I-EN-GJS 400-15 / 500-7 Iibha zentsimbi ezithambileyo | Isinyithi se-Spheroidal Graphite
Intshayelelo yeMveliso
Iibhari zentsimbi ze-EN-GJS 400-15 / 500-7 ze-Ductile Iron ziimveliso zesinyithi ezisebenza kakuhle ezenziwe ngokuhambelana nemigangatho yaseYurophu, ezenzelwe ngokukodwa usetyenziso olufuna amandla aphezulu, ukuguquguquka okuhle, kunye nokusebenza kakuhle koomatshini. Ezi bhari zenziwe ngesakhiwo se-graphite esinobukhulu obuphezulu, esibonelela ngeempawu zokuxinana ezimangalisayo kunye nokumelana nempembelelo, nto leyo eyenza ukuba zibe lukhetho oluguquguqukayo kwiindlela zokusetyenziswa kwesakhiwo kunye noomatshini.
Uthotho lwe-EN-GJS luxatyiswa kakhulu eYurophu ngokunika uluhlu olubanzi lwamandla kunye nokudibanisa ubude. I-EN-GJS 400-15 iphawuleka ngokugudiseka okugqwesileyo kunye nokuqina, ngelixa i-EN-GJS 500-7 inika amandla aphezulu ngelixa igcina ukuguquguquka okwaneleyo. Ezi ntsimbi zentsimbi ezigudileyo zifanelekile kwiindawo ezixineneyo ngokuphindaphindiweyo, ukungcangcazela, okanye ukuchatshazelwa okuphakathi. Ubuchule bazo bokusebenza buzenza zilungele zombini imisebenzi yokurhawuzelela kunye nokugqiba ngokuchanekileyo.
- iibha zesinyithi ezithambileyo zenziwe ngokwemigangatho yamazwe ngamazwe. Iindidi zesinyithi ezisetyenziswa rhoqo zeebha zesinyithi ezithambileyo zibonakaliswa ngeendlela ezahlukeneyo ngokwamazwe ahlukeneyo kunye nemigangatho.
Ezi zilandelayo ziiklasi zentsimbi yentsimbi ethambileyo (amabanga) ezisetyenziswa rhoqo phantsi kweenkqubo ezahlukeneyo eziqhelekileyo:

Ingcaciso yeMveliso
I-Ductile iron bar yinto ephucula iipropati zayo zoomatshini ngokongeza ii-spheroidizing agents ezifana ne-magnesium okanye i-cerium ukuze kuphoswe isinyithi ukuze kwenziwe i-graphite ibe yisakhiwo esingqukuva. Ngokuphathelele ukwakheka kweekhemikhali, izinto eziphambili ze-ductile iron yi-iron, i-carbon, i-silicon, kunye ne-manganese, i-phosphorus, i-sulfur kunye nezinye izinto. Ukongezwa kwee-spheroidizing agents ezifana ne-magnesium okanye i-cerium kubalulekile, okukhuthaza ukwakheka kwesakhiwo esingqukuva kwi-graphite.
