Shiinaha Xiro saxan birta u adkaysta BHNM400 BHNM450 BHNM500 soo saaraha iyo alaab-qeybiyaha | Ruiyi
Wear Resistant Steel Plate waxa loola jeedaa badeeco saxan gaar ah oo si gaar ah loogu nashqadeeyay in lagu isticmaalo xaaladaha xidhmo-weyn. Taarikada birta ee sida caadiga ah loo isticmaalo waa badeecado saxan ah oo lagu sameeyo iyadoo la isku darayo dhumuc gaar ah oo ah lakabka dahaarka u adkaysta oo leh adayg sare iyo iska caabin aad u fiican oo dusha sare ee birta kaarboonka hoose ee caadiga ah ama birta daawaha hoose leh adagaanta wanaagsan iyo caagagga iyadoo loo marayo habka korka. Intaa waxaa dheer, waxaa jira taargooyin bir ah oo xirxiran oo kabka ah iyo taargooyin bir ah oo damisan.
Saxan birta u adkaysata waxay ka kooban tahay laba qaybood: saxan bir kaarboon ah oo hooseeya iyo lakabka dahaarka u adkaysta. Lakabka dahaadhka u adkaysta waa guud ahaan 1/3 ~ 1/2 ee dhumucda guud. Inta lagu jiro hawlgalka, matrixku wuxuu bixiyaa sifooyin dhammaystiran sida xoogga, adkaanta iyo caagagga si looga hortago xoogagga dibadda, iyo lakabka alwaax u adkaysta wuxuu bixiyaa sifooyin u adkaysta oo buuxiya shuruudaha xaaladaha shaqada ee cayiman.
Waxa jira xidhiidh bir ah oo u dhexeeya lakabka birta ee birta u adkaysta iyo saxanka salka. Iyada oo loo marayo qalab gaar ah iyo habka alxanka otomaatiga ah, silig-ilaalinta adag ee adag ee is-difaaca ayaa si siman loogu dhejiyaa substrate-ka. Tirada lakabyada isku dhafan waa hal ilaa laba ama xitaa dhowr lakab. Inta lagu jiro habka isku-dhafka ah, iyadoo ay ugu wacan tahay saamiga kala duwanaansho ee kala duwanaansho ee alwaaxyada, dildilaacyo isku mid ah ayaa muuqda. Tani waa astaanta lagu garto ee saxan birta u adkaysata
Lakabka alwaax u adkaysta waxa uu inta badan ka samaysan yahay daawaha chromium, iyo qaybaha kale ee daawaha sida manganese, molybdenum, niobium, iyo nikkel ayaa sidoo kale lagu daray. Carbides ee qaab-dhismeedka birta ah waxaa loo qaybiyaa qaab fibre ah, iyo jihada fiberku waxay ku siman tahay dusha sare. Microhardness-ka carbide wuxuu gaari karaa in ka badan HV1700-2000, iyo engegnaanta dusha sare waxay gaari kartaa HRC58-62. Aloy carbide waxay leedahay xasillooni xoog leh oo heerkul sare ah, waxay ilaalisaa adkaanta sare, sidoo kale waxay leedahay iska caabin oksaydh ah oo wanaagsan, waxaana si caadi ah loo isticmaali karaa gudaha 500 ° C.
Lakabka u adkaysta waxa lagu muujiyaa kanaalada cidhiidhiga ah (2.5-3.5mm), kanaalada ballaadhan (8-12mm), curves (S, W), iwm.; Inta badan waxay ka samaysan tahay chromium alloy, halka ay sidoo kale ku darayso manganese, molybdenum, niobium, nikkel, iyo boron Qaybaha kale ee daawaha, carbides ee qaab-dhismeedka birta ah waxaa loo qaybiyaa qaab fibre ah, jihada fiber-ka ayaa ah mid siman dusha sare. Waxa ku jira carbide waa 40-60%, microhardness-ku waxa uu gaadhi karaa in ka badan HV1700, iyo engegnaanta dusha sare waxa ay gaadhi kartaa HRC58-62.
Taarikada birta u adkaysata waxay inta badan u qaybsantaa saddex qaybood: ujeedo guud, saamaynta u adkaysta iyo noocyada heerkulka u adkaysta; dhumucda guud ee taarikada birta u adkeysaneysa waxay gaari kartaa ugu yaraan 5.5 (2.5+3) mm iyo ugu badnaan 30 (15+15) mm; Taarikada birta xiran xirtaan Tuubooyinka u adkeysan kara ee leh dhexroorka ugu yar ee DN200 waa la rogi karaa oo lagu farsameyn karaa xusulada xirashada, shamacyada u adkaysta, iyo kuwa yareeya xirashada.

Taarikada birta ah ee u adkaysata waxay leedahay caabbi aad u sarreeya iyo sifooyin wanaagsan, waana la gooyn karaa, foorarsan karaa, alxanka, iwm. dayactirka goobta. , ku habboonaanta iyo sifooyinka kale, waxaa si ballaaran loo isticmaalaa in metallurgy, dhuxusha, sibidhka, korontada, galaaska, macdanta, qalabka dhismaha, leben iyo warshadaha kale. Marka la barbardhigo agabka kale, waxay leedahay wax qabad qiimo sare leh waxaana doorbiday warshado iyo soosaarayaal aad u badan.
RAIWELL MFG /TOP Qalabka Birahawaxay keeni kartaa NM360,BHNM400, BHNM450, BHNM500, BHNM550, BHNM600, BHNM650, NR360, NR400, B-HARD360, B-HARD400 (Asal ahaan: Baohua, Wugang, Nangang, Baosteel, Wuhan Iron iyo Steel, Laigang)
Taarikada birta u adkaysata waxay badi u qaybsantaa laba nooc: Biraha birta u adkaysta ee alloy iyo taariko bir ah oo isku dhafan. Taarikada birta ah ee u adkaysata xidhashada waa nm400, JFE-EH400, DILLIDUR 400, iwm. , Samee lakabka daawaha u adkaysta, sidaas darteed waxa kale oo loogu yeeraa saxan bimetallic u adkaysta.
NM500waa saxan bir ah oo u adkaysata xidhashada oo aad u adag oo leh caabbinta xidhashada sare iyo qiimaha adag ee Brinell ee 500 (HBW). Inta badan waxaa loo isticmaalaa in lagu bixiyo ilaalinta waqtiyada ama qaybaha u baahan caabbinta xirashada, taasoo ka dhigaysa qalabku inuu sii dheeraado oo hoos u dhigo kharashka dayactirka.
NM500 saxan bir ah oo xirxiran ayaa si weyn loogu isticmaalaa mashiinnada injineernimada, mashiinnada macdanta, mashiinnada macdanta dhuxusha, mashiinnada ilaalinta deegaanka, mashiinnada birta, aaladaha abrasive, biraha iyo qaybaha kale ee alaabta.
HARDOX450 saxan bir ah oo xidha u adkaysta, 450 waa saxan bir ah oo xidhan oo leh a engegnaanta Brinell ee 450HB waxayna leedahay sifooyin qaloocsan oo qabow. HARDOX 450 waxay leedahay alxan aad u wanaagsan
