    • PURPOSE: An aluminum alloy material for foaming is provided which is inexpensively manufactured using waste aluminum and aluminum alloy scrap, obtains uniformed pore size and distribution by increasing viscosity and strength of aluminum alloy and obtains superior physical properties, and a method for manufacturing the same is provided. CONSTITUTION: The method for manufacturing an aluminum alloy material for foaming comprises the step (a) of preparing aluminum alloy powder for foaming using centrifugal atomization; the step (b) of preparing mixed powder with a stone mill mixer by mixing additive powder and foaming agent powder with the powder of the step (a); the step (c) of preparing mixed powder green by compressing the mixed powder of the step (b) using a compressor; and the step (d) of hot extruding the mixed powder green of the step (c), wherein the centrifugal atomization is carried out to manufacture rapid solidified acicular aluminum alloy powder having a size of 80 to 700 micrometers by charging molten aluminum into a tundish and flowing out the molten aluminum to the lower side through a nozzle at the lower part of the tundish so that the molten aluminum is dropped onto the center of a flat rotor installed under the nozzle, thereby centrifugally dispersing the molten aluminum.
    • 目的:提供一种用于发泡的铝合金材料,其使用废铝和铝合金废料廉价制造,通过增加铝合金的粘度和强度获得均匀的孔径和分布,并获得优异的物理性能,并且其制造方法 提供。 构成:用于制造用于发泡的铝合金材料的方法包括:使用离心雾化制备用于发泡的铝合金粉末的步骤(a); 通过将添加剂粉末和发泡剂粉末与步骤(a)的粉末混合,用石磨混合机制备混合粉末的步骤(b); 通过使用压缩机压缩步骤(b)的混合粉末来制备混合粉末绿的步骤(c); 和步骤(c)的热挤压步骤(d),其中进行离心雾化以通过将熔融铝装入中间包来制造尺寸为80至700微米的快速凝固的针状铝合金粉末 并且通过中间包下部的喷嘴将熔融铝流出到下侧,使得熔融铝落在安装在喷嘴下方的平转子的中心,从而离心分散熔融铝。

    • PURPOSE: A safe support is provided to spread a part of a handrail by sensing a child who climbs up on a handrail, thereby accepting the falling child. CONSTITUTION: A safe support comprises a horizontal support(50), an upmost horizontal rod(60), a vertical support(30), a support bar(40), a rotary safe rod(20), a joint bolt, and a latching fixing large(10). Both ends of the horizontal support are horizontally fixed at both sides. Both sides of the upmost horizontal rod are fixed on the top of the horizontal support. The vertical support is fixed at the lower end of the horizontal support and is vertically fixed on the bottom of the balcony floor. One end of the support bar is fixed to the horizontal support and the vertical support, and the other end is extended to the lower part. The rotary safe rod is fixed on the top of a rotary shaft(24). The joint bolt comprises a cut groove. The latching fixing part includes a support ring.
