Embodiment 1

[0022] A fireproof door with a protective titanium alloy plate, the door includes an external protective titanium alloy plate, a fireproof coating coated on the outer surface of the protective titanium alloy plate, and a concrete door blank wrapped in the protective titanium alloy plate, said Concrete door blanks consist of concrete and circular steel pipes inside the concrete,

[0023] The element composition of titanium alloy plate is: Cr 2.5%, Al 1.5%, Mo 0.75%, Fe 0.65%, Mg 0.25%, Cu0.055%, Sn 0.045%, Y 0.015%, the balance is titanium and unavoidable non-metallic Inclusions are smelted according to the composition of the above elements, poured into a slab, and the slab is hot-rolled at a temperature of 900°C, the deformation of each pass is 15%, and the total deformation is 60%. After hot rolling, it is air-cooled to room temperature, and the plate is removed surface oxide film, then cold-roll the plate to reduce the thickness of the plate by 6%, then carry out stress-reli...

Abstract

The invention relates to a fireproof door with a protection titanium alloy plate. The fireproof door comprises a protection titanium alloy plate outside, a fireproof coating coated on the outer surface of the protection titanium alloy plate and a concrete door blank wrapped inside the protection titanium alloy plate, wherein the concrete door blank comprises concrete and a circular steel tube inside the concrete, and the steel tube is made from an iron-based material, so that the load bearing strength requirement can be effectively guaranteed, and concrete contact and corrosion resistance are good. The concrete material is made from multiple mixed materials, the compressive strength reaches 32MPa (7d) and 48MPa (28d), and the fireproof coating improves the fireproof performance of the fireproof door.

Description

technical field [0001] The invention relates to a fireproof door with a protective titanium alloy plate, which belongs to the field of door industry manufacturing. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. Analyzing the mechanical characteristics of fire doors, it can be found that when the fire doors are subjected to impact loads, the door body will bear a large out-of-plane bending moment, and it is unreasonable to use steel beam concrete columns to resist this bending moment: steel beams are due to Its material characteristics have good bending performance, and it is easy to buckle under compression. With the occurrence of various safety incidents, the requirements of fire protection engineering for d...
