Qaybaha shubka tubbada birta caadadu waxay ka samaysan yihiin bir ductile bir ahhabka shubista ciidda. Ourqaybaha shubidda ciiddawaxay u adeegayaan warshado badan oo baahi badan loo qabo sida saliidda & gaasta, tareenada tareenada iyo baabuurta. Waxaan ku martiqaadeynaa macaamiisheena inuu ku lug yeesho naqshadeynta iyo horumarinta qalabka iyo alaabada bilowga hore. Injineeradayada khibrada leh ee khibrada u leh waxay kaa taageeri karaan fikradda bilowga ah ilaa wax soo saarka taxane ah iyadoo ay jiraan aqoon khibrad u leh wax soo saarka dhabta ah iyo falanqaynta agabka oo ay ku jiraan isku dhafka kiimikaad iyo qalabka farsamada. Kooxdayada injineernimada waxay u rogi doonaan wax kasta oo horumarineed si ay u qaabeeyaan caatada iyo wax soo saarka-saaxiibtinimo iyagoo qaadanaya habkayaga silsilad-soo-saarka oo buuxa.
Birta shubku waa kaarboon kaarboon ka samaysan oo ka samaysan walxo kale kuwaas oo lagu sameeyo dib u dhalaalista birta doofaarka, qashinka, iyo waxyaabo kale oo lagu daro. Si loo kala saaro birta iyo birta shubka, birta shubka ah waxaa lagu qeexaa sida daawaha kabka ah ee ka kooban kaarboon (min 2.03%) taas oo hubisa adkaynta wejiga u dambeeya oo leh isbeddel eutectic ah. Iyada oo ku xidhan tafatirka kiimikaad, biraha shubku waxa ay noqon karaan kuwo aan alloys ahayn ama la isku daray. Baaxadda birta aluminiumku aad ayay u ballaadhan tahay, waxayna ka kooban yihiin ama ka kooban yihiin qaybo badan oo ka mid ah qaybaha caadiga ah, sida silikoon iyo manganese, ama waxyaabo gaar ah, sida nikkel, chromium, aluminium, molybdenum, tungsten, copper, vanadium, titanium, iyo lagu daray. kuwa kale. Guud ahaan, birta kabka waxa loo qaybin karaa bir cawl, bir bir ah (bir nodular), bir cad, bir graphite is haysta iyo birta shubka ah ee la heli karo.
▶ Naqshadeynta iyo Horumarinta Qalabka Kaabista Ciidda iyo Qaababka
Dukaankeena qaabka iyo agabka, farsamayaqaanadeena khibrada u leh naqshadeeyayaasha iyo farsamayaqaanada waxay u isticmaali karaan sawirada 2D iyo moodooyinka 3D horumarinta qalabaynta / qaabka. Haddii ay suurtagal tahay, habka soo jireenka ah ee samaynta ayaa sidoo kale la tixgeliyaa. Khubaradayadu waxay sidoo kale kaa taageeri karaan samaynta moodooyinka 3D sida ku cad fikradaada qallafsan ama sawirada 2D, haddii aad u baahan tahay.
Marka aan naqshadeyno qalabka / patters iyo habka wax soo saarka eeqaybo ciid tuurid, waxaan had iyo jeer ka fikirnaa arrimaha soo socda ee muhiimka ah:
• Miisaanka hoose si loo yareeyo kharashyadaada.
• Cabir sax ah si loo yareeyo ama aan loo baahnayn mashiinka.
• Si fudud loogu rakibo qaybaha kale.
• Qalab ku habboon si loo buuxiyo shuruudaha guryaha farsamada laakiin la xakameeyo dhammaan kharashyada.
• U noqo mid u horseeda wax soo saar ballaaran.
• Deegaanka-saaxiibtinimo.
▶ Metallurgy, Isku-dhafka Kiimikada iyo Qalabka Farsamada ee Qalabka
Foundry ee RMC waxaa lagu qalabeeyay shaybaar macdan dhammaystiran si loo go'aamiyo sifooyinka kiimikada iyo farsamada dhalaal kasta iyo in la falanqeeyo xaaladda birta dhalaalaysa ka hor inta aan la shubin. Qaybaha yar yar ayaa lagu baaro mikroskoob si loo helo macluumaadka ugu dambeeya. Haddii ay suurtagal tahay ama loo baahan yahay, waxaan siin karnaa 3.1 Shahaado qayb kasta oo gaarsiinta iyadoo loo eegayo baahida macaamiisha.
