1. Xulashada Walxaha Cayriin
Birta birta ah ama birta qashinka ah ee tayo sare leh ayaa la doortaa si loo hubiyo in halabuurka kiimikada uu buuxiyo shuruudaha ASTM A709.
2. Samaynta birta
Hababka Foornada Oxygen-ka ee Aasaasiga ah (BOF) ama Foornada Korontada (EAF) ayaa loo isticmaalaa in lagu dhalaaliyo walxaha ceeriin ah.
Walxaha isku-darka sida manganese, silicon, copper, nickel, iyo chromium ayaa lagu daraa si loo gaaro heerka iyo sifooyinka la rabo.
3. Jilidda
Birta dhalaalaysa waxaa lagu shubaa looxyo iyadoo la adeegsanayo habab shubid joogto ah ama qaabab shubid ah.
4. Duubista Kulul
Suunka waxaa lagu kululeeyaa heerkul sare (~1200°C) waxaana lagu duubaa saxaarado dhumucdoodu iyo ballaca loo baahan yahay leh.
Rogidda iyo qaboojinta la xakameeyey waxay xoojisaa sifooyinka farsamada sida xoogga wax soo saarka iyo adkeysiga.
5. Daaweynta Kulul (haddii loo baahdo)
Darajooyinka qaarkood (tusaale ahaan, HPS) waxaa laga yaabaa in la damiyo oo la kululeeyo si loo hagaajiyo xoogga, adkeysiga, iyo alxanka.
6.Daawaynta Dusha Sare
Saxannada waa la khafiifiyaa (qasacadaynta, gubashada rasaasta) si looga saaro lakabka oksaydhka loona diyaariyo habayn dheeraad ah ama dahaadh.
7.Jarista iyo Dhammaystirka
Saxannada waxaa loo gooyaa cabbirro cayiman, la kormeeraa, oo la tijaabiyaa sifooyinka farsamada, halabuurka kiimikada, iyo saxnaanta cabbirka sida waafaqsan heerarka ASTM A709.
8. Xakamaynta Tayada iyo Kormeerka
Saxan kasta wuxuu maraa tijaabo adag:
Tijaabooyinka xoogga jilicsanaanta iyo wax soo saarka
Imtixaanada saameynta Charpy
Baaritaanka Ultrasonic ama Ultrasound ee cilladaha gudaha
Kormeerka cabbirka iyo dusha sare
9. Baakadeynta iyo Bixinta
Taarikada la dhammeeyay waa la xirxiraa, la calaamadeeyaa, waxaana loo diyaariyaa in loo raro macaamiisha ama goobaha dhismaha.
Taarikada birta ah ee STM A709 badanaa waa taarikada birta ah ee qaab-dhismeedka oo xoog badan, oo aan daawad lahayn oo loogu talagalay in loo isticmaalo buundooyinka iyo codsiyada kale ee dhismaha ee culus. Isku-darka xooggooda, adkaysigooda, iyo alxanka ayaa ka dhigaya kuwo ku habboon mashaariicda kaabayaasha dhaqaalaha ee muhiimka ah.

1. Baakad Xirmo oo Is dulsaaran
Taarikada birta ah waxaa loo kala saaraa oo si fiican loo dul saaraa iyadoo loo eegayo cabbirro iyo tilmaamo kala duwan. Meelo kala fog oo alwaax ah ama bir ah ayaa la geliyaa inta u dhaxaysa lakab kasta si loo ilaaliyo in taarikada siman tahay, looga fogaado taabashada tooska ah iyo in laga hortago waxyeelada is jiidjiidka dusha sare. Dhammaan xirmooyinka la isku dhejiyay waxaa si adag loogu xiraa xarig bir ah si loo hubiyo xasilloonida guud inta lagu jiro safarka iyo in laga fogaado in la beddelo ama la dabciyo.
