Abstract
The present invention is to provide a kind of methods using thermomechanical treatment production prestressed steel bar.Rod iron thermomechanical treatment is sequentially carried out equipped with oxide layer brush, electromagnetic induction heating furnace, spiral ribs roll, quenching sink and electric heating tempering furnace on rod iron by input roller, is pulled out by the rod iron of thermomechanical treatment with pull-out roll.High-quality using prestressed steel bar made of the method for the present invention, stability is strong, and metallographic structure is fine and close, and rigidity is uniform.Suitable for the method application processed as prestressed steel bar.
Description
Technical field
The present invention is to provide a kind of methods using thermomechanical treatment production prestressed steel bar that machinery field uses.
Background technology
It during rod iron processing spiral ribs, needs to heat rod iron, rolled threaded rib and quenching are with being tempered.It heats, quenches
Fire is different from tempering process, then directly affects the quality of rod iron.
Invention content
In order to improve the quality of prestressed steel bar, the present invention proposes a kind of using thermomechanical treatment production prestressed steel bar
Method.The technical issues of this method is by continuously processing, solving the processing of deformation prestressed steel bar.
Scheme is used by the present invention solves technical problem：
Oxide layer brush, electromagnetic induction heating furnace are sequentially equipped on rod iron by input roller, spiral ribs roll quenches sink,
Electric heating tempering furnace carries out rod iron thermomechanical treatment, is pulled out by the rod iron of thermomechanical treatment with pull-out roll.
Wire brush is housed in the oxide layer brush.
Good effect, high-quality using prestressed steel bar made of the method for the present invention, stability is strong, and metallographic structure is fine and close,
Rigidity is uniform.Suitable for the method application processed as deformation prestressed steel bar.
Description of the drawings
Fig. 1 is sequential organization schematic diagram of the present invention；
Fig. 2 is oxide layer brush configuration figure of the present invention.
In figure, 1. input rollers, 2. oxide layer brushes, 2.1. wire brushes, 3. electromagnetic induction heating furnaces, 4. spiral ribs rolls,
5. quench sink, 6. electric heating tempering furnaces, 7. pull-out rolls.
Specific embodiment
According to the figure：Oxide layer brush 2, electromagnetic induction heating furnace 3, spiral are sequentially equipped on rod iron by input roller 1
Rib roll 4, quenches sink 5 and electric heating tempering furnace 6 carries out rod iron thermomechanical treatment, passes through the rod iron pull-out roll of thermomechanical treatment
7 pull out.
Wire brush 2.1 is housed in the oxide layer brush.
The course of work:Wire brush is equipped in descale brush endoporus, by wire brush to rod iron surface brushing, removal oxidation
Layer, the rod iron gone after removing oxide layer are entered in electromagnetic induction heating furnace, 900-950 DEG C are warming up to, by the steel of heat distortion
Stick shuts out spiral ribs on spiral ribs roll, and then rod iron enters Cooling Quenching in quenching tank, and rod iron is made to be converted to martensite
Tissue enters in electric heating tempering furnace after the completion of quenching and is tempered, and the rod iron after tempering is pulled out by pull-out roll, becomes heat treatment
Prestressed steel bar afterwards.
Feature：
By the rod iron dense structure of deformation heat treatment, even structure, anti-shear ability is strong, big with grip of concrete, especially
The advantage for more having enhancing structure is used in building iron concrete.
