New high-frequency cold-rolled ribbed steel bar annealing production line. Rational layout, stable, adjustable speed, easy operation, so the entire production line automation, continuous, high-speed operation. Not only significantly improve the cold-rolled ribbed bar elongation, while making technology, product quality, industrial scale to achieve a breakthrough. Chinese construction steel products by the Quality Supervision and Testing Center, the yield strength of 545-565Mpa, tensile strength 630-680Mpa, elongation A5.65. To reach 18.5% ~ 22.0%, high strength, good elongation, fully meet the 500Mpa The mechanical properties of steel.

New technology has the following characteristics:
(1) through the tempering temperature control technology to significantly improve product elongation, good mechanical properties, to overcome the low ductility of cold-rolled ribbed steel industry problems.
(2) cold rolling and tempering treatment combine to make the sum of two strengthening effect, grain refinement to improve the internal organization to improve the strength of steel, and to ensure the accuracy of the dimensions to become a science of cold rolling deformation heat treatment technology, to promote large-scale industrial development of products to achieve cold-rolled ribbed steel bar in the optimization of a major breakthrough in technology products.
(3) ordinary carbon steel as raw material, through cold and tempering treatment, the condition of yield strength to 500Mpa level, which means reduction using steel, mechanical properties, according to industry experts, each increase of steel strength level of 100MPa, Steel can save 10% to 20%. Way for the use of cold-rolled steel production of high-saving building opens up a new path. This is to improve cold-rolled ribbed steel production process and product optimization is about.

High-frequency sides of ribbed steel production line
Outstanding advantages: the layout is reasonable, stable, adjustable speed, easy operation, so the whole production line automation, continuous, high-speed operation.

Technical process:
1, with the following diameter 12 million hot-rolled steel plate machined threaded through the cold-rolled steel product size: Φ5, Φ7, Φ9, Φ11, Φ12
2, then by high-frequency electric heating equipment to make steel in the wear process of rapid water level increases from 850 down to 400 degrees, steel shiny black color rendering.
Features of steel after high frequency heat-treated :
1, the yield strength of 545-565Mpa, tensile strength 630-680Mpa, elongation A5.65. 18.5% 22.0%
2, high strength, good elongation, fully meet the 500Mpa mechanical properties of steel.
3, reinforced by the State Bureau of Quality Supervision testing over three steel standards.
