Indima yeKhemikhali nganye

Ikhabhoni (C)

Umxholo wekhabhoni kwi-SKD11 uphakathi kwe-1.40% kunye ne-1.60%, nto leyo eyenza ukuba ibe yintsimbi enekhabhoni ephezulu. Ikhabhoni ephezulu yonyusa ubulukhuni obunokubakho emva konyango lobushushu, nto leyo ephucula ukumelana nokuguguleka kunye nomthamo wokuthwala umthwalo. Nangona kunjalo, ikhabhoni eninzi inokwenza intsimbi ibe buthathaka, ngoko ke i-SKD11 igcina ibhalansi efanelekileyo kwimisebenzi ebandayo.

I-Chromium (Cr)

Njengoko amanqanaba e-chromium ephakathi kwe-11% ukuya kwi-13%, i-SKD11 iwela kudidi lweentsimbi ezine-chromium ephezulu. I-Chromium inika ukumelana nokugqwala, iphucula ukuqina, kwaye yenza ii-carbides ze-chromium eziqinileyo ezikhuthaza kakhulu ukumelana nokuguguleka. Lo mxholo we-chromium ephezulu ukwaqinisa ulwakhiwo lwentsimbi ngexesha lonyango lobushushu.

I-Molybdenum (Mo)

I-Molybdenum yongezwa ukusuka kwi-0.80% ukuya kwi-1.20% ukomeleza ukuqina nokuthintela ukuqhekeka. Ikwanceda ekuqineni kwesibini ngexesha lokufudumala, okwenza i-SKD11 ifaneleke kwizixhobo ezifuna ukumelana nokuguguleka okuphezulu kumanqanaba aphezulu obunzima.

I-Vanadium (V)

Nangona zifumaneka ngobuninzi obuncinci (0.20% ukuya kwi-0.50%), ivanadium idlala indima ebalulekileyo ekucoceni isakhiwo sengqolowa nasekuphuculeni ukumelana nokuguguleka. Yenza iivanadium carbides, eziqinileyo kakhulu kwaye zinceda ukugcina ubukhali bomphetho kwizixhobo zokusika.

IManganese (Mn)

Umxholo weManganese kwi-SKD11 uphakathi kwe-0.20% ukuya kwi-0.60%. Uphucula ukuqina kunye namandla okutsalwa, ngelixa usebenza njenge-deoxidizer ngexesha lokuveliswa kwentsimbi.

I-Silicon (Si)

I-silicon, nayo ephakathi kwe-0.20% kunye ne-0.60%, iyomeleza intsimbi ngokuqinisa isisombululo esiqinileyo kwaye iphucula ukumelana ne-oxidation ngexesha lonyango lobushushu. Njenge-manganese, ikwasebenza njenge-deoxidizing agent.

I-Phosphorus (P) kunye ne-Sulfur (S)

I-phosphorus ne-sulfur zihlala zigcinwa ziphantsi kangangoko, zihlala zingaphantsi kwe-0.030%. Nangona ubungakanani obuncinci bunokuphucula ukusebenza kakuhle komatshini, amanqanaba agqithisileyo anokunciphisa ukuqina kwaye abangele ukuqhekeka.

Impembelelo yoBume beeKhemikhali kwiipropati zeeMechanical

Indlela ethile yokwenza iikhemikhali ye-SKD11 imisela ukusebenza kwayo koomatshini:

  • Ubunzima obuphezulu– Ifezekiswe ngamanqanaba aphezulu ekhabhoni kunye ne-chromium, okuvumela ubulukhuni ukuya kuthi ga kwi-HRC 60 emva konyango lobushushu.

  • Ukumelana nokunxiba okugqwesileyo– I-Chromium kunye ne-vanadium carbides zibonelela ngokhuseleko lokuguguleka oluhlala ixesha elide kwizixhobo zokusika nokwenza.

  • Uzinzo olunemilinganiselo– Izinto ezidibanisa i-alloying ziqinisa ulwakhiwo lwe-microstructure, ziqinisekisa ukuphambuka okuncinci ngexesha lonyango lobushushu.

  • Ukuqina Okulungileyo– I-Molybdenum ithintela ukuqhekeka, ilungelelanisa ubulukhuni kunye nokumelana nokuchaphazeleka.

Olu didi lweempawu luvumela i-SKD11 ukuba isebenze kakuhle kakhulu ekusikeni iidayi, ukunyathela, kunye nezinye iindlela zokusebenzisa uxinzelelo oluphezulu.

Impembelelo Yonyango Lobushushu Kwindlela Yokuziphatha Kweekhemikhali

Unyango lobushushu lubalulekile kwi-SKD11 njengoko luvuselela amandla okwakheka kweekhemikhali zayo. Inkqubo eqhelekileyo ibandakanya:
