Qeexitaannada cabbirka GB ee lebennada dib-u-celinta guud
Tilmaamaha cabbirka GB ee guud lebenkii alwaax ahaanta ku shaqeeya
Cabbirrada dibadda ee lebenka refractory inta lagu guda jiro wax soo saarka ayaa inta badan loo qaybiyaa laba xaaladood. Midka kowaad waxa loo fuliyaa iyadoo loo eegayo cabbirka GB ee lebenka refractory ka labaadna waa: cabbirka aan GB ahayn. Cabbirrada aan GB ahayn waxay leeyihiin cabbir leben caadi ah oo qaabaysan, tusaale ahaan, cabbirka dibadda ayaa ka weyn, qaabkuna si weyn isuma beddelo. Si kastaba ha ahaatee, cabbirka qaabka gaarka ah waa kiis isbeddel weyn oo ku yimaadda cabbirka dibadda, iyo wareegga prismatic trapezoidal ama dusha sare ee concave-convex oo leh godadka wareegsan waa leben-qaabeeya. Marka la soo saarayo, waxaa lagama maarmaan ah in la xaddido wax soo saarka caaryada sababtoo ah kharashka wax soo saarka ayaa ka sarreeya cabbirka GB. .
Lebenka dib-u-celinta guud waxa loo qaybiyaa halbeegyo guud iyo tilmaamo qaabaysan iyadoo loo eegayo cabbirada, cabbirrada iyo cabbirrada lebennada refractory. Marka loo eego walxo kala duwan, lebennada guud ee dib-u-celinta waa inay buuxiyaan shuruudaha soo socda;
(1) Wax aan ka badnayn afar miisaan;
(2) Saamiga cabbirrada dibadda ee lebenka refractory waa inta u dhaxaysa 1: 4;
(3) Ma jiraan geeso go’an, godad iyo godadka;
(4) Miisaanku waa 2-8 kg (leben dhoobo ah) iyo 2-10 kg (leben aluminium sare ah) siday u kala horreeyaan.
Silica lebenka, lebenka magnesia iyo leben alumina magnesia, alaabta guud waxay u baahan yihiin in ay la kulmaan kor ku xusan (1), (2), (3), iyo miisaanku waa ka duwan yahay: miisaanka silica leben ujeedo guud waa 2-6 kg. , miisaanka leben magnesia iyo magnesia alumina leben waa 4-10 kg.
Lebennada dib-u-celinta ee qaab-gaar ah ayaa ah alaabo leben refractory ah oo leh cabbirro kala duwan oo ka mid ah tilmaamaha caadiga ah:
(1) Saamiga cabbirrada dibedda waxay ku dhex jirtaa inta u dhexeysa 1: 6;
(2) Waxay leedahay wax aan ka badnayn laba geesood oo iskuxiran (oo ay ku jiraan geeso koofiyad ah oo qaabaysan) ama xagal ba’an oo ah 50o ilaa 75o, ama aan ka badnayn 4 grooves;
(3) Miisaankiisu waa 2-15 kg (leben dhoobo ah) iyo 2-18 kg (leben aluminium sare) siday u kala horreeyaan.
Lebennada silica, lebennada refractory ee qaabka gaarka ah waa inay buuxiyaan shuruudaha soo socda;
(1) Saamiga guud ee cabbirku wuxuu ku dhex jiraa inta u dhaxaysa 1: 5;
(2) Ma laha wax ka badan hal xagal oo concave ah, ama xagal ba’an oo ah 50℃ˉ75℃, ama aan ka badnayn 2 grooves (sida ku cad tirada guud);
(3) Miisaankiisu waa 2-12 kg.
Lebenka magnesia iyo lebenka alumina ee magnesia, lebennada kale ee magnesia iyo lebenka alumina ee magnesia alumina ee aan lagu dari karin qeexida lebenka caafimadka guud waxaa loo yaqaan lebenka refractory qaabaysan.
