Abstract

FIELD: ferrous metallurgy. SUBSTANCE: open hearth furnaces vertical flues and slag pockets refractory lining is changed for water cooling panels. Panels are made of steel sheets, cooling pipes bent in the form of cramps with interpipe space filled with refractory concrete. Between steel wall and concrete there is layer of thermoinsulation. Space between axes of cooling pipes is 2.4 - 2.7 and concrete layer thickness is equal to 3.2 - 4 outer diameters of cooling pipe. EFFECT: decreased open hearth furnace operation costs.

Предложено заменить в вертикалах и шлаковиках мартеновских печей огнеупорную кладку водоохлаждаемыми панелями. Панели состоят из стальных листов, охлаждаемых труб, изогнутых в виде скоб, с межтрубным пространством, заполненным огнеупорным бетоном. Между стальной стенкой и бетоном предусмотрен слой термоизоляции. Расстояние между осями охлаждаемых труб 2,4-2,7, а толщина слоя бетона 3,2-4 наружного диаметра охлаждаемой трубы.It is proposed to replace the refractory masonry in the verticals and slag of open-hearth furnaces with water-cooled panels. The panels consist of steel sheets, cooled pipes, bent in the form of brackets, with an annulus filled with refractory concrete. A layer of thermal insulation is provided between the steel wall and concrete. The distance between the axes of the chilled pipes is 2.4-2.7, and the thickness of the concrete layer is 3.2-4 of the outer diameter of the chilled pipe.
