The invention relates to a wire penetrating guide grid plate for an annealing furnace. The wire penetrating guide grid plate comprises an annealing furnace body, annealing pipelines and a water tank, wherein the annealing pipelines penetrate through the annealing furnace body, the water tank is arranged at outlets of the annealing pipelines, a wire penetrating guide grid plate assembly is arranged in the water tank and comprises a pair of grid plates and felt, the pair of grid plates is erected in the water tank, the felt is clamped between the pair of grid plates, and copper wires led out from the annealing pipelines penetrate through the felt. The grid plates and the felt are matched with one another to guide the copper wires, so that the copper wires can penetrate through the felt, and the felt realizes a water blockage effect, and is low in cost and convenient to replace.
