The invention provides a blast furnace hot-blast stove orifice combination brick structure relating to the technical field of thermal engineering. Based on a key technology of building an elliptical ring by ingeniously using T-shaped and L-shaped refractory bricks, according to the practical situation of the diameter size of a blast furnace hot-blast stove orifice, the combination brick structure is composed of an outer ring, a neighboring outer ring, an inner ring and a neighboring inner ring, wherein the outer ring and the neighboring outer ring of which the inner diameters are shaped like an ellipse are built by using one T-shaped refractory brick for the ring top and the ring bottom respectively and using L-shaped refractory bricks both sides of the ring; the inner ring and the neighboring inner ring of which the outer diameters are shaped like an ellipse are built by using sealed refractory bricks; the outer ring and the neighboring outer ring as well as the inner ring and the neighboring inner ring are
