Abstract
1. Доменная печь, включающая летки для выпуска чугуна (шлака), воздушные фурмы, лещади и стенки горна из огнеупорных материалов, отличающаяся тем, что лещадь ее снабжена вертикально установленным искусственным огнеупорным выступом в форме конуса или в зависимости от формы стенок горна - любой другой форме, верхняя часть которого расположена в центре расположения противонаправленных фурменных очагов, а нижняя опирается на дно зумпфа. ! 2. Доменная печь по п.1, отличающаяся тем, что верхняя часть искусственного выступа выполнена в виде многослойной композиционной конструкции, а нижняя - сплошного огнеупорного диска, на который насаживается конусообразный выступ. ! 3. Доменная печь по п.1 или 2, отличающаяся тем, что искусственный огнеупорный выступ выполнен разборным, причем при разборке нижняя часть выступа отделяется в виде диска, а верхняя - по слоям композиционных конусообразных конструкций.1. A blast furnace, including slots for the production of pig iron (slag), air lances, flakes and walls of the hearth from refractory materials, characterized in that its flask is equipped with a vertically mounted artificial refractory protrusion in the form of a cone or, depending on the shape of the walls of the hearth, any other form, the upper part of which is located in the center of the location of the opposing tuyere foci, and the lower one rests on the bottom of the sump. ! 2. The blast furnace according to claim 1, characterized in that the upper part of the artificial protrusion is made in the form of a multilayer composite structure, and the lower one is a continuous refractory disk on which a conical protrusion is mounted. ! 3. The blast furnace according to claim 1 or 2, characterized in that the artificial refractory protrusion is made collapsible, and when disassembling, the lower part of the protrusion is separated in the form of a disk, and the upper part is separated by layers of composite conical structures.
