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.
