Abstract
A kind of high-intensity special-shaped steel of the utility model, comprise one block of high strength web and be welded thereon on end and lower end two pieces with the high strength wing plate of arc-shaped, be welded with bending structure respectively at the two ends of described wing plate.The utility model adopt hot rolling wing plate is rolled on cross section with arc-shaped, and be welded with bending structure respectively at the two ends of wing plate, add the ability of cross-section area and resistance to compression, shearing stress, the H shaped steel increase by 10 ~ 15% that bearing capacity ratio is common, has the advantage that bearing capacity is strong, shock resistance is good.
Description
Technical field
The utility model relates to a kind of high-intensity special-shaped steel.
Background technique
At present, H shaped steel is divided into hot rolling and welding production two kinds by processing technology, and it is as a kind of multipurpose
Economic section section bar, most use is Q235, Q345 steel, though in China's building construction, be particularly used widely at field of steel structure, there is the shortcomings such as intensity is low, waste steel resources, befouling environment, cost of production are higher.
Summary of the invention
The problems such as, waste steel resources, befouling environment, cost of production low for the hardness of steel existed in prior art are higher, the utility model proposes a kind of high-intensity special-shaped steel.
The technical solution of the utility model is: a kind of high-intensity special-shaped steel, comprise one block of high strength web and be welded thereon end and lower end on two pieces with the high strength wing plate of arc-shaped, be welded with bending structure respectively at the two ends of described wing plate.
Preferably, the yield strength >=600 ~ 1700Mpa of described deformed steel.
The useful effect that the utility model has is: the utility model adopt hot rolling wing plate is rolled on cross section with arc-shaped, and be welded with bending structure respectively at the two ends of wing plate, add the ability of cross-section area and resistance to compression, shearing stress, the H shaped steel increase by 10 ~ 15% that bearing capacity ratio is common, has carrying
The advantage that power is strong, shock resistance is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-intensity special-shaped steel of the utility model;
In figure: 1 web, 2 bending structures, 3 wing plates.
Embodiment
By reference to the accompanying drawings the utility model is described further:
As described in Figure 1, a kind of high-intensity special-shaped steel, comprise one block of high strength web 1 and be welded thereon on end and lower end two pieces with the high strength wing plate 3 of arc-shaped, be welded with bending structure 2 respectively at the two ends of described wing plate, the yield strength >=600 ~ 1700Mpa of described deformed steel.
Chemical composition C: 0.15%, Si: 0.22%, Mn: 1.8% is pressed by steel mill; Select three kinds of trace alloying elements Ni: 0.01%, Nb: 0.04%, Cr: 0.06% with remainder for Fe has smelted steel billet, and the good web of heating rolling and the wing plate with bending angle and arc-shaped, simultaneously, get out traction gear, oven, tempering oven, tempering cooling unit, and switch on power, high-pressure water pump connected by annular quenching unit; Again web, wing plate are transported to following process place, draw through traction gear, by transmission bracket as carriage drive, send into oven successively and carry out Segmented heating, be heated to 855 DEG C, then by annular quenching unit carry out for time 5 second rapid quenching, then 600 DEG C of tempering are heated to through tempering oven, finally by tempering cooling unit cooling processing to normal temperature, so just, produce high strength web and high strength wing plate that yield strength is 710MPa, its inside metallographic is the sorbite that grain size reaches 9 grades; Finally by two blocks of high strength wing plates, adopt high frequency butt welding machine on the web upper end being welded in web and web lower end.
Last it is noted that the foregoing is only explanation mode of execution of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. a high-intensity special-shaped steel, is characterized in that, comprise one block of high strength web and be welded thereon end and lower end on two pieces with the high strength wing plate of arc-shaped, be welded with bending structure respectively at the two ends of described wing plate.
2. high-intensity special-shaped steel according to claim 1, is characterized in that, the yield strength >=600 ~ 1700Mpa of described deformed steel.
