Ukuphosa inkqubo yemveliso ye-ductile yentsimbi 500-7

Ngokusekwe kwiimpawu zokwenza izinto ezizezomgangatho, izinto ezilinganayo zeziphoso zikhethiwe, kwaye i-Ladle ekhethekileyo yentsimbi isetyenziselwa ukomeleza inkqubo ye-spheroids kunye nemveliso ye-gured ye-qt500-7 ineemfuno zentsimbi ezihlanganisiweyo. Ukuveliswa kwentsimbi ephezulu yentsimbi inokufezekiswa ngamanyathelo anjengokusabela ukomeleza ubume bematrix. Nangona kunjalo, ukuveliswa kwe-Qt500-7 intsimbi ye-ductile ngokusebenza kakuhle kunzima kakhulu kunzima ukuba ubukho bezinto ezininzi ze-pigs, kunye ne-alloys eqinisayo ekwenzeni intsebenzo yentsimbi. Nantsi isishwankathelo seminyaka yethu yenkampani yokuvelisa imveliso ye-1-10kg) kunye neenxalenye zentsimbi ezixineneyo

Iimfuneko zeNtsebenzo kunye neMenti ye-Meeni ye-Meenellographic: amandla e-thensle ≥ 500n / mm

Isiveliso Ngokweempawu zesakhiwo, ubukhulu, kunye neemfuno zokuphononongwa, ukukhetha ikhemikhali ngolu hlobo lulandelayo :.6%, <0.03% I-ressane, i-0.035% ukuya kwi-0.6% MG, kunye nentsalela / intsalela yentsalela / i-MG maqinisekiswe ukuba iqinisekiswe ukuba ibe ≤ 2/3.

Ishishini apho umbhali esebenza isebenzisa i-0.5T Prequium yeTransquencyTencyTency yeTransquencyT yokunyibilikisa i-Iron enyibilikisi, eneqondo lokushisa ngaphezulu kwe-1520 ℃. Ukwamkela i-0.5t Ductile yentsimbi ye-purle pirle pirching punch yokuphononongwa konyango lwe-spresidization. Iarhente ye-spreroding yi-Feesm8re5 nge-GB4138-88, kwaye i-Inoculant yi-Silicon Bagium ye-InOculant inoculam. Emva kokuphumelela uhlolo lwethanga lokuhlala, lungathunyelwa ngokukhawuleza. Lawula ixesha lokuphalalela ngaphakathi kwemizuzu eli-15 ukuthintela ukupheliswa nokuwohloka.

3.1 Isixa sentsimbi etyhutyha i-iron ephathwayo kunye nearhente ye-spreroding yi-0.5 yeetoni, kunye nobungakanani be-arhelicle yearhente ye-spreroding kufuneka ibe yi-10-20mm. Iqhezu le-Stherodiding ye-Arheroding Agements incinci kune-10mm akufuneki idlule kwi-10%. Iarhente yokuqhubela phambili kufuneka yomiswe kwaye iphindwe kabini, ngokukhethekileyo nge-150-200 ℃. Ukuba iimeko zivuma, i-hopper ekhethekileyo inokwenziwa ngokubhaka kumlomo wesithando somlomo. Sinethemba lokuvelisa i-ductile intsimbi eneqondo lokushisa eliphezulu le-iron, umxholo wegesi ophantsi, akukho zungu, kunye nokwenziwa kwezinto ezithile. Kule mihla, iintlobo ngeentlobo zeflast Ngenxa yeempawu ezizodwa zohlobo lwesithando somxholo Inkampani yethu isebenzisa iziko eliphakathi, elinobuhlobo lwendalo. Iqondo lobushushu le-iron elityhidiweyo kulula ukulawula, ukubekwa kweekhemikhali kuyazinza, kwaye akukho ngcaciso kangaka.

