The utility model relates to a continuous decarburization annealing line for oriented silicon steel, in particular to a furnace end device of an oriented silicon steel decarburization annealing furnace, which comprises a furnace end and a furnace door positioned at the front end of a furnace body, a preheating device is further arranged at the front end of the furnace end and is a preheating furnace connected with the furnace end, and the preheating furnace comprises a furnace shell and heat preservation cotton located in the furnace shell. Energy released by hydrogen gas combusted by the furnace end and heated waste gas can enter the preheating device, the steel strip can be preheated through the preheating furnace, the temperature of the inner surface of the preheating section of the steel strip can rapidly reach 200-300 DEG C on the basis that electric energy or other energy consumption is not increased, and when the steel strip enters the heating section subsequently, the temperature of the inner surface
