high roll collar

基本解釋

We research the effect of high speed steel compositions, centrifuge casting technology parameter and composite modification on the properties of high speed steel roll collar.
研究了高速鋼成分、離心鑄造工藝參數(shù)和復合變質處理對高速鋼輥環(huán)性能的影響。
Roll collar, needing not only high strength and wear resistance but also thermal fatigue resistance and corrosion resistance, was one of the components which were damaged easily in rolling process.
軋輥不僅需要具備高強度和高耐磨性，還必須具有高的抗熱疲勞強度和耐腐蝕性以及抗氧化性，是軋鋼行業(yè)的主要消耗件之一。
