摘要： A molten metal vessel includes a first chamber for containing molten metal such as molten aluminum therein, a filtration chamber in which impurities contained in the molten metal are removed, and a second chamber for reserving clean molten metal to be supplied to a casting die. The molten metal flows from the first chamber to the second chamber through the filtration chamber. A pair of filters, preferably a pair of cylindrical filters, are disposed in the filtration chamber, so that the impurities contained in the molten metal can be filtered twice. The filters are attached to the bottom of the filtration chamber where molten metal oxides hardly develop, so that the filters are easily replaced with new ones for the maintenance purpose. A rod-shaped heater may be disposed in the cylindrical filters to keep the molten metal temperature in a strictly controlled range. Thus, the impurities are effectively removed from the molten metal through the filters which are easily replaceable.
摘要翻译：熔融金属容器包括用于容纳熔融金属的熔融金属的第一室，其中除去熔融金属中包含的杂质的过滤室，以及用于保存供给铸模的清洁熔融金属的第二室。熔融金属通过过滤室从第一室流向第二室。一对过滤器，优选一对圆柱形过滤器，设置在过滤室中，使得包含在熔融金属中的杂质可以被过滤两次。过滤器附着在过滤室的底部，其中熔融金属氧化物几乎不形成，从而为了维护目的，过滤器容易被更换。柱形加热器可以设置在圆柱形过滤器中，以使熔融金属温度保持在严格控制的范围内。因此，通过易于更换的过滤器，有效地从熔融金属中除去杂质。

摘要： A die-casting method that eliminates the need to inject insulation. By injecting molten metal sufficiently quickly after injecting tip lubricant, die-cast products may be removed from the mold even without injecting isulation. To this end, a movable die may at least begin moving toward a fixed die before tip lubricant is injected. The tip lubricant may be injected from a molten metal pouring port in a shot sleeve or from the movable die toward the shot sleeve. Tip lubricant which has been introduced into the shot sleeve is conveyed into the die cavity by movement of the molten metal, thus coating the die cavity inner surface.
摘要翻译：一种压铸方法，无需注入绝缘。在注射尖端润滑剂之后，通过充分快速地注入熔融金属，即使不注射成型，也可以从模具中除去压铸产品。为此，在注入尖端润滑剂之前，可移动模具可至少开始朝向固定模具移动。尖端润滑剂可以从喷射套筒中的熔融金属浇注口或从活动模具朝向喷射套筒喷射。通过熔融金属的移动将引入到喷射套筒中的尖端润滑剂输送到模腔中，从而涂覆模腔内表面。

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 α-Al phase in a surface layer is of average grain size different by 50 μm or less from an α-Al phase in an inner part, and that a maximum size of eutectic Si particles is 400 μm 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 20° 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 holding furnace apparatus for holding molten metal and a molten metal holding method using the same are provided. The holding furnace includes generally a furnace body defining therein a reservoir chamber in which molten metal is held, an inlet port through which an ingot is supplied, an outlet port through which the molten metal held in the reservoir chamber is drawn outside, and an upper furnace wall defining the reservoir chamber together with the furnace body. The upper furnace wall has an inclined wall surface which is, when the reservoir chamber is filled with the molten metal at a given level, exposed to the molten metal so as to direct impurities contained in the molten metal rising to the surface of the molten metal to the inlet port.
