The invention belongs to the technical field of refractory material processing, and particularly relates to a multi-fiber reinforced magnesium-aluminum-carbon refractory material and a preparation process thereof. The process comprises the following steps: I, preparing raw materials, and mixing to obtain a prefabricated material; step II, putting the prefabricated material into a material container, and performing leveling treatment; step III, carrying out compression molding to obtain a molded blank; and IV, low-temperature firing treatment is conducted, and the refractory brick is obtained. The refractory material processed by the process comprises the following components in parts by mass: alumina, capacitance magnesia powder, magnesium aluminate spinel powder, polyethylene fiber, synthetic resin, alumina powder and graphite. Connecting rods are installed on the two sides of the material containing device respectively, the connecting rods are rotationally installed on a movable base, and the movable base i
