|General Knowledge on “Metal Extrusion Fabrication”|
Cold extrusion means, at room temperature, with the tensile reinforcement force more than the original steel yield strength tensile stress, to let metal become reinforced plastic deformation in order to improve the yield strength of metal reinforced and to save material.
The plastic deformation process after neck specimens into a tensile test. When the elongation performance of samples to a stable sectional dimension necking section along the specimen continues to expand, until the whole sample become necking state. Necking occurs in the yield point stress decreases sharply stage. During cold drawing specimen under tensile force remained unchanged.
Cold extrusion concept
In order to save steel, steel for the purpose of improving the yield strength, with more than the yield strength and less than the ultimate strength tensile stress in tensile reinforcement, the plastic deformation of the practice that cold drawing.
The first cold extrusion. Take a reinforced by applying tensile stress of the steel bar cold drawing deformation may occur. With the tensile stress increased, reinforced internal tensile stress increases. When the yield point reinforced internally generated tensile stresses exceed reinforced with after cold drawing, stop, remove the load. This time we can see, steel has produced plastic deformation.
Second cold extrusion. Re applied tensile stress, the reinforcing bar tension to failure, changes of plastic steel, plastic small, high hardness, the strength of the reinforcing bar is improved, this phenomenon is called “deformation hardening”.
After more than two process of cold drawn steel production is completed.
Cold extrusion control
1) cold stress control condition:
For the reinforced II, III, IV grade steel and 5 steel, in after cold drawing, make use of prestressed reinforcement, with cold stress control. But after cold drawing steel after inspection, the maximum cold pull rate exceeds the specification values, and then to the mechanical experiment.
2) drawn rate measurement control requirements:
Control of steel bar cold to cold pull rate, control values to be determined by the test. Experimental determination of requirements: Determination of the same batch with furnace specimens, not less than 4, each specimen by the rules and regulations of cold stress determination corresponding cold pull rate, and take the average of the specimen as the furnace of the number of actual cold drawn steel ratio. If the steel strength high, average cold pull rate is less than 1%, in the cold drawn steel, are still on the 1% cold pull rate control.
3) furnace batch of different cold extrusion control:
For hybrid, confuse reinforced, furnace batch of cold, can not control the rate of cold drawing, but also to cold drawing a plurality of connection, each cold pull rate and the control stress must conform to the rules and regulations.
4) cold extrusion speed control:
To make steel fully deformation, we should properly control the cold drawing speed, generally 0.5 – 1 is appropriate. At the same time requirements, drawn to the specified shall force and cold drawn ratio, then stopped to pull 2 – 3 after the end of cold drawn, and then relax bar, to give the steel fully deformation time.
5) drawing extrusion method:
Cold extrusion only when the rate of cold drawn or cold stress control called the single control, during cold drawn rate and cold stress at the same time the application, called the dual control. Using a single control, simple and convenient construction. But for the reinforced material is not uniform, not possible by root test (by root test, labour and material consuming, not possible to do so, some of the same reinforced cold pull rate are not the same) cold drawn quality can not be guaranteed. Double control method can avoid these problems. Cold, to control the stress has been reached, the tension rate did not exceed the allowable value, can be considered qualified. However, if the tension rate has been reached, and cold stress is not up to the control stress, the steel to reduce the intensity of use. For prestressed must adopt the double control method.
- cold drawn before should first cold tension ability and reinforced cold drawing equipment check whether to adapt, does not allow the overloading of the machine drawing.
- should always check the cold ground anchor is stable, windlass, signal device, wire rope, fixture, pulley group is normal, should be excluded from the hoister slip in cold drawn before operation, signal, mechanical failure, fixture, or wire rope fracture and other unsafe factors.
- the cold drawing process, should obey the unified command, thought the operation personnel to concentrate, hoist the driver to start and stop signals according to the provisions of.
- cold site should set the alert zone at both ends of the ground anchor outside, and should be installed fence and warning signs, cold pull both ends of the protective equipment to be installed, to prevent the reinforced bar or detachment, fixture flying out to hurt people. No not standing in the cold wire at both ends, or across, touch is cold drawing processing steel. The operating personnel must be in the operation of left outside the reinforced 2m.
