Taarikada birta ah ee u adkaysata xidhashada:
(1) NM360 (dharka u adkaysta 360)
Magacaabidda: N waa iska caabin (nai) M waa xarafka ugu horreeya ee pinyin ee labada xaraf ee Shiinaha ee shiididda (mo), iyo 360 waxay ka dhigan tahay celceliska adkaanta Brinell ee taarikada birta ah.
Daaweynta kulaylka: heerkulka sare ee heerkulka, deminta + xanaaqa (dejinta iyo xanaaqa)
Codsiga: NM360 xaashida birta u adkaysta ayaa si weyn loogu isticmaalaa mashiinnada macdanta, mashiinnada macdanta dhuxusha, deegaanka
Waxa kale oo caadi ahaan loo isticmaalaa sidii bir qaabdhismeed xoog-sare leh oo leh awood dhalidda ≥ 700MPa.Inta badan waxa weeye in la bixiyo ilaalinta wakhtiyada ama qaybaha u baahan in ay noqdaan kuwo xidhashada adkaysi u leh, si qalabku u yeesho cimri dheer, hoos u dhigida dayactirka ee ay keento dayactirka, iyo si u dhigma loo yareeyo maalgashiga raasamaalka.
Waxqabad: Wax-soo-saarku wuxuu ka badan yahay 800, xoogga xajinta ayaa ka badan 1000.
(2) NM400
NM400 waa taariko bir ah oo aad u adkeysi badan.NM400 waxay leedahay awood farsamo oo aad u sareysa;sifooyinkeeda farsamadu waa 3 ilaa 5 jeer ka badan xaashiyaha birta-daawaha hoose ee caadiga ah;waxay si weyn u wanaajin kartaa caabbinta xirashada ee qaybaha farsamada la xiriira;sidaas darteed wanaajinta nolosha adeegga mashiinnada iyo dhimista kharashka wax soo saarka.Engegnaanta dusha alaabtan waxay badanaa gaartaa 360 ~ 450HB.Taarikada birta qaab dhismeedka lagu dabaqi karo ee farsamaynta iyo soo saarista dharka u adkaysta iyo qaybaha nugul ee miinooyinka iyo mashiinada dhismaha ee kala duwan.
NM400 xaashida birta u adkaysta ayaa si weyn loogu isticmaalaa mishiinada dhismaha, mishiinada macdanta, mishiinada dhuxusha macdanta, mashiinada ilaalinta deegaanka, mishiinada birta iyo qaybaha kale ee alaabta.Qodista, xamuulka, saxan baaldi bulldozer, saxan geeseed, saxan geeseed, daab.Xadhkaha burburiya, garbaha.
(3) Mn13 (birta manganese ee caadiga ah)
Mn13 waa bir u adkaysata manganese sare (HIGH MANGANESE STELL SCRAP), kaas oo ah doorashada ugu fiican ee ka mid ah agabka adkaysiga u leh sida saamaynta adag iyo xidhashada walxaha cadaadiska sare leh.
Waxaa jira laba sifo oo waaweyn oo ah birta manganese-ka sare: mid waa in marka ay weynaato saameynta dibadda, ay sare u kacdo caabbinta xirashada lakabka sare ee u gaar ah.Marka ay saamayso, engegnaantiisa oogada ayaa si degdeg ah uga kordheysa HB200 ilaa ka sarraysa HB700, sidaas awgeed waxay soo saartaa lakab dusha sare ah oo aad u adkaysta.Austenite ee lakabka gudaha ee saxanka birta ayaa wali ilaalinaya adkaanta saameynta wanaagsan;Midda labaad waa iyada oo si tartiib tartiib ah loo xirto lakabka adag ee dusha sare, lakabyo cusub oo adag ayaa sii wadi doona sameynta.
Saxanka birta duuban ee Mn13 waxa uu leeyahay iska caabin heersare ah oo u adkaysta xidhashada xoogga leh iyo xidhashada walbahaarka sare, ma jabi doono inta lagu jiro isticmaalka, oo waxay leedahay sifooyin mashiineed fudud sida goynta, alxanka, iyo foorarsiga.
Caadi ahaan la isticmaalo birta kabka ee chromium-ka sare waxay leedahay iska caabin wanaagsan oo xidhashada kaliya ee xirashada dhaqaaqa.Mn13 saxan bir ah oo duuban ayaa si wax ku ool ah u dhimi karta isticmaalka kharashka xidhashada qaybo ka mid ah qalabka, badbaadinta kharashka dayactirka qalabka, iyo hagaajinta tartanka alaabta la dhammeeyey.
Si kastaba ha ahaatee, caabbinta xirashada birta manganese sare waxay muujineysaa inay ka sarreyso kaliya shuruudaha ku filan si loo sameeyo adkeynta shaqada, waana liidata xaaladaha kale.
Nooca caadiga ah ee Mn17 ee dharka u adkaysta birta sare ee manganese waa in la kordhiyo qadarka manganese iyada oo ku saleysan Mn13 birta, taas oo wanaajisa xasilloonida austenite oo ka hortagaysa roobabka carbides, taas oo hagaajinaysa xoogga iyo caagagga birta iyo hagaajinta shaqada awoodda adag ee birta.iyo caabbinta naaxinta.Tusaale ahaan, nolosha adeegga fargeetooyinka tareenka ee ZGMn18 ee laga isticmaalo waqooyiga ayaa 20% ~ 25% ka sarreeya kan ZGMn13.
