Itholakala ngezinhlobo eziningana, okuhlanganisa izigaxa, ama-granules, impushana, nocingo olunamakhodi. Ukukhethwa kwefomu kuncike ekufakweni okukhethekile kanye nempahla yomjovo esetshenziswa imboni yensimbi. Intambo enezintambo iya ngokuya iduma ngokunemba nokusebenza kahle kwayo.

Ingabe i-calcium silicon iphephile ukuphatha?

Iphephile uma iphathwa ngezinyathelo ezifanele. Abasebenzisi kufanele bagweme ukuthintana namanzi futhi bagqoke izinto zokuzivikela ukuze bagweme ukuhogela uthuli. Ukulandela imihlahlandlela yokuphepha emisiwe nezimiso zesitoreji kunciphisa ubungozi obuhlobene nokusebenza kabusha kwayo.

Isiphetho kanye Nezincomo Zochwepheshe

I-silicon ye-calcium ime njengento eyisisekelo yensimbi yesimanje, ukuvala igebe phakathi kwensimbi eluhlaza encibilikisiwe kanye nemikhiqizo yensimbi esebenza kahle kakhulu. Ikhono layo eliyingqayizivele lokukhipha i-oxidize ngesikhathi esisodwa, ukukhipha i-sulfurize, kanye nokuguqula okufakiwe kuyenza ingenakuthathelwa indawo ekuphishekeleni ukuhlanzeka kwensimbi nokusebenza kahle.

Kwabenzi bensimbi nama-foundries, ukusetshenziswa kwamasu kwale alloy kuhumusha ngokuqondile ikhwalithi yomkhiqizo ethuthukisiwe, isikhathi sokuphumula esincishisiwe, kanye nezindleko zokukhiqiza eziphansi. Ukuthi isetshenziswa ngendlela eyinhlama ekwelapheni i-ladle evamile noma njengentambo enezintambo ukuze umjovo onembile, inani elilengezayo enqubweni yokukhiqiza ayinakuphikwa.

Uma ubheke ukuthuthukisa imisebenzi yakho yokwenza insimbi, ukuhlola isu lakho lamanje lezengezo kuyisinyathelo sokuqala. Cabangela ukushintshela ekuhlanzekeni okuphezulu i-calcium silicon amamaki noma ukusebenzisa ubuchwepheshe bokuphakela ngocingo ukuze kwandiswe amanani okuthola kabusha. Ukubambisana nabahlinzeki abathembekile abathobela izindinganiso eziqinile zekhwalithi kuqinisekisa ukusebenza okungaguquki futhi kusekela imigomo yakho yokukhiqiza yesikhathi eside.
