Iimpawu zokufudumeza kwentsimbi ecinyiweyo ukufudumeza iziko

Isakhiwo sokufudumeza ngokukhawuleza isinyithi esiqinileyo sihluke kwintsimbi yendabuko, kwaye inkqubo yokufudumala ibonisa ezi mpawu zilandelayo.

Unyango olushushu lwe-induction yokufudumeza isithando somlilo alufanelekanga ukufudumala kweqondo eliphantsi ukufumana isakhiwo se-martensite. Inkqubo yokufudumala yendabuko inokuqhutyelwa kwiqondo lokushisa eliphezulu (500 ~ 650 ° C), ukushisa okuphakathi (350 ~ 500 ° C) kunye nokushisa okuphantsi (150 ~ 250 ° C). C) Iintlobo ezintathu zonyango lokuthomalalisa. I-furnace yokufudumeza i-induction ifanelekile kuphela kwiqondo lokushisa eliphezulu kunye neqondo lokushisa eliphakathi, alifanelekanga ukufudumala kweqondo eliphantsi. Oku kungenxa yokuba xa i-furnace yokufudumeza i-induction iqhutyelwa kwiqondo lokushisa kwe-150 ~ 250 ° C, kunzima ukuqonda ukushisa kwe-diathermy uniform yezinto zetsimbi. Ngenxa yobushushu obuphantsi bokufudumeza, umahluko omncinci wobushushu phakathi komphezulu kunye neziko, kunye nesantya esicothayo sokuhambisa ubushushu, kuthatha ixesha elide ukuba i-diathermy ilingane ubushushu, nto leyo ekhokelela ekunciphiseni ukusebenza kakuhle kwe-thermal. Ngoko ke, unyango olushushu lwe-furnace yokufudumeza i-induction alukwazi ukufumana isakhiwo se-martensite edibeneyo, kwaye ubushushu bokufudumala buphezu kwendawo. Okwangoku, iqondo lobushushu lobushushu le-induction yokufudumeza iziko locingo lwentsimbi yasentwasahlobo linokufikelela kuma-400°C.

I-furnace yokufudumeza i-induction inobushushu obuphezulu, iqondo elikhulu lokufudumala, kunye nexesha elifutshane lokubamba. Ukuze ukhawulezise ukuguqulwa kwesakhiwo kunye nokunciphisa ixesha lokubamba, kwaye uqonde injongo yokufudumala, ukufudumala kweqondo lokushisa kwesithando sokufudumala somlilo kuphezulu kunobushushu bokufudumala bokufudumala kwendabuko. Itheyibhile ye-4-23 ibonisa umphumo wokuthelekisa inkqubo yokufudumeza yokufudumala kwesithando somlilo ukunyusa ubushushu bokufudumala kunye nokunciphisa ixesha lokubamba kunye nenkqubo yokufudumeza kwendabuko kunye nokufudumala. Idatha kwiThebhile 4-23 ibonisa ukuba ukuze ufumane i-35CrM efanayo. Ukuqina kokuqina kwentsimbi, iqondo lobushushu lokufudumeza lokungeniswa liphezulu ngokuhambelanayo kunobushushu bemveli kunye nobushushu bobushushu nge-190 ~ 250 ° C. Ukwandisa iqondo lobushushu ngokutshintshiselana ngokunciphisa ixesha lokubamba i-teering, lifutshane ukusuka kwi-1800 ukuya kwi-40s. Oku kubonisa iimpawu zonyango olukhawulezayo lokushisa kwii-furnaces zokufudumala kwe-induction. Isizathu sokuba ukufudumala kwesithando sokufudumala kwe-induction kungatshintshwa yiqondo lokushisa ikakhulu ngenxa yokuba ubushushu yiyona nto iphambili yokuqhuba ukukhuthaza ukuguqulwa kwesakhiwo. Ukwandisa ukushisa kunokukhawuleza ukuguqulwa kwesakhiwo, esisebenza ngakumbi kunokwandisa ixesha lokubamba. Esinye isizathu kukuba ukuzinza kwesakhiwo se-martensite ye-induction yokufudumeza intsimbi ecinyiweyo imbi ngaphezu kwesakhiwo se-martensite sendabuko, kwaye kulula ukuyiguqula.

Itheyibhile 4-23 Ubudlelwane phakathi kobulukhuni kunye nobushushu bobushushu bentsimbi ye-35CrMo yacinywa kwaye inomsindo

( 3) Ukuzinza kwesakhiwo sokufudumala kwesithando sokufudumala kwe-induction sibi. Ngenxa yokuba i-furnace yokufudumeza i-induction isebenzisa indlela yokushisa ephezulu ngaphandle kokugcinwa kobushushu, ukuguqulwa kwesakhiwo akwanele, ngoko ukuzinza kwayo akubi. Le ndlela yokufudumala ayinakusetyenziswa kwiintsimbi ezifuna ukusebenza kwexesha elide kumaqondo okushisa aphezulu, njengeentsimbi eziphantsi kwe-alloy for boilers station stations.
