Definitions

  • the invention relates to rolls such as for glass manufacturing.
  • the rolls can convey hot slabs or sheets, as of glass.
  • the rolls typically comprise a steel mandrel and an insulating refractory cover.
  • the cover may be made from materials including refractory fiber, such as ceramic fiber, or compressed millboard.
  • the end assembly of the roll can maintain the roll in compression.
  • a roller conveyor can be made with an inner metal shaft and an outer insulating cover.
  • Asbestos discs can be stacked onto the shaft, and pressed together axially, as discussed, for example, in U.S. Patent No. 3,802,495. The discs can also be pressed together by hydraulic means as taught in U.S. Patent No. 3,1 1 6,053.
  • Ceramic fiber has been successfully used as a replacement for asbestos in certain applications.
  • Annular discs of bulk ceramic fiber are stacked onto an inner metal shaft and may be axially compressed at greater than about 50 percent of the fiber's original density.
  • the compressed discs on the metal shaft may be perfused with colloidal silica and dried.
  • the discs are then recompressed and held permanently in compression.
  • a compression set can be a problem in a refractory fiber roll cover that is held in compression. Compression set is the tendency of a material to shrink under heat and compressive load.
  • U.S. Patent No, 5,307,563 teaches a method of making a roll comprising a mandrel covered by a plurality of resin-impregnated, fibrous discs. Threaded washers tighten along the longitudinal axis of the mandrel to compress the fibrous discs until the resin hardens. However, the patent does not describe tightening after hardening of the resin.
  • Compression set is the tendency of a material to shrink under a compressive load and heat. Along the long axis of the roll, compression set causes the cover to lose its resiliency and rigidity, both of which are necessary to support slabs or sheets.
  • the present invention compensates for compression set while the roll is in operation. Savings to manufacturers can occur from improved efficiency and economy of operation.
  • the end assembly can include a shaft positioned along the axis of the roll and generally outwardly away from the roll.
  • a long, axial compression means can be used in conjunction with the axial shaft. Through this assembly, compressive force can be exerted from a source external to the roller end assembly, onto an end plate of the roll, and then to the fiber cover. Also, positioning means such as setscrews may be used to prevent unwanted movement of the compression means.
  • the invention is directed to a roll structure having a fiber-containing roll cover over a mandrel, which roll structure has at least one end assembly comprising an end plate pressed against the fiber- containing roll cover, a compression element spaced apart from the roll cover by the end plate and abutting against the end plate.
  • the end assembly also compresses a shaft spaced apart from the roll cover on a side of the end plate opposite the roll cover, and elongated compression means at least substantially housed within the shaft which compression means exerts pressure against the compression element.
  • the invention is directed to the method of compressing the fiber of a fiber-containing roll cover having a roll end assembly including an end plate in contact with the fiber-containing roll cover, which method comprises establishing a shaft spaced outwardly away from the roll cover along the axis of the roll, providing compression means associated with the shaft, providing a compression element between the end plate and the compression means, and engaging the compression means with the compression element, while engaging the compression element with the end plate, whereby compressive force from the compression means is transmitted through the compression element and the end plate to the fiber cover.
  • the invention is directed to a roll structure having a fiber-containing roll cover over a mandrel, which roll structure has at least one end assembly comprising an end plate pressed against the fiber containing roll cover, a compression element spaced apart from the roll cover by the end plate and abutting against the end plate, a shaft spaced apart from the roll cover on a side of the end plate opposite the roll cover, and compression means housed within the shaft, the compression means comprising, (a) an elongated rod, (b) a first plate disposed at an end of the rod opposite an external end of the rod, (c) a plurality of springs, and (d) a second plate abutting the compression element, wherein the compression means exerts pressure against the compression element and said end plate to said fiber cover.
  • Fig. 1 is a view in section of a portion only of an insulating roll having an end assembly of the present invention that includes screw compression means that is substantially housed within an axial borehole of an end shaft.
  • Fig. 2 is a view taken along the lines 2-2 of Fig. 1 .
  • Fig. 3 is a view in section of an alternative embodiment of a portion only of an insulating roll having an end assembly of the present invention that includes spring compression means that is substantially housed within an axial borehole of an end shaft.
