Design and analysis of sand casting process of mill roller

The quality characteristics of the mill roller in sand casting has been affected by casting defects caused by in proper process parameter usage and intern affects its proper function that lead to large number of shop floor trials, high rate of rejection, and low casting yield. The objective of this research is to design and analyze sand casting The grinding of rolls for the paper mill industry is known to be one of the most difficult grinding operations. These rolls are normally very long relative to outside diameter, hard in compositionGrinding Techniques keeps the Paper and Pulp Industry Rolling

An investigation on the roll force and torque fluctuations during

method of roll force prediction which was based on approximate solutions to the veloc-ity, strain rate and stress distributions in the roll gap. Said, Lenard, Ragab, and Elkhier (1999) determined the roll separating forces and torques via low carbon steel rolling as a function of the area reduction at entry temperatures of 900, 950, 1000, 1050, andAs an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment. This paper provides practical tips on roll inspections, balancing, grinding and grooving. In addition, we discuss proper roll handling during removal, storage, transport, and Practical Roll Techniques Grinding & Balancing Valmet
