The invention discloses an iron tap channel swing spout prefabricated piece. The iron tap channel swing spout prefabricated piece comprises different particulate finesses of dense corundum, different particulate finesses of tabular corundum, silicon carbide, tabular corundum powder, silicon carbide powder, active alumina powder, graphite powder, ferro-silicon nitride, asphalt powder, boron carbide, borosilicate glass powder, calcium aluminate cement, silicon powder, anti-explosion fiber and sodium hexametaphosphate. A production method of the iron tap channel swing spout prefabricated piece comprises the steps that the various raw materials are mixed, water is added, the mixture is stirred and then poured into a mold for pouring forming, demolding is conducted after forming, and then maintenance is conducted; the maintained product is placed in a firing furnace, the temperature is raised and then kept, the temperature is then lowered at a constant speed and then kept; the temperature is raised at the temperature rising speed, and then the temperature is kept; and natural cooling is conducted. The iron tap channel swing spout prefabricated piece and the production method of the iron tap channel swing spout prefabricated piece have the advantages that the prepared iron tap channel swing spout prefabricated piece has good anti-scouring performance, high-temperature strength and oxidation resistance and can keep high iron flux, and the iron tap channel swing spout prefabricated piece has the important functions on shortening the length of an iron tap channel, reducing the area of a cast house, improving the flushing and casting conditions, reducing the maintenance expense of the iron tap channel and reducing the energy consumption of per ton of iron.
