Zozungulira Bar

Bwalo lozungulira (zitsulo zozungulira)ndi amankhwala olimba cylindrical zitsuloamaperekedwa mu utali wowongoka, wofotokozedwa makamaka ndi akeawiri(monga Ø12 mm) ndi momwe amabweretsera (kutentha-kugudubuzika, kukhazikika, kapena kuzimitsidwa & kupsya mtima). Mosiyana ndi chitoliro kapena chubu, ili nayopalibe chobowola-imagwiritsidwa ntchito ngati sitoko yakupanga, kupanga, ndi kupangakupanga ma shafts, mapini, mabawuti, zolumikizira, ndi zida zamakina/makina.

 

Octal Pipe imapereka aloyi ndi zitsulo zapaderamipiringidzo yozunguliraopangidwa ndi zitsulo zazikulu zaku China-zogaya zitsulo, mainchesi kuchokera5 mm mpaka 360 mm, zoperekedwa motentha-zogudubuzika, zokhazikika, kapena zozimitsidwa-ndi-kupsya mtima. Mipiringidzo iyi idapangidwira makasitomala omwe amapanga makina, kupanga, ndikupanga magawo m'magawo monga mphamvu, migodi, madera akunyanja, mayendedwe ndi makina wamba.

Chitsanzo (MTC-yothandizidwa):Satifiketi ya chigayo ili m'munsimu (Ø27 mm × 6 m, 35.916 t chonse) ikuwonetsa chitsulo-chopangidwa ndi alloyed round bar steel chemistry ndi mulingo wamakina womwe umagwiritsidwa ntchito pazigawo zofunika kwambiri. chemistry: pafupifupi 0.33–0.34% C, otsika P ( Ochepera kapena wofanana ndi 0.017%) ndi otsika S ( Ochepera kapena ofanana ndi 0.004%), kuphatikizapo micro-alloying element V, Ti ndi B. Kuphatikiza kumeneko kumatiuza kuti izi ndiayiChitsulo choyambirira, koma amkulu-mphamvu, yabwino-tirigu, yaying'ono-tilalazopangira magawo omwe amafunikira mphamvu zonse (≈950 MPa tensile) ndi kulimba kwamphamvu pa -20 digiri. Mipiringidzo ngati iyi ndi yabwino ngati katundu waiwisi wa ma bolts, ma shaft, mapini, magawo a drivetrain, kubowola ndi zida zamigodi.

M'tsiku-mpaka{1}}kugula zinthu,kuzungulira bar vs ndodokawirikawiri ndiperekani-fomu ndi kuvomerakusiyana osati kusiyana kwa chemistry.Malo ozunguliranthawi zambiri amatanthauza-utali, katundu wa mipiringidzo yolimba yomwe imaperekedwa kuti apange makina ndi kupanga, kumenekulekerera kwa diameter, kuwongoka, ndi mawonekedwe apamwambazimakhudza mwachindunji nthawi yozungulira komanso kuchuluka kwa zidutswa. "Ndodo" Nthawi zambiri amagwiritsidwa ntchito momasuka pama diameter ang'onoang'ono ndipo, kutengera makampani, angatanthauzema coil-mawaya{1}}mafomu a ndodo(zojambula, zopindika, kapena njira za waya) m'malo modula-zitali zazitali.

Njira yothandiza yowalekanitsa ndikuwona zomwe zili zofunika pakulandila:

 

• Ngati mukufunadulani-ku-zosasoweka zazitali kuti mutembenuke/wotopetsa, nthawi zambiri mumagulakuzungulira bar-musamalakuwongoka, decarb, zolakwika zapamtunda, ndi mainchesi osasinthasinthakotero gawo makina mwaukhondo.
• Ngati sitepe yotsatira ndikujambula/kupanga(zopangira mawaya, ma spring, mawaya omangira, ma koyilo-kukonzedwa), "ndodo" nthawi zambiri ndi mawu omwe amagwiritsidwa ntchito, ndipo cholinga chake chimasinthira kumawonekedwe a coil, kuwongolera masikelo, ndi kujambulidwa.

