Mbale yachitsulo

Ndi chitsulo chathyathyathya chomwe chimaponyedwa ndi chitsulo chosungunuka ndikusaunikizidwa pambuyo pozizira.
Ndi lathyathyathya, makona amakona ndipo amatha kugawidwa mwachindunji kapena kudula mbali zonse.
Pulogalamu yachitsulo imagawidwa molingana ndi makulidwe, mbale yoonda imakhala yochepera 4 mm (yophweka ndi 4,2 mm mm, ndi mbale yowonjezerapo ndi 60-115 mm.
Ma sheet achitsulo amagawidwa kukhala otentha komanso ozizira molingana ndi kugudubuzika.
M'lifupi la mbale yoonda ndi 500 ~ 1500 mm; M'lifupi mwake pepala lazikulu ndi 600 ~ 3000 mm. Ma sheet amasankhidwa ndi mtundu wachitsulo, kuphatikiza chitsulo wamba, chitsulo choyera, chitsulo cham'madzi, chitsulo chosapanga chitsulo, chonyamula chitsulo chotenthetsera, etc.; Pulogalamu ya enamel, bulletproof, etc. Malinga ndi bomba, pali pepala lalikulu, pepala lolemba, pepala lotsogola, lopindika pulasitiki
Zitsulo zotsika
(amadziwikanso ngati chitsulo wamba chotsika, HSLA)
1. Cholinga
Makamaka popanga milatho, zombo, magalimoto, zotupa zapamwamba, mafuta ndi mafuta m'mapaipi a chitsulo, etc.
2. Zofunikira
(1) Mphamvu zazikulu: Nthawi zambiri zimakhala zokolola zake pamwamba pa 300PA.
. Kwa zigawo zazikuluzikulu zokhala ndi mafuta ambiri, kulimba mtima kwamphamvu kumafunikiranso.
(3) Kugwiritsa ntchito bwino magwiridwe antchito komanso kuwongolera kozizira.
.
(5) Kukana zabwino.
3. Makhalidwe Osiyanasiyana
.
(2) Onjezani zinthu zokongola za Manganese.
(3) Kuphatikiza kwa othandizira monga Niobium, Titanium kapena vabium:
Kuphatikiza apo, kuwonjezera pang'ono zamkuwa (≤0.4%) ndi phosphorous (pafupifupi 0,1%) amatha kusintha chipongwe cha kuphulika kwa chimbudzi. Kuphatikiza apo zinthu zochepa kwambiri padziko lapansi zomwe zingawononge ndi dekasi, yeretsani chitsulo, ndikusintha ndikuchita magwiridwe antchito.
4. Zogwiritsidwa ntchito kwambiri zitsulo zotsika
16Mn ndi mtundu wogwiritsidwa ntchito kwambiri komanso wopatsa mphamvu kwambiri. Kapangidwe ka boma kamene kamakhala kofunikira, ndipo mphamvu zake ndi 20% mpaka 30% yoposa imodzi ya mpweya wa kaboni q235, mpaka 20% mpaka 38%.
15mnvn ndiye chitsulo chogwiritsidwa ntchito kwambiri mu zitsulo zapakatikati. Ili ndi mphamvu yayikulu, komanso kulimba mtima kwabwino, kuzizira komanso kutentha kochepa, ndipo kumagwiritsidwa ntchito kwambiri popanga mabwalo, bouls, ndi zombo.
Mphamvu yamphamvu imaposa 500mka, zojambula za Ferrite ndi Pearlite ndizovuta kukwaniritsa zofunikira, zotsika kwambiri kaboni bonitic zimapangidwa. Kuphatikiza kwa KR, Mo, Mn, B ndi zinthu zina ndizothandiza kupeza mawonekedwe a Baine, kuti mphamvu zake ndizabwino kwambiri, ndipo zimagwiritsidwa ntchito kwambiri pakupanikizika kwambiri , mitsempha yayikulu kwambiri, etc.
5. Makhalidwe othandizira kutentha
Zitsulo zamtunduwu nthawi zambiri zimagwiritsidwa ntchito munthawi yodzaza ndi mpweya ndipo sizikufuna chithandizo chapadera. Microstruste yogwiritsa ntchito boma nthawi zambiri imakhala ya Serrite + Sorbite.
Alloy carburized chitsulo
1. Cholinga
Amagwiritsidwa ntchito makamaka popanga magiya otumiza magalimoto pamagalimoto ndi matrakita, makanda, piston zikhomo ndi magawo ena amakina omwe amapezeka mkati. Awiriwa amavutika ndi mikangano yamphamvu ndikuvala ntchito, ndipo nthawi yomweyo amatenga katundu wambiri, makamaka zimakhudzanso katundu.
2. Zofunikira
.
(2) Choyambirira chimakhala cholimba kwambiri komanso mphamvu zokwanira. Pamene kulimba mtima kwa pakati sikukukwanira, ndikosavuta kuswa pansi pa zomwe zimachitika kapena kuchuluka; Mphamvu yamphamvu ikakhala yosakwanira, kufupika kosakoloweka kumasweka mosavuta ndikuyipitsidwa.

