Abstract
A method for making a heat-resistant roll includes pre-selecting a plurality of heat-resistant disks and pressing at least a selected portion of the pre-selected disks together such that a total axial thickness of the pressed disks relative to a total axial thickness of the selected disks prior to pressing is within a predetermined range.
Claims21
A method for making a heat-resistant roll comprising:
- pre-selecting a plurality of heat-resistant disks that each comprise a plurality of wrinkles, the pre-selecting based on at least one quality factor selected from the group consisting of a surface wrinkle density, a surface wrinkle spacing, a surface wrinkle depth, and a void density;
- and
- pressing a number of the plurality of pre-selected heat-resistant disks together, such that a ratio of a total axial thickness of the number of the plurality of pre-selected heat-resistant disks after pressing relative to a total axial thickness of the number of the plurality of pre-selected heat-resistant disks prior to pressing is within a predetermined range.
A method for making a heat-resistant roll comprising:
- pre-selecting a plurality of heat-resistant disks that each comprise a plurality of visible wrinkles, the pre-selecting based on a surface wrinkle density and a surface wrinkle spacing, wherein each heat-resistant disk of the plurality of heat-resistant disks is pre-selected such that the surface wrinkle density of the plurality of visible wrinkles of each heat-resistant disk of the plurality of pre-selected heat-resistant disks is less than about 5 visible wrinkles for any 2,000 square millimeter surface area of the heat-resistant disk, and wherein each heat-resistant disk of the plurality of heat-resistant disks is pre-selected such that the surface wrinkle spacing of the plurality of visible wrinkles of each heat-resistant disk of the plurality of pre-selected heat-resistant disks is at least about 3 millimeters between closest visible wrinkles on the heat-resistant disk;
- and
- pressing a number of the plurality of pre-selected heat-resistant disks together, such that a ratio of a total axial thickness of the number of the plurality of pre-selected heat-resistant disks after pressing relative to a total axial thickness of the number of the plurality of pre-selected heat-resistant disks prior to pressing is within a predetermined range.
