摘要： A process of consistenly producing in an economical manner a galavanized steel strip having on one side a thin uniform surface coating of zinc-iron intermetallic compounds containing at least 6 percent iron and being free of metallic zinc and having on the other side a formable metallic zinc surface coating which is formed by continuously immersing the steel strip in a hot-dip zinc coating bath in which the temperature of the steel strip and the coating bath are controlled within a limited range to avoid forming an exclusively thick zinc-iron intermetallic layer during hot-dip coating which interferes with good formadibility of the metallic zinc surface coating and controlling the thickness and uniformity of the zinc coating which is transformed into the coating formed of zinc-iron intermetallic compounds within a range of 10 to 30 g/m2 while maintaining the variation in coating weight within a range of from 3 to 6 g/m2 and heating the strip rapidly to a peak temperature of between about 482 C and 524 C within a period of 3 to 5 seconds and allowing the strip to cool below the melting point of the zinc coating.

摘要： A novel high strength steel especially adapted for automotive applications and the like is provided by cold rolling a low carbon aluminum-killed steel containing added phosphorus and silicon as ferrite strengtheners, continuously heating the cold rolled strip to an inter-critical temperature such that from about 5% to about 25% austenite is present, water quenching to obtain a dual phase ferrite-martensite microstructure having an average volume fraction of martensite of from about 5% to about 25%, and reheating to a sub-critical temperature to temper the steel. The resultant steel has good formability as evidenced by a minimum total elongation of 18%, is free from ductility loss due to room temperature aging, and after stamping followed by a typical paint bake cycle the formed part has a minimum yield strength of 550 MPa (80 ksi).

摘要： PROBLEM TO BE SOLVED: To eliminate the need for an in-bath guide roll and to prevent the leakage of a hot dip plating metal from an opening by passing a strip upward from the bottom opening of a vessel for holding the bath of the hot dip plating metal and impressing a magnetic field thereon by an electromagnetic arranged along an outside wall. SOLUTION: The bath 40 of the hot dip plating metal is held in the vessel 38 consisting of a trough-like wide upper art and a narrow lower part. The steel strip 32 introduced from the aperture 43 in the bottom converging toward the lower part is passed upward in the bath 40 and is taken out. The plated steel strip 31 is obtd. by regulating the plating weight with air knives 44, 44. The electromagnet 50 having a magnetic pole member 108 along the outside wall is arranged on the outside of the vessel 38 of such hot dip plating system 30 and the magnetic field is impressed on the bath 40 via the nonmagnetic outside wall. Eddy current is generated in the bath 40 by the magnetic field, by which the hot dip plating metal is fluidized upward and is confined within the vessel 38. The leaking and dripping of the metal from the aperture 43 are prevented.

摘要： PURPOSE: To prevent leakage of a molten metal from an opening edge of a space vertically extending between two rolls horizontally arranged at a space. CONSTITUTION: An electromagnetically confining device prevents leakage of the molten metal via the opening edge 36 of the vertically extending space 35 between two rolls 31, 32 turning reversely to each other in a device for continuously casting plates 37. The molten metal is located between rolls 31, 32. The device has a vertically arranged coil 40 and a first horizontal magnetic field is generated near the opening edge 36 of the space 35 by flow of current changing with the lapse of time in the coil 40. Conduction current changing with the lapse of time flows via a pool 38 of the molten metal near the opening edge of the space and flows toward a vertical direction 64 opposite to current flowing near a coil section 41. The conduction current via the molten metal pool 38 generates a second horizontal magnetic field near the opening edge 36 of the space 35, intenifies the first horizontal magnetic field and supplies repulsive pressure pushing back the molten metal pool 38 to inside from the opening edge 36 of the space 35.

摘要： PURPOSE: To prevent the outflow of molten metal from the open end of a gap formed between two members parted in a horizontal direction with a continuous molten metal casting system for allowing the molten metal to flow out of the gap and executing the casting. CONSTITUTION: The outflow of the molten metal from the open end 26 is prevented by a magnetical confining device 200 in the continuous molten metal casting system for allowing the molten metal to flow out of the gap 25 formed in a perpendicular direction from the two rolls 21 and 22 parted from each other in the horizontal direction. The device 20 has a conductive coil 30 for generating the magnetic field in the horizontal and nonmagnetic fins for concentrating current on the surface of the coil nearest the open end of the gap 25. The magnetic field induced by the device 20 extends through the open end 26 of the gap 25 and makes a confining pressure acts on the molten metal in the gap 25.

摘要： PURPOSE: To predict the possibility of break-out of molten metal by paying attension to the vertical distance between a peak temp. location and a molten metal level position, further continuously monitoring this vertical distance and using a step for detecting all the states in the case of causing the increase therein. CONSTITUTION: The molten metal 40 is formed into a cast metal shell 42 lowered through a wall surface, upper end part 21, opening lower end part 22 and liquid cooling mold 20 vertically set. In the relation with the upper end of the mold 20, the position of the molten metal 40 level in the mold 20 is continuously measured and also, the location of the peak temp. in the mold is continuously measured. By paying attension to the vertical distance between the peak temp. location and the molten metal 40 level position, further, this vertical distance is continuously monitored and the step for detecting all the states in the case of causing the increase therein is adopted. In this way, the characteristic defect and the problem point in the method of preceding technique for predicting the possibility of break-out of the molten metal can be dissolved.

摘要： PURPOSE: To provide a side wall confining apparatus for molten metal by horizontal alternating magnetic fields of a low cost which facilitates the cooling of roll rims and has the excellent electromagnetic confining performance of the molten metal existing between rolls without the excess heat loss in the rolls and magnetic poles. CONSTITUTION: The leakage of the molten metal 12 in the gap of the two counter-rotating rolls 10a and 10b of a continuous strip-casting apparatus from the open side of the gap is prevented by the confining apparatus. This apparatus generates the horizontal magnetic field spreading through the open side of the gap. The apparatus includes the structure for substantially confining the magnetic field to the open side of the gap and for preventing the dissipation of the magnetic field from the open side of the gap.

摘要： PURPOSE: To electromagnetically meter molten metal stream flowing in a tubular passage by energizing a primary coil wound on the tubular passage. CONSTITUTION: A primary coil 23 is composed of a hollow rectangular copper wire, and cooling water is passed through the inner part of this wire to keep the coil 23 in the allowable temp. range. This coil 23 is surrounded with a magnetic material 24 and furthermore, a ferritite cylinder 25 surrounds a refractory funnel and tube 21, and a refractory heat insulating material 22 at the low end part of the coil 23. Then, the current composed of AC and DC is supplied to the primary coil 23, so that the frequency of AC optimizes the ratio of magnetic pressure/electric power loss. In this way, a magnetic field pattern is formed and the variation in the magnetic field intensity at the lower end of the primary coil 23 is generated, so that molten metal stream can be metered.
