  • The development of technology to prevent environmental pollutants and reduce energy consumption has already become a very significant issue not only for the foundry industry but also for society as a whole. In this paper, we introduce a new dust collector developed for low energy consumption and high performance compared to a roof top dust collector. The roof top dust collector which is using widely in the domestic foundry plant has a low performance about the dust suction ability in spite of high energy consumption because it is installed in a high place to collect the whole dust from all processes in foundry. A dust collector away from dust sources inevitably has low energy efficiency. The development of an efficient collector for foundry is very difficult because the position of the dust source continues to change from the melting process to the pouring process. New dust collector is installed on the ladle transfer equipment such as cranes, hoists, and monorails to effectively respond to moving dust sources. The movable device, attached close to the source of dust, provides high performance even with low energy consumption. The new dust collector is expected to be an environment-friendly device that can be applied to the foundry.

  • 주물작업이란 용융된 금속을 미리 준비한 주형에 부어 원하는 형태의 주물을 만드는 금속성형작업으로서, 생산 공정에서 고열을 이용하여 금속을 용해, 주조하는 등의 작업 특성상 부유분진의 발생이 필연적이며, 일산화탄소, 금속 흄, 휘발성 코울타르 피치, 소음 및 진동, 고열, 전리방사선 등의 유해인자로 인한 피해가 극심하다. 특히 분진은 주물의 생산공정 중 용해, 조형, 탈사 및 후처리 등 거의 전 공정에서 발생되며, 결정형 유리규산(SiO$_2$)을 다량 함유하고 있어 인체에 흡입되었을 때, 건강의 악화 및 직업병의 원인으로서 작업 능률을 떨어뜨리는 요인으로 작용하고 있다(Burgess, 1995).

  • The purpose of this study is to examine the raising of strength of concrete and workability using casting foundry fly ash. First, we conducted analysis of chemical components of fly ash. Then, we tested uniaxial strength of concrete at ages of 3, 7, and 28 days. As a result, we found that the strength of concrete using casting foundry fly ash is raisen up 16% than plain concrete when the fly ash is added 0.6% of weight of cement.
