Unshaped refractory material and preparation method thereof
The invention provides an unshaped refractory material and a preparation method thereof. The unshaped refractory material contains the components in parts by weight: 5-30% of magnesia particles, 5-15% of caustic-burned magnesia powder, 20-45% of corundum, 10-20% of silicon carbide, 10-18% of cokes, 6-12% of clay, 2-8% of ferro-silicon nitride, 3-10% of graphitisable coal tar pitch and 12-14 parts of a graphitisable binder which is liquid at normal temperature. The preparation method comprises the steps of mixing the magnesia particles, the caustic-burned magnesia powder, the corundum, silicon carbide, the cokes, the clay, ferro-silicon nitride and the graphitisable coal tar pitch according to a certain proportion; and then, grinding and mixing after adding the liquid graphitisable binder to obtain the unshaped refractory material.
