Premature failures of such rolls are generally due to surface degeneration, fire cracking, surface indentation and spalling. The surface failures of degeneration, fire cracking and indentation, though progressive in nature, can be remedied by roll grinding operations.

microstructure and wear resistance of high speed steels for rolling .

Abstract. In most cases, work rolls for the finishing stands of hot-strip mills are com- posite components made of an outer shell of cast wear-resistant material and a core of ductile iron or steel. The development of materials for the outer shell has enjoyed rapid advances beginning in the early 1980s, culminating in the.

The higher alloy content in these roll as well as the presence of graphite in the form of spheroids provide in them optimum finish standards. Most nodular iron rolls are chill cast that are a result of hard working layer and softer nects. Further, the alloy content is also precisely controlled to provide a fine & well distributed.

the role of metallurgical defects and microstructure on failure .

IN ROLL NECKS OF CAST IRON ROLLS. 1. INTRODUCTION. Metallurgical rolls are greatly subjected to failure in the roll neck – roll face contact areas, what results from the significant stress concentration in these areas [1]. Cast rolls are particularly subjected to such failures due to their low crack resistance [2–4]. This work.
