekiyo ivela kwiimpawu ze-silicon carbide ngokwayo:
Ukumelana nokunxiba okunamandla: Njengoko kukhankanyiwe ngaphambili, i-silicon carbide inobunzima obuphezulu kakhulu, kwaye ukunxiba kwayo kumphezulu kucotha kakhulu ebusweni bokukhukuliseka kwexesha elide ukusuka kwimithombo yeendaba yegranular efana ne-slurry kunye nesanti. Xa kuthelekiswa nemibhobho yentsimbi eqhelekileyo, ubomi babo benkonzo bunokwandiswa amaxesha amaninzi okanye nangaphezu kweshumi, ukunciphisa kakhulu ukuphindaphindeka kunye neendleko zokutshintshwa kwemibhobho.
Ukumelana nobushushu obuphezulu kunye nobuphantsi kunye nokuxhathisa ukubola: Ukongeza kokunganyangeki, i-silicon carbide iyakwazi ukuziqhelanisa noluhlu olubanzi lwamaqondo obushushu, kwaye inokusebenza ngokuzinzileyo kwiimeko ezisusela kumashumi amashumi amaqondo obushushu ukuya kumakhulu amaqondo obushushu. Kwangaxeshanye, ikwanazo nokuchasana kakuhle nemithombo yeendaba ezonakeleyo ezifana ne-asidi kunye ne-alkali, eyenza ukuba “ikwazi” kwiimeko zothutho ezintsonkothileyo kumashishini afana neekhemikhali kunye ne-metallurgical.
Ubuchule bokuhambisa obuzinzile: Ngenxa yomgangatho ogudileyo we-silicon carbide lining, ukuxhathisa okuphakathi okuqukuqela kumbhobho kuphantsi, nto leyo eyenza ukuba kungabi lula ukuvaleka. Oku akuqinisekisi nje ukusebenza kakuhle kwezothutho, kodwa kunciphisa ixesha lokuphumla elibangelwa kukucoca imibhobho.
Ibonisa phi izakhono zayo?
Nangona ivakala "njengengcali", ukusetyenziswa kwemibhobho ye-silicon carbide enganyangekiyo isondele kakhulu kwimveliso kunye nobomi bethu:
Kwimigodi kunye namashishini e-metallurgical, isetyenziselwa ukuthutha i-slurry yamaminerali ukusuka kwimigodi kunye nenkunkuma eseleyo ukusuka ekunyibilikeni, kwaye iphantsi kokugqoka kunye nokukrazula okuvela kwi-high concentration ye-particulate media;
Kwishishini lamandla, ngumbhobho obalulekileyo wokuthutha umgubo wamalahle kwizityalo zamandla obushushu, ukuqinisekisa unikezelo oluzinzileyo lwepetroli yebhoyili;
Kwizinto zokwakha kunye namashishini ekhemikhali, inokuthutha izinto eziluhlaza zesamente, izinto ezisetyenziselwa iikhemikhali, njl., Ukujongana nokuguga kunye nokugqwala okuncinci kweendaba ezahlukeneyo.
Kunokuthiwa kuyo nayiphi na indawo yoshishino efuna ukuthuthwa kweendaba ngokuxhathisa okuqinileyo kunye neemeko zokusebenza ezinzima, ubukho bemibhobho ye-silicon carbide enganyangekiyo ingabonwa. Inika iziqinisekiso ezibalulekileyo zokusebenza okuqhubekayo kunye nokusebenza ngokufanelekileyo kwemveliso yemizi-mveliso kunye nokusebenza kwayo "i-hardcore", kwaye ibe yinxalenye eyimfuneko kwiinkqubo zanamhlanje zokuhanjiswa kwemizi-mveliso.
