Ntchito yozizira imafa kwambiri imagwiritsidwa ntchito polumikizidwa, ndikupanga, kugwedezeka, zofunda, zojambula zozizira, kuvala ufa kukana komanso kulimba mtima. Nthawi zambiri amagawika m'magulu awiri: Mtundu wa General ndi Mtundu wapadera. Mwachitsanzo, cholinga chachikulu chozizira chimafa zitsulo ku United States nthawi zambiri zimaphatikizapo magiredi anayi achitsulo: 01, A2, D2, ndi D3. Kuyerekezera kwa magawano achitsulo omwe amagwira ntchito kwa Alloy Dieel m'maiko osiyanasiyana akuwonetsedwa pazida 4. GB / T1299EL chida chachitsulo chimaphatikizapo mitundu 11 yachitsulo, ndikupanga mndandanda wokwanira. Ndi kusintha kwa ukadaulo wosinthira, zida zopangidwa ndi kufunikira kwa nkhungu, mndandanda woyambirira sangakwaniritse zosowa. Mphero yachitsulo ya ku Japan ndi chida chachikulu cha ku Europe ndi kufa opanga zitsulo zayamba ntchito yapadera kufa zitsulo, ndipo kukula kwa ntchito yozizira kumafanso ndi chitsogozo cha ntchito yozizira.
Alloy Air Runch Steench Steenet Ife Chitsulo
Ndi chitukuko cha ukadaulo wamateni, makamaka kugwiritsa ntchito ukadaulo wokhwima mu bizinesi yama nkhunge, kuti achepetse zitsulo zotsika kwambiri, zodetsa zowonongeka zamitundu yotsika kwambiri zamiyala zidapangidwa kunyumba ndi kunja. Zitsulo zamtunduwu zimafuna kuuma kwabwino komanso chithandizo chamatenthedwe zimakhala ndi kutsamba pang'ono, mphamvu zabwino komanso kulimba, ndipo zimasokoneza ena. Ngakhale ozizira kwambiri-alloy ntchito amafa zitsulo (monga D2, A2) ali ndi vuto labwino, lili ndi chilono chachikulu ndipo ndiokwera mtengo. Chifukwa chake, zitsulo zina zowonongeka pang'ono zachibeke za kirow zimapangidwa kunyumba ndi kunja. Zitsulo zamtunduwu nthawi zambiri zimakhala ndi zigawo za Aloy Ch ndi MN. Zolemba zonse za zigawo za Alloy nthawi zambiri zimakhala <5%. Ndioyenera kupanga zigawo zopanga ndi ma batchi ochepa opanga. Zovuta zovuta. Masukulu oimira zitsulo amaphatikizapo A6 kuchokera ku United States, ACD37 kuchokera ku zitsulo, g04 kuchokera ku Akle Chter, etc. Itha kugwiritsidwa ntchito kuti zikhale zozizira zimafa kuti zisadutse ndi kusokonekera. Moyo Wautumiki Wambiri.
Flame idazimitsa chitsulo
Pofuna kufupikitsa kuzungulira kwa nkhungu, kusinthitsa kutentha kwa kutentha, sungani mphamvu ndikuchepetsa mtengo wopanga nkhuni. Japan yapanga ntchito yozizira kwambiri yofa zitsulo kuti ikhale yopanda tanthauzo. Zofanana ndi Aichi SICHI SEEL SX105V (7csimnmov), SX4 (CR8), HATC1, HMD1 Steel, etc.imnmov. Zitsulo zamtunduwu zitha kugwiritsidwa ntchito kutentha tsamba kapena mbali zina za nkhungu pogwiritsa ntchito mfuti ya oxyacetylene pambuyo pake nkhungu zimakonzedwa kenako ndikuzimitsidwa. Nthawi zambiri, itha kugwiritsidwa ntchito mwachindunji pambuyo pokhometsa. Chifukwa cha njira yake yosavuta, imagwiritsidwa ntchito kwambiri ku Japan. Mtundu wachitsulo wamtunduwu wachitsulo ndi 7cssimnmov, yemwe ali ndi vuto labwino. Pamene φ800mm zitsulo ndi mafuta, kuuma patali wa 30mm kuchokera pamwamba amatha kufikira 60hrc. Kusiyana kwa kuuma pakati pa pakati ndi pamwamba ndi 3HRC. Ngati lawi la vwing, mutatha kupanga mu 180 ~ 200 ° C ndi kuthirira mpaka 900-1000 ° °
Kuvuta kwambiri, kuvala koyenera kuvuta
Pofuna kukonza kulimba kwa ntchito yozizira kufa ndi kuchepetsa kuvala kukana kwa zitsulo zopangidwa bwino, makampani ena akuluakulu achilendo apanga ntchito zozizira zazitali ndi kuvuta kwambiri. Zitsulo zamtunduwu nthawi zambiri zimakhala ndi 1% mpweya ndi 8% cr. Ndi kuwonjezera kwa mo, v, si ndi zinthu zina zokongola, ma carbides ake ndi abwino, ndipo amagawidwa motere. . Kuumitsa kwawo, kufooka kwawoku, kutopa mphamvu ndi kulimba mtima kumakhala kokwera, ndipo kukhazikika kwawo kolimba kulinso kuposa chitsulo cha kl2. Ndioyenera nkhokwe yothamanga kwambiri ndi nkhonya yamasuthi kwambiri. Mitundu yamitundu yamitundu yamtunduwu ndi DC53 ya DC53 yokhala ndi v yotsika ndi kuvala bwino ndi v. DC53 imazimitsidwa pa 1020-1040 ° C ndi kuuma kwake kungafike 62-63hrc pambuyo pozizira mpweya. Itha kukhala yodetsedwa pa kutentha kochepa (180 ~ 200 ℃) ndi kutentha kwambiri (500 ~ 550 ℃), kuuma kwake kungakhale kokwera nthawi imodzi kuposa d2; Atatopa kwambiri ndi kugundana, amakhala owoneka bwino komanso opunthidwa pa 850-870 ℃. Osakwana 30 ℃ / ora, atakhazikika mpaka 650 ℃ ndipo adamasulidwa, kuuma kopukutira kumatha kuchitika, ndi sekondale yovuta kwambiri.
