  • Patent number: 10041140
    Abstract: Disclosed is a method for continuous thermal treatment of a steel strip. The strip passes through consecutive thermal treatment chambers, is quickly cooled in at least one of the chambers by spraying liquid onto the strip, or by spraying a fluid made up of gas and liquid or spraying a combination of gas and liquid forming a mist. After quick cooling, a protective metal layer is deposited on the strip by dip coating. The cooling fluid strips iron oxides or other alloy elements contained in the steel to be treated, minimizing oxidation and reducing the oxides on the strip. Spray pressure and distance are chosen to facilitate the stripping property and the mechanical action of the sprayed fluid, reducing the layer of oxides on the strip. The temperature of the strip at the end of the cooling step is the temperature necessary for carrying out the desired treatment cycle.

  • Patent number: 7625439
    Abstract: The ferrous metal chemical conversion coating is comprised of mixed oxides and organometallic compounds of aluminum and iron. A ferrous metal substrate is immersed for a period of time in a bath composition, at a temperature, at a pH, and at a concentration for each constituent of the bath composition, that will form a coating with the desired characteristics. The bath composition comprises water, aluminum salt, oxalic acid, and an oxidizer. The conversion coating is amorphous in nature and can be formed as thin as 1 micron with a coating weight in the range of about 40-250 milligrams per square foot. When sealed with an appropriate rust preventive material, the coating enhances corrosion resistance of the ferrous metal substrate. It is an effective absorbent base for paint finishes. When top coated with a lubricant, the conversion coating aids (a) assembly of parts, (b) break-in of sliding surfaces, and (c) anti-galling.

  • Patent number: 7476445
    Abstract: It is an object of the present invention to provide an organic coating-treated metal sheet, having a coat capable of satisfying all the corrosion resistance, alkali resistance, solvent resistance, anti-scratch property and adhesion requirements which the conventional nonchromate type coating technologies have been difficult to meet. A surface-treated metal sheet with a coat comprising 50; to 90% by weight of a crosslinked resin matrix (A) and 10 to 50% by weight of an inorganic rust preventive (B) as formed on the metal sheet surface, wherein the crosslinked resin matrix (A) is formed by the reaction between a water-borne resin and a crosslinking agent and has an acid value of 0 to 30 due to carboxylic acid groups not neutralized by an alkali metal and a hydroxyl value of 5 to 50.
