<p>[QUOTE=&quot;imrich, post: 2664807, member: 22331&quot;]I&#039;m to understand that you multiple pass calender your planchet sheets from a ~32 ounce Silver ingot/billet at a fixed speed of ~15 feet/minute. What maximum thickness variation can be achieved per pass? What type are the calender roll bearings (e.g. sleeve, roller, etc.).</p><p><br /></p><p>Do you believe that a continuous process facility would hand calender, rather than coil/strip feed?</p><p><br /></p><p>Do you offset incrementally, index &amp; stamp your sheet then? All of the relatively high speed (i.e. Maximum ~300/min. with oscillating die for thin materials) systems I&#039;ve designed are &quot;in-line&quot;.</p><p><br /></p><p>I don&#039;t know, as I&#039;ve only designed proprietary installations, unseen elsewhere. It would seem that a continuous process should be strip fed to minimize handling problems, with infeed rolls/strips slit to width from the casting mills. This capability would generally be determined by material ductility, thickness, etc..</p><p><br /></p><p>Your facility appears optimum for variable thickness &quot;quality&quot; products, produced at a relatively low rate. That mill is a nice versatile piece of equipment.</p><p><br /></p><p>JMHO[/QUOTE]</p><p><br /></p>
