Thus roller quantities, equipment a big weight, accounted for about workshop equipment total weight by 20% ~ 30% and sometimes higher. The working conditions of roller directly influences steel-rolling production. The turntable is the purpose of the roller rotation on the stage, so that make them the ingot on the small head above rolling mill, that they can better be plunge into the mill. The turntable roller conveyor consists mainly of two components comprise: stage itself and rotation of the roll machinery, and on Taiwan rotating machinery. This paper is expected early 750 rotary roller mill design, first of its working principle, the purpose is analyzed, thus determine its transmission scheme;And the transmission mechanism, motor, reducer, shaft, rolling bearing, coupling and places a detailed the key link of design calculation;Finally on the turntable roller conveyor attachment through the necessary instructions, including pillar, roller, bolts, and lubrication
