How do I remove Chromium Carbide from the finished product?

How do I remove Chromium Carbide from the finished product?

How do I remove Chromium Carbide from the finished product?

(OP)
We are having trouble with the VRN 400 and 500 liners we are currently using on a Silicon Carbide producing plant. Some of the VRN 400 liners in the crusher last about seven hours before they need to be replaced.

I want to test Chromium Carbide liners, as they rate it to last 8-12 times longer than VRN400, to see how it compares. At the moment we remove the steel from the finished product magnetically before it gets packed. I don't want to re-invent the wheel to be able to get a "clean" product at the end.

So my question is, will I be able to remove the chromium from the product magnetically and if not, what would be a suitable (affordable) replacement for VRN?

I don't know, why don't you look us Chrome carbide and see if it is magnetic?
But first you need to know which carbide it is, M23C6? or one of the others.

From the hardness given it relates to Cr23C6.

I did look it up, but can get any definite answers. I know Chrome gets funny with its magnetic properties at different temperatures and as it isn't pure chrome in the composition I don't want to make any assumptions.

Is there a binder phase used in this coating? That might be easier to separate.
I would expect chrome carbides to be weakly ferromagnetic (similar to Cr oxide), probably too weak to be useful to you.
If this is being done by spray (arc or flame) there is probably a binder added, and the carbide is likely 2:3, or maybe 7:3, 23:6 is the softest of the three.
