摘要： PURPOSE:To permit control of the width drop to be generated at the front and rear ends of a sheet bar with good accuracy by determining the contact length between the parallel parts of dies and slab so as to minimize the width deviation of the cross rolling reduction at the longitudinal ends of a rolling stock predicted from specific conditions. CONSTITUTION:The position at the front end of the slab 3 conveyed by table rollers 4 is measured by a measuring roll 5 turning in contact with the front surface of the slab 3, a length measuring instrument 6 mounted thereto and a slab front end detector 7. The result of the measurement is inputted to a controller 8. On the other band, the shape (thickness, width) and cross rolling reduction of the slab 3 are preliminarily inputted to the controller 8. The temp. of the slab 3 is measured on the inlet side of a press by a themometer 9 and the result of the measurement is transmitted to the controller 8. The optimum length of the parallel parts of the dies and the slab is calculated from the specific conditions including the slab thickness, slab width, slab temp. and the cross rolling reduction by the press. The position of a table driving motor 10 is controlled in accordance with the result of the calculation.

摘要： A steel product having a structure composed mainly of ferrite or ferrite plus pearlite or ferrite plus cementite. A steel pipe produced from this steel product by rolling at a ferrite recrystallization temperature such that the reduction of area is greater than 20%. This steel pipe is characterized by grain size not greater than 3 mu m, preferably not greater than 1 mu m, elongation greater than 20%, tensile strength (TS : MPa) and elongation (El : %) whose product is greater than 10000, and percent ductile fracture greater than 95%, preferably 100%, measured by Charpy impact test on an actual pipe at -100 DEG C. The structure is characterized by C : 0.005-0.03%, Si : 0.01-3.0%, Mn : 0.01-2.0%, and Al : 0.001-0.10% on a weight basis, and is composed of ferrite or ferrite and a secondary phase, with ferrite grains being not greater than 3 mu m and the secondary phase having an areal ratio not more than 30%. The steel pipe is produced from a steel pipe stock having the above-mentioned composition by heating at a temperature of (Ac1 + 50 DEG C) to 400 DEG C and subsequently performing reducing on it at a rolling temperature of (Ac1 + 50 DEG C) to 400 DEG C such that the cumulative reduction of diameter is greater than 20%. The reducing is preferably performed such that at least one of rolling passes reduces the diameter by more than 6% per pass. The steel pipe will have high ductility and high strength and will be superior in toughness and stress corrosion cracking resistance, if the content of C, Si, Mn, and other alloying elements is limited low and reducing is performed at the temperature specified above. The resulting steel pipe has good fatigue resistance and is suitable for use as line pipe.

摘要： An aluminum alloy sheet which has a high level of strength and excels in formability consisting essentially of about 3 to 10 wt% of Mg and a total of about 0.3 to 2.0 wt% of Fe and Si, the aluminum alloy sheet being provided with a lubricant surface coating and having a sliding resistance of not more than about 0.11. It may also contain strengthening elements, such as Cu, Mn, Cr, Zr and Ti. The method comprises preparing an aluminum scrap containing a total of about 0.3 to 2.0 wt% of Fe and Si; melting and then adjusting the material composition so as to attain an Mg content of about 3 to 10 wt% or a composition further containing at least one of the elements Cu, Mn, Cr, Zr and Ti, each in the amount of 0.02 to 0.5 wt%; subjecting the material to casting, hot rolling, cold rolling and continuous annealing to obtain an aluminum alloy sheet having a tensile strength of about 31 kgf/mm or more; and applying a lubricant surface coating so as to impart a coefficient of friction of not more than about 0.11.
