Paper Title:
Wear Characteristics of Spheroidal Carbides Cast Irons in Uniaxial Rotary Glass Shredder
  Abstract

Spheroidal carbides cast irons (SCIs) are used in severe conditions where often occur erosion and due to their excellent wear resistance characteristics. In this study, three kinds of SCIs with a variation in matrices are tested and evaluated as shredding blade of uniaxial rotary glass shredder in recycling factories where often occurs extreme abrasion with the crushed glass. They are SCI-VCrNi, SCI-VMn, and SCI-Vw with hard (2400Hv) spheroidal vanadium carbides (VC). As a result, SCI-Vw reveals excellent wear resistance, approximately 1/12 of wear removal in weight, compare to other two materials of SCI-VCrNi and SCI-VMn. Spheroidal carbides nodularity(70%) and volume fraction of VCs(approximately 20%) are similar in three kinds of SCIs. The hardness of matrix of SCI-Vw (800Hv) is greater than that of SCI-VCrNi (320Hv) and SCI-VMn (380Hv). Therefore the experimental results are interpreted that hardness of matrix are dominant factor for abrasion. Based on this experimental study, SCI-Vw is an effective material for abrasion occurred on the blade of the glass shredder.