Kuti tsamba liwoneke ngati lovomerezeka, zimathandiza kusonyeza ndondomeko yeniyeni. Njira yodziwika bwino ya -zopiringitsa zozungulira zolimba ili motere:

a) Kupanga zitsulo ndi kukonzanso kwachiwiri
Chitsulo chimasungunuka mu BOF kapena EAF, kenako amachizidwa mu LF/VD kuchotsa sulfure ndi phosphorous ndikusintha zomwe zili mu aloyi molondola. Apa ndipamene ma micro{1}} ma alloying element monga V, Ti ndi B amawonjezedwa. Low P ndi S mu MTC yanu (0.015–0.017% P, 0.003–0.004% S) ndi zotsatira ndendende za sitepeyi - amathandizira kulimba ndi kuwotcherera.

b) Kuponya ndi billet kukonzekera
Chitsulo choyengedwa chimaponyedwa mu ma billets oyenera kugudubuza kapamwamba. Mabilu oyera okhala ndi zophatikizika zochepa ndizofunikira kuti mupambane / kubweza ndikuyesa mayeso omwe amawonekera pa satifiketi yanu.

c) Kutentha kwa bar yozungulira
Mabilu amatenthedwanso ndikugubuduza pa mphero mpaka m'mimba mwake (mwachitsanzo, 27 mm). Kugudubuza kumayendetsedwa kuti mupeze mawonekedwe abwino a pamwamba, kuwongoka komanso kulolerana kowoneka bwino. Mipiringidzo imadulidwa mpaka kutalika kwa malonda, nthawi zambiri 6 m.

d) Chithandizo cha kutentha (kukhazikika kapena kuzimitsa + kutentha)
Kuti mufike pamakina omwe akuwonetsedwa pa satifiketi - 950-960 MPa, zokolola pafupifupi 905-915 MPa, mphamvu yamphamvu pa -20 digiri kuzungulira 100-110 J - mipiringidzo sinasiyidwe "monga yotentha". Amakhala okhazikika kapena, nthawi zambiri pamlingo wamphamvu uwu,kuzimitsa ndi kupsya mtima (Q&T).

Kuzimitsaimapereka dongosolo lolimba la martensitic / bainitic.

KutenthaKutentha koyenera kumabwezeretsa ductility, kumawonjezera kulimba, ndikukhazikika kwa microstructure.
Izi ndi zomwe zimapangitsa mphamvuyo kukhala yokwera koma imasungabe kutalika kwa 13-14% ndikuchepetsa malo opitilira 50%.

e) Kuwongola, kudula ndi kuika chizindikiro
Pambuyo pa chithandizo cha kutentha, mipiringidzo imawongoledwa, kudula mpaka 6 m (kapena utali wina wolamulidwa), kumangidwa ndi kulembedwa ndi manambala a kutentha.

f) Kuyesedwa ndi ziphaso
Wopanga amayesa kuyesa kwa mankhwala, kuyesa kwamphamvu, kuyesa mphamvu pa -20 digiri , kuyesa kwa bend/rebend, kuyesa ndi kuyesa kulimba - ndime zonse zomwe mukuwona pa MTC. Pokhapokha pamene onsewo ali "oyenerera" ndipo mipiringidzo imatulutsidwa. Izi zimapatsa ogula chidaliro kuti mtolo uliwonse umakwaniritsa mulingo wamakina womwe wagwirizana.

 

 

 

Mavuto ambiri azitsulo zozungulira samawoneka pamasamba-amawonekerapa lathe, pambuyo mankhwala kutentha, kapena pa msonkhano. Kwa mapulojekiti omwe amagwiritsa ntchito-mphamvu / yaying'ono-tipiritsi ya alloyed, Octal Pipe imayang'ana kwambiri zinthu zomwe zimasankha ngati balayo ikhala yokhazikika kapena yokwera mtengo yokonzanso:

 

