High Chrome steel roll
The outer layer of the improved high-chromium steel centrifugal composite roller has higher chromium alloy content, and niobium, vanadium, tungsten and other strong carbide elements are added to carry out multi-element alloying; after the roller is subjected to spray quenching and twice tempering heat treatment,The outer layer is composed of tempered martensite and compound granular carbides(M7C3+ MC + M2C + M6C), which can improve the wear resistance of the roll significantly. The core is made of high strength ductile iron, which has excellent comprehensive performance.