2. Baakadaha Saxanka iyo Baakadaha
Taarikada birta ah ee cabbirka yar iyo heerka sare leh waxay qaataan xalal baakad alwaax ah ama xalal baakad oo balaastig ah. Warqad iyo filim balaastig ah oo aan miridhku u adkaysan karin ayaa lagu dahaadhay baakadaha si loo ilaaliyo qoyaanka iyo daxalka. Habkan baakadaha dhoofinta ee caadiga ah wuxuu fududeeyaa rarista, dejinta iyo maaraynta bakhaarka, wuxuuna si buuxda ula qabsanayaa gaadiidka caalamiga ah iyo kaydinta dibadda ee muddada dheer.
3. Baakadaha Rarista Badan
Taarikada birta ah ee waaweyn iyo kuwa waaweyn waxaa lagu keenaa gaadiid badda ama dhulka ah. Baloogyada barkimooyinka alwaaxa ah iyo agabka ilaalinta xirfadeysan ayaa lagu mariyaa meelaha ay taarikada ku kulmaan. Tani waxay si wax ku ool ah u ilaalisaa soo bixidda iyo isku dhaca inta lagu jiro gaadiidka, iyadoo ilaalinaysa dusha sare ee taarikada birta ah iyo guud ahaan isku-dhafka dhismaha.
Iskaashiga xasilloon ee shirkadaha maraakiibta sida MSK, MSC, COSCO si hufan silsiladda adeegga saadka, silsiladda adeegga saadka ma ku qanacsan tihiin.
Waxaan raacnaa heerarka nidaamka maaraynta tayada ISO9001 dhammaan habraacyada, waxaanan leenahay xakameyn adag laga bilaabo iibsashada agabka baakadaha ilaa jadwalka gaadiidka.
1. Waa maxaySaxan bir ah oo ASTM A709 ah?
ASTM A709 waa saxan bir ah oo qaab-dhismeedkiisu xoog badan yahay oo si caadi ah loogu isticmaalo dhismaha buundooyinka iyo kaabayaasha dhaqaalaha ee culus. Waxay bixisaa xoog wanaagsan, adkeysi, iyo iska caabbinta cimilada, taasoo ka dhigaysa mid ku habboon jawiga bannaanka iyo kuwa adag.
2. ASTM-ka ayaa la iibin karaaSaxan bir ah oo A709 ahlagu tolayaa?
Haa. Waxaa lagu alxami karaa hababka caadiga ah. Saxannada qaro weyn ama alxamida heerkulka hooseeya, waxaa laga yaabaa in loo baahdo in la kululeeyo kahor iyo daaweynta kulaylka alxamida kadib. Saxannada heerka cimilada waxay u baahan yihiin kontaroolo alxamida oo adag.
3. Cabbirrada iyo dhumucda noocee ah ayaa la heli karaa?
Dhumuc: 6–250 mm; Ballac: Ugu badnaan 4000 mm; Dhererka: Ugu badnaan 12000 mm, ama cabbirro kale ayaa la jari karaa si loo dalbado.
4. Waa maxay faraqa u dhexeeya ASTM A709 iyo ASTM A36?
Iyada oo ay ugu wacan tahay xooggeeda sare iyo adkeysigeeda wanaagsan, ASTM A709 waxaa loo arkaa doorasho ku habboon buundooyinka iyo dhismayaasha culus. ASTM A36 waxay ku habboon tahay codsiyada qaabdhismeedka iyo guud ahaan.
5. Sidee loo sameeyaa baaritaanka?
Tijaabada xoogga jiidista, tijaabada saamaynta (heerkulka hoose), falanqaynta halabuurka kiimikada, kormeerka cabbirka iyo dusha sare.
6. Maxaad u dooranaysaa ASTM A709?
"Sababtoo ah waxaa loogu talagalay codsiyada waxqabadka sare leh ee buundooyinka iyo kaabayaasha dhaqaalaha ee baahida badan. ASTM A709 waxay bixisaa xoog sare, alxan wanaagsan, iyo tayo sare, waxqabadkeeda guud ee aadka u wanaagsanina wuxuu ka dhigayaa mid ku habboon buundooyinka guud, buundooyinka horumarsan, iyo dhismayaasha culus," Bagwell ayaa yiri. Isku-darka xoogga sare, adkeysiga, iyo waxqabadka la xaqiijiyay ayaa ka dhigaya mid ku habboon buundooyinka iyo codsiyada dhismaha ee cimriga dheer, gaar ahaan deegaannada adag.
