Okokuqala, ukusetyenziswa kwe-agent ye-carburizing kwindlela yokutshisa i-furnace carburizing

1. Ikhabhoni, njengenye yezona zinto zibaluleke kakhulu kwintsimbi etyhidiweyo, kunzima ukuyilungisa kunezinye izinto.Ngenxa yokuba ikhabhoni ixinene kakhulu kunesinyithi solwelo, ukusebenza kakuhle kokufunxa kuya kuba sezantsi kakhulu ngaphandle kokuphazamiseka okunamandla.Ngokuqhelekileyo kwi-batching, ikhabhoni ngokomda ophezulu weemfuno zenkqubo, kwaye uqwalasele inkqubo yokunyibilikisa imbuyekezo yokutshiswa kwekhabhoni, ngoko linda de intlawulo yesinyithi icace, isixa sekhabhoni ngokusisiseko kuluhlu lwenkqubo, nokuba ngaphaya kancinci phezulu. umda ungasetyenziselwa ukongeza inani elincinci le-scrap (ecocekileyo, eyomileyo) kulula ukuyihlisa, kwiziko lombane lokunyibilikisa ikhabhoni kunokusebenza kwe-carburizing kulula kakhulu.

2. Ulandelelwano lokutyisa

Inyathelo 1: Okokuqala beka inani elithile lentlawulo yokubuyisela (okanye ushiye i-iron encinci yamanzi) phantsi kwesithando somlilo, ukwenzela ukuba izinto ezintsha zifakwe kwi-iron liquid, ukunciphisa i-oxidation.

Inyathelo lesi-2: Yongeza intsimbi yentsimbi kuqala, emva koko wongeze i-agent ye-carburizing.Ngeli xesha, i-melting point ye-liquid iron iphantsi, inokunyibilika ngokukhawuleza ukuphucula ukuphakama kwinqanaba le-liquid, ukwenzela ukuba i-agent carburizing ingene kwi-iron liquid.Ungqamaniso lwe-carburizing kunye nokunyibilika kwentsimbi akunyusi ixesha lokunyibilika kwaye kudla amandla amancinci.Ngenxa yokuba umthamo wokunciphisa we-FeO ngu-C uphezulu kune-Si kunye ne-Mn, ilahleko evuthayo ye-Si kunye ne-Mn inokuncitshiswa ngokudibanisa i-carburizer kwiqondo lokushisa eliphantsi.Zama ukusebenzisa iingxowa zokupakisha ezipakishwe nge-agent ye-carburizing kwiziko lombane, musa ukusebenzisa i-pinch ye-spade kwiziko lombane, ukuze uthintele amasuntswana amahle ukuba afunxelwe ngumqokeleli wothuli.

Inyathelo lesi-3: I-scrap iyanyibilika kwaye intlawulo yokubuyisela yongezwa.Ukuqinisekisa ukuba i-agent ye-carburizing ifakwe ngokupheleleyo phambi kwe-slagging, ngeli xesha, isithando sombane esinamandla amakhulu (> 600kW / t) sibaluleke kakhulu kuba ixesha elifunekayo lokunyibilikisa impahla linokuba ngaphantsi kwexesha elifunekayo lokufunxa ngokupheleleyo. i-carburizer.Ngelo xesha, umsebenzi oshukumisayo wesithando sombane kufuneka usetyenziswe kwinqanaba eliphezulu kwinkqubo yokuxutywa kwe-agent ye-carburizing.

Inyathelo lesi-4: Ukuba izinga lokubuyisela i-agent ye-carburizing kunye nokulawulwa kwekhabhoni ye-iron ye-liquid iqinisekile, i-agent ye-carburizing inokongezwa kunye ne-scrap kanye.Ukongezwa okwesibini kwe-carburizing agent yi-fine-tuning carbon (okanye isongezelelo sekhabhoni etshisiweyo), kufuneka yongezwe emva kwe-iron liquefier, ngaphambi kokujoyina i-slag yolwelo lwentsimbi, kangangoko kunokwenzeka ukunqanda i-arhente ye-carburizing ebandakanyeka kwi-slag, emva koko. amandla aphezulu ombane usebenzisa isithando sombane esivuselela umsebenzi wokuphucula izinga lokufunxa.

Inyathelo lesi-5: Yongeza i-ferrosilicon kunye nezinye i-alloys, uhlalutyo lwesampulu, lungisa ukubunjwa, ngaphandle kwe-oven.Kuphephe ukugcina i-iron elulwelo kwiqondo lobushushu eliphezulu ixesha elide.Ukugcinwa kwexesha elide le-iron elulwelo kubushushu obuphezulu (ingakumbi ukugqunywa kwexesha elide ngaphezulu kwe-1450 ℃) kulula ukukhokelela kwi-oxidation ye-carbon, ukwanda komxholo we-silicon (i-silicon dioxide iyancitshiswa) kunye nokulahleka kwe-crystal nuclei kwintsimbi engamanzi. .

Okwesibini, ukusetyenziswa kwe-arhente ye-carburizing kwindlela yokubeka iphakheji

Ukuba kuyimfuneko ukungcwatywa kwipakethe, ubungakanani besuntswana le-100 ~ 300 yenjongo yokungcwaba inokubekwa emazantsi epakethe, kwaye intsimbi yolwelo olushushu oluphezulu igutyungelwa ngokuthe ngqo kwi-arhente ye-carburizing (okanye yongezwe ngentsimbi engamanzi. ukuhamba), kwaye intsimbi ishukunyiswa ngokupheleleyo emva kokuchithwa kunye nokufunxa kwekhabhoni.Impembelelo ye-carburizing kwi-package ayilungile njengaleyo kwisithando somlilo, kwaye izinga lokufunxa kunzima ukulawula.Nokuba isetyenziswa njani iarhente ye-carburizing okanye indlela ye-carburizing kufuneka imiselwe ngenkqubo yovavanyo lwemveliso ye-carburizing kunye nenqanaba lokufunxa xa sele imisiwe, musa ukuthatha indawo ngokulula uhlobo lwearhente ye-carburizing kunye nemvelaphi, ukuba ufuna ukuyitshintsha kufuneka iphumelele isiqinisekiso semveliso. kwakhona.
