摘要： An aluminum alloy sheet for motor vehicles is produced by casting a melt, containing 3.0-3.5 mass % Mg, 0.05-0.3 mass % Fe, 0.05-0.15 mass % Si, and less than 0.1 mass % Mn, a balance substantially being inevitable impurities and Al, into a slab having a thickness of 5 to 15 mm in a twin-belt caster so that cooling rate at ¼ depth of thickness of the slab is 20 to 200° C./sec; winding the cast thin slab into a coiled thin slab subjected to cold rolling with a roll having a surface roughness of 0.2 to 0.7 μm Ra at a cold rolling reduction of 50 to 98%; subjecting the cold rolled sheet to final annealing either continuously in a CAL at a holding temperature of 400 to 520° C. within 5 minutes or in a batch annealing furnace at a holding temperature of 300 to 400° C. for 1 to 8 hours; and subjecting the resulting sheet to straightening with a leveler.

摘要： A controlling member (a controlling pin 10) is inserted through an insertion hole 7 of a mold 1 and projected into a cavity 6. After a pipe P as an insert member is arranged at a predetermined position in the cavity 6, the pipe P is held in the cavity 6 by inserting a tip of the controlling pin 10 into a hole h of the pipe P at the end p1, or by inserting the end p1 of the pipe P into a cave 21 of the controlling member. A molten aluminum alloy is then poured through a gate 5 into the cavity 6 under such the condition, to enclose the pipe P with the aluminum alloy. Dislocation of the pipe P caused by kinetic and thermal energies of the poured aluminum alloy is suppressed by the controlling pin 10 or block 20 at the end p1. Since the enclosed pipe P has its end p1 opened at a predetermined position, a cast product obtained in this way can be used as a brake caliper or the like having an inner hydraulic circuit.
摘要翻译：控制构件（控制销10）通过模具1的插入孔7插入并突出到空腔6中。在作为插入构件的管P布置在空腔6中的预定位置之后，管P是通过将控制销10的尖端插入端部p1处的管P的孔h中，或者将管P的端部p1插入到控制构件的洞穴21中而保持在空腔6中。然后在这种条件下，将熔融的铝合金通过浇口5浇注到空腔6中，以用铝合金包住管道P. 通过浇注铝合金的动能和热能引起的管道P的位移由端部p1处的控制销10或块20抑制。由于封闭管P的端部p1在预定位置处开口，所以以这种方式获得的铸造产品可以用作具有内部液压回路的制动钳等。

摘要： The newly proposed cast aluminum alloy product has the composition consisting of 6.5-8.0% Si, 0.25-0.45% Mg, 0.08-0.40% Fe, 0.001-0.01% Ca, P less than 0.001%, 0.02-0.1% Ti, 0.001-0.01% B, optionally one or two of 0.05-0.3% Cr and 0.05-0.2% Mn, and the balance being Al except inevitable impurities. It has the metallurgical structure that an null-Al phase in a surface layer is of average grain size different by 50 nullm or less from an null-Al phase in an inner part, and that a maximum size of eutectic Si particles is 400 nullm or smaller. It is manufactured by injecting a molten aluminum alloy into metal dies at an injection speed of 0.05-0.25 m/second, and then cooling the injected alloy at a cooling speed of 20null C./or higher in a temperature range between liquidus and solidus curves in a state charged with a pressure of 30 MPa or higher. Since the cast product is good of ductility, it is used as a member for coupling another member therewith by calking or the like.

摘要： A web conveying method and apparatus in which a metal web is maintained substantially parallel to an adjacent electrode despite fluctuations in the flow of an electrolytic solution in which the web is immersed. A guide plate is disposed adjacent the web on the side thereof opposite the electrode. A plurality of through-holes are formed in the guide plate which are evenly distributed thereon. Due to the flow of solution through the guide plate, a static pressure is applied to the web which maintains it substantially parallel at all times to the electrode.
