Dziko lapansi litha kusintha bwino kulimba kwazitsulo

Monga tonse tikudziwa, kuwonjezera kuchuluka kwa zinthu zapadziko lapansi pazinthu zachitsulo kumakhudza kapangidwe kake ndi magwiridwe antchito. Nthawi zambiri zinthu zosowa zapadziko lapansi zachitsulo zimawonjezedwa mu 0.05% ~ 0.20%. Chifukwa kuchuluka kwa ma atomiki a nthaka yosawerengeka ndi chitsulo kumapitilira 15%, ndipo kusiyana kwamagetsi pakati pa nthaka ndi chitsulo ndikwakukulu kwambiri, izi sizothandiza pakupanga yankho lolimba, chifukwa chake kusungunuka kwa nthaka yosowa mu chitsulo ndi otsika kwambiri. Zambiri mwazinthu zosowa zapadziko lapansi zachitsulo zimakhalapo ngati zinthu zosowa zapadziko lapansi, makamaka ma oxide apadziko lapansi osowa komanso ma sulfide apadziko lapansi.

Xi'an Aeronautical Vocational and technical College yapanga kafukufuku wokhudza kuwonjezera zinthu zapadziko lapansi zosapanga chitsulo pamapangidwe ake ndi momwe amagwirira ntchito. Anagwiritsa ntchito ZG35CrMnSi ngati chitsulo choyeserera, ndipo chowonjezera chosowa cha dziko lapansi chomwe chidagwiritsidwa ntchito chinali chosakanikirana ndi dziko lapansi. Poganizira kuti zinthu zoyeserazo zili ndi sulufule wambiri Ndipo kutayika pakuwonjezera zinthu zosowa zapadziko lapansi, kuchuluka kwowonjezera kwapadziko lapansi ndi 0.23% ~ 0.38%, kuwonjezera kumeneku kumatanthawuza kuchuluka kwa nthaka yosawerengeka yomwe idawonjezeredwa pazitsulo zosungunuka pakasungunuka. Yerekezerani kapangidwe kake ndi magwiridwe antchito amitundu iwiri yopanda zinthu zapadziko lapansi. Kuponyera kwazitsulo kumasungunuka mu ng'anjo yapakatikati, ndipo kuponyako kumakonzedwa ndikuponya ndalama. Kenako chidutswa choyeserera chimatenthedwa mpaka 900 ° C + 670 ° C pakuzizira kwa mpweya, kenako ndikuwotcha mpaka 890 ° C pakutha mafuta; ndiye 570 ~ 630 ° C moto.

Zotsatira zofananira zikuwonetsa kuti dziko lapansi lomwe silikupezeka silimakhudza kwenikweni chitsulo chosanjikiza, koma limakhudza kulimba kwa chitsulo chosungunuka. Kulimba mtima kukuwonjezeka ndi 43%, ndipo kukwezedwa kwake kukuwonjezeka ndi 13.3%. Kuyang'anitsitsa kwa Microstructure kumawonetsa kuti sorbite yoyeserera ya chitsulo chosapanga popanda zinthu zapadziko lapansi ndizocheperako, ndipo kukula kwake kwa tirigu pafupifupi 5; Mwa zina, zotuwa zotuwa ndi MnS inclusions, zomwe sizigawidwa pamalo onse oyang'aniridwa. Mwambiri, morphology ya MnS imakhala yaying'ono. Zitsanzo zazitsulo zopangidwa ndi zinthu zosowa padziko lapansi ndizofanana ndi sorbite wofatsa, ndipo kukula kwa tirigu ndi pafupifupi 8-9. Zikuwonetsa kuti kapangidwe kazitsulo kazitsulo kangakonzedwe pambuyo powonjezera zinthu zosowa zapadziko lapansi.

Kuphatikiza apo, atawonjezera zinthu zosowa zapadziko lapansi, kuwonongeka kwa chitsulo sikuwonekera, koma kumakhudza kwambiri kafukufuku wa MnS. Zinthu zapadziko lapansi zikapanda kuwonjezeredwa, MnS muzitsulo imakhala ngati mizere kapena zotchinga m'mbali ndi ngodya; Pambuyo powonjezera zinthu zosowa zapadziko lapansi, sulfide ili pafupifupi mozungulira, ndipo magawidwewo amabalalika molingana ndi nyembazo popanda zinthu zapadziko lapansi, koma m'malo ochepa Mutha kuwona kuvula kapena kutseka ma incluside inclusions. Pakaphulika kazitsanzo popanda zinthu zosowa zapadziko lapansi, MnS imakhazikika komanso imakhala yolimba. Kuphulika kwa malo ophatikizira a MnS makamaka ndikuphwanyika kwamkati, ndipo ming'alu yaying'ono yapakatikati imatha kuwoneka kwanuko.

Mu zitsanzo zomwe zimakhala ndi zinthu zapadziko lapansi zosweka, kuphulika ndi kuphulika kwa ductile transgranular. Ngakhale mdera lomwe ma sulfide amakhala opindika, chitsulo chosanjikiza chimaphulikabe ductile transgranular. Chitsulo chosungunuka chowonjezeredwa ndi zinthu zapadziko lapansi chimachotsa ma dendritic sulfide ndikuwasintha kukhala ndodo zozungulira kapena zopanda mawonekedwe komanso ma sulfide apadziko lapansi osowa, omwe ndi othandiza pakulimba kwa kulimba.

Kafukufuku akuwonetsa kuti mfundo yoti kukonzanso kwapadziko lapansi kosayenerera mwina chifukwa cha zifukwa izi:

(1) Sulfide ndi ma oxide inclusions opangidwa powonjezera zinthu zosowa zapadziko lapansi pazitsulo zimatha kukhala zosapanga zokha zachitsulo, zomwe zimatha kuyenga makhiristo ofananirako ndikufupikitsa zigawo za crystal.

(2) Kusungunuka kwa zinthu zapadziko lapansi zomwe zili mgulu laling'ono ndizochepa kwambiri. Chitsulo chosungunuka chikakhazikika, maiko osowa amakulitsilidwa mu gawo lamadzi kutsogolo kwa makhiristo omwe akukula, kuletsa makhiristo kukula, ndikupangitsa njere kuyengedwa.

(3) Zinthu zapadziko lapansi zimakonda kuchuluka m'malire, zimachepetsa kulumikizana kwa aloyi, komanso zimachepetsa mphamvu zoyambira, zomwe zimalepheretsa kukula kwa mbewu za austenite. Momwemonso, flaky martensite yopangidwa ndi kuzimitsa ndiyonso yaying'ono. .

Chonde sungani komwe adachokera ndi adilesi iyi kuti musindikizenso: Dziko lapansi litha kusintha bwino kulimba kwazitsulo
