Two types of high-speed twin-roll casters and a single-roll caster equipped with scraper were proposed. One the is vertical-type caster, other an unequal-diameter caster. The can cast strip at speeds up to 120 m/min. casts 60 superior point conveyance strip. A without center-line segregation 40 use copper alloy roll non-use parting material enable casting. Since loads these are smaller than 0.1...

This study proposes a way to reduce energy losses in the form of rolling resistance friction during manual wheelchair propulsion by increasing the size of the front caster wheels and adjusting the weight distribution. Drag tests were conducted using a treadmill and a force transducer. Three different casters diameter (4 in., 5 in., and 6 in.) and six different mass distribution combinations (ba...
