    • PURPOSE: A method of manufacturing aluminum alloy with a groove unit and a protruded undercut is provided to strongly maintain the bonding state of an aluminum alloy material and a resin material since an aluminum alloy structure covered with a fine groove unit and a protrusion unit is put into a mold and then resin composition is insert-injected. CONSTITUTION: A method of manufacturing aluminum alloy with a groove unit and a protruded undercut comprises next steps. Aluminum alloy is shaped by die casting or mechanical processing. Oil components adhered from the shaping process are removed using surfactant. The oil-removed aluminum alloy is immersed in alkali solution of 10~100 g/l. Foreign materials and an aluminum oxide film are removed from the immersion process, and the surface activated aluminum alloy is etched by acid solution of 100~300 ml/l, which is selected from hydrochloric acid, sulfuric acid, and nitric acid.
    • 目的:提供一种制造具有凹槽单元和突出底切的铝合金的方法,以强烈地保持铝合金材料和树脂材料的粘合状态,因为放置有细槽单元和突出单元的铝合金结构 进入模具,然后插入树脂组合物。 构成:制造具有凹槽单元和突出底切的铝合金的方法包括以下步骤。 铝合金通过压铸或机械加工成型。 使用表面活性剂除去从成型过程粘附的油组分。 除油铝合金浸入10〜100 g / l的碱溶液中。 从浸渍工艺中除去异物和氧化铝膜,用盐酸,硫酸和硝酸选择100〜300ml / l的酸溶液蚀刻表面活性铝合金。

    • PURPOSE: A low carbon-metal manganese and a low carbon-ferromanganese manufacturing method by using continuous thermal reaction are provided to manufacture low carbon ferromanganese without a separate process using waste in an aluminum melting furnace as a reducing agent. CONSTITUTION: A low carbon-metal manganese and a low carbon-ferromanganese manufacturing method comprises next steps. Scrap iron, a metal manganese or ferromanganese is put in an electric furnace in order to manufacture a molten metal. The ore briquette is put in the molten metal and the metal mesh manganeseor the ferromanganese molten metal in order to make thermale reaction. The slag is removed by thermale reaction. The content of the Mn of the manganese mineral powder or the manganese dust is 30 weight%.
    • 目的:提供使用连续热反应的低碳金属锰和低碳 - 锰铁制造方法,在铝熔化炉作为还原剂的情况下,不用单独的方法制造低碳锰铁。 构成:低碳金属锰和低碳锰铁制造方法包括以下步骤。 将废铁,金属锰或锰铁放入电炉中以制造熔融金属。 将矿石块放入熔融金属和金属网锰或锰铁熔融金属中,以进行热成型反应。 炉渣通过热反应除去。 锰矿粉末或锰粉的Mn含量为30重量%。
