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.

A casting of metal strip by continuous casting in a twin roll caster is provied. In a twin roll caster, molten metal is introduced between a pair of counter-rotated horizontal casting rolls that are cooled so that metal shells solidify on the moving roll surfaces. The twin roll caster is capable of continuously producing cast strip from molten steel through a sequence of ladles positioned on a turret. In casting thin strip by twin roll caster, the crown of the casting surfaces of the casting rolls varies during a casting campaign. The crown of the casting surfaces of the casting rolls in turn determines the strip thickness profile.

A deposition system and method includes a deposition source, a roll conveyor and at least one shield positioned at a location proximate to the deposition source.

An apparatus and method for manufacturing glass include a heat extractor configured to extract heat from molten glass. The heat extractor includes a first conduit and at least one second conduit which may include a plurality of second conduits circumferentially surrounding the first conduit. The first conduit and the at least one second conduit are configured to flow a fluid therethrough.

A roll for use in glass manufacture, such as in the production of non-dusting TFT glass, includes a hollow silica cylinder. A rod extends through the interior of the silica cylinder. A cooling volume is contained within the cylinder and extends around the rod. End caps are mechanically fixed to the roll. Pulling flats are fixed in place by inner and outer end plates. A compression fitting secures at least the outer end plate to the roll. The rod may serve to reinforce the roll and may be secured to the shaft by a plurality of supports. The supports accommodate differences in thermal expansion.

Provide is a heat-resistant roll with improved effectively characteristics, a production method thereof, and a method of producing sheet glass using the heat-resistant roll. A method of producing a heat-resistant roll equipped with a roll portion containing 5% by weight or more of clay includes: a grinding step (S101) of grinding a roll surface of the roll portion; and a surface treatment step (S102) of performing surface treatment of smoothening the ground roll surface in a wet state.