Zomwe nthawi zambiri zimalakwika patsamba	Zomwe mungatchule (chilankhulo chogula)	Zomwe Octal Pipe imawongolera pamphero
Kutha kwa zida zosayembekezereka / kung'ambika	Mkhalidwe wotumizira + zofunikira pamtunda (zotentha-zokulungidwa / zosenda / zokoka)	Njira yokonzekera pamwamba (mwachitsanzo, kusenda komwe kukufunika) + kuwongola kuti muchepetse kusintha kwa makina
Dimensional kutengeka pambuyo Machining	Kulekerera kwa Diameter + Kufunika kowongoka	OD/ovality + cheke chowongoka kuti mupitilize kutembenuza zolosera
Kusweka pazochitika zozizira / zochitika zowonongeka	Mphamvu yamphamvu pa kutentha komwe kwanenedwa (mwachitsanzo, "CVN @ -20 digiri ")	Kuyesa kwamphamvu kumangiriridwa ndi kutentha / zambiri; kumasulidwa kozikidwa pa umboni woyesedwa, osati zongoganizira
Kutentha-kuchepetsa kusagwirizana (kolimba kwambiri / kufewa kwambiri)	Malo ochizira kutentha (okhazikika / Q&T) + zenera lolimba	Kutentha-kuwongolera machiritso + kutsimikizira kuuma kwa zenera lotchulidwa
Zobisika zobisika zapezeka mochedwa	NDT kuchuluka ngati kuli kofunikira (UT mwa mgwirizano)	Njira ya UT pazigawo zofunika kwambiri + kukonza zotsatirika/zosinthanso{1}}zolemba zoyeserera ngati kuli kotheka

 

M'malo mwake, izi zimasintha "kukula kwa bar + grade" kukhala azopangira zogwirira ntchito: bala imafika ndi chikhalidwe chodziwika, machitidwe opangira makina, ndi maziko omasulidwa omwe amafanana ndi momwe magawo amavomerezera. Octal Pipe ikhoza kuthandizira kwambiri-kutengera kufufuza (nambala ya kutentha → zotsatira zoyesa) kotero kuti kulandira kuyendera ndi kuyeneretsedwa kwa makina otsika kumayenda mofulumira popanda kutsanzira kowonjezera.

 

 

Chifukwa nkhaniyi ikuphatikizamphamvu yayikulu (≈950 MPa), ductility wololera (A ≈ 13-14%)ndimphamvu yabwino kwambiri yotsika-kutentha (pafupifupi 100–110 J pa -20 digirii ), itha kugwiritsidwa ntchito m'magawo osiyanasiyana ofunikira:

Zigawo zothandizira migodi, tunnel{0}}zothandizira pansi
Maboliti amiyala, nangula, ndodo zobowola ndi zina zomwe zimayenera kugwira ntchito kuzizira kapena kuzizira-zodzaza. Zokolola zambiri (≈910 MPa) ndi kukhudzika kwabwino kumapangitsa kuti balalo likhale lotetezeka pochita mantha.

Mafuta & gasi ndi zida zakunyanja
Kulumikizani magawo, ma flange, ma hub, ma shaft ndi mabulaketi omwe{0}}kutentha kocheperako ndikofunikira (-20 digiri kapena kutsika). Miyezo yotsika ya P/S ndi mayeso olembedwa zimapangitsa kuti zikhale zosavuta kuvomereza muma projekiti akunyanja ndi m'madzi.

Zimango ndi mphamvu-zigawo zazida
Ma shafts, ma axles, mapini, magiya (pambuyo pa makina owonjezera kapena kuumitsa pamwamba), mafelemu amakina ndi zida zotumizira zomwe zimafunikira mphamvu yayikulu kuposa chitsulo wamba.

Sitimayi ndi zolemera-zagalimoto
Kumene chemistry, traceability ndi weldability (CEV yoyendetsedwa) imafunikira.

Kupanga katundu ndi makina bar
Chifukwa chemistry ndi yoyera komanso kapangidwe kake ndi koyengedwa bwino, bala ndi malo abwino otsekera-mafakitale kapena zida zomangika. Makasitomala atha kupanga chinyengo ndikusungabe kuchuluka kwa makina akamatenthedwanso-.

Ntchito m'madera ozizira
Mphamvu zomwe zatsimikiziridwa za -20 digiri pa MTC zikuwonetsa kuti mipiringidzoyi ingagwiritsidwe ntchito kumpoto / kutsika{1}}malo otentha popanda kulephera.
