Indlela ye Ukucima umphezulu wokuxolelwa

Ukucima umphezulu wobushushu yindlela yonyango lobushushu apho umphezulu womsebenzi ushushu ngokukhawuleza kubushushu obucimayo kwaye emva koko upholile ngokukhawuleza, ukuze kuphela umaleko womphezulu ufumane ulwakhiwo olucinywayo, ngelixa icandelo eliphambili ligcina ulwakhiwo ngaphambi kokucima. Ngokuqhelekileyo kusetyenziswa ukufudumeza komhlaba kunye nokucima umlilo. Ukuqina komphezulu ngokubanzi kuyintsimbi yentsimbi yekhabhoni kunye nokuxinana okuphakathi kwe-carbon alloy.

Ukuqiniswa kwe-induction kusetyenziswa umgaqo wokungeniswa kwe-electromagnetic ukwenza i-eddy yangoku enkulu kumphezulu womsebenzi ngokutshintshana yangoku, ukuze umphezulu wobushushu ubushushu ngokukhawuleza, ngelixa undoqo ungafudumali.

Iimpawu zobushushu bendawo yokucoca ubushushu: emva kokucinywa, iinkozo zemartensite ziyacocwa, kwaye ubunzima bomhlaba bungu-2 ~ 3HRC ngaphezulu kokucima okuqhelekileyo. Uluhlu lomphezulu lunoxinzelelo olukhulu lokucinezela okushiyekileyo, olunceda ukuphucula amandla okukhathala; akukho lula ukuvelisa i-deformation kunye ne-oxidative decarburization; Kulula ukuqonda oomatshini kunye noomatshini, kwaye kufanelekile kwimveliso yobuninzi. Emva kokufudumeza ngokungeniswa kunye nokucinywa, ukunciphisa uxinzelelo lokucima kunye nokunciphisa ukukrala, kuyimfuneko ukwenza ubushushu obuphantsi kwi-170 ~ 200 ° C.

Ukucima umlilo kwilangatye yinkqubo apho umphezulu wokuxolela utshiswa msinyane kwinqanaba lobushushu besigaba esingaphezulu kobushushu besigaba sisebenzisa idangatye (ubushushu obuphezulu njenge-3100 ~ 3200 ° C) evutha ngegesi ye-oxyacetylene, elandelwa kukucima nokupholisa .

Iqondo lobushushu elisezantsi lenziwa kwangoko emva kokucinywa, okanye ubushushu benkunkuma yangaphakathi eyenziweyo isetyenziselwa ukuzibamba. Le ndlela inokufumana ubunzima bokuqina obu-2-6 mm, ngezixhobo ezilula kunye neendleko eziphantsi, kwaye kufanelekile kwimveliso enye okanye encinci yebhetshi.
