PSA: I looked up the heat loss numbers for our old pouring ladles and it's worse than I thought

I was reading an old industry report from the 90s and it said our standard 500-pound ladles can lose up to 15 degrees per minute just sitting in the air before a pour. I always figured it was bad, but that's a huge chunk of heat. We've been talking about new linings, but maybe we need to look at pre-heating the ladles more, or even those insulated covers I used to think were a waste of time. Has anyone tried those covers on a production floor and did they actually help?

Oh man, that's wild! We did the same thing with some custom covers and it was a total game changer. Honestly made the whole pour way more consistent.

We had the same problem with our smaller ladles. Boss got some ceramic fiber blankets and we made our own covers. Cut the drop down to maybe 5 degrees a minute. Big difference in pour temp. Pre-heating helped too, but those covers were the real fix. Cheap and easy to do.
