Detailed description of the invention
As shown in Figure 1 and Figure 2, the high-performance fire-resistant door of the present embodiment include doorframe, door body, door hinge 5, Door closer 6, is hinged by described door hinge 5 between described door body and described doorframe, and closes described in passing through Door device 6 closes automatically, and described doorframe includes two frames 1 and top frame 2, forms door glyph framework, institute State door body and include door body four limit shrinking plate 8, panel 3, several supporting keels 4, described door body four limit Shrinking plate 8 constitutes frame structure, several described supporting keels 4 are horizontally-parallel be fixedly connected on described On door body four limit shrinking plate 8, form reinforced frame structure, play interior supporting function, prevent door frame distortions, The transverse section of described door body four limit shrinking plate 8 is in bow font, and described panel 3 covers reinforced frame knot comprehensively The two sides of structure, all fill anti-between two described panels 3 and in described frame 1, in described top frame 2 Pyroxylin 7, described frame 1, described top frame 2, described door body four limit shrinking plate 8, described panel 3, institute Stating supporting keel 4 all uses fire-resistant and weather-resistant steel to make；Described frame 1 includes framework 11, sealing limit 12, It is provided with door hinge corresponding to described door hinge 5 junction in described framework 11 and strengthens connecting bottom board 9, described framework 11, described sealing limit 12, described door hinge are strengthened connecting bottom board 9 and are all used fire-resistant and weather-resistant steel to make；Described Fire-resistant and weather-resistant steel include the chemical composition of following percentage by weight: C 0.08～0.12%, Si 0.30～ 0.60%, Mn 0.50～1.50%, S≤0.03%, Cr 0.40～0.80%, Mo 0.25～0.40%, Nb 0.02～0.04%, P 0.05～0.12%, Cu 0.25～0.55%, Ni 0.04～0.07%, V 0.02～ 0.08%, N 0.011～0.020%, Ti 0.008～0.016%, Zr≤0.02%, remaining is Fe and not Evitable impurity, this steel belongs to low-alloy steel, and the target content of each essential element is as follows: C 0.10%, Si 0.45%, Mn 1.00%, S 0.03%, Cr 0.60%, Mo 0.30%, Nb 0.03%, P 0.10%, Cu 0.40%, Ni 0.055%, V 0.05%, N 0.015%, Ti 0.008%, Zr 0.02%.
The warp test to the fire-resistant and weather-resistant Steel Properties of the present invention, either ambient temperature mechanical properties, or Mechanical property under the high temperature of 600 DEG C is obtained for effective improvement.Overall trend is, tries after sofening treatment Testing and reduce by the intensity of steel, plasticity improves.Along with the rising of temperature, yield strength declines, during by 18 DEG C 484.20MPa 350.00MPa when dropping to 600 DEG C, yield strength declines 134.20MPa, rate of descent 27.7%.The test steels after softening yield strength under 600 DEG C of high temperature is room-temperature yield strength 72.3%, exceed the 2/3 of room-temperature yield strength.Meanwhile, tensile strength is the most on a declining curve, And the downward trend of tensile strength is more than the downward trend of yield strength.After normalizing at temper softening The room-temperature property of the fire-resistant and weather-resistant test steel after reason is superior to common building steel, arrives improving intensity During 500MPa level, elongation percentage is still up to more than 24%.And there is good high-temperature behavior, 600 DEG C Time yield strength be only the 72.3% of room-temperature yield strength, exceeded the 2/3 of room-temperature yield strength, meet The requirement of Fire-resistant Steels Used in Buildings, and the yield strength that common building steel is when 600 DEG C is far smaller than room temperature The 2/3 of yield strength, it is impossible to guarantee the bearing safety of building.It addition, the fire-resistant and weather-resistant steel to the present invention Corrosion resisting property carry out salt air corrosion experiment show, along with the prolongation of etching time, the weightlessness of test steels The increase trend straight carbon steel to be less than of speed, the order of corrosion weight loss be test steels < compared steel, this Illustrating that the corrosion resistance relatively common building steel of fire-resistant and weather-resistant steel to be got well, the year thinning speed of compared steel is 2.4908mm/a, and the year of test steels thinning speed is only 1.1239mm/a, its decay resistance is Reach more than 2 times of compared steel.In sum, by becoming to set up separately to the fire-resistant and weather-resistant steel of the present invention Meter, it is determined that test steels composition characteristic, is met the fire-resistant and weather-resistant steel test steel of performance.And Its processing performance, sofening treatment and fire-resistant and weather-resistant performance are studied and tested.
Can draw the following conclusions from test and analysis.In aspect of performance, test steels room temperature yield strength 484.20MPa, tensile strength 573.59MPa, elongation after fracture 24.44%, yield strength when 600 DEG C The 72.3% of 350.00MP, only room-temperature yield strength, has exceeded the 2/3 of room-temperature yield strength, meets resistance to Fire performance requirement；Salt spray test result, compared steel year, thinning speed was 2.4908mm/a, and test steels Being only 1.1239mm/a, its decay resistance has reached more than 2 times of compared steel, has met weather resistance Requirement.Compared with steel similar with other, the ambient temperature mechanical properties of the high-performance fire-resistant door of the present invention is more preferable, Strength plastic is higher, and weather resistance is superior.
In the composition of the fire-resistant and weather-resistant steel of the present invention, the unit improving fire resistance have Cr, Mo, Nb, The unit improving weather resistance have Cu, P, Ni, Cr, and V-N steel unit have Ti, V, Nb etc.. It addition, Zr can add in right amount according to corrosion proof requirement or without.
The present invention is using fire-resistant and weather-resistant steel as doorframe, panel material, and adds skeleton between panel, it is possible to increase Add fire resistant doorsets design service life and make its in high temperature environments yield strength decline after be still not less than regulation Room-temperature yield strength standard, therefore, it is possible to door-plate is seriously become by high-temperature baking when preventing fire Shape, thus prevent the too much seepage poison gas of fire resistant doorsets or prevent from missing because deformation causes not opening door Escape Best Times.The present invention has opened up a kind of new application of the fire-resistant and weather-resistant steel of special component.
The composite can be widely applied to fire resistant doorsets field.
