摘要

回收是一种处理废旧材料的方式,从选择、收集开始,然后是铸造过程,以创造更有价值、更经济的新产品。本研究的目的是了解以闸瓦和盘为导向材料的AI合金渣铸造温度对气孔率、硬度、显微组织(蒸发铸造结果)的影响。废旧铝的回收利用是减少铝废料的一种替代方法。铸造温度是一个可以影响铸造结果的变量,如果铸造温度低,那么在模具完全填充之前就会快速冻结。如果浇注温度过高,则会发生收缩,孔隙率值可能会增加。本研究使用了四种铸造温度变化,即:650°C, 700°C, 750°C和800°C。蒸发铸造法采用聚苯乙烯泡沫塑料的模式,堆积在砂型。被铸造的金属会形成类似泡沫塑料的图案。铸造温度测试的结果会影响气孔率、硬度和显微组织。

PENGARUH TEMPERATUR TUANG DENGAN JENIS MATERIAL PADUAN Al RONGSOK (KAMPAS REM PANCI) TERHADAP POROSITAS, KEKERASAN DAN STRUKTUR MIKRO HASIL PENGECORAN EVAPORATIVE
Recycling is a way of processing used materials that is started with selection, collection, then the process of foundry to create a new product that is more valuable economical. The objective of this research is to know the effect of casting temperature with the kind of guide material AI alloy junk from brake shoe and pan on porosity, hardness, microstructure (the evaporative foundry result). The recycling of used aluminum is an alternative to reduce the waste material from aluminum. Casting temperature is an variable that can effect the result of foundry where if the casting temperature is low, then there will be a quick freeze before the mold is completely filled. And if the casting temperature is too high, then shrinkage can occur and the porosity value may increase. This research used four casting temperature variations, namely: 650°C, 700°C, 750°C, and 800°C. The evaporative foundry method uses styrofoam pattern that is piled up into sand mold. The metal that is casted will form like styrofoam pattern. The result of casting temperature testing can effect on porosity, hardness, and microstructure.
