Any expert that can help with this?

Steel superficial velocity measurement

The “Nail board method” plans to insert a steel rod of appropriate diameter in the melt. Due to the fluid velocity, the height of the free surface upstream and downstream of the sample varies. Keeping the specimen immersed for a certain period of time you can “freeze” the situation and get a “nail”. The technique allows to correlate the height difference to the velocity of the molten metal and to map the surface velocity pattern in large sections, blooms and slabs.

Thank you very much!
