Severe Screw Wear of CMC Extruder
Sorun Belirtisi
After 200h of CMC extrusion, the wear of screw and barrel reaches 0.5mm
Neden Analizi
Filler causes large wear on the screw; screw material hardness is insufficient and not nitrided; high processing temperature causes CMC to adhere to the screw and aggravate wear
Çözüm
1)Use nitrided screw or bimetallic screw SK-2 alloy; 2)Reduce processing temperature to reduce adhesive wear; 3)Treat filler with coupling agent to reduce friction; 4)Regularly check wear and replace in time when >0.3mm
Temel Çıkarım
Screw wear is caused by filler friction and adhesion; wear-resistant screw and temperature control are the key