Chitsulo chachitsulo (chitsulo chothamanga)
Chitsulo chothamanga kwambiri chagwiritsidwa ntchito kwambiri popanga magwiridwe antchito ambiri, ozizira kwambiri chifukwa cha kuvala bwino kwambiri komanso kuwuma kofiyira, monga kuwuma kwapamwamba kwambiri, kapena ngati valpir wamkulu wa Japan Steal skhople skhol ska skhorn skh51. Kuti tizolowere zofuna za nkhungu, kulimba nthawi zambiri kumayendetsedwa ndikuchepetsa kutentha kwamphamvu, kuthetsa kuuma kapena kuchepetsa zomwe zakhala ndi chitsulo chothamanga kwambiri. Zitsulo za matrix zimapangidwa kuchokera ku chitsulo chothamanga, ndipo kapangidwe kake kwamankhwala kumafanana ndi mawonekedwe a matrix othamanga. Chifukwa chake, kuchuluka kwa ma carbidweture otsalira atatha kuwunjika ndi kufalikira kochepa, komwe kumathandiza kwambiri kuvuta kwa chitsulo poyerekeza ndi chitsulo chothamanga kwambiri. United States ndi Japan adalemba zitsulo zolembedwa ndi ma Crades Vascomna, vascomatrix1 ndi mod2 kumayambiriro kwa m'ma 1970. Posachedwa, DrM1, Drm2, DrM3, ndi zina. Zakonzedwa. Nthawi zambiri amagwiritsidwa ntchito ngati zofunda zamagetsi zomwe zimafuna kulimba kwambiri komanso kukhazikika kwamphamvu. China yapanganso zitsulo zina zoyambira, monga 65nb (65cr4w3w3w3w3vnb), 65w8cr4vTi, 65cr5mo3msiti ndi zitsulo zina. Zitsulo zamtunduwu zimakhala ndi mphamvu komanso kulimba mtima ndipo zimagwiritsidwa ntchito kwambiri popitilira kuzizira, ulusi wakuda umatha, mutu wozizira amwalira, ndi zina zowonjezera.
Ufa wa metalgy nkhungu
Kuzizira kwa Aloy Kugwiritsa Ntchito Chitsulo Kumafa Chitsulo Chopangidwa ndi njira zokhazikika, makamaka zida zazikulu, zomwe zimachepetsa kwambiri, zomwe zimachepetsa mphamvu, zomwe zimachepetsa komanso isotropy ya chitsulo. M'zaka zaposachedwa, makampani akuluakulu achilendo apadera omwe amabala zida ndi kufa zitsulo zokhazikika pakupanga chitsulo chothamanga kwambiri komanso challoy dist steel, yomwe yapangitsa kuti zitsulo zamtunduwu ukhale chitsulo. Pogwiritsa ntchito ufa wa metallitsargy, ufa wachitsulo wowoneka bwino ndipo ma carbides opangidwa ndi abwino komanso yunifolomu, omwe amawongolera mphamvu, wofatsa ndi wasotheptuy wa nkhungu. Chifukwa cha njira yapaderayi, ma carbides ali bwino komanso yunifolomu, ndipo magwiridwe antchito am'madzi amatukuka, kuloleza kuchuluka kwa carbon ndi vadium kuti awonjezereke pazitsulo, ndikupanga mitundu yatsopano ya chitsulo. Mwachitsanzo, mndandanda wa dex wa ku Japan (Dex40, dex60, dex80, ndi zina za FAIKISH Kupanga zitsulo zingapo za ufa monga CPMLV, CPM3V, CPMLOV, CPM15V, ndi zina mwa zinthu zomwe zimapangidwa ndi chitsulo chopangidwa ndi njira wamba.
