Tubooyinka alxanka leh ee tuubooyinka dhulka hoostiisa mara ee EN10219
Ourdhuumaha alxanka leh ee wareegsanayaa ah xalka ugu habboon ee mashaariicda halkaas oo iska caabinta daxalka iyo sharafta qaabdhismeedka ay muhiim u yihiin. Habka alxanka ee gaarka ah ma aha oo kaliya in uu kor u qaado xoogga tuubada, laakiin sidoo kale wuxuu bixiyaa dusha aan kala go 'lahayn, isagoo yareynaya khatarta daadinta iyo guuldarrooyinka. Tani waxay ka dhigaysaa inay si gaar ah ugu habboon yihiin bay'ada adag ee inta badan la kulma codsiyada dhulka hoostiisa.
Heerka EN10219 wuxuu hubinayaa in tuubooyinkayaga lagu soo saaray si sax ah oo tayo leh, iyadoo la hubinayo inay u adkeysan karaan cadaadiska iyo caqabadaha gaadiidka gaaska dabiiciga ah. Diirada saara adkeysiga iyo isku halaynta, tuubooyinkayada alxanka leh waxaa loogu talagalay inay bixiyaan waxqabad waqti dheer, yaraynta baahida dayactirka iyo beddelka joogtada ah.

a. Habka deoxidation waxaa loo qoondeeyey sida soo socota:FF: Bir si buuxda loo dilay oo ay ku jiraan curiyayaasha isku xidha nitrogen ee xaddi ku filan in lagu xidho nitrogen la heli karo (tusaale min. 0,020 % wadarta Al ama 0,015 % Al milmaya). b. Qiimaha ugu sarreeya ee nitrogen ma khuseeyo haddii ka kooban yahay kiimikaad uu muujiyo wadarta guud ee Al content ee 0,020 % oo leh ugu yaraan saamiga Al/N ee 2:1, ama haddii ay jiraan walxo kale oo N-xidhi kara. Qodobbada N-ku-xidhan waa in lagu diiwaan geliyo Dukumentiga Kormeerka. |
Marka laga soo tago dhismahooda qallafsan, tuubooyinkani waa kuwo miisaankoodu fudud yahay oo si fudud loo maarayn karo, taas oo ka dhigaysa rakibidda mid waxtar leh oo kharash-ool ah. Haddii aad samaynayso mashruuc tuubooyin cusub ama aad horumarinayso nidaam jira, tuubooyinkeena alxanka leh waxay bixiyaan isku darka qumman ee xoogga, dabacsanaanta, iyo u hoggaansanaanta heerarka warshadaha.
U dooro dhuumahayada alxanka leh ee baahida dhuumaha gaaska dhulka hoostiisa oo khibrad maskaxda ku haysa oo la socota isticmaalka alaabada buuxisaEN10219heerarka. Ku kalsoonow sida ay nooga go'an tahay tayada iyo waxqabadka si loo xaqiijiyo badbaadada iyo waxtarka kaabayaasha gaaska.
