[0025] Such as figure 1 As shown, the present invention provides a hot blast stove device for blast furnace ironmaking, comprising a furnace body 1, a furnace grate 2 is installed at the bottom of the inner wall of the furnace body 1, and a cold air pipe 3 is fixedly installed at the bottom of the side wall of the furnace body 1 And the waste gas pipe 4, the top of the side wall of the furnace body 1 is fixedly equipped with a hot air pipe 5, the cold wind pipe 3 and the waste gas pipe 4 are parallel and both are symmetrical about the center of the furnace body 1, so that the cold wind pipe 3 enters the cold wind and the waste gas pipe The 4 rows of exhaust gas do not interfere with each other, and the efficiency is higher. The furnace grate 2 is located between the cold air pipe 3 and the exhaust gas pipe 4. The furnace grate 2 has two functions here. First, it makes the cold air entering from the cold air pipe 3 Evenly spread to the regenerator 6, so that the cold air is hea...
