As HRB500E spiral is effectively promoted in a large amount of uses of key state project in recent years, and each life at present
The production technology for producing enterprise is different, causes cost of alloy different, for this problem, expands and protrude into analysis and research, from smelting
Technique is added to control tissue from alloy and is optimized, to reduce the use of rare alloy element, surely to rolling mill practice
Determine properties of product.
Summary of the invention:
In order to solve the above-mentioned technical problem, the formula constituent for optimizing high-performance anti-seismic steel bar, the high property prepared according to the formula
The properties of product of energy anti-seismic steel bar are stablized, and improve welding performance, reduce the use of rare alloy element.Superior performance, drop
Low production cost, improves economic benefit.
The technical solution adopted by the present invention are as follows: the ingredient of a kind of high-performance anti-seismic steel bar, the high-performance anti-seismic steel bar is matched
Than are as follows: C is 0.21~0.24wt%, and Si is 0.30~0.50wt%, and Mn is 1.30~1.55wt%, and V is 0.04~0.08%,
S≤0.035wt%, P≤0.035wt%, N 90-120ppm, surplus are Fe and inevitable impurity.
Further, the composition proportion are as follows: C 0.225wt%, Si 0.4wt%, Mn 1.42wt%, V are
0.6%, S 0.017wt%, P 0.017wt%, N 105ppm, surplus Fe.
Further, a kind of yield strength 540-600MPa, tensile strength 680- is prepared according to the component prescription
The high-performance anti-seismic steel bar of 780MPa and strong flexor ratio 1.29-1.36.
Beneficial effects of the present invention: a kind of formula constituent of high-performance anti-seismic steel bar more optimized is provided, according to this
Its yield strength of high-performance anti-seismic steel bar of formula preparation is 540-600MPa, tensile strength 680-780MPa, and strong flexor ratio is
