1. Chii chinonzi ceramic jecha?
jecha receramic rinonyanya kugadzirwa nemaminerari ane Al2O3 uye SiO2 uye akawedzerwa nemamwe mamineral zvinhu. A spherical foundry jecha rakagadzirwa nehupfu, pelletizing, sintering uye grading maitiro. Yayo huru yekristaro chimiro ndeye Mullite uye Corundum, ine yakatenderedzwa zviyo chimiro, yakakwirira refractoriness, yakanaka thermochemical kugadzikana, kuderera kwekuwedzera kwemafuta, kukanganisa uye abrasion kuramba, maficha ekutsemuka kwakasimba. Ceramic jecha rinogona kushandiswa kugadzira yakakwirira mhando castings nemhando ipi neipi yejecha maitiro ekukanda.
2. Nzvimbo yekushandisa yejecha receramic
Ceramic jecha rave richinyanya kushandiswa mukutanga kweakawanda emhando dzetekinoroji tekinoroji, senge resin yakavharwa jecha, self-kuomesera maitiro (F NB, APNB uye Pep-set), inotonhora bhokisi, rinopisa bhokisi, 3D kudhinda jecha, uye yakarasika foam process. .
3. Kutsanangurwa kwejecha receramic
SND inogona kupa ceramic jecha remhando dzakasiyana siyana. Nekuumbwa kwemakemikari, kune yakakwira aluminium-oxide, yepakati aluminium-oxide jecha uye yakaderera aluminium-oxide jecha, iyo inoshandisa kurwisa akasiyana castings zvinhu. Vese vane huwandu hwakakura hwakasiyana siyana saizi yekugovera kugutsa zvinodiwa nemutengi.

6. Mhando dzejecha rekuwana
Kune marudzi maviri ejecha rekutanga rinonyanya kushandiswa, rechisikigo uye rekugadzira.
Majecha anowanzo shandiswa ari silica jecha, jecha rechromite, olivine, zircon, jecha receramic uye cerabeads. Ijecha receramic uye cerabeads ijecha rekugadzira, mamwe ijecha rezvisikwa.
7. The refractoriness yakakurumbira foundry jecha
Silika jecha: 1713 ℃
Ceramic jecha: ≥1800℃
Chromite jecha: 1900 ℃
Olivine jecha: 1700-1800 ℃
Zircon jecha: 2430 ℃
