Abstract: An apparatus for use in a continuous welding system including a welding head configured to remain stationary relative to translating steel sheets or plates. The apparatus includes a hollow elongate body and a port. The body extends between two closed ends. The port is coupled to a non-oxidizing gas source and in communication with the body. The body defines a plurality of openings. The openings are configured to direct non-oxidizing gas towards the steel sheets or plates to simultaneously shield a weld formed by the welding head from atmosphere and cool the weld.

Abstract: A continuous casting machine is provided that includes a refractory tundish funnel. The tundish funnel has a tapered shape and is designed to sit on a tundish lid in order to channel steel from the ladle to the tundish bath. A collector can also be provided to channel the steel from the ladle. The collector has an opening with a cross-section that transitions from a cylindrical shape to a cross-shape.

Abstract: Increasing the chromium content of an electrical steel substrate to a level greater than or equal to about 0.45 weight percent (wt %) produced a much improved forsterite coating having superior and more uniform coloration, thickness and adhesion. Moreover, the so-formed forsterite coating provides greater tension potentially reducing the relative importance of any secondary coating.

Abstract: A continuous coating line includes a snout assembly exposed to molten metal. The snout assembly includes a snout tip positioned about a steel strip that is immersible in the molten metal to provide a seal around the steel strip during entry into the molten metal. The snout tip includes a refractory material that is resistant to wear, abrasion, and corrosion when the snout tip is exposed to the molten metal.

Abstract: Press hardened steels exhibit increased strength in the press hardened steel parts without a corresponding decrease in elongation. Substitutional elements are included in the steel composition to increase the strength of martensite through a combination of substitutional solute strengthening and a reduction in softening that results from autotempering. Softening as a result of autotempering is minimized by suppression of the martensite start (Ms) temperature through the alloying. As a result of the increased hardenability in the proposed compositions that results from various additions of manganese, chromium, molybdenum, and niobium, the steel compositions permit a boron-free press hardening steel.

Abstract: A process for joining steel plate includes providing a steel plate and joining the steel plate to another material. The steel plate includes at least one surface having an Al—Si coating. The step of joining the steel plate to another material is performed while the steel plate is in an as- coated condition. Joining is performed using a forging process.

Abstract: A method of colorizing stainless steel strip involves the continuous surface treatment of stainless steel strip with aqueous suspensions of rare earth oxide nano or micro particles or aqueous rare earth nitrate solutions of nano or micro particles. The surface treatment can be applied by roll coating, spraying or other conventional application techniques. The coated strip is then continuously annealed. The surface treatment can provide a variety of colors. It also improves corrosion resistance of the processed stainless steel strip. Steel strip treated in this manner is suitable for a variety of applications in the building systems, automotive and appliance markets.

Abstract: A tailor-welded blank is made of two steels, one steel of Alloy A and one steel of Alloy B. Alloy A comprises 0.10-0.50 wt % C, 0.1-0.5 wt % Si, 2.0-8.0 wt % Mn, 0.0-6.0 wt % Cr, 0.0-2.0 wt % Mo, 0.0-0.15 wt % Ti, and 0.0-0.005 wt % B and wherein Alloy B comprises 0.06-0.12 wt % C, 0.1-0.25 wt % Si, 1.65-2.42 wt % Mn, 0.0-0.70 wt % Cr, 0.08-0.40 wt % Mo, 0.0-0.05 wt % V, and 0.01-0.05 wt % Ti.

Abstract: To improve oxidation and corrosion resistance of stainless steel, it is not necessary to apply suspensions containing nanoparticles of rare earth metal oxides. Rare earth metal nitrates or acetates in aqueous solution improve the oxidation and corrosion resistance of stainless steels when applied to the surface of the steels. Further oxidation and corrosion resistance can be provided by the addition of chromium or aluminum acetate, nitrate, or sulfate to the rare earth metal nitrate or acetate aqueous solutions before application to the steel.

Abstract: A weld wheel cleaning system is provided to clean or remove a layer of embedded material and other debris produced from welding from the working surface of a weld wheel. Such a weld wheel cleaning system includes a cleaner with an abrasive material positioned on an outer surface of the cleaner. The cleaner is positionable adjacent to the weld wheel such that the abrasive material is aligned with the working surface of the weld wheel. An actuator can be used to selectively actuate the cleaner with a force sufficient to remove the layer of embedded material from the working surface of the weld wheel with the abrasive material. The debris from the cleaner can be removed by a vacuum.

Abstract: A continuous coating line includes a roll assembly exposed to molten metal. The roll assembly includes a roll rotatable relative to a bearing block. The roll includes a roll portion and a journal protruding from each end of the roll portion. The roll is made from a refractory ceramic material that is resistant to wear, abrasion, and corrosion when the roll is exposed to the molten metal.

Abstract: A high strength steel comprises up to about 0.25 wt % C, up to about 2.0 wt % Si, up to about 2.0 wt % Cr, up to 14% Mn, and less than 0.5% Ni. It preferably has an Ms temperature less than 50° C. The high strength steel may have a tensile strength of at least 1000 MPa and total elongations of at least about 25% after hot rolling. It may have a tensile strength of at least 1200 MPa and total elongations of at least about 20% after hot rolling.

Abstract: A submerged entry nozzle for a continuous casting process includes a pair of triangular shaped ports that narrow from a top portion to a bottom portion of the ports. These triangular shaped ports may improve fluid flow at the discharge of the ports by increasing the velocity of the liquid steel exiting the nozzle and into the mold.
