Zithunzi za NM400 Mechanical Properties

Miyezo yoyezedwa yazitsulo zamapulasitiki zamagalimoto Rp0.2, Rm ndi A50 zimaperekedwa.

Miyezo yoyezedwa (AKV) yamphamvu yotalika ya mbale yachitsulo pa 0 ° C ndi -20 ° C imaperekedwa.

Kuuma kumagawidwa kukhala: Rockwell hardness, Brinell hardness, Vickers hardness, Richwell hardness, Shore hardness, Barinell hardness, Nooul hardness, Weinwell kuuma. Kuuma kwa Vickers kumawonetsedwa ndi HV, kuuma kwa Rockwell kumatha kugawidwa mu HRA, HRB, HRC, HRD, Brinell kuuma kumawonetsedwa ndi Hb [N(KGF / mm2)] (HBSHBW) (onani GB/T231-1984 ). Si lingaliro losavuta lakuthupi kuyeza kuuma kwa zigawo zachitsulo pambuyo pa annealing, normalizing ndi tempering ndi Brinell kuuma njira kupanga.

Ndilo mndandanda wazinthu zamakina monga elasticity, plasticity, mphamvu ndi kulimba kwa zida. Mayeso a kuuma molingana ndi njira zosiyanasiyana zoyesera atha kugawidwa m'njira zosasunthika (monga kulimba kwa Brinell, kulimba kwa Rockwell, kuuma kwa Vickers, ndi zina), njira zokanda (monga kuuma kwa Mohr), njira yopumira (monga kulimba kwa Shore) ndi micro kuuma, kutentha kwambiri kutentha ndi njira zina.

NM400 Sampling Test

Kuuma mayeso: mphero kuchokera 1.0-2.5mm pamwamba pa mbale zitsulo, ndiyeno kuchita kuuma mayeso padziko. Nthawi zambiri tikulimbikitsidwa kuti mutulutse 2.0mm kuti muyese kuuma.

NM400 Processing

1. Njira yodulira mbale yachitsulo ndi yoyenera kudulira kozizira komanso kudula kotentha. Kudula kozizira kumaphatikizapo kudula jeti yamadzi, kudula, kucheka kapena kudula kwa abrasive; kudula kwamafuta kumaphatikizapo kudula lawi la okosijeni (pambuyo pake amatchedwa "kudula lawi"), kudula kwa plasma ndi kudula laser. .
2. kudula njira: kudzera mayeso oyenera ndondomeko, mbuye makhalidwe ambiri a njira kudula mbale zitsulo ndi kudula makulidwe osiyanasiyana.
3. njira yodulira lawi la chitsulo chosamva kuvala kwapamwamba komanso kutsika kwa carbon ndi kutsika kwachitsulo chochepa cha alloy monga chophweka, mu mbale yachitsulo yosamva kuvala, iyenera kumvetsera !! mbale, chizolowezi chong'ambika cha m'mphepete mwake chimawonjezeka. Pofuna kupewa kutulutsa ming'alu mu mbale yachitsulo, malingaliro otsatirawa ayenera kutsatiridwa podula:

Kudula ming'alu: Mng'alu wodula mbale wachitsulo ndi wofanana ndi mng'alu wopangidwa ndi haidrojeni panthawi yowotcherera. Ngati chitsulo chodulira chitsulo chimachitika, chidzawoneka mkati mwa maola 48 mpaka masabata angapo pambuyo podula.Choncho, ming'alu yodulira ndi ya ming'alu yochedwa, makulidwe ndi kuuma kwa mbale yachitsulo kumakhala kwakukulu, kung'ambika kwakukulu.

Kudula kwa preheat: njira yothandiza kwambiri yopewera zitsulo zachitsulo kudula mng'alu ndikuwotcha musanadulidwe.Asanayambe kudula lawi lamoto, mbale yachitsulo nthawi zambiri imatenthedwa, ndipo kutentha kwake kumayambira makamaka kumadalira mtundu ndi makulidwe a mbale yachitsulo, monga momwe tawonetsera. Table 2. Preheating njira ikhoza kukhala lawi lamoto, magetsi opangira magetsi opangira kutentha, angagwiritsenso ntchito kutentha kwa ng'anjo.Kuti adziwe momwe kutentha kwa chitsulo kumayambira, kutentha kofunikira kuyenera kuyesedwa pa kuwonjezera kutentha.

