摘要： Methods of producing high strength continuously cast hot rolled steel sheet products are disclosed. The methods include continuously casting a steel slab and then hot rolling with finish rolling on a hot strip mill, quenching on the hot strip mill to form a predominantly matrensitic microstructure, and performing a thermal cycling step including soaking at an intercritical temperature followed by holding at a lower temperature. The resultant hot rolled steel sheet products have a microstructure comprising ferrite and retained austenite. Steels processed in accordance with the present invention exhibit favorable combined ultimate tensile strength and total elongation (UTS·TE) properties, and may fall into the category of Generation 3 advanced high strength steels, desirable in various industries including automobile manufacturers.

摘要： A method to improve the collapse resistance of metallic tubular products is disclosed. Stress is applied to the metallic tubular products in order to change the residual stress profile of the metallic tubular products, such as those that have completed a straightening process, resulting in a residual stress profile that improves collapse resistance. The metallic tubular product is subjected to radial compression processing to control the residual stress profile and to enhance collapse resistance. The radial compression process may be applied after the tubular product has been subjected to a straightening process.

摘要： A fuel injection lance for an ore-smelting furnace includes a central conduit, a first conduit and a second conduit. The first and second conduits are concentric with the central conduit. A central conduit is connected to a fuel mixture. The first and second conduits are in flow communication with a gas source. The first and second conduits have gas flowing at independently controllable gas flow rates relative to the other conduit. A swirl portion has a cylindrical body with a hollow interior cylinder, and vertical and helical channels formed within the body portion. Vertical channels traverse the body portion vertically to the outer surface adjacent to the bottom surface. Helical channels traverse the outer surface in a helical pattern. Vertical channels intersect with corresponding helical channels at a predetermined angle selected to provide a desired particle distribution of a fuel injected into the furnace.

摘要： A method is disclosed for scraping a roll surface rotating in a molten metal coating process comprising traversing a support assembly to one side, lifting the arms attached to said the assembly to a fully retracted position to disengage scraper blades from contact with a roll surface; initiating a scrape cycle by means of a trigger signal; lowering the arms and scraper blades in the mid-point of the sink roll; increasing the pressure reference from lifting pressure to approximately zero; energizing one or more directional valves; increasing the pressure value gradually to a preselected pressure; extending the cylinder in a controlled manner to engage the scraper head gently on to the sink roll; moving the engaged scraping head at controlled, predetermined speed from the sink roll mid point to the fully traversed out position; stopping the traversing means upon reaching the fully traversed out portion; and lifting the scraper head from the roll surface by removing pressure from the cylinder; then repeating the sequence until a predetermined number of cycles are completed.

摘要： An apparatus for scraping the surface of a sink roll in a molten metal coating process comprises a support member having a pair of linearly movable arms supported thereon. The support member depends from a bridge structure spanning a continuous metal coating line, and a pair or arms, the arms being disposed on opposite sides of said support member. Each arm has a scraper assembly portion attached thereto. Each scraper assembly portion has two blades affixed thereto, a forward scraper blade and a rear scraper blade, with a connecting portion connecting the two blades. The connecting portion also has a first pivot point for attaching the connecting portion to the arm associated with the scraper assembly portion, the first pivot point being disposed between said forward and rear scraper blades for following the radial contours of the roll surface. A second pivot point permits the blades to follow the crown of the roll. Pneumatic cylinders advance the arms such that at least one scraper blade presses against the roll surface under pressure. There is also control means for controlling the pressure of the scraping force of said blades applied to the roll surface. A traversing means provides for communicating lateral movement of said blades laterally along the axis of the roll while scraping against the roll.
