本文试以容积在1500米~3左右的岛式布置高炉车间大修设计为例,说明采用悬臂支座改造高炉支承结构的几个有关问题。悬臂支座在改造高炉支承结构中的地位为了适应高炉炉缸风力分布均匀、强化冶炼过程、出铁及时和缩短大修期等目的,要求在标高20米以下取消托圈和炉缸支柱,改为由大框架来支承炉身支柱(通过平台大梁)以上结构下传的荷载。但某厂炉体两侧的铁路正好妨碍大框架柱基的设置,而铁路的位
In this paper, we take an overhaul design of an island layout blast furnace workshop with a volume of about 1500 m~3 as an example to illustrate several problems related to the use of cantilever bearings to reform the blast furnace support structure. The position of the cantilever bearings in the reconstruction of the blast furnace support structure In order to adapt to the uniform distribution of the blast furnace hearth wind, strengthen the smelting process, timely iron out and shorten the overhaul period, etc. The large frame supports the load transmitted from the upper structure of the shaft (through the platform girder). However, the railroad on both sides of the furnace of a factory just happens to hinder the setting of the large-frame column base, and the position of the railway
