Ukuthuthukiswa kwenqubo yokwelapha ukushisa kwensimbi ye-high grade chain 23MnNiMoCr54
Ukwelashwa kokushisainquma ikhwalithi kanye nokusebenza kwensimbi ye-round link chain, ngakho-ke inqubo yokwelashwa yokushisa enengqondo futhi ephumelelayo iyindlela ephumelelayo yokuqinisekisa ukuzinza okuhle kwensimbi ye-high-grade chain.
Inqubo yokwelashwa kokushisa kwe-23MnNiMoCr54 yensimbi ye-high grade chain
Indlela yokushisa yokungeniswa kwe-frequency ephakathi inezici zesivinini sokushisa okusheshayo kanye ne-oxidation encane, engavumelani nje nokukhiqizwa okuluhlaza kwamanje, kodwa futhi ifinyelela izinkomba ezithile zamandla eketango lensimbi eyindilinga kanye nokuqina. Inqubo ethize yokwamukela ukwelashwa kokushisa kokungeniswa kwemvamisa emaphakathi iwukusebenzisa isithando somlilo esiqhubekayo sokungeniswa kwefrikhwensi emaphakathi yemishini yokushisa yokungeniswa kwamandla aphezulu kuqala, ukuze kubonwe ukwahlukaniswa kweketango lensimbi eliyindilinga lokucisha nokufudumeza. Izinga lokushisa lokucisha kanye nelokushisa ngaphambi kokuba iketango lifakwe emlilweni lilawulwa ngokuqinile ukulinganisa izinga lokushisa le-infrared. Ngokusebenzisa ukuhlolwa ngokusebenza, kutholakala ukuthi indawo yokupholisa yokucisha nokushisa amanzi, izinga lokushisa lamanzi lilawulwa ngaphansi kuka-30 ℃. Amandla okushisa okucisha kufanele alawulwe phakathi kuka-25-35kw, ijubane leketanga kufanele lilawulwe ku-8-9hz futhi izinga lokushisa kufanele lilawulwe phakathi kuka-930 ℃ -960 ℃, ukuze ukuqina kongqimba oluqinile kanye neketango kungahlangabezana nezidingo ezithile zekhwalithi. . Amandla okushisa enqubo yokushisa alawulwa ku-10-20kw futhi izinga lokushisa lilawulwa ku-500 ℃-550 ℃. Isivinini se-chain sigcinwa phakathi kuka-15 no-16Hz.
(1) Esikhathini sokuqala sokwenzaround steel link chain, indlela yokwelapha ukushisa isithando somlilo esikhazimulayo, njengesithando somlilo esijikelezayo. Isithando somlilo se-convection sisetshenziselwa ukushisa. Le ndlela idinga isikhathi eside sokushisa nokusebenza kahle okuphansi, okunye kwakho okudinga iketango elide lokudonsa. Kuyo yonke inqubo yokushisa yeketanga, ngenxa yezinga eliphezulu le-oxidation ebusweni, kunzima ukuthola okusanhlamvu okuhle kakhulu kwe-austenite, okuholela ekugcineni izinga elijwayelekile leketanga lesixhumanisi sensimbi eliyindilinga elikhiqizwa ngaleso sikhathi. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwelashwa kokushisa, indlela yokushisa yokungenisa imvamisa emaphakathi eyakhiwe esigabeni sakamuva isetshenziswa kabanzi, futhi ikhwalithi yokwelashwa kokushisa kochungechunge lwezixhumanisi zensimbi eyindilinga iye yathuthukiswa kakhulu.
(2) I-chain tempering technology, ukusetshenziswa kokuqala kokushisa okufanayo kokushisa, okwamanje. ukuthuthukiswa kokuzinza kakhulu izinga lokushisa elihlukanisiwe lemvamisa emaphakathi kanye nezinga lokushisa elifanayo kanye nokwehluka kwezinga lokushisa. Okubizwa ngokuthi ukushisa okufanayo kokushisa ukucabangela ukuthi ukuqina kwengxenye ngayinye ye-chain link kuyafana ngemva kokushisa, kodwa i-chain link yenziwa nge-welding. Uma izinga lokushisa lokushisa liphansi kakhulu, i-welding joint iphuka kalula, futhi ubulukhuni be-chain link buphakeme, ukungqubuzana phakathi kwengaphandle lengalo eqondile kanye nokushintsha okuphakathi kwesithumeli nakho kulula kakhulu ukukhiqiza imifantu. Uma izinga lokushisa lokushisa liphansi, ukuqina kweketango nakho kungancishiswa. Ukushisa okuhlukile kokushisa kwamukela ukushisa kwe-induction, okulungele kakhulu izimo zokushisa zeketanga, okungukuthi, phezulu kwehlombe leketango linobunzima obuphezulu nokumelana nokugqoka, futhi ingalo eqondile inobulukhuni obuphansi kanye nokuqina okuhle. Le ndlela yokwelapha ukushisa ingathuthukisa kakhulu ikhwalithi yeketanga.
