Zusammenfassung:	The invention provides a heat-dissipation wear-resistant seamless steel tube plug and a preparation method thereof. The seamless steel tube plug comprises a plug base body, the end of the plug base body is covered with a cladding layer, the cladding layer is covered with a ceramic alloy layer, and the ceramic alloy layer extends to cover the whole plug base body; a cooling structure is arranged in the plug base body and comprises air inlet channels and exhaust holes, the air inlet channels are formed in the axis direction of the plug base body, the hole diameters of the air inlet channels are gradually reduced in the extending-in direction, and air outlet channels are evenly distributed around the axis. The cladding layer and the ceramic alloy layer cover the plug base body, the hardness and wear resistance of the plug are improved, the air outlet channel is arranged to be in a spiral coiling type, on one hand, the path length of the air outlet channel is increased, the contact area of cooling airflow and the
