Abstract
The present invention provides special base material for making nails and cold rolling ribbed steel bars. The present invention is characterized in that the present invention is steel having the following chemical composition: 0.07 to 0.16 wt % of C, 0.10 to 0.30 wt % of Si, 0.30 to 0.60 wt % of Mn, 0 to 0.035 wt % of S, 0 to 0.035 wt % of P, and balancing Fe and unavoidable impurities. Accordingly, obtained special base material for making nails and cold rolling ribbed steel bars has the characteristics of high precision of external dimension, good surface quality, complete intensity grade and specification, low cost, stable steel bar cleaning property, etc.; wires can not be easily broken in the rolling process, the stability of the base material in the cold working process can be ensured, production accidents can be reduced, and the property qualified rate of cold rolling ribbed steel bars can be notably improved; the technical level of engineering construction and the engineering quality are improved in use, the consumption of raw material is reduced, engineering cost is reduced, and appreciable social benefits are obtained.
Description
Technical field
The present invention relates to a kind of preparation method, belong to the design and the manufacturing technology field of metallic substance for the mother metal of making nail and cold rolled reinforcing steel bar with ribs special use.
Background technology
Cold rolled reinforcing steel bar with ribs is a kind of new and effective structural steel that begins to introduce China the 1980s, has the intensity height, and is strong with concrete bond stress, can save characteristics such as steel and cement.As in cast in place concrete plate, use cold rolled reinforcing steel bar with ribs can save steel more than 30%; In prestressed concrete member, behind the use cold rolled reinforcing steel bar with ribs, can save cement 50kg/m3～80kg/m3, and can significantly improve concrete quality, therefore use comparatively extensive.But the employed raw material of existing cold rolled reinforcing steel bar with ribs is low-carbon (LC) gren rod for building mostly, in use there is following problem: 1) gren rod poor quality, wire surface ferric oxide skin depth, tolerance of dimension is bigger, directly influences the rolling qualification rate of cold rolled reinforcing steel bar with ribs.2) the big and S of the chemical component fluctuation of wire rod, P content height, easily segregation and contain inclusion, make wire rod in drawing process, usually cause fracture because of component segregation or inclusion content are high, both influence the production output of cold rolled reinforcing steel bar with ribs, influenced the quality product of cold rolled reinforcing steel bar with ribs again.3) poker characteristic of wire rod is inhomogeneous, makes cold rolled reinforcing steel bar with ribs under normal working condition, one section qualified one section underproof phenomenon can occur.4) low-carbon (LC) gren rod for building can not satisfy the needs of producing other cold rolled reinforcing steel bar with ribs of different intensity scale.Because above-mentioned deficiency makes that the qualification rate of cold rolled reinforcing steel bar with ribs is lower, directly influences its output and quality, therefore, is necessary prior art is improved.
Summary of the invention
The object of the present invention is to provide a kind of stable performance, the product percent of pass height, poker characteristic is good, and production cost is low, intensity rank and complete in specifications, the preparation method of precision height, the measured system nail of matter and dedicated base material for cold rolling reinforced steel-bar with ribs.
The present invention realizes by following technical proposal: a kind of preparation method who makes nail and dedicated base material for cold rolling reinforced steel-bar with ribs, it is characterized in that the steel that it is following with chemical ingredients: C 0.07-0.16wt%, Si 0.10-0.30wt%, Mn 0.30-0.60wt%, S≤0.035wt%, P≤0.035wt%, all the other are Fe and inevitable impurity; Form by following technology is rolling: it is to be heated to the open rolling when reaching 950～1050 ℃ of strand temperature in 1000～1150 ℃ the process furnace that above-mentioned steel billet is sent into temperature, through roughing, in roll, after each 6 passage of pre-finish rolling, under 800～920 ℃ of temperature, carry out finish rolling, the lopping of under 880～940 ℃ of temperature, weaving silk after the finish rolling, with roller speed is on the roller-way of 0.20～0.50m/s, make the wire rod temperature be cooled to 680～800 ℃ earlier by 850～900 ℃, make the wire rod slow cooling again, when the wire rod temperature is chilled to 480～650 ℃, collect volume, thereby obtain described mother metal.
The present invention has following advantage and effect:
Have the following advantages with such scheme gained system nail and dedicated base material for cold rolling reinforced steel-bar with ribs: 1, physical dimension precision height, the surface quality of dedicated base material are good, can guarantee the stability of mother metal in the cold working process, to reduce the generation of industrial accident.2, the poker characteristic of dedicated base material is stable, is difficult for broken string in the operation of rolling, can significantly improve the qualification rate of cold rolled reinforcing steel bar with ribs performance, reduces production costs.3, the intensity rank of dedicated base material and complete in specifications can satisfy the cold rolled reinforcing steel bar with ribs that manufacturer produces varying strength rank and specification.4, the cold rolled reinforcing steel bar with ribs of producing with mother metal provided by the invention had both improved engineering construction state of the art and construction quality, had reduced raw-material consumption again, had reduced construction costs, createed considerable social benefit.
