Isishwankathelo seendlela ezilishumi eziqhelekileyo zokucima umatshini wokucima rhoqo (2)

6. Indlela yokucima iCompound

Indlela yokucima i-Compound: okokuqala vala i-workpiece ukuya ngaphantsi kukaNks ukufumana i-martensite kunye neqhezu lomthamo we-10% ~ 30%, kwaye emva koko i-isothermally kwindawo ephantsi ye-bainite ukufumana i-martensite kunye ne-bainite isakhiwo se-workpiece enecandelo elikhulu elinqamlezayo. Isixhobo se-alloy workpiece yentsimbi.

Zisixhenxe, ngaphambi kokupholisa isothermal indlela yokucima

Indlela yokucima i-isothermal yangaphambi kokupholisa: ekwabizwa ngokuba kukufudumeza kwe-isothermal quenching, iindawo ziqala ukupholisa kwibhafu kunye nobushushu obuphantsi (omkhulu kunoNksk), kwaye emva koko idluliselwe kwibhafu kunye nobushushu obuphezulu ukwenza i-austenite iguquke kwi-isothermal. Ifanelekile kwiindawo zetsimbi ezinobunzima obunzima okanye i-workpieces enkulu ekufuneka i-austempered.

Esibhozo, ukulibaziseka ukupholisa indlela yokucima

Indlela yokucima ukupholisa ilibazisekile: Amalungu aqala ukupholiswa emoyeni, emanzini ashushu, kunye nebhafu yetyuwa ukuya kumaqondo obushushu angaphezulu kancinane kune-Ar3 okanye i-Ar1, emva koko ukucinywa kwe-single-medium kuyenziwa. Ihlala isetyenziselwa iindawo ezineemilo ezintsonkothileyo kunye neenxalenye ezinomahluko omkhulu wobunzima kunye neemfuno zoguqulo oluncinci.

9. Indlela yokucima kunye nokuzibamba

Ukucima indlela yokuzibamba: fudumeza zonke izinto zokusebenza eziza kucutshungulwa, kodwa untywilisele kuphela indawo efuna ukuqina (ngokuqhelekileyo inxalenye esebenzayo) kulwelo lokucima ukupholisa, kwaye uyikhuphe emoyeni xa inxalenye engabhalwanga inyamalala. Inkqubo yokucima kunye nokupholisa okuphakathi. Indlela yokucima ukuzibamba isebenzisa ubushushu obungapholiswanga ngokupheleleyo kumbindi ukuze budluliselwe kumphezulu ukucaphuka umphezulu. Ngokuqhelekileyo isetyenziselwa izixhobo ezinempembelelo ezifana neetshizi, iipuntshi, iihamile, njl.

Ishumi, indlela yokutshiza yokucima

Indlela yokucima i-Jet: Indlela yokucima i-jetting water flow to workpiece, ukuhamba kwamanzi kunokuba kukhulu okanye kuncinci, kuxhomekeke kubunzulu obufunekayo bokucima. Indlela yokucima isitshizi ayifaki ifilimu yomphunga phezu kwendawo yokusebenza, eqinisekisa ukuba ungqimba olunzulu oluqinileyo kunokuba lucime emanzini aqhelekileyo. Isetyenziswa ikakhulu ukucima umphezulu wendawo.
