Yintoni i-ladle yokwakha i-ladle?

Izixhobo zokuphinda zenziwe i-ladle zizinto eziphambili ezisetyenziswa kwinkqubo yokuthambisa ukukhusela i-ladle ining kwaye inyanzelise ukukhukuliseka kweqondo lobushushu e-molten kunye ne-slag. Njengesona sitya siphambili sokubamba nokuhambisa i-molten yensimbi (ukusuka kwi-Conveter / izixhobo zombane zokuphoswa kwe-runish), izixhobo zokwenza izikhewu, zitshintsha kwaye zisabela ngendlela yobundlobongela. Oku kulandelayo ngamacandelo aphambili, iimfuno zomsebenzi kunye nemiceli mngeni yezobuchwephesha kwezixhobo ze-ladle:

Zithini izinto ze-ladle?

Izinto zokuphinda zenziwe i-ladle zibunjwe ikakhulu yi-Ladle Line kunye neeMveliso zokuSebenza zeLadle. Izinto zayo zokutshixa zangaphakathi kufuneka zikwazi ukumelana neemeko ezigqithileyo ezinjengokuphazamiseka, ukuphakanyiswa kwekhemikhali kunye nokutyibilika kwe-thermal yensimbi yeqondo lobushushu e-molten.

Iimfuno zomsebenzi we-ladle

• I-Slag Erosion: Indawo ye-Slag ye-Slag ifuna ukuxhathisa ukhukuliseko lwekhemikhali lwe-Straitity (Cao / Sio₂> 2).
• Ukunganyangeki kothuke ngenkani
• Amandla obushushu obuphezulu: Ukumelana noxinzelelo lwe-static yensimbi ye-molten (ezinjengoxinzelelo olusezantsi lwe-200 ye-Ton Ladle ifikelela ~ 0.3MPA) kunye nothuka.
• Ungcoliseko olusezantsi: Kulumkele ukungcola kwezinto eziphicothiweyo (ezinjengeSio₂) ekusebenzeni ngentsimbi enesibetho kunye nokuchaphazela ubunyulu bensimbi.

Indaleko kunye nemiceli mngeni yetekhnoloji yezinto ezibonakalayo

Ulungelelwaniso lwe-magnesia carbon izitena

Izitena zendabuko ze-magnesia ze-carbon: ixhomekeke kwigrafu yokuphucula ukunganyangeki kothusayo, kodwa igrafu i-axizelelo i-oxidonce (i-antioximages ifana ne-al kunye ne-SI kufuneka yongezwe).

I-carbon ye-carbonization ephantsi: Phuhlisa i-carbon ye-carbon ye-carbon (i-8%), yindawo efana ne-nanon ye-gitbon (efana ne-carbon ye-rabbon) ukunciphisa umngcipheko we-oxidation.

UKHUSELEKO LOKUFUNDA NOKUKHUSELEKO

Ingxaki yokungcola kweChromium: I-Magnesia yendabuko-chrome (MGO-CR₂O₃) ithintelwe ngenxa ye-carcinogenicity ye-carcinogenicity ye-carcinogenicity ye-CRCE.

Isisombululo esinye: Sebenzisa i-spinel (Mgal₂o₄) okanye i-magnesium-calcium (i-MGO-CAO) izixhobo, zombini zinokuhlala zinobuhlobo.

Izityalo ngokwakho

Iindlela eziqhelekileyo zokusilela kwezixhobo ze-ladle

I-Slag Erosion: I-Slag Peneration ibangela ukumiliselwa kwezigaba zendawo eziphantsi (njenge-cao-Mgo-Mgo-Sio₂) kumphezulu wezitena ze-magnen, kunye ne-Peels ecikizekileyo.

Uxinzelelo lwe-thermal wachitha: Utshintsho kubushushu obuqhelekileyo obubangela ukwanda kwee-microcracks ngaphakathi kwezinto, kwaye ekugqibeleni ukuchitha.

Ibhloko yezitena zomoya: I-insulings kwintsimbi ye-molten (njenge-al₂o₃) ifakwe kwimingxunya yomoya, echaphazela isiphumo se-Argon.

Ukusetyenziswa kwezixhobo ze-ladle:

Ukucoceka kwentsimbi yentsimbi: Sebenzisa iibhulukhwe eziphezulu zeCoundus (Al₂o₃> 99%) ukunciphisa ukungeniswa kokungcola.

Uyilo lobomi olude: I-proces ngokwenza ubume be-gradient (ezinje nge-masknesium ye-carbon kwindawo ye-Slag kunye ne-Aleuminium-Magnesis Readel Dall).

Ukubeka iliso elikrelekrele: Sebenzisa iingcinga ze-thermal ye-infrad okanye i-acoustic yokuphuma ngokubeka iliso kwimo yokukhukuliseka kwendawo yokutsala ngexesha lokwenyani.

Izixhobo zokuphinda zenziwe i-ladle zizinto ezinokuthengiswa kwenkqubo yenkqubo yokuthambisa, kwaye intsebenzo yazo ichaphazela umgangatho wensimbi ye-molten, ukhuseleko kunye neendleko. Xa kuthelekiswa nezixhobo zokuphinda zenziwe i-cundish, izixhobo ze-ladle kufuneka zinyamezele ixesha elide kwi-moltenses yensimbi yexesha, i-slag entsokothileyo yentsimbi kunye nemithwalo ephezulu yentsimbi. Izikhombisi zophuhliso lwexesha elizayo zibandakanya izixhobo zekharbhoni ephantsi kunye nendalo, uyilo lobomi obude kunye netekhnoloji yolondolozo. Umzekelo, ukusetyenziswa kwezixhobo ze-magnesium-caltives kunye neziphiko zekharbon ezingenakukuphucula nje kuphela ukuxhathisa i-SLAG kuphela kodwa ikwahambelane neemfuno zoveliso oluhlaza.
