Hi People. Please, I need to know which is the best material to make the guideline plate in a hot rolling grinding ball machine.
Here the is a link to see the process:

If you want you can see the upper part (guideline plate) at 0:42 of the film.
The process and the product are in the figures attach.
Thanks in advance.
Material selection depends on the temperature seen by the guide plate in service, and other criteria such as cost, wear and accuracy. Unless you specify these criteria you will not receive anything other than general comments (or nothing at all).
Tool steels that are used in hot forging dies may be an option to consider, but to arrive at a definitive selection you need to specify many more parameters.
Dear Sir. This is all the information that I have:
This guideline plate is used for making 38,1mm diameter milling ball.
The production is 1000 kg/h. The temperature of the bar is 850 °C.
The material is SAE 1082 steel.
Many thanks.
Many thanks Dr. Levers.
This material have excellent temperature resistance, but what about the wear resistance at high temperature?
I think, given the data on the .pdf, wear resistance will be a design parameter for the materials.
You will need to speak with the manufacturers directly to obtain more detailed property data, particularly hot hardness which will give you a good comparison between difference materials with respect to their ability to resist wear.
