Intengo ephansi i-Foundry i-slag ekhethekile evela e-China High viscosity nokukhetha kalula i-slag kungathuthukisa ikhwalithi yokuphosa

Intengo ephansi i-Foundry isklag esikhethekile esivela eChina Fast kanye nokusabalala okufanayo, ukuphendula okusheshayo, ikhono eliqinile lokuqoqa i-slag, i-viscosity ephezulu, I-conjunctiva enhle, elula ukukhetha i-slag, iqinisekisa ubumsulwa kwesisombululo sensimbi futhi ithuthukise ikhwalithi yangaphakathi ye-casting. Into yayo eluhlaza ingamaminerali omlotha wentaba-mlilo; ingxenye eyinhloko yi-SiO₂ (silica), okuyi-pumice enesihlabathi esimhlophe.
