Claims8
A casting sliding gate comprising:
- a plurality of plates,
- wherein each of the plates comprises an inner body having an opening formed therein and an outer body disposed outside of the inner body, the opening forming a movement path of molten steel,
- the inner body, which directly contacts the molten steel, comprises carbon fibers and carbide, and the outer body comprises an Al2O3—ZrO3—SiO2—C-based refractory material, and
- the inner body comprises 40-50 wt % of the carbon fibers and 50-60 wt % of the carbide with respect to a total weight of the inner body.
