Not fire-resistant steel heat Chongzuo steel, when the temperature is below 150 ℃ when Liuzhou Steel, steel properties changed little. Therefore suitable for hot steel plant, but the heat radiating structure of the surface by about 150 ℃, to be used to protect the thermal shields. Temperature steel strength and elastic modulus decreased significantly at 300 ℃ -400 ℃, the temperature is about 600 ℃, the strength of steel tends to zero. With special needs in the fire building, steel refractories must be protected in order to improve the fire resistance rating. Steel types are: for the bent structure plant, multi-frame structure for high-rise buildings, the frame of a wall structure, frame a Fangchenggang steel tube structure, large space grid structure for flat and curved top Net charge structure and so on. Construction of different functions, use of different structure. Steel structure design specification to be executed countries, so technologically advanced, economical, safe and practical, to ensure quality.
