首钢四焦炉硫铵车间经常遭受从生产设备中跑、冒、滴、漏的酸液腐蚀和机械设备的撞击,使用十年后,厂房建筑因严重腐蚀而被破坏。新建四焦炉硫铵车间厂房建筑的防腐蚀设计,采取了以“预防为主、重点设防”为主的设计原则,积极设防,排除产生腐蚀介质的根源,控制腐蚀范围,并在建筑结构选型、节点构造及建筑防腐蚀材料等方 Shougang’s four-coke furnace ammonium sulfate plant often suffers from acid corrosion and run-up from machinery, equipment, drips, and leaks, and mechanical equipment. Ten years later, plant buildings were damaged due to severe corrosion. The anti-corrosion design of the building of the new four-coke furnace anthraxic acid workshop has adopted the design principle of “prevention as the main, key defense” as the main design principle, actively setting the defense, eliminating the root cause of corrosive media, controlling the corrosion range, and selecting the architectural structure. Type, node structure and construction anti-corrosion materials etc.
