    Those first passes must be compressing the square corners in such a
    way that fins are being forced into the body of the wire. Try filing
    off the sharp corners so that the cross section of the wire is closer
    to the shape of the roller, then proceed in compressing the wire,
    carefully and slowly, as usual. 

    When making wire with a rolling mill, as you roll the square wire
    down, each pass is made two times at 90 degrees to each other. If you
    go down too fast and get a fin, that fin gets rolled over and is not
    evident until you start drawing the square wire though the drawplate.
