马钢1~#高炉风口平台出铁场平坦化设计和实践

Causes and Control of Deformation Joints of Masonry Structures

马钢1^#高炉为2500 m^3高炉,风口平台及出铁场设计为双矩形出铁场[1],三铁口布置,无渣口,渣铁沟合理布置,铁水摆动流嘴,出铁场平坦化,炉前设备选型机械化程度高,采用除尘设施改善出铁场操作环境。

Currently,there are various forms of cracks masonry structure building,is very common,its fracture degree weight is differ,difference is very big,the light and the normal use of the building and beautiful,will form the structure of serious security hidden danger,even through the analysis of engineering accident,cause many of the causes of cracks on the masonry structure,have a plenty of foundation,temperature,shrinkage,also have a plenty of design,construction and the cause of the material.Here,the masonry structure crack is divided into two categories:stressed crack and non-stressed crack.The cracks generated by the structure under various direct loads are called stressed crack,while the cracks caused by shrinkage,temperature,humidity change and uneven foundation settlement are non-stressed crack,also known as deformation crack.