  • Fig. 4 is a view taken along the lines of 2-2 of Fig. 3. DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • the fiber-containing rolls can find use such as in glass manufacturing. However, they may also be utilized in other processes including metal conveying.
  • the articles in contact with the rolls are typically in the form of slabs or sheets and may be conveyed over the rolls.
  • Metals that may be so processed include steel, aluminum and copper.
  • the fiber useful in the fiber-containing roll cover there will generally be used some ceramic fiber, e.g., from about 20 weight percent.
  • some ceramic fiber e.g., from about 20 weight percent.
  • other refractory fibers which can be synthetic or natural mineral fiber, e.g., synthetic fibers such as glass fiber or carbon fiber, or natural mineral fibers such as asbestos, mineral wool, including mineral wool with additives, or sepiolite, or wallastonite, or fiber mixtures including these natural mineral fibers.
  • synthetic or natural mineral fiber e.g., synthetic fibers such as glass fiber or carbon fiber, or natural mineral fibers such as asbestos, mineral wool, including mineral wool with additives, or sepiolite, or wallastonite, or fiber mixtures including these natural mineral fibers.
  • synthetic fibers such as glass fiber or carbon fiber
  • natural mineral fibers such as asbestos, mineral wool, including mineral wool with additives, or sepiolite, or wallastonite, or fiber mixtures including these natural mineral fibers.
  • the ceramic fiber may be other than a silica-containing fiber, as represented by an alumina fiber or fiber of boron compound material, e.g., fibers of boron oxide, boron carbide or boron nitride. It is preferred for economy that the ceramic fiber be a silica-containing fiber.
  • the silica- containing fiber may simply be silica fiber, although usually the silica is present with one or more of alumina, zirconia, chromia, or titania.
  • Such silica-containing fibers are also meant to include fibers from silicon nitride, silicon carbide, calcium-aluminum silicate and the like.
  • the material used is capable of impregnating the fiber-containing roll, i.e., wicking into the roll, as well as also leaving a residue within the roll on drying, such material is referred to herein for convenience as a 'rigidizer'.
  • Representative rigidizers are such as colloidal silica, colloidal alumina, colloidal zirconia, or similar liquid materials. Where the rigidizer used is in colloidal form, it may be referred to herein as a 'colloidal rigidizer'.
  • the rigidizer may be applied to the fiber to penetrate the fiber, e.g., penetrate completely throughout the fiber. It is however to be understood that penetration may purposefully be limited, such as to only an outermost layer of the compressed ceramic fiber.
  • the ceramic fiber may be prepared by any process useful for preparing ceramic fiber.
  • processes include those which fiberize a molten stream, e.g., blowing of a molten stream to fiberize the molten material, or causing the molten stream to impact rapidly spinning wheels which fiberizes the melt.
  • Commercial manufacture also includes sol-gel processing, e.g., for high alumina fibers.
  • 'shot' refers to the non-fibrous, and usually chunky, ceramic particles that are found in accumulated ceramic fiber, e.g., ceramic fiber blanket.
  • the ceramic fiber may also be processed to have a reduced shot content, e.g., be virtually shot-free.
  • a particularly serviceable ceramic fiber has a Si0 2 content of 54 weight percent, an AI 2 ⁇ 3 content of 43.5 weight percent, an Fe 2 U3 content of 1 .5 weight percent, and one weight percent balance of residual oxides.
  • the refractory fiber such as for ceramic fibers as they are produced, it will be typical that they can be accumulated together. Such may simply be by pressing loose fiber into accumulated form. Accumulated fiber may be fiber accumulated into mats. The mats may have a density on the order of from about 2 to about 8 pounds per cubic foot.
  • the individual fibers in accumulated form may be of varying lengths. All fibers will typically have a length of at least about 0.5 inch, with long fibers usually having length within the range of from about 8 inches up to a length of about 10 inches. A more typical fiber mixture for fibers of varying lengths has some individual short fibers at least about 1 to 4 inches long, in mixture with long fibers.

Abstract

Les cylindres destinés à transporter des feuilles, telles que des feuilles d'acier ou de verre sur un rouleau, comprennent généralement un mandrin en acier et une garniture de cylindre contenant des fibres, la garniture fibreuse étant comprimée entre les plaques d'extrémité. Selon l'invention, un ensemble d'extrémité de cylindre muni de plaques d'extrémité comprend un arbre axial qui s'étend au-delà de la plaque d'extrémité. L'arbre comprend des moyens de compression de cylindre. Les moyens de compression comprennent un élément de compression qui coopère avec la plaque d'extrémité. De cette manière, la pression en provenance des moyens de compression, qui peut être exercée depuis au-delà de l'arbre, peut être transmise au cylindre fibreux.
