Iziko lokubumba elifudumeleyo iiparamitha kunye neempawu

Iiparamitha ezishushu zokubumba eziko:

1. Izinto zebhilidi: 20CrMnTi 20CrMoH SAE4320H 17CrNiMoH.

2. Uluhlu lwenkcazo engenanto: ububanzi φ32-50mm; ubude 70-102mm.

3. Ukufudumala kweqondo lokushisa: ukufudumala kwi-100-200 ℃, ukufudumeza kwi-850-950 ℃.

4. Ukubetha: φ42, ubude be-102mm, imizuzwana emi-4 / isiqwenga.

5. Ukufudumala kuzinzile ngexesha lokusebenza okuqhelekileyo, kunye nokufudumala kweqondo lokushisa phakathi kwecandelo ngalinye lezinto eziphathekayo ngaphakathi kwe-± 15 °C; umehluko weqondo lokushisa kwi-billet emva kokufudumeza: i-axial (intloko kunye nomsila) ≤ ± 50 °C; i-radial (itafile engundoqo) ≤ ±50 °C.

6. Uxinzelelo lwenkqubo yokubonelela ngamanzi okupholisa lukhulu kune-0.5MPa (uxinzelelo lwamanzi oluqhelekileyo lungaphezu kwe-0.4MPa), kwaye ubushushu buphezulu njenge-60 ° C. Uxinzelelo lombhobho ohambelanayo kunye nojongano nazo kufuneka zonyuswe ngokulinganayo kumgangatho wokhuseleko

Iimpawu zesithando somlilo esifudumeleyo:

1. Isantya sokufudumeza sikhawuleza kwaye ukusebenza kwemveliso kuphezulu. Iyakwazi ukuqonda ukuveliswa ngokuzenzekelayo kwezinto zebar ngokuthe ngqo emva kokufudumeza kunye nokugubungela. Amandla afunekayo okugquma amancinane. Umgama ohambisayo phakathi kweenkqubo ezintathu zokufudumeza, ukugquma kunye nokukhwabanisa ufinyeziwe, ukwenzela ukuba intsimbi ibethwe ngelixa i-iron ishushu. Ihambelana nomatshini wokubumba kunye neqondo eliphezulu lokuzenzekelayo kunye nokusebenza okuphezulu ukuqonda ukuzenzekelayo komgca wemveliso yokubumba kunye nokunika umdlalo ogcweleyo kumandla okuvelisa umatshini wokubumba.

2. Ukutshintshwa kwe-furnace body induction kulula. Iziko lokufudumeza elifudumeleyo lokufudumeza libandakanya ubukhulu becala unikezelo lwamandla ombane ophakathi kunye nomzimba wesithando somlilo, esisisakhiwo esahlukileyo. Kwiminyaka emininzi yamava asebenzayo ekwenziweni kweziko lombane laseHaishan, ngokweemfuno ezahlukeneyo zabasebenzisi, siyila kwaye senza iseti epheleleyo yezixhobo zokufudumeza nge-intermediate ezimbini eziphakathi, iseti enye yobonelelo lwamandla kunye neeseti ezimbini zombane. imizimba yeziko. Ngokutsho kobukhulu obuhlukeneyo bokucutshungulwa, imizimba ye-furnace ye-induction yenkcazo eyahlukeneyo icwangcisiwe. Tshintsha ukufudumeza okanye ukufudumeza ngaxeshanye. Umzimba ngamnye wesithando somlilo wenzelwe ngamanzi, umbane kunye nokudibanisa ngokukhawuleza, okwenza ukutshintshwa komzimba wesithando somlilo kube lula, ngokukhawuleza kwaye kulula, akugcini nje ukugcina umbane wamandla, kodwa kunciphisa ixesha lokutshintsha umzimba wesithando somlilo.

3. Ukusetyenziswa kwamandla aphantsi, akukho ngcoliseko, i-furging forging furnace yeyona ndlela yokufudumeza eyonga amandla phakathi kweziko lokufudumeza kombane; Amandla okusetyenziswa kwetoni nganye yokufudumeza ukusuka kubushushu begumbi ukuya kwi-1100 ℃ ingaphantsi kwe-360 ℃. Ukufudumeza amaza aphakathi aphakathi kunokonga amandla ngama-31.5% ukuya kuma-54.3% kubushushu obukhethekileyo be-oyile yomxhuzulane, kunye ne-5% ukuya kuma-40% ekongeni amandla kunokufudumala kwegesi. Xa kuthelekiswa nesithando somlilo samalahle, isithando somlilo esiphakathi asivelisi ungcoliseko xa isithando somlilo esiphakathi sisetyenziswa kwimveliso yokwenziwa, kwaye ukusebenza kakuhle kwe-thermal yesithando somlilo kuphezulu xa kuthelekiswa nesithando somlilo esiqhelekileyo;

4. Gcina izinto eziphathekayo kunye neendleko, ukwandisa ubomi bokubumba, ukwandisa imveliso nge-10% ukuya kwi-30%, kwaye wandise ubomi besikhunta nge-10% ukuya kwi-15%.

5. Ukuchaneka kokulawula ukushisa kuphezulu kwaye ukufudumeza kufana. Isithando somlilo esifudumele sithatha ukuchaneka kokulawula ubushushu ukulawula ngokuchanekileyo ubushushu, okuqinisekisa izinga elifanelekileyo leemveliso kunye nokunciphisa izinga lokwaliwa nge-1.5%. Ukufudumala kwe-induction kulula ukufezekisa ukufudumeza okufanayo, kwaye umehluko weqondo lokushisa phakathi kwengundoqo kunye nomphezulu omncinci.
