Acid electrotinning bath

Abstract: An improved acid halogen electrotinning bath composition for depositing a smooth, coherent layer of tin onto a steel substrate contains about 0.10 to 4.0 grams per liter of solution of at least one oxidation inhibiting agent comprising an organic ring compound which has a radical group such as --NH 2 or --NO 2 in the ortho or para position, for example para-aminoacetanilide and para-nitroacetanilide. Organic ring compounds, para-aminophenylacetic acid and 4-aminoantipyrine may also be added to the bath together with sodium ferrocyanide to inhibit the oxidation of the bivalent tin ions.

Titanium-bearing low-cost structural steel

Abstract: A fully killed steel has a composition of from about 0.005 to about 0.020 percent titanium and from about 0.004 to about 0.015 percent nitrogen, with the mole ratio of titanium to nitrogen being less than about 3.42. One grade of this steel exhibiting a 42 KSI minimum yield strength has from about 0.15 to about 0.27 percent carbon and from 0 to about 0.04 percent vanadium. Another grade exhibiting a 50 KSI minimum yield strength has from about 0.05 to about 0.27 percent carbon and at least about 0.02 percent vanadium. The balance of each steel is iron and other elements. Copper may optionally be provided for strength and corrosion resistance. The steel is prepared by continuous casting and hot rolling, without any quenching and tempering required to achieve the desired properties.

Impregnated fired refractory shape and method of producing same

Abstract: A HIGH-FIRED BASIC REFRACTORY SHAPE HAVING AN APPARENT POROSITY OF ABOUT 10% TO ABOUT 20%, THE OPEN PORES OF WHICH CONTAIN A SKELETAL-LIKE STRUCTURE OF A MATERIAL COMPATIBLE WITH THE HOSE MATERIAL OF THE SHAPE. FINE-GRAIN CARBON IS UNIFORMLY DISTRIBUTED ON THE SKELETAL-LIKE STRUCTURE, THE WALLS OF THE PORES AND UNIFORMLY THROUGHOUT THE SHAPE. A MAJOR PORTION OF THE OPEN PORES HAVE AN EFFECTIVE PORE DIAMETER OF ABOUT 7 MICRONS TO ABOUT 0.5 MICRON. THE SHAPE HAS INCREASED RESISTANCE TO PENETRATION AND EROSION BY SLAGS PRESENT IN STEELMAKING FURNACES AND HAS HOT CRUSHING STRENGTH EQUIVALENT TO OR BETTER THAN PREPARED CONVENTIONAL SHAPES. A CONVENTIONAL HIGH-FIRED BASIC REFRACTORY SHAPE IS IMPREGNATED WITH A SOLUTION OF A SUBSTANCE CAPABLE OF BEING TREATED TO FORM A MATERIAL COMPATIBLE WITH THE HOSE MATERIAL OF THE SHAPE. THE IMPREGNATED AND TREATED MATERIAL FORMS A SKELETAL-LIKE STRUCTURE IN THE OPEN PORES OF THE SHAPE. THE SHAPE IS IMPREGNATED A SECOND TIME WITH A CARBONACEOUS MATERIAL WHICH UPON PYROLYSIS YIELDS A FINEGRAINED CARBON WHICH IS UNIFORMLY DISTRIBUTED THROUGHOUT THE SHAPE AND UPON THE SKELETAL-LIKE FORMATION AND THE WALLS OF THE OPEN PORES IN THE SHAPE.
