The invention discloses a preparation method of a metal composite ceramic blade for a rotary hearth furnace, the metal composite ceramic blade for the rotary hearth furnace comprises a metal base body and a ceramic part which are connected into a whole, the outer surface of the ceramic part is provided with a plurality of via holes which are arranged in a staggered mode, the cross section of each via hole is arranged in a circular or polygonal mode, and the metal base body and the ceramic part are connected into a whole. The plurality of via holes are formed in the metal matrix, so that the plurality of via holes are combined to form a honeycomb structure, and at least part of the metal matrix is located in the plurality of via holes; the preparation method of the metal composite ceramic blade for the rotary hearth furnace comprises the following steps that raw materials are mixed in a forming mold, and a ceramic piece is obtained after hardening; and the ceramic piece is fixed into a casting mold, the molten metal in the liquid state is injected, and the metal composite ceramic blade is obtained after cooling. When the blade is worn in use and cracks occur, the honeycomb structure can restrain development of crack cracking, the cracks are broken after being cracked to penetrate through the wall face of one through hole and cannot continue to extend, and therefore the cracks are automatically closed.
本发明公开一种转底炉用金属复合陶瓷叶片的制备方法，所述转底炉用金属复合陶瓷叶片包括连接为一体的金属基体和陶瓷件，所述陶瓷件的外表面设有交错设置的多个过孔，各所述过孔的截面呈圆形或者多边形设置，以使得多个所述过孔组合形成蜂窝结构，所述金属基体的至少部分处在多个所述过孔内；所述转底炉用金属复合陶瓷叶片的制备方法包括以下步骤：将原料在成型模具内混合，硬化后得到陶瓷件；将所述陶瓷件固定至铸造模具内，并将容融呈液态的金属注入，冷却后得到金属复合陶瓷叶片。当叶片使用磨损出现裂缝时，蜂窝结构的形式能够抑制裂缝开裂的发展，裂缝开裂至穿透一个过孔的壁面后断开，而无法继续延伸，从而将裂缝自行封闭。
