My ladle pre-heat trick fixed our cold shut issues
Honestly, we were struggling with cold shuts in our iron castings for weeks. Tbh, it was causing a lot of scrap and slowing down production. I noticed the metal was cooling too fast during the pour, so I started pre-heating the ladle before each use. Ngl, it took a bit of extra time, but the castings came out much better. Last batch, we had zero defects after I made this change. Has anyone else tried this? I'm curious if other foundries have similar fixes.
