Sababta ugu weyn ee dabka shiida foornada dhalinta dhalaalaysa gariir

Sababta ugu weyn ee gariiradda si ay u dhalaaliso: awoodda ilaalinta ee gariiradda ayaa liidata. Rinjiga dahaadhka ah ee lagu isticmaalo dusha sare ee gariiradda soo noqnoqda ee dhexdhexaadka ah ayaa badanaa ah rinjiga dahaadhka caadiga ah. Xaaladaha qallafsan ee foornada korontada awgeed, diirinta iyo kaarboonaynta rinjiga dahaadhka ah ayaa la ogaaday in uu halis yahay goobta, taas oo ay sababi karaan sababaha soo socda:

a) Dhamaadka ololaha foornada, walxaha dib-u-celinta ee foornada ayaa noqda mid khafiif ah, kulaylka shucaaca ee gariiradda ayaa kordha, heerkulka deegaanka ee gariiradda ayaa noqda mid sare. Rinjiga dahaadhka caadiga ah ma laha iska caabin heerkul sare waana sahlan tahay in la kaarboonaysiyo.

b) Marka foornada korontadu ay garaacdo, birta birta ah waxay ku firdhisaa gariiradda foornada induction, rinjiga dahaadhka ah ee dusha sare ee gariiradda ayaa si toos ah u burburay.

c) Seefka birta dhalaalaysa ee ka timaadda walxaha refractory waxay si toos ah u taabataa dusha sare ee gariiradda oo isla markiiba waxay burburisaa lakabka dahaadhka ah ee dusha sare ee gariiradda. Iyo sababta oo ah varnish dahaarka hadda ma laha iska caabin heerkul sare ah, ma ilaalin karto gariiradda. Birta dhalaalaysa ee heerkulkeedu sarreeyo ayaa si fudud u gubi karta gariiradda si toos ah. Nabarrada qoto dheer ee caadiga ah ee gariiradda ayaa sidoo kale caddaynaya tan.

d) Deegaanka uu ku yaal gariiradda ayaa ah mid aad u daxalaysa, rinjiga dahaadhka caadiga ahi si wax ku ool ah ugama celin karo daxalka, wayna fududahay in uu xumaado oo uu dhaco oo uu lumiyo awoodiisa wax-is-dabamarinta.
