Switched from a standard 2-inch riser to a 4-inch on our main pour line last month

The extra height gave us way better slag control and cut our scrap rate by almost 15%. Anyone else find a simple change that made a huge difference in your pour quality?

Read an article a while back about how the perfect riser height isn't a set number. It's more about matching the metal flow to your specific line speed and mold design. Makes you wonder how many shops are just copying what the guy before them did without checking if it's right for their own gear. Your results and Noah's show both sides of that coin pretty clearly. Guess the real trick is having the time and will to actually test things out.

Huh, that's a solid result. We had the opposite problem on one of our older lines. The higher riser just made the stream break up more, caused more turbulence in the mold. We actually went back down an inch and slowed the pour speed a bit. Fixed it completely. Sometimes the simple fix is just finding what actually works for your specific setup.

Our old foreman swore taller risers were always better. Watching your line handle the change so well made me realize he was just stuck in his ways. Sometimes the equipment knows more than the guy who bought it.
