Creating company logo on hot-rolled steel bars

2006

Dear all,
Our goal is to create a company logo on hot-rolled steel bars. We consider some types of inkjet printers, but the problem is that the steel bars have a temperature of 500-600 °F (250-300 °C), at the point in production line that is convenient to print. We are told that there is no type of ink that can be put on such hot steel. Therefore, we are trying to find other ways of creating our logo on the hot steel bars, e.g., by surface corrosion techniques.
Any help that you can give us is of great importance.
Thank you,

Ilias Bekiros

Either Electro Discharge Machining (EDM), machine tool engraving or chemical etching may be used depending on complexity of your logo, desired depth and available process may be used.

Years ago, working in a steel mill, casting billets, we needed a way to mark billets at 300-600C with cast number.
The simple solution is a wax crayon of light green colour. The wax burns leaving an almost white image behind.

Sounds like you have some volume to work with... Look into having a tool-steel punch made and a small press to knock an impression into the bar. This type of thing can be made to move with the part as it strikes so that no "wiping" occurs and the line never has to stop.

These punches are not as expensive as they used to be... Check it out.
