Blast furnace iron runner iron-containing material reaction device and smelting system

The utility model discloses a blast furnace iron runner iron-containing material reaction device and a smelting system, and belongs to the technical field of smelting. Iron-containing materials such as briquettes, scrap steel or metallized pellets are placed in the iron-containing material box, and the iron-containing material box is arranged on the supporting frame, located in the blast furnace iron runner and in contact with molten iron. After the arrangement, the iron-containing material is suspended in the iron runner under the action of the iron-containing material box and the supporting frame, the iron-containing material is scoured by the molten iron, harmful elements such as alkali metal in the iron-containing material react with the scoured molten iron to boil, and when the iron-containing material is melted into molten iron and leaks out of the iron-containing material box, the reaction of the alkali metal on the iron-containing material is completed; the harmful elements cannot react with the refra
