Provided are reusable magnesia-carbon refractories. The magnesia-carbon refractories of the present invention comprise a composition including 75 to 99.5 wt% of magnesia refractories and 0.5 to 25 wt% of graphite as a main raw material. The present invention further comprises 1 to 5 parts by weight of one or more additives of Al and Al/Mg alloy, 0.3 to 0.9 parts by weight of a low melting point coating agent, and 2 to 5 parts by weight of a phenol resin binder as a binding agent, with respect to 100 parts by weight of the main raw material.
재사용이 가능한 마그네시아 카본질 내화물이 제공된다. 본 발명의 마그네시아 카본질 내화물은, 중량%로, 마그네시아 내화재 75~99.5%와 흑연 0.5~25%를 포함하는 조성을 주원료로 하고, 상기 주원료 100 중량부에 대하여 Al과 Al/Mg 합금 중 하나 이상의 첨가제를 1~5 중량부; 저융점 코팅제를 0.3~0.9 중량부 및 결합제로서 페놀 레진 바인더를 2~5 중량부를 추가로 포함한다.
