Abstract

Изобретение относится к конструкции подовой зоны металлургической печи (1), включающей подовую часть (2) и стенку (3), каждая из которых включает стальную конструкцию (6, 21), образующую наружную поверхность, и огнеупорную внутреннюю кирпичную футеровку (12), причем подовая часть (2) и стенка (3) соединены между собой; стенка (3) печи (1) разделена на нижнюю часть (4) и верхнюю часть (30), причем стальная конструкция (21) нижней части (4) представляет собой отдельное кольцо, состоящее из частей (23), между которыми предусмотрены соединения (19), выполненные с возможностью расширения. Изобретение дополнительно относится к способу контроля расширения печи (1).The invention relates to the design of the hearth of a metallurgical furnace (1), including a hearth (2) and a wall (3), each of which includes a steel structure (6, 21) forming the outer surface and a refractory inner brick lining (12), and the hearth part (2) and the wall (3) are interconnected; the wall (3) of the furnace (1) is divided into the lower part (4) and the upper part (30), and the steel structure (21) of the lower part (4) is a separate ring consisting of parts (23), between which there are connections ( 19), made with the possibility of expansion. The invention further relates to a method for controlling expansion of a furnace (1).
