鞍钢某号高炉的容积原为1513立方米,大修扩大为1812立方米,相当于增加一座中型高炉。高炉本体原结构型式是炉缸支柱同炉身支柱分开的,各有6根支柱。炉身支柱承受的荷重,经由托圈传至炉缸支柱。炉顶设备和炉喉平台的荷重,由炉身支柱上部与板梁构成的六角空间体系来承受。斜桥有独立的支柱,是一简支外伸梁,其外伸部分插 The volume of an Angang blast furnace was originally 1,513 cubic meters, and the overhaul was expanded to 1,812 cubic meters, which is equivalent to the addition of a medium-sized blast furnace. The original structure type of the blast furnace body is that the hearth pillar is separated from the body pillar and each has six pillars. The load on the shaft of the furnace body is transmitted to the furnace pillar via the ring. The load on the furnace top equipment and throat platform is absorbed by the hexagonal space system formed by the upper part of the shaft of the furnace body and the plate girder. The oblique bridge has an independent pillar and is a simply-extended beam with its outreach partially inserted.