3.2 Ukuthulula i-Ladle

3.2.1 Iimfuno zobukhulu: Sebenzisa i-Suctile ye-Halting yentsimbi. Umlinganiso wokuphakama ububanzi obuya kububanzi bemidlalo eqhelekileyo yi-1.1-12, kunye nomlinganiselo wokuphakama ukuya kububanzi be-gucile yentsimbi yi-1.5 (i-diameter ibhekisa kububanzi bomlomo womlomo). Indawo engaphakathi kwi-akhawunti ye-PIT yama-50% ukuya kwi-60% yendawo esezantsi yeledle, kwaye ubunzulu bungayifumana iarhente eyongeziweyo, inoculant, kunye nearhente egubungele iarhente. Ububanzi bomlomo we-duccile intsimbi buncinci kunokuba ububanzi bomlomo we-ladle jikelele wemilomo efanayo. Ukuqwalaselwa koyilo lweLadle:

I-a, ukuphakama kwephakheji kuqinisekisa ukuphakama okwaneleyo ngaphezulu kwearhente yokufihla, ukwandisa uxinzelelo lwekholam ye-molten. I-spheroding arhente idada ixesha elide, elungele ukufunxa i-iron etyhidiweyo. Kwangelo xesha, amaqabu e-magnesium adada kwaye athathe ixesha elide ukubaleka kumphezulu wensimbi etyhidiweyo;

B, ukuba ububanzi bephakheji buncinci, inani lamaqhina e-magnesium abalekayo kwangaxeshanye, incipha incipha, kwaye ilahleko ye-Oxidation incinci, kwaye ilahleko yobushushu iyacotha. Ubungakanani kunye nolwakhiwo lwe-thungle

3.2.2 Iimfuneko zokumisa isidanga: I-LADLE kufuneka yomiswe ngokupheleleyo ngaphambi kokusetyenziswa.

3.3 Iindlela zokuSebenza

3.3.1 Ukuzelwa kweledle: I-LADLE esetyenzisiweyo okokuqala kufuneka ibhakwe ngokupheleleyo ngomthi ocothiweyo. Xa isetyenziswa kwakhona, inokubhakwa ngomthi otshisiweyo okanye i-itrong ngentsimbi etyhidiweyo.

3.3.2 isixa searhente yokuqhubela phambili yongezwa yi-1.0% ukuya kwi-1.2%, inani le-inoculant yongezwa yi-0.8% ukuya kwi-1,0%, kunye nenani le-Arhente yokugubungela i-0.5% ukuya kwi-1.0%

3.3.3 Indlela yokulayisha: Okokuqala, beka iarhente yokufihlakala kumngxunya we-concave emazantsi ephakheji kwaye icombolole. Emva koko, yigubungele nge-inoculant kwaye uyicombulule kwakhona. Okokugqibela, yongeza i-arhente yokugubungela kunye nentsimbi yentsimbi ngokulandelelana kwaye iqulathe ipleyiti yentsimbi (ukuba imvume ye-Imple yentsimbi, icocekile kwaye i-oyile yentsimbi yentsimbi).

3.3.4 INKQUBO YOPHANDO YOKUGQIBELA: Thula i-ping encwina kwi-ladle ukusuka kwisithando somlilo kwi-iron etyhidiweyo iwele kwi-iron yentsimbi ye-Iron kunye nokuphendula i-sprerodiving kunye nesabelo kunye ne-arhente ye-sprerodiving. Kungcono ukulawula i-iron etyhidiweyo ukuqala i-spreroding fitting xa igqitha i-300mm yearhente ye-sprerodiving. Emva kokuba i-Iron etyhidiweyo ikhutshiwe, khawuleza igubungele indawo yokuphaphama kwe-spresidiation ngekhava yentsimbi. Emva kokuphendula sizinzile, thatha ikhava yentsimbi ukususa i-slag kunye nokutshiza iarhente yokugubungela.