20cr harddemated aloy carburized chitsulo. Zitsulo zamtunduwu zimakhala ndi mphamvu zochepa komanso mphamvu zochepa.
20crmmi sipakatikatikati mwanuay alboy carburized chitsulo. Chitsulo chamtunduwu chimakhala chovuta kwambiri, chidwi chachikulu, yunifolomu yofanana ndi kusintha kwa kusintha kwa masinthidwe, komanso makina abwino komanso ukadaulo.
18cr2NI4WA ndi 20cr2NI4A HARDINE HOLOY Carburtering chitsulo. Zitsulo zamtunduwu zimakhala ndi zinthu zambiri monga Cr ndi NI, zimakhala ndi zovuta kwambiri, ndipo zimakhala ndi kulimba kwabwino komanso kutentha kochepa.
5. Chithandizo cha kutentha ndi microstructuction katundu
Njira yothandizira kutentha kwa alloy carburized chitsulo nthawi zambiri imakhala yolimba pambuyo poteteza, kenako ndikusintha kutentha kochepa. Pambuyo pa kutentha, kapangidwe kake kaloya chapamwamba ndi Aloothite + wokwiya wa Steensite + wocheperako wokhalitsa, ndipo kuuma ndi 60hrc ~ 62hrc. Kapangidwe kake kamakhudzana ndi kuumitsa kwa chitsulo ndi kukula kwa gawo la magawo. Ataumitsa mtima, ndiotsika-karborn waku Stenthete wokhala ndi kuuma kwa 40hrc mpaka 48hrc; Nthawi zambiri, ndi Trostite, wachitsulo ndi chitsulo chochepa. Thupi la Element, kuuma ndi 25hrc ~ 40hrc. Kuthekera kwa mtima ndikokwera kuposa 700KJ / m2.
Alloy adazikidwa ndi kukwiya
1. Cholinga
Aluya wowirimitsidwa ndi kukwiya amagwiritsidwa ntchito kwambiri popanga magawo osiyanasiyana pamagalimoto, matrakita, zida zamakina ndi makina ena, shafts, elts, etc.
2. Zofunikira
Ambiri mwa magawo owirimizidwa ali ndi katundu osiyanasiyana ogwirira ntchito, kupsinjika komwe kumakhala kovuta, komanso zinthu zokwanira kumafunikira, ndizofunikira kwambiri komanso chipilala chabwino komanso chipilala chabwino. Aluya ankakhazikika ndipo chitsulo chimafunanso kuuka kwabwino. Komabe, kupsinjika kwa magawo osiyanasiyana kumakhala kosiyana, ndipo zofunikira pakukhazikika ndizosiyana.
3. Makhalidwe Osiyanasiyana
(1) Kabomera wa ma carbon
. Mwachitsanzo, magwiridwe antchito 40cr pambuyo pakuthana ndi kupsa mtima ndikokwera kwambiri kuposa zitsulo 45;
. Kuwonjezera pa mo ndi w kile kungalepheretse mtundu wachiwiri wa bwindless, ndipo zoyenerera zake ndi za 0.15% -0.30% mo kapena 0.8% w.2% w.2% w.2% w.
Kufanizira kwa zinthu za 45 zitsulo ndi 40cr shael pambuyo pothana ndi kusuntha
Steel kalasi ndi kutentha mankhwala a State Gawo / MM SB / MPA SS / MPA y /% ak / m2
45 Steel 850 ℃ Kuzimitsa Madzi, 550
40cr Steel 850 ℃ Kuzimitsa Mafuta, 570

.
. Kuphatikiza kwa Molybdenum sikungakuthandizeni kufooka, komanso kupewa mtundu wachiwiri wa kugwedezeka.
(3) 40CRNIMO Kulimba Kwambiri Kuphatikiza molybdenum yoyenera ku chromium-nickel chitsulo sichokhacho chomwe chimakhala ndi chokhachokha, komanso chimachotsa mtundu wachiwiri wa kugwedezeka.
5. Chithandizo cha kutentha ndi microstructuction katundu
Kutentha komaliza komanso chitsulo chokhazikika ndi chowuma komanso kutentha kwakukulu (kuwumitsa ndi kusala). Alloy owirimitsidwa ndi kukwiya amakhala ndi vuto lalikulu, ndipo mafuta nthawi zambiri amagwiritsidwa ntchito. Kuuluka kumene kuli kwakukulu, kumatha kukhala kokhazikika, komwe kumachepetsa zofooka za kutentha.
Cholinga chomaliza cha alloy chowiringa ndi chitemberero chimadalira kutentha kutentha. Nthawi zambiri, kusunza pa 500 ℃ -650 ℃ kumagwiritsidwa ntchito. Posankha kutentha kwamphamvu, malo ofunikira amatha kupezeka. Pofuna kupewa mtundu wachiwiri wa briticleness, kuzizira kwambiri (madzi ozizira kapena kuzizira kwa mafuta) pambuyo pakusintha kusintha kwamphamvu.
Microstructuctunce of therooy imafinya komanso kukwiya pambuyo pa mankhwala osokoneza bongo azachipatala amakwiya. Kwa zigawo zomwe zimafuna malo osokoneza bongo (monga magiya ndi spindles), kupatsa malo otenthetsera nthaka owundana ndi kuchepa kwa kutentha kumachitika, ndipo mawonekedwe a mantha amakwiya. Kuumitsa kwakumaso kumatha kufikira 55hrc ~ 58hrc.
Mphamvu zokolola zophulika komanso zokwiyira pambuyo pakuthana ndi kupsinjika ndi pafupifupi 800mA, ndi kulimba mtima ndi 800kj / M2, ndipo kuuma kwa pakati kumatha kufika 22hrc ~ 25hrc. Ngati kukula kwa gawo ndi lalikulu ndipo osawuma, magwiridwe antchito amachepetsedwa kwambiri.
