Qeexida xaashiyaha bir kulul ee la duubay
Xaashida birta kulul ee la duubay oo leh qaab kor loo qaaday dusha sare. Qaabka kor loo qaaday waxaa loo qaabeeyey sidii rhombus, digirta ama digir. Ma jiro hal nooc oo qaab ah oo ku yaal xaashida birta ee jeexan, laakiin sidoo kale waa mid adag oo ka mid ah laba ama in ka badan laba nooc oo qaab ah oo ku yaal dusha sare ee xaashida birta ee la hubo. Waxaa sidoo kale loo yeeri karaa xaashiyaha birta ee Grid.
Isku-darka kiimikada ee xaashiyaha bir kulul ee la duubay
Xaashidayaga ugu kulul ee kulul ee birta leh ayaa sida caadiga ah loo rogayaa birta Qaab dhismeedka Carlbon ee caadiga ah. Qiimaha kaarboonka ayaa gaari kara wax ka badan 0.06%, 0.09% ama 0.10%, qiimaha ugu badan waa 0.22%. Qiimaha 'Silicon' wuxuu u dhexeeyaa 0.12-0.30%, qiimaha manganese qiimaha manganese wuxuu u dhexeeyaa 0.25-0.65%, iyo qiimaha fekprorus iyo sulfur-ka ayaa caadi ahaan ka yar 0.045%.
Xaashida ugu kulul ee birta ee kulul ee la duubay ayaa leh faa'iidooyin kala duwan, sida quruxda muuqaalka, iska caabbinta caabbinta iyo keydinta aaladda jeegga, sicirka qaabka ugu kulul ee jeexan, dhererka qaababka waa in la tijaabiyaa.

Codsiga saliida kulul ee la duubay
Xaashida ugu kulul ee bir ee kulul ayaa badanaa loo isticmaali karaa warshadaha dhisida-dhisida, kuleylka, gawaarida, tareenka, tareenka iyo qaab dhismeedka. Faahfaahinta, waxaa jira baahiyo badan oo loogu talagalay xaashiyaha bir ee kulul ee la duubay si loo sameeyo dabaqa, jaranjarada is-weydaarsiga, barkadda loo yaqaan 'pedol pedur', sagxadda maraakiibta, dabaqa gaariga iyo wixii la mid ah.
Xirmo & gaarsiin kulul
Alaabada loo diyaariyo xirxiran waxaa ka mid ah: xariiq dhuuban oo bir ah, suun bir bir ah ama bir bir ah, warqad farshaxan ama xaashi xaashi ah.
Saxanka kulul ee kulul ee la duudduubay waa in lagu duubaa warqad farsamo ama xaashi xaashi ah oo dibaddeeda ah, waana in lagu xidhaa xarig bir ah oo ciriiri ah, iyo laba xarig oo bir ah oo ku yaal jihada dhaadheer, iyo saddexda kale ee xargaha ah ee jihada kale. Intaa waxaa sii dheer, si loo hagaajiyo xaashida birta ee kulul oo laga fogaado xargaha geeska waa in la jebiyaa, suumanka birta birta ah waa in lagu dhejiyaa squach sparent step stentan geeska. Dabcan, xaashiyaha ugu kulul ee kulul ee jeexan ayaa lagu xiri karaa iyada oo aan lahayn warqad farshaxan ama xaashi xaashi ah. Waxay kuxirantahay shuruudaha macaamiisha.
Iyadoo la tixgalinayo gaadiidka ka yimaada Mill ilaa Loading Deked, gaariga ayaa sida caadiga ah loo istcimaali doonaa. Iyo tirada ugu badan ee xamuul kasta waa 40 mt.