Isishwankathelo semiphumo yemveliso

4.1 Ukuqulunqwa kweziphoso kunye nokusebenza kweesampunzi:

4.2 Isampulu ye-Tomatite kunye neMatrix Feellographic Procus 5 Umgangatho weNkqubo yokuSebenza ishwankathela iminyaka ye-qt500-7 ye-qt500-7, i-qg500-7, kubaluleke kakhulu ukulawula umxholo we-Pearlix kwisakhiwo se-pirus I-spiroidssetion. Umbhali ukholelwa ukuba la manqaku alandelayo yeyona nto ibaluleke kakhulu kwimveliso yezinzile yeQt500-7 intsimbi ye-ductile:

5.1 Isinyithi siphuma kubushushu besithando somlilo: Ukuba i-iron iphume kakhulu kubushushu bemililo iphezulu kakhulu, iya kubangela ukuba ixesha lokuqalisa liqaqambe, oko kukuthi, iron ulwelo liza kuqala ukuphakama ngaphambi kokufikelela kwinqanaba elaneleyo. Kwangelo xesha, ulwelo lwentsimbi luya kugcuma ngogonyamelo, lubangela ukutsha kwe-MG kunye nokuhla kwenqanaba lokufumana. Ngapha koko, ukukhula kunye nokubola kuya kukhawuleza, kukhokelela ekuphuculeni okungalunganga okanye ukubola; Ukuba iqondo lobushushu le-iron elenziwe liphantsi kakhulu, linokubangela ukucocwa okanye ukuqhubela phambili kunye nokuqaliswa kwentsimbi etyhidiweyo. Iqondo lobushushu le-0.5t ladle lincipha malunga ne-80-100 yenkqubo yokuphendula ye-spheroid, ke iqondo lobushushu lonyango lwentsimbi emva kokuba ikhutshwe kwiziko kufuneka libe yi-100-120 ℃ iphezulu kuneqondo lokuphumla. Ke ngoko, iqondo lobushushu lonyango lwentsimbi emva kokuba ukhutshiwe kwiziko kufuneka lilawulwe phakathi kwe-1500-1520 ℃

5.2 Lawula umxholo wekhabhoni kunye nomxholo we-silicon kwintsimbi enyibilikisiweyo, ngokungqongqo emva komgaqo "wekhabhoni ephezulu kunye nesilicon ephantsi".

5.3 Umxholo wentsalela yentsalela kunye nentsalela ye-MG kufuneka ilawulwe ngokungqongqo, kwaye umyinge wentsalela kwintsalela ye-MG kufuneka iqinisekiswe ukuba ibe ≤ 2/3. 5.4 Sebenzisa izixhobo ezikumgangatho ophezulu, uzinze imithombo yezinto ezibonakalayo, kwaye ulawule ngokungqongqo umxholo wesalfure kunye nokulandelela izinto eziyingozi. Ukuza kuthi ga ngoku, kuyimfuneko ukomeleza ukuphathwa kwezinto zethanga, ekufuneka kudweliswe kwaye kubekwe uphawu olucacileyo, kunye nobunzima obuchanekileyo xa bongeza izixhobo.

5.4.1 I-pig iron: Kungcono ukukhetha intsimbi equkethe ingaphantsi kwe-2% isilicon kunye ne-0.1% phosphorus. I-tonnage yayo ayiyi kuba ngaphantsi kwe-50 yeetoni ukugcina ixesha elizinzileyo le-duccile yentsimbi.

5.4.2 Izixhobo ezisetyenzisiweyo: I-Scrap Dactile kunye ne-Scraes yelibakala kufuneka zisuswe kwisanti kunye nee-oxiles, zihlelwe kwaye zibhalwe, kwaye zibizwa ngokuba zibunjwe ngamachiza.

5.4.3 Intsimbi ye-Scrap: I-Screbon ekumgangatho ophezulu Scbon Scrap kufuneka isetyenziswe kangangoko kunokwenzeka. Kwangelo xesha, abo banomongo onzulu kunye nobunzima obungaphantsi kwe-2mm akufuneki ukuba basetyenziswe njengezixhobo ze-iron yentsimbi ukunciphisa ii-oxiles kwaye ziququzelele ukukhutshwa kwesandiso. Ubungakanani bebhlokhi yezixhobo zokugcina ngasentla kufuneka bube ngaphantsi kwe-1/3 yemithanga yangaphakathi yokuthintela ifuthe lezinto ezichithwayo kwiqondo le-iron elinentsimbi.

5.5 Iiarhente zokuchitha kufuneka zitywinwe kwaye zigcinwe ukuthintela i-oxidation kunye nokufuma.
