High temp/header paint for use in steel mill
High temp/header paint for use in steel mill
(OP)
I work in a steel mill, and we have some off-spec ingot molds that we need to identify. We still want to use the molds, but due to a manufacturing error on the part of our supplier, our standard hot-top boards don't fit.
We want to paint the molds (or part of the molds) with some sort of high temperature paint, to clearly distinguish the off-size molds from the standard molds. A google search brought up the standard grill paint, but I think this won't suffice. After further investigation, I found "header paint" for exahaust headers. Would this be sufficient for our application?
The molds are cast iron, and some sections reach very high temperatures after teeming (glowing cherry red). There are other parts that don't see temperatures this extreme, and we will probably apply the paint there.
I figured I'd ask the experts here before I recommend this to my boss, in case it fails. Thanks in advance.

A good idea, but it probably wouldn't work for our shop.

Put 'em through a PVD or anodize process, maybe? I envision the problem of residual moisture in an ingot mold to be a bad one, so you'd might need to chemically modify the outer layer of metal rather than cover it up with another layer.

We've decided to try the header paint, as further investigation has shown it to be fairly cheap and simple to apply in-house, and should last for our application. After shooting the molds in use, the hottest section was right around 1200F. The area we're thinking of painting was only around 800F. Plus, the paint offers us a variety of colors, so we can pick a color that will be readily identifiable in all lighting conditions, indoors or outdoors, day or night. If anyone's interested, I'll post how the trials go.
