Beschreibung
Zusammenfassung:	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.
