    It could be that your rollers produce a square bar with sharp
    corners, or corners with small bevels or radii. My Cavallin rolling
    mill produces a square bar with large bevels on the corners; the bars
    can go directly to the drawplate without any problem. 

    Flashing can happen in my mill but I have to push it... what I do is
    pass once, screw the roller down, rotate the bar and pass again; ie I
    do not have to pass twice before screwing down except with the
    largest groove (5mm to 4mm). 

    A mill with sharp-cornered grooves needs extra care in rolling to
    prevent flashing, and the sharp corners must be removed from the bar
    before it goes to the drawplate.
