摘要： 본 발명은 스테인레스 정련슬래그를 아스콘 채움재로 제조하는 방법에 관한 것으로, 그 목적은 습식냉각 대신 건식냉각공정을 채택하여 냉각과정에서 디칼슘실리케이트(2CaO·SiO
2 )의 상전이에 의한 자연분화현상을 유도함으로써 별도의 분쇄공정을 거치지 않고서도 아스콘 채움재의 입도규격을 만족하도록 하여 스테인레스 정련슬래그를 아스콘 채움재로 제조하는 방법을 제공하는 것이다.
상기 목적을 달성하기 위한 본 발명은,
고온의 스테인레스 정련슬래그를 건식냉각하는 단계,
건식냉각한 분말을 250㎛ 이하로 체거름 하는 단계를 포함하여 이루어지는 스테인레스 정련슬래그를 아스콘채움재로 제조하는 방법에 관한 것을 그 기술적 요지로 한다. 본 발명에 따르면 별도의 분쇄공정을 거치지 않고도 스테인레스 정련슬래그를 아스콘 채움재로 활용할 수 있어 경제적이면서 다른 채움재와 같이 중금속이 용출되는 문제점도 없으며, 전혀 수분과 접촉되지 않아 아스콘 채움재의 필수 요건인 건조된 상태를 만족함으로 함수분을 포함하는 다른 채움재에 비교하여 건조 공정을 거치지 않기 때문에 제조공정이 간단하다.
