  • Thermomechanically controlled processed high strength weathering steel with low yield/tensile ratio
    Patent number: 6056833
    Abstract: A high performance weathering steel having a minimum yield strength of 70-75 ksi and a yield/tensile ratio less than about 0.85 is produced from a steel composition consisting essentially, in weight percent, of about: carbon 0.08-0.12%; manganese 0.80-1.35%; silicon 0.30-0.65%; molybdenum 0.08-0.35%; vanadium 0.06-0.14%; copper 0.20-0.40%; nickel 0.50% max.; chromium 0.30-0.70%; phosphorous 0.010-0.020%; columbium up to about 0.04%, titanium up to 0.02%, sulfur up to 0.01%, iron, balance except for incidental impurities; heating the steel to a hot rolling temperature, rolling the steel to a thickness about 2 to 3 times the final desired thickness, air-cooling the steel to a temperature of about 1800-1850.degree. F. (RCR) or about 1600-1650.degree. F. (CCR), recrystallize control rolling or conventionally control rolling the steel with finish rolling at a temperature of about 1700-1750.degree. F. (RCR) or about 1400-1500.degree. F. (CCR), then water-cooling the steel to about 900-1200.degree. F.

  • Method of restoring ingot mold stools and closed-bottom ingot mold
    Patent number: 4005742
    Abstract: A method of repairing large castings, such as ingot molds and mold stools, by employing an aluminothermic reduction reaction without using containment perimeters and without preheating the casting. The resultant repaired article has a metallurgically bonded plug in the hole or eroded surface with a thick abrasion-resistant slag covering over the deposited metal.
    Type: Grant
    Filed: March 8, 1976
    Date of Patent: February 1, 1977
    Assignee: United States Steel Corporation

  • Method of repairing large castings
    Patent number: 3942578
    Abstract: A method of repairing large castings, such as ingot molds and mold stools, by employing an aluminothermic reduction reaction. The resultant repaired article has a metallurgically bonded plug in the crack, hole, break, or eroded surface. An alternative repair method of big-end-up ingot molds is disclosed which comprises forming a ceramic lining on the bottom of the mold.