Darajooyinka iyo baaxadda codsiga birta manganese sare ee sida caadiga ah looga isticmaalo Shiinaha waa: ZGMn13-1 (C 1.10% ~ 1.50%) waxaa loo isticmaalaa qaybo yar-yar, ZGMn13-2 (C1.00%～1.40%) ayaa loo isticmaalaa qaybaha caadiga ah, ZGMn13- 3 (C0.90% ~ 1.30%) waxaa loo isticmaalaa qaybo adag, iyo ZGMn13-4 (C0.90% ~ 1.20%) waxaa loo isticmaalaa qaybaha saamaynta sare.Maaddada manganese ee afarta darajo ee sare ee birta ah waa 11.0% ilaa 14.0%.
Alxanka iyo hagaajinta, austenite-ku salaysan manganese-nickel electrodes (nooca D256 ama D266) waa in la doortaa, oo leh qeexid dheer oo khafiif ah, φ3.2mm × 350mm, iyo daahan dibadda waa alkaline.Habka qalliinka waxa uu qaadanayaa isku xirka DC-ga rogan, hadda yar, arc daciif ah, ul alxanka yar iyo lakabyo alxanka oo badan, oo had iyo jeer ilaaliya heerkulka hooseeya iyo kulaylka yar.garaac markaad alxanayso si aad u baabi'iso diiqada.Xirmooyinka muhiimka ah waa in la ogaado cillad.alxanka Flash (Swiss GAAS80/700 mishiinka alxanka flash) ama MAG alxanka (sida Nissan YD-S-500) waxa loo isticmaali karaa alxanka aad muhiim u ah, kaas oo si wax ku ool ah u hubin kara in tollayn qalabka farsamada.
Lifaaqa 1: Fikradda adkaanta
Adaggu waa tusaha waxqabadka si loo cabbiro jilicsanaanta iyo adkaanta alaabta.Waxaa jira habab badan oo lagu tijaabiyo qallafsanaanta, mabaadi'da isku mid ma aha, iyo qiyamka qallafsanaanta la qiyaasay iyo macnayaasha ma aha kuwo isku mid ah.Midda ugu badan waa tijaabada adagaanta habka culeyska taagan, oo kala ah Brinell hardness (HB), hardness Rockwell (HRA, HRB, HRC), Vickers hardness (HV), caagga caagga ah ee Shore adag (HA, HD) iyo qallafsanaanta kale Qiimaheeda ayaa tilmaamaya awoodda dusha sare ee maaddada si ay uga hortagto soo dhex-galka shay adag.Adaggu maaha tiro jidheed oo fudud, laakiin waa tusm hawleed dhammaystiran oo ka tarjumaysa barti, balaastigga, xoogga iyo adkaanta alaabta.
Adag ee birta: Magaca koodka ee adkaanta birta waa H. Marka loo eego hababka tijaabada adag ee kala duwan, waxaa inta badan jira tibaaxaha soo socda.
●Odhaahyada caadiga ah waxaa ka mid ah Brinell (HB), Rockwell (HRC), Vickers (HV), Leeb (HL) qallafsanaanta, iwm, kuwaas oo HB iyo HRC inta badan la isticmaalo.
●HB waxay leedahay codsiyo kala duwan oo kala duwan, waxaana guud ahaan loo isticmaalaa marka walaxdu jilicsan tahay, sida biraha aan birta ahayn, birta ka hor daaweynta kulaylka ama ka dib marka la tirtiro.HRC waxay ku habboon tahay maaddooyinka leh engegnaanta dusha sare, sida qallafsanaanta daaweynta kulaylka, iwm.
Farqiga u dhexeeya labada waa in shaybaarrada tijaabiyeyaasha adkeysigu ay kala duwan yihiin.Baarayaasha tijaabiyaha adkaanta Brinell waa kubbado bir ah, halka shaybaarrada tijaabiyaha qallafsanaanta Rockwell ay yihiin dheeman.Shuruudaha qaarkood, HB iyo HRC waa la is weydaarsan karaa iyadoo la eego miiska.Qaabka xisaabinta maskaxeed waxa loo qori karaa qiyaas ahaan sida: 1HRC≈1/10HB.
●HV-ku habboon falanqaynta micnaha yar.adkaanta Vickers (HV) waxaa lagu cadaadiyaa dusha walaxda iyada oo culays ka yar 120kg iyo koofiyad labajibbaaran oo dheeman ah oo leh xagal vertex ah 136 °, iyo aagga dusha sare ee godka galka alaabta waxaa loo qaybiyaa culeyska qiimaha, kaas oo ah qiimaha adag ee Vickers (HV).Adayga Rockwell (HR-) waxaa lagu go'aamiyaa qoto dheer ee qallafsanaanta balaastiigga gelinta si loo go'aamiyo tusmada qiimaha qallafsanaanta.Way fududahay in la shaqeeyo, dhakhso leh oo dareen leh, waxayna ku habboon tahay wax soo saarka ballaaran.
