Claims (1)

조립자로 분쇄된 도로 마이트를 300℃ 정도의 온도로 가열하여 산화마그네슘(MgO)의 함량이 30% 이상인 입자상의 다공성 내화재를 얻은 다음, 이를 교반기에 투입하고 이에 조성물 15%인 타르를 혼합 70℃ 온도로 20-30분간 교반하면서 휘발성 용제를 투입함을 특징으로 하는 용광로등의 노상 보수재의 제조방법.The road mite crushed by the coarse granules was heated to a temperature of about 300 ° C. to obtain a porous porous refractory material having a magnesium oxide (MgO) content of 30% or more. Process for the manufacture of roadbed repair materials, such as furnaces, characterized in that the volatile solvent is added while stirring for 20-30 minutes. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
