Chitsulo chokhala ndi chitsulo chimagwiritsidwa ntchito makamaka popanga zinthu zogubuduza ndi mphete za mayendedwe oyenda.Chifukwa kubereka kuyenera kukhala ndi moyo wautali, mwatsatanetsatane, kutentha kochepa, kuthamanga kwambiri, kukhazikika kwakukulu, phokoso lochepa, kukana kuvala kwambiri, etc., chitsulo chonyamula chiyenera kukhala ndi: kuuma kwakukulu, kuuma yunifolomu, malire othamanga kwambiri, kutopa kwakukulu, kutopa kwambiri. Mphamvu, kulimba kofunikira, kuuma kwina, kukana kwa dzimbiri mumafuta mumlengalenga.Pofuna kukwaniritsa zofunikira zomwe zili pamwambazi, zofunikira kuti zikhale zofanana ndi zomwe zimapangidwa ndi zitsulo zokhala ndi zitsulo, zomwe zili ndi mtundu wazitsulo zopanda zitsulo, kukula ndi kugawa kwa carbides, ndi decarburization ndizovuta.Kukhala ndi zitsulo nthawi zambiri kukukula kwambiri, kuchita bwino kwambiri komanso mitundu ingapo.Chitsulo chokhala ndi chitsulo chimagawidwa kukhala chitsulo cha carbon chromium chokhala ndi zitsulo, zitsulo zokhala ndi carburizing, zitsulo zotentha kwambiri, zitsulo zosapanga dzimbiri ndi zipangizo zapadera zotengera malinga ndi makhalidwe ndi chilengedwe.Pofuna kukwaniritsa zofunikira za kutentha kwakukulu, kuthamanga kwambiri, kulemedwa kwakukulu, kukana kwa dzimbiri ndi kukana kwa ma radiation, mndandanda wazitsulo zatsopano zokhala ndi katundu wapadera ziyenera kupangidwa.Pofuna kuchepetsa mpweya wa zitsulo zokhala ndi zitsulo, njira zamakono zosungunulira zonyamula zitsulo monga vacuum smelting, electroslag remelting, ndi electron remelting remelting zapangidwa.Kusungunula kwazitsulo zazikulu zokhala ndi zitsulo zapangidwa kuchokera ku ng'anjo yamagetsi yamagetsi yamagetsi kupita ku mitundu yosiyanasiyana ya ng'anjo zoyamba zosungunula ndi kuyeretsa kunja kwa ng'anjo.Pakali pano, kubala zitsulo ndi mphamvu ya matani oposa 60 + LF / VD kapena RH + mosalekeza kuponyera + mosalekeza Kugudubuza njira ntchito kutulutsa kubala zitsulo kuti akwaniritse cholinga chapamwamba, dzuwa mkulu ndi otsika mphamvu.Pankhani ya kutentha kutentha, ng'anjo pansi galimoto ndi ng'anjo hood zapangidwa mosalekeza kulamulidwa mpweya annealing ng'anjo kutentha kutentha.Pakalipano, mtundu wa ng'anjo yotentha yosalekeza uli ndi kutalika kwa 150m, ndipo mawonekedwe a nodular a zitsulo zokhala ndi zitsulo ndizokhazikika komanso zofananira, wosanjikiza wa decarburization ndi wochepa, ndipo kugwiritsa ntchito mphamvu kumakhala kochepa.
Zovala zachitsulo ziyenera kukhala ndi zinthu zotsatirazi:
1. High kukhudzana kutopa mphamvu.
2. High abrasion kukana.
3. High zotanuka malire ndi zokolola mphamvu.
4. Kuuma kwakukulu ndi yunifolomu.
5, kulimba kwina kwina.
6. Good dimensional bata.
7, ntchito yabwino yoletsa dzimbiri.
8. Good ndondomeko ntchito.
Kukhala ndi zitsulo wamba:
Kusankhidwa kwa zitsulo zonyamula katundu kumafunanso kugula kwapadera.Pazinthu zonyamula zomwe zimagwira ntchito mwapadera, malinga ndi zofunikira zawo, ziyeneranso kukhala ndi zinthu zapadera zomwe zimagwirizana ndi momwe zinthu zilili, monga: kukana kutentha kwambiri, kutsika kwa kutentha, kukana kwa dzimbiri, Anti-radiation, anti-magnetic and makhalidwe ena.
Chitsulo cholimba cholimba kwambiri chimakhala chitsulo chokwera kwambiri cha carbon chromium, monga GCr15, chomwe chili ndi mpweya pafupifupi 1% ndi chromium pafupifupi 1.5%.Pofuna kukonza kuuma, kukana kuvala ndi kuuma, silicon, manganese, molybdenum, ndi zina zotero, monga GCr15SiMn, zimawonjezedwa moyenera.Chitsulo chamtunduwu chimakhala ndi chitsulo chachikulu kwambiri, chomwe chimawerengera zoposa 95% yazinthu zonse zokhala ndi zitsulo.
Carburizing yokhala ndi chitsulo ndi chromium, faifi tambala, molybdenum alloy structural chitsulo chokhala ndi mpweya wa 0.08 mpaka 0.23%.Pamwamba pa gawo lonyamula ndi carbonitrided kuti apititse patsogolo kuuma kwake ndi kuvala kukana.Chitsulochi chimagwiritsidwa ntchito popanga mayendedwe Akuluakulu omwe amanyamula katundu wamphamvu, monga mayendedwe akuluakulu a mphero, mayendedwe agalimoto, makina opangira migodi, ndi mayendedwe agalimoto yanjanji.
Zitsulo zosapanga dzimbiri zimakhala ndi zitsulo zosapanga dzimbiri za carbon chromium, monga 9Cr18, 9Cr18MoV, ndi zitsulo zosapanga dzimbiri za carbon chromium, monga 4Cr13, ndi zina zotero, zomwe zimagwiritsidwa ntchito kupanga zitsulo zosapanga dzimbiri komanso zosapanga dzimbiri.
Kutentha kwakukulu kwachitsulo kumagwiritsidwa ntchito pa kutentha kwakukulu (300 ~ 500 ℃).Zimafunika kuti chitsulocho chikhale ndi kuuma kwina kofiira ndi kuvala kukana pa kutentha kwa ntchito.Ambiri aiwo amagwiritsa ntchito zida zachitsulo zothamanga kwambiri, monga W18Cr4V, W9Cr4V, W6Mo5Cr4V2, Cr14Mo4 ndi Cr4Mo4V.
