Chitsulo chachitsulo

Chitsulo chachitsulo
Gulu la Alloy Steel
Malinga ndi zomwe zili
Cholembera chotsika (chonse cha Aloy chimakhala chochepera 5%), sing'anga ya Aloy ndi 5% -10%), zonse zitsulo ndizokwera kuposa 10%).
Malinga ndi mawonekedwe a alloy
Chromium steel (cr-fe-f), chromium-nickel chitsulo (cr-ri-fe-c), manganese-Manganese (SI-MN).
Malinga ndi mawonekedwe ang'onoang'ono kapena kuponyedwa
Pearlite chitsulo, steete chitsulo, ferite chitsulo, chitsulo, chitsulo chamiyendo.
Malinga ndi kugwiritsa ntchito
Alloy amapanga zitsulo zachitsulo, chitsulo cha zitsulo, chitsulo chapadera.
Zitsulo zachitsulo zowerengera
Zomwe zili ndi kaboni zimawonetsedwa ndi nambala yoyambira. Amalembedwa kuti zomwe zili mboni zimawonetsedwa ndi nambala (manambala awiri) m'magawo khumi a chitsulo chambiri ndi chitsulo chimodzi.
Pambuyo powonetsa zomwe zakhala za kaboni, chizindikiro cha chinthucho chimagwiritsidwa ntchito posonyeza chinthu chachikulu chowonera m'chitsulo. Zomwe zili zikuwonetsedwa ndi nambala pambuyo pake. Zomwe pafupifupi zapakati ndizochepera 1.5%, palibe nambala yodziwika. Zomwe pafupifupi pafupifupi ndi 1.5% mpaka 2.49%, 2.5% mpaka 3.49%, etc., 2, 3, ndi zina.
Alloy amajambula 4cr ali ndi zomwe zili mu 0,40%, ndipo zomwe zili mzungu mkolu zimachepera 1.5%.
Chida cha Alloy Steel 5crnmo ali ndi zomwe zili mu 0,5%, komanso zomwe zili zofunikira kwambiri cr, Mn, ndi mochepera 1.5%.
Zitsulo zapadera zimalembedwa ndi zoyambira zam'manja zaku China zomwe zimagwiritsidwa ntchito. Mwachitsanzo: mpira wonyamula zitsulo, zodziwika ndi "g" chisanachitike. GCR15 ikuwonetsa mpira kukhala wachitsulo ndi zokhudzana ndi 1.0% komanso chromium zomwe zili pafupifupi 1.5% (iyi ndi mlandu wapadera, mawu omwe ali pachilichonse amafotokozedwa mu chikwi chimodzi). Y40mmn akuwonetsa chitsulo chaulere ndi zomwe zili ndi miyala 0.4% ndi manganese zokhala zosakwana 1.5%, ndi zina zopatsa chidwi.
Kuyatsa kwa zitsulo
Pambuyo poyatsa zinthu zowonjezera zimawonjezeredwa pazitsulo, zigawo zikuluzikulu za chitsulo, chitsulo ndi kaboni, imalumikizana ndi zinthu zokongola zowonjezerapo. Cholinga cha chisoti chachitsulo ndikusintha kapangidwe kake ndi zinthu zitsulo pogwiritsa ntchito kulumikizana pakati pa zinthu zoyenda ndi chitsulo ndi kaboni ndi kaboni ndi kaboni.
Kugwirizana pakati pa zinthu zokongola ndi chitsulo ndi kaboni
Pambuyo poyatsa zinthu zowonjezereka zimawonjezeredwa pazitsulo, zimakhalapo pazitsulo makamaka mumitundu itatu. Ndiye kuti: kupanga yankho lolimba ndi chitsulo; kupanga carbides ndi kaboni; ndikupanga zigawo za intermettic zokhala ndi chitsulo chamtundu wapamwamba kwambiri.

Zitsulo zojambula
Chitsulo chomwe chimagwiritsidwa ntchito popanga zida zamakina ndi magawo amakina amatchedwa Disoni zitsulo. Nthawi zambiri pamakhala zitsulo zotsika kwambiri, zitsulo zosenda zitsulo zodzala, alonjege ankakhazikika ndi kukwiya, alloy masika achitsulo, ndi mpira wobala zitsulo.
Zitsulo zotsika
1.
2. Zofunikira
(1) Mphamvu yayikulu: Nthawi zambiri, mphamvu zake ndi zokolola zili pamwamba pa 300PA.
. Kwa zigawo zazikuluzikulu zokhalapo, kulimba kwapamwamba kumafunikiranso.
(3) Kugwiritsa ntchito bwino magwiridwe antchito komanso kuwongolera kozizira.
(4) Kutentha kozizira kochepa.
(5) Kukana zabwino.
3.. Makhalidwe Osiyanasiyana
.
(2) Kuwonjezera ma aloy makamaka opangidwa ndi manganese.
.
Kuphatikiza apo, kuwonjezera pang'ono zamkuwa (≤0.4%) ndi phosphorous (pafupifupi 0,1%) amatha kusintha kutsutsana. Kuonjezeranso zinthu zochepa kwambiri padziko lapansi zomwe zingawononge ndi dekasi, yeretsani chitsulo, ndikusintha ndikuchita magwiridwe antchito.
4. Nthawi zambiri amagwiritsa ntchito zitsulo zotsika kwambiri
16Mn ndikugwiritsidwa ntchito kwambiri komanso kupangidwa chitsulo m'dziko langa lotsika kwambiri. Kapangidwe kamene kamagwiritsidwa ntchito ndi ka petiringe-perrite, ndipo mphamvu ili pafupifupi 20% mpaka 30% yopamwamba kuposa kateleka kakang'ono ka kaboni q235, ndi milengalenga mpaka 20% mpaka 38%.
15mnvn ndiye chitsulo chogwiritsidwa ntchito kwambiri mu mphamvu yayikulu. Ili ndi mphamvu zambiri, komanso kulimba mtima, kuyala komanso kutentha-kutentha. Amagwiritsidwa ntchito kwambiri popanga nyumba zazikulu monga milatho, boilers, ndi zombo.
Mphamvu ikaposa 500mA, mbiri ya Perrite ndi yovuta kukwaniritsa zofunikira, zotsika kwambiri-kaboni. Kuphatikiza zinthu monga kor, mo, Mn, ndi B ndiofunitsitsa kupeza mphamvu yozizira yozizira, ndikupanga nyongazo, ndipo magwiridwe owumawo ndi abwinonso. Amagwiritsidwa ntchito kwambiri pantchito yayitali kwambiri, zotengera zapamwamba kwambiri, ndi zina zambiri.
5. Makhalidwe a kutentha
Zitsulo zamtunduwu nthawi zambiri zimagwiritsidwa ntchito munthawi yotentha yolimbana ndi mpweya ndipo sizikufuna chithandizo chapadera. Microstrusm mu ntchito nthawi zambiri nthawi zambiri imakhala ya ferte + perostite.
