Pyradia designs and manufactured dual-roll mill machines that allow high loading while offering quick roll opening on E-stop for compliance with ANSI OSHA and CSA machine safety codes Category 3 safety features including: safe torque-off quick roll opening body actuated E-stop plate on each side E-stop button on each side and roll nip The torque is equal to the product of total rolling load and the effective moment arm Since there are two work rolls Torque Mt = 2P a Consider two high roll mill as shown in the figure For one revolution of the top roll the resultant rolling load P moves along the circumference of

Roll Torque

Typical roll separating force and roll torque data as a function of the reduction and at various roll surface speeds (20 and 160 rpm leading to surface velocities of 262 and 2094 mm/s) are shown in Figures 9 19–9 21 respectively The lubricants and the emulsions used are also indicated in Figures 9 19–9 21 As expected the roll forces and the torques increase as the

I purchased this mill to replace a worn out 2-roller BC mill that has served me well for almost ten years I was immediately impressed with the size and weight of this unit compared to my previous mill it is solid and appears to be well-built I wanted more capacity so I built a larger hopper using a 5-gallon water jug The first time I used

Because the mill of subject invention can use a smaller work roll than a four high mill it develops a lower separating force and this usually enables a smaller mill to be used for a given duty As an example of this consider the typical cases of rolling of materials 48 in wide with hardness K in the range 50 000 20 to 200 000 lb/in2 and

on wear is another issue Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago the results were never published but of high interest - also maybe later K H Schrder July 2003 K H Schrder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS File: SCHROEDER_ROLLS_010703 DOC

The hydraulic arbor as outlined above presents an opportunity for a manufacturer in the roll-mill coupling business The calculations demonstrate feasibility while the rest of this write-up delineates some useful applications Some fine points of an effective hydraulic arbor will include the following considerations


60 YEARS OF ROLLING MILL TECHNOLOGY By Ford B Cauffiel

including hydraulic screwdowns hydraulic roll bend and tension control This book does not focus on these specific rolling mill manufacturers and their various methods of manufacturing and patentability My intent in this book is to show the modern rolling techniques that

friction μ between the strip and the roll by the following relationship: d max 5 6 Thus as expected the higher the friction and the larger the roll radius the greater the maximum possible draft becomes Note that this situation is similar to the use of large tires (high R) and rough treads (high μ ) on farm tractors

next-generation rolling mill stand FEATURES AND BENEFITS OF THE NEW HYPER UNIVERSAL CROWN-CONTROL MILL FOR HIGHER REDUCTIONS IN COLD ROLLING Primetals Technologies has developed a new Universal Crown-Control Mill (HYPER UCM) that features work rolls with diameters that are 20% to 40% smaller than those used in

The company can now see exactly when the torque spikes and how that relates to the material input to the roll mill system The "High Torque Alarm" function will prevent any further damage to the gearbox thus reducing downtime for the operation

Mill spring is a defect in which the rolled strip is thicker than the required thickness since the rolls get deflected by high rolling forces Elastic deformation of the mill takes place during rolling Mill spring can be avoided if stiffer rolls are used which means that the roll material is having high stiffness or elastic constant Normally
