MAPIRI AKUCHEPIRIRA OCHEPA
Kukula kwa Chitoliro--1/4” Mwadzina mpaka 42”OD
Makulidwe a Khoma - Ndandanda 10 mpaka XXH
Zitsulo za carbon zotsika kwambiri zapangidwa makamaka kuti zigwiritsidwe ntchito pazida zocheperako komanso makamaka zotengera zowotcherera.
Ndiwotsika-mpaka wapakati-carbon (0.20 mpaka 0.30%), high-manganese (0.70 mpaka 1.60%), zitsulo za silicon (0.15 mpaka 0.60%), zomwe zimakhala ndi njere zabwino zamtundu wa carbide.Amakhala ndi mphamvu zolimbitsa thupi mpaka - 50 ° F (-46 ° C).
Pakuwongolera tirigu ndikuwongolera mawonekedwe ndi kuwotcherera, zitsulo za kaboni zitha kukhala ndi 0.01 mpaka 0.04% columbium.Zomwe zimatchedwa zitsulo za columbium, zimagwiritsidwa ntchito ngati ma shafts, forgings, gears, machine parts, die and gages.Kufikira 0.15% sulfure, kapena 0,045 phosphorous, amawapangitsa kukhala omasuka-machining, koma amachepetsa mphamvu.
LTCS ndi Nickel based alloy steel plates makamaka omwe amagwiritsidwa ntchito pa kutentha kochepa m'munsimu - 150 deg F. Amagwiritsidwa ntchito kwambiri pomanga zombo zapamtunda za cryogenic, kutentha kwapansi kutsika mu zomera za mankhwala pansi -55 deg C.
SA-203 Steel Plate Makalasi A, B, D, E ndi F Nickle Alloy Steel Plates.Kwa kutentha kochepa (-150 deg F)
Kutentha Kwambiri Machubu a Carbon Steel ASTM A334 Gr.1
ASTM A333——Chitoliro Chachitsulo Chopanda Seamless ndi Chowotcherera cha Ntchito Yotentha Yotsika:
Makamaka Giredi
Siredi 1, Siredi 3, Siredi 4, Siredi 6, Siredi 7, Siredi 8, Siredi 9, Siredi 10, Siredi 11;
Low kutentha mpweya zitsulo chitoliro quenching kutentha mu A3 + (30 ~ 50) ℃, mu kuchita, nthawi zambiri anapereka malire chapamwamba.Mkulu kuzimitsa kutentha kutentha chitoliro kungapangitse liwiro lotsika, pamwamba makutidwe ndi okosijeni kuchepetsa, ndipo akhoza kusintha ntchito bwino.The workpiece ndi yunifolomu austenite, adzafunika yokwanira atagwira nthawi.Ngati mphamvu yeniyeni ya ng'anjo yoyikapo, iyenera kukhala yoyenera kuwonjezera nthawi yogwira.Apo ayi, pangakhale kuuma kosakwanira chifukwa cha kutentha kosiyana komwe kumachitika chifukwa cha chodabwitsacho.Komabe, nthawi yogwira ndi yayitali kwambiri, idzawonekanso mbewu zowoneka bwino, makutidwe ndi okosijeni ndi ma decarbonization azovuta zomwe zimakhudza kuzima.Tikukhulupirira kuti ngati anaika ng'anjo ndi wamkulu kuposa ndondomeko zikalata, Kutentha akugwira nthawi anawonjezera 1/5.
Low kutentha mpweya zitsulo chitoliro chifukwa otsika hardability, ayenera kutengera lalikulu kuzirala mlingo 10% mchere.workpiece m'madzi, ayenera kuumitsa, koma osati ozizira, ngati 45 # mwatsatanetsatane zitsulo chilled mu brine, n`zotheka akulimbana workpiece, ndi chifukwa pamene workpiece utakhazikika pafupifupi 180 ℃, ndi austenite mofulumira anatembenukira kwa kavalo thupi. minofu chifukwa cha kupsyinjika kwakukulu.Choncho, pamene chitsulo chozimitsira ndi kutentha chikazizira mofulumira mpaka kutentha, njirayo iyenera kutengedwa kuti muchepetse kuzizira.
Popeza kutentha kwa madzi kumakhala kovuta kumvetsetsa, kuyankhapo pakugwira ntchito, madzi akasiya kutulutsa zinthu zakale, mutha kuthirira utakhazikika (mwachitsanzo, choziziritsa mafuta chingakhale bwino).Komanso, workpiece m'madzi, zochita zoyenera ziyenera kukhala mogwirizana ndi geometry ya workpiece, monga thupi wokhazikika.Sing'anga yozizira komanso yoyima, zomwe zimapangitsa kulimba kosafanana, kupsinjika kosafanana ndikusiya kupunduka kwakukulu kwa chogwiriracho, ngakhale kusweka.
