Title:
A ROLL ASSEMBLY FOR USE AT HIGH TEMPERATURE AND METHOD OF MAKING SAME
Document Type and Number:
WIPO Patent Application WO1999015305
Kind Code:
A8
Abstract:
A roll assembly (20) for high temperature applications comprising a roll body (22) and trunnions (30) on opposing ends (24) thereof is disclosed. The roll body and supporting trunnions are comprised of alloys having dissimilar coefficients of linear thermal expansion. The trunnions are attached to the roll body so that there is a predetermined gap (40) at room temperature that decreases or closes at a desired operating temperature. The gap decreases due to the dissimilar thermal expansions between the roll body and the trunnions. In certain embodiments, the distance of the gap is determined so there is a tight predetermined interference fit between the trunnions and the roll body for roll assembly integrity and load transfer. In other embodiments, the distance of the gap is determined so that a plurality of mechanical connectors (44) extending between the roll body and the trunnions provide the roll assembly with integrity and provide load transfer between the roll body and the trunnions.
