Abstract
The utility model relates to a hot air outlet pipe of a hot blast stove, and effectively solves the problems that brick masonries among the walls of a combustion chamber are destroyed, an arch crown collapses, air is released from the hot air outlet pipe, and the service life of a blast furnace hot blast stove is short. An inner brick layer is arranged outside an outer brick layer; a composite brick is arranged outside the outer brick layer; heavy brick supporting layers are arranged below a semi-ring composite brick behind the composite brick; a semi-circular steel fiber casting material arch ring is arranged above the semi-ring composite brick; supporting bricks are arranged on the outer side of a junction of the semi-ring composite brick and the semi-circular steel fiber casting material arch ring; fixed bricks are arranged outside the supporting bricks; spraying layers are arranged outside fiber cotton felt layers outside light brick layers between the inner heavy brick layer of the combustion chamber and a stove shell, and extend into an outlet pipe on the outer wall of the stove shell; the fiber cotton felt layers and the light brick layers are arranged on the spraying layers in sequence; and the light brick layers are connected with the outer brick layer. When the stove shell upward displaces due to thermal expansion and the brick masonries in the combustion chamber downwards displace due to thermal shrinkage, various stress at the junction can effectively absorbed or resisted, and the problems of the serious damage of the hot air pipe and the damage of the arc crown are avoided.
