  • Patent number: 7614463
    Abstract: A flute-wiping auger cleaner has a laterally-shearing shackle, an axial track spaced parallel to the auger; and a traveling carriage on the track for supporting the shackle. The shackle includes a series of angularly-staged wiper blades to project into the flute of the auger and centrally stabilize the blades on the turning axis of the auger. The shackle is biased not only to pressure the wipers inwards towards the auger's cylindrical sidewall but also allow the shackle to open slightly against the force of the bias in event a blade cannot dislodge a difficult clump of fouling material in the flute. In that event, the blade is pushed out and then pressured back in as it rides over the difficult-to-dislodge clump. Spinning the auger causes the blades to travel the length of the helical flute while the shackle travels axially on the track.

  • Publication number: 20010022156
    Abstract: An apparatus installed in a molten metal plating line includes a blade pressed against a roll dipped in a molten metal plating bath, in which a metal strip travels. The apparatus removes substances deposited on a surface of the roll. The apparatus also includes an arm for supporting the blade, and a screw member disposed above the plating bath so as to traverse it and moving along an axis of the roll in the bath for removing substances deposited on the roll in the molten metal plating bath. Floats and/or weights are mounted on the arm so as to adjust a press force of the blade applied to the roll in the molten metal plating bath. A method for preventing the occurrence of dents on a molten-metal-plated steel strip using the apparatus is also disclosed.