Taonani: preheating mwapadera, kuti mbale mawonekedwe uniformly usavutike mtima, kuti funsani kutentha gwero la m`dera la kutenthedwa chodabwitsa m`deralo.

Kudula kwa liwiro lotsika: Njira ina yopewera kudula ming'alu ndi kuchepetsa liwiro la kudula.Ngati simungathe kutentha mbale yonse, mungagwiritse ntchito njira yotenthetsera m'malo. preheating.Tikupangira preheating lamba wodula ndi flame gun cavitation kangapo musanadulidwe, ndipo kutentha kwa preheating ndi koyenera kufika pafupifupi 100 ° C. Kuthamanga kwakukulu kumadalira kalasi yachitsulo ndi makulidwe.

Chidziwitso chapadera: kuphatikiza kwa preheating ndi otsika liwiro lawi kudula njira akhoza kuchepetsa mwayi mwina kudula ming'alu.

Zofunika kuziziritsa pang'onopang'ono mutatha kudula: kaya kudulako sikunatenthedwe kapena ayi, kuzizira pang'onopang'ono kwa mbale yachitsulo mutatha kudula kudzachepetsa kwambiri chiopsezo chodula ming'alu. bulangeti, ndi kuzizira pang'onopang'ono kungachitike. Kuziziritsa pang'onopang'ono kumafuna kuziziritsa mpaka kutentha.

Kutentha zofunika pambuyo kudula: kwa kudula avale zosagwira zitsulo mbale, Kutentha (otsika kutentha tempering) amatengedwa mwamsanga pambuyo kudula, amenenso ndi njira yothandiza ndi muyeso kupewa kudula ming'alu.Kudula makulidwe a zitsulo mbale kudzera otsika kutentha tempering mankhwala. , imatha kuthetsa kupsinjika kodulira (njira yochepetsera kutentha; nthawi yonyowa: 5min/mm)

Kwa njira yowotchera pambuyo podula, kuwotcha mfuti, bulangeti lamagetsi lamagetsi ndi ng'anjo yamaliro amagwiritsidwanso ntchito pakuwotcha pambuyo podula.

Ma anti-softening properties a chitsulo makamaka amadalira mankhwala ake, microstructure ndi processing method.Pazigawo zodulidwa ndi thermally, gawo laling'ono, chiopsezo chachikulu chochepetsera gawo lonse.Ngati kutentha kwa mbale yachitsulo kumadutsa 200-250 °C, kuuma kwa mbale yachitsulo kudzachepa.

Njira yodula: pamene mbale yachitsulo ikudula zigawo zing'onozing'ono, kutentha komwe kumaperekedwa ndi nyali yowotcherera ndi kutentha kumasonkhanitsidwa mu workpiece.Zing'onozing'ono kudula kukula, kukula kwa workpiece yodula sikuyenera kukhala osachepera 200mm, mwinamwake workpiece idzakhala kukhala ndi chiopsezo chofewetsa.Njira yabwino kwambiri yothetsera chiopsezo chochepetsera ndi kudula kozizira, monga kudula kwa jet yamadzi.Ngati kudula kwamafuta kuyenera kugwiritsidwa ntchito, kudula kwa plasma kapena laser ndiko kusankha kochepa.Izi ndichifukwa chakuti kudula kwamoto kumapereka kutentha kwambiri. workpiece, motero kukweza kutentha kwa workpiece.

Njira yodulira pansi pamadzi: njira yothandiza kuchepetsa ndi kuchepetsa kukula kwa malo ochepetsetsa, pogwiritsa ntchito madzi ku mbale yachitsulo ya lenga ndi kudula pamwamba pa kudula. popopera madzi kumalo odulira.Plasma kapena kudula kwamoto ndikosankha podula pansi pamadzi.Kudula pansi pamadzi kuli ndi izi:

1. Kutentha kochepa komwe kumakhudzidwa ndi kudula;
2. Pewani kuuma kwa gawo lonse la ntchito kuti lisachepe;
3. Kuchepetsa mapindikidwe a kudula workpiece;
4. The workpiece akhoza utakhazikika mwachindunji pambuyo kudula.
