Chinese Ceramic Beads yeRCS Application
01
• Kuumbwa kwechikamu chakafanana
• Yakagadzika saizi yezviyo kugovera uye kufema kwemhepo
• High refractoriness (1800°C)
• Kurwisana kwepamusoro kupfeka, kupwanya uye kupisa kwekushisa
• Kuwedzera kuduku kwemafuta
• Kunyorova kwemvura kwakanakisa uye kushanda zvakanaka kwekuzadza nekuda kwekutenderera
• Yakanyanya kudzoreredza mwero mujecha loop system
01
RCS (Resin yakavharwa jecha)
Cold box sand process
3D kudhinda jecha maitiro (Batanidza Furan resin uye PDB Phenolic resin)
Kwete-kubheka resin jecha maitiro (Batanidza Furan resin uye Alkali phenolic resin)
Investment process/ Yakarasika wax foundry process/ Precision casting
Yakarasika uremu maitiro/ Yarasika furo maitiro
