The present invention provides a heating furnace gunning material capable of carrying out thermal state online repair, wherein the heating furnace gunning material comprises 40-80 wt% of high bauxite clinker;, 10-25 wt% of fused magnesia, 5-10 wt% of aluminum magnesium spinel, 1-3 wt% of kyanite, 5-20 wt% of a binder, 0.1-0.5 wt% of sodium tripolyphosphate, 0.05-0.2 wt% of sodium polyacrylate, and 0.5-3.0 wt% of aluminum powder. According to the present invention, when the gunning material is used to repair the heating furnace, the thermal state online repair can be achieved by using the gunning machine, the spraying gun and other gunning equipment, the repair is rapid, and the efficiency is high; and after the gunning material is used to repair the collapsed part having the thickness of 20 cm and on the top portion of the heating furnace, the adhesion performance of the gunning material is good, the bond strength between the gunning material and the repaired work surface is high, and the fire appearing or damage peeling phenomenon does not generated 10 months after the heating furnace is repaired.
