Our rolling mill (roughing mill, really) has a persistent problem with turn up on tool steel plate. Does anyone have any experience or suggestions with correcting this? Until recently I've been an aluminum metallurgist, and this is my first rolling problem with steel plate.

Hey all,
Our hot mill has been having trouble getting consistent yield and tensile values between the heads and tails of Ti grade HSLAs. To say it a little differently, the head of the coil will exhibit different mechanical properties than the tail, resulting in some of the coil meeting the...
At what approximate temperature and how long will that take? We've been having big issues with heat pattern scale formation on these grades and I'm having trouble narrowing down the window of which to investigate.

Andrew,
Thanks so much for your suggestions, insight, and information. I decided to do some reading and ask a few questions around here before I responded back to you. I think its pretty well known that the coiling temperature would affect the scale build up (and we think the heat pattern...
Thank you, that's gonna be the first thing I check. Hopefully all it will take is to spread those coils out in the first stage of cooling.

We're having a ton of HPS buildup on these grades coming out of our hot mill and into the pickle line in the cold mill, and we don't really know why. One idea floating around is heat retention between the coils when they're sat in groups to coil... anyone have any insight on the validity of...
