E le ho ntlafatsa boima ba holim'a metsi le ho apara ho hanyetsa eapeipi e khutlonnetsepa, e ka sebetsoa ka karolo e 'ngoe ea bokaholimo, ke hore, bokaholimo ba lelakabe le hloekileng la mollo, le phahameng, ho thatafala ha maqhubu a lipakeng le kalafo e itseng ea lik'hemik'hale le tse ling tse joalo.Ka kakaretso holimo, ho thatafala ha maqhubu a lipakeng tsa bongata, e futhumatsoa ka mocheso oa 850-950.℃.Ho fanoe ka conductivity ea eona e futsanehileng ea mocheso, kahoo lebelo la ho futhumatsa ha le potlake haholo, ho seng joalo le tla qhibiliha ka likoli tse ling tse timang mapetsong.Litlhoko tsa ho thatafatsa ka induction Rectangular Pipe normalizing matrix mokhatlo o hlophisitsoeng haholo ke pearlite.Metsi a pholileng a spray kapa tharollo e nang le metsi a joala a polyvinyl, mocheso o futhumatsang o ka bang 200-400.℃, boima ba 40-50HRC, boima le ho hanyetsa ho roala ho tiisa hore ho na le sefahleho sa Rectangular Pipe.

Phekolo ea mocheso oa liphaephe tse khutlonnetsepa e boetse e na le melemo e meraro e latelang:

(A) Botsitso bo phahameng ba sebopeho bakeng sa phala e nepahetseng ea khutlonnetsepa, e hlokang ho nepahala ho phahameng, e tlameha ho boloka botsitso ba maemo, ka lebaka leo sekolo se otlolohileng moeeng, sekhahla sa ho pholisa se lieha, ka hona karolo ea austenite e tsitsitse e tla eketsa palo ea ho bolokoa. austenite dinama tse nyenyane tse phala phala, e lokela ho ba batang kalafo;

(B) Fokotsa khopama quenching ka lebaka la elongated lisekoere le khutlonnetsepa tube, kahoo thatafatsa tshebetso habonolo deformed, e lokela ho ka tieo laoloa deformation, mocheso kalafo ke mohato oa bohlokoa ka quenching tshebetso, tshebediso ya polasetiki e be supercooled austenite ka nako e loketseng, e leng mohato o ka sehloohong oa ho etsa bonnete ba hore boemo ba bona ba ho lumellana, e leng se lokelang ho tima bateng e chesang kapa ho otlolla mocheso ka nako e itseng ha ho futhumatsa ho lokela ho fanyehoa holim'a ho futhumatsa, ho fokotsa ho thatafala ha deformation ka oli, bakeng sa terene e nepahetseng e phahameng, ho fokotsa deformation. khase ea nitriding kapa plasma nitriding, joalo-joalo;
