The invention provides a method for producing a high thermal conductivity and high wear refractory material, and the method comprises the steps shown in FIG. 1 : 1) adding one or several high thermalconductive materials to a matrix in a silicon carbide material; 2) adding non-water resin to serve as a binder, mixing, and forming a blank according to the shape demand; 3) at high temperature in a nitriding atmosphere, performing heat preservation firing to form a product; 4) maintaining the high temperature in a sealed atmosphere furnace, and in a high negative pressure environment, siliconingthe product through silicon vapor pair. The product produced by the method has high thermal conductivity, good wear resistance and excellent high temperature performance, and the service life of calciner equipment made prepared by using the product is obviously prolonged. 本发明提供种高导热高耐磨耐火材料的生产方法，具体包括如图1所示步骤：1)在碳化硅质材料中的基质中添加种或几种高导热材料；2)加入无水树脂做结合剂，混合后按需求形状制坯；3)在氮化气氛下高温，保温烧制成制品；4)在密封的气氛炉内保持高温,高负压环境，通过硅蒸汽对所述制品渗硅。通过该方法生产的制品导热系数高、
