Ukuze kuthuthukiswe ubulukhuni bomphezulu kanye nokumelana nokuguguleka kwe-Amashubhu angunxande angu-16Mn, ukwelashwa kwendawo, njengomlilo womphezulu, ukucima indawo ngesivinini esiphezulu, ukwelashwa ngokushisa ngamakhemikhali, njll. kufanele kwenziwe kumashubhu angunxande. Ngokuvamile, iningi lezindawo ezivame ukuphakama nokuphakathi ziyacinywa, kanti izinga lokushisa lokushisa lingu-850-950 degrees. Ngenxa yokushisa okuphansi, isivinini sokushisa akufanele sibe sishesha kakhulu. Ngaphandle kwalokho, kuzovela imifantu encibilikayo kanye nemifantu yokucima. Ukucima isivinini esiphezulu kudinga ukuthi i-matrix ejwayelekile ibe yi-pearlite. Ukupholisa isixazululo se-water spray noma i-polyvinyl alcohol. Izinga lokushisa lokushisa lingu-200-400 ℃, kanti ubunzima bungu-40-50hrc, okungaqinisekisa ubulukhuni kanye nokumelana nokuguguleka kwe-ipayipi lesikweleubuso.
Amaphuzu abalulekile alandelayo kufanele aqashelwe lapho kucinywaIshubhu lesikwele esingu-16Mn:
(1)Ipayipi elide akufanele lifudunyezwe liqonde phezulu esithandweni sokugeza usawoti noma esithandweni somthombo ngangokunokwenzeka, ukuze kuncishiswe ukuguquguquka okubangelwa isisindo salo esiphelele.
(2)Uma kushiswa amapayipi anezingxenye ezahlukene esithandweni esifanayo, amapayipi amancane kufanele abekwe ekugcineni kwangaphandle kwesithando, futhi amapayipi amakhulu namapayipi amancane kufanele abekwe isikhathi ngokwehlukana.
(3)Inani ngalinye lokushaja kufanele lihambisane nezinga lamandla esithando. Uma inani lokuphakelwa likhulu, kulula ukulicindezela futhi izinga lokushisa liyakhuphuka, futhi isikhathi sokushisa sidinga ukwelulwa.
(4)Izinga lokushisa lokucima lamashubhu ayizikwele angunxande acinywe ngamanzi noma nge-brine kufanele lithathwe njengomkhawulo ophansi, kanti izinga lokushisa lokucima uwoyela noma usawoti oncibilikisiwe kufanele lithathwe njengomkhawulo ophezulu.
(5)Ngesikhathi sokucima okubili okuphakathi, isikhathi sokuhlala endaweni yokuqala yokucima kufanele silawulwe ngokwezindlela ezintathu ezingenhla. Isikhathi sokusuka endaweni yokuqala yokucima siye endaweni yesibili yokucima kufanele sibe sifushane ngangokunokwenzeka, okungcono kube yimizuzwana engu-0.5-2.
(6)Amapayipi angaphezulu kwawo angavunyelwe ukushiswa noma ukuhlanzwa kufanele afudunyezwe esithandweni sokugeza usawoti esilinganisiwe noma esithandweni somoya esivikelayo. Uma singahlangabezani nezimo, singafudunyezwa esithandweni sokumelana nomoya, kodwa kufanele kuthathwe izinyathelo zokuzivikela.
(7)Ngemva kokuba ithubhu elingunxande elingu-16Mn licwiliswe ngokuqondile endaweni yokucima uthuli, alishukumi, liya phezulu naphansi, futhi limisa ukuxubha kwendawo yokucima uthuli.
(8)Uma ikhono lokupholisa lezingxenye ezidinga ubulukhuni obukhulu linganele, yonke ingxenye ingacwiliswa endaweni yokucima ngesikhathi esifanayo, futhi izingxenye zingapholiswa ngokufafaza uketshezi ukuze kuthuthukiswe isivinini sokupholisa.
(9)Kumelwe ibekwe endaweni yokushisa ephumelelayo. Inani lokushaja, indlela yokushaja kanye nesimo sokufaka inqwaba kuzoqinisekisa ukuthi izinga lokushisa lokushisa liyafana, futhi akunakwenzeka ukubangela ukuguquka kanye nezinye izinkinga.
(10)Uma kushiswa esithandweni sikasawoti, akufanele kube seduze kakhulu ne-electrode ukuze kugwenywe ukushisa kakhulu kwendawo. Ibanga kufanele libe ngaphezu kuka-30mm. Ibanga ukusuka odongeni lwesithando kanye nokujula kokucwiliswa ngaphansi kwezinga loketshezi kufanele lilingane no-30mm.
(11)Insimbi yesakhiwo kanye nensimbi yekhabhoni kungashiswa ngqo esithandweni somlilo ngokushisa kokucima noma 20-30 ℃ okuphezulu kunezinga lokushisa lokucima. Insimbi yekhabhoni ephezulu kanye nensimbi ye-alloy ephezulu kufanele ishiswe ngokushesha cishe ku-600 ℃ bese iphakanyiswa ibe yizinga lokushisa lokucima.
(12)Izinga lokushisa lokucima lingakhushulwa ngokufanele kumapayipi anesendlalelo sokuqinisa esijulile, kanti izinga lokushisa eliphansi lokucima lingakhethwa kumapayipi anesendlalelo sokuqinisa esingajulile.
(13)Ubuso bepayipi lesikwele elingama-16Mn akumele bube namafutha, insipho nokunye ukungcola. Ngokuyisisekelo, izinga lokushisa lamanzi akumele lidlule ku-40 ℃.
