Icyuma kitagira umwanda 347 1.4550
Uru rupapuro rwamakuru rukoreshwa mubyuma bitagira umwanda 347 / 1.4550 urupapuro rushyushye nubukonje buzengurutswe, impapuro n'utubari, ibicuruzwa bitarangiye, inkoni n'ibice kimwe no kubitereko byicyuma bidafite ubudodo kandi busudira kubwubukanishi rusange.
Gusaba
Kubice byubwubatsi bigomba kwihanganira gupima kugera kuri 1050 ° C kandi byatewe cyane ningaruka za gaze ya sulfuru, cyane cyane hejuru ya 900 ° C, ni hasi cyane.
