[QUOTE="Sda36, post: 337187, member: 17701"] Thanks Patrick, could you expand a bit more on conservative cooling cycles for Zr? All I've heard for years is that "you Can't slow cool enough." Or over-slow cool. I have presently on my Zubler furnaces a cool rate of 25-40 degrees / min and an opening temp of 250 degrees C that matches my Zubler sintering oven for opening temperature. ( Depending on structure and size) This makes for some Really Long Cycle times. Are you really comfortable, across the board with a near 500 degree Celsius opening temp.? I realize you can also extend cooling by having a 10 minute opening time at least on my Zubler furnaces. Looking forward to your thoughts on this, it's a big thing given an Emax cycle being typically 25 min or less. Thanks for your time and input Patrick! [/QUOTE]
