Sharaxaada Alaabta
>>>
Daboolka 7-qaabeeya waa nooc ka mid ah boodhka loo isticmaalo goobta dhismaha, oo leh qaab 7-qaab ah. Waxa kale oo loo yaqaan bolt barroosin saxan la xoojiyey, biraha barroosinka welded, biraha barroosinka cidiyihii, bolt saxan seedaha, boolal barroosin, fur barroosin, silig barroosin, iwm. Waxa si gaar ah lagu aasay in aasaaska shubka ah oo loo isticmaalo sida saldhigga u hagaajinta kala duwan. mashiinada iyo qalabka. Boltanka barroosinka ah ee 7-qaabeeya waa mid ka mid ah biraha barroosinka ee inta badan la isticmaalo. Q235 birta guud ahaan waxaa loo isticmaalaa wax soo saarka, iyo Q345B ama 16Mn alaabta waxaa loo isticmaalaa processing xoog sare, iyo 40Cr alaabta sidoo kale loo isticmaalaa wax soo saarka ee xoogga 8.8-fasalka, iyo sare ama sare birta dunta sare waxaa marmar loo isticmaalaa processing. Dhalooyinka barroosintu waxay u qaybsan yihiin dhogor, ulo qaro weyn iyo ulo dhuuban oo noocyo kala duwan leh. Duufaan, taas oo ah, birta alaabta ceeriin, si toos ah ayaa looga farsameeyaa birta wareegsan ama silig iyada oo aan dib loo habeynin. Usha qaro weyn ayaa sidoo kale loo yaqaannaa nooca A, usha dhuuban waxaa sidoo kale loo yaqaannaa nooca B, kuwaas oo dhamaantood ka sameysan bir ka dib markii dib loo habeeyo dhexroorka usha loo baahan yahay. Albaabada barroosinnada alxanka leh waxaa lagu sameeyaa alxanka saxan bir adag oo leh hal dalool oo madax ah. Iska caabintiisu waa xoog badan tahay. Marka loo eego shuruudaha kala duwan ee isticmaalka, waxay gaari karaan 3.6, 4.8, 6.8, 8.8, iwm. Awooda xajinta ee biraha barroosinka ee si toos ah loogu farsameeyay Q345B ama 16Mn alaabta ceeriin waxay gaari kartaa 5.8 xoogga xajinta.
