1. Siyini isihlabathi se-ceramic?
isihlabathi se-ceramic senziwa ikakhulukazi ngamaminerali aqukethe i-Al2O3 ne-SiO2 futhi yengezwe nezinye izinto zamaminerali.Isihlabathi se-Foundry esiyindilinga esenziwe nge-powder, i-pelletizing, i-sintering kanye nezinqubo zokugreda.Isakhiwo sayo esiyinhloko sekristalu yi-Mullite ne-Corundum, enomumo oyindilinga wokusanhlamvu, i-refractoriness ephezulu, ukuzinza okuhle kwe-thermochemical, ukwanda okushisayo okuphansi, umthelela kanye nokumelana nokuhuzuka, izici zokuhlukana okuqinile.Isihlabathi se-Ceramic singasetshenziselwa ukukhiqiza ukukhishwa kwekhwalithi ephezulu nganoma yiziphi izinhlobo zezinqubo zokuphonsa isihlabathi.
2. Indawo yesicelo yesihlabathi se-ceramic
Isihlabathi se-Ceramic sisetshenziswe kakhulu ekusungulweni kwezinhlobo eziningi zobuchwepheshe be-foundry, njenge-resin coated sand, inqubo yokuziqinisa (F NB, APNB ne-Pep-set), ibhokisi elibandayo, ibhokisi elishisayo, isihlabathi sokuphrinta se-3D, nenqubo yegwebu elahlekile. .
3. Ukucaciswa kwesihlabathi se-ceramic
I-SND inganikeza isihlabathi se-ceramic sokucaciswa okuhlukahlukene.Ngokwakhiwa kwamakhemikhali, kune-aluminium-oxide ephezulu, izihlabathi ze-aluminium-oxide ephakathi kanye nezihlabathi ze-aluminium-oxide ephansi, ezisebenzisa ngokumelene nezinto ezihlukene zokuphonsa.Zonke zinokusatshalaliswa kosayizi wezinhlayiyana ezihlukene ukuze kwanelise izimfuno zamakhasimende.

6. Izinhlobo zezihlabathi ze-Foundry
Kunezinhlobo ezimbili zesihlabathi se-foundry esisetshenziswa kakhulu, ezemvelo nezokwenziwa.
Izihlabathi ezisetshenziswa kakhulu yi-silica sand, i-chromite sand, i-olivine, i-zircon, isihlabathi se-ceramic kanye ne-cerabeads.Isihlabathi se-ceramic kanye ne-cerabeads isihlabathi sokwenziwa, ezinye ziyisihlabathi semvelo.
7. I-refractoriness yesihlabathi se-foundry ethandwayo
Isihlabathi se-silica: 1713 ℃
Isihlabathi se-Ceramic: ≥1800℃
Isihlabathi se-Chromite: 1900 ℃
Isihlabathi se-Olivine: 1700-1800 ℃
Isihlabathi seZircon: 2430 ℃
