style="text-indent:25px">采用了球墨復(fù)合鑄鐵軋輥，相對(duì)而言，使用壽命提高了幾倍，至今仍然在使用。國外則一般采用半鋼和高硬度特殊半鋼材質(zhì)，對(duì)克服表面粗糙和抗磨損都很有效。為了提高熱軋輥的表面耐磨性，熱軋輥的材料不斷地得到改進(jìn)，其基本的發(fā)展過程是從冷硬鑄鐵到高鉻鑄鐵到半高速鋼和高速鋼。高鉻鑄鐵軋輥的化學(xué)成分為：2.0%～4.0%Ｃ，10%～30%Ｃｒ，0.15%～1.6%Ｎｉ，0.3%～2.9%Ｍｏ。其本質(zhì)是一種高耐磨性的高合金白口鐵，鉻含量一般在10%～15%，其碳化物主要是Ｍ7Ｃ3型，與白口鑄鐵的連續(xù)的Ｍ8Ｃ型碳化物不同，它不但具有良好的耐磨性，還有較高的硬度(ＨＶ可達(dá)1800)，基體為奧氏體、馬氏體，因而其硬度和韌性結(jié)合較好。軋輥在**終熱處理過程中，對(duì)軋輥鋼的淬火和加熱限制在奧氏體中含碳量不超過0.6%的程度。上海軋輥批發(fā)多少錢</p><p
