Insimbi Engagqwali 347 1.4550
Leli shidi ledatha lisebenza kunsimbi engagqwali 347 / 1.4550 ishidi eligoqiwe elishisayo nelibandayo, imicu nemigoqo, imikhiqizo eseqediwe kancane, izinduku nezingxenye kanye nasemashubhu ensimbi angenamthungo nashikelwe ngezinjongo zobunjiniyela bemishini nobujwayelekile.
Isicelo
Ezingxenyeni zokwakha okufanele zimelane nokukala kufika ku-1050°C futhi zifakwe kakhulu emiphumeleni yamagesi e-sulfurous, ikakhulukazi ngaphezu kuka-900°C, ziphansi kakhulu.
