Definitions
- the invention relates to a method for the production of cold-worked, in particular cold-drawn, precision steel tubes, according to the preamble of claim 1.
- precision steel tubes according to DIN EN 10305 part 1 and 2 are considered in this context, standing standing in the operating state under high internal pressure, for example, cylinder tubes in the hydraulic or pneumatic field application.
- Such produced pipes are characterized in particular by narrow wall thickness and diameter tolerances.
- the starting product may be either a seamless hot-rolled or a hot-rolled strip produced by high-frequency induction welding (HFI welding).
- HFI welding high-frequency induction welding
- this pre-pipe which is referred to as a lump, is pulled to the required finished dimension (diameter, wall thickness) to the finished pipe.
- Steel grades include unalloyed high-quality steels up to E 355 as well as higher-strength grades up to StE 690.
- Hydraulic cylinders control motion sequences in many devices and machines that u. a. can also be used outdoors in the event of large temperature differences.
- the object of the invention is to provide a method for producing cold-finished, in particular cold-drawn precision steel tubes for use in particular as pressurized cylinder tubes, with a simple and cost-effective manner a largely ductile failure of the tube even at temperatures of up to -20 0 C can be achieved safely.
- a method is used in which the pre-pipe is finished in one or more passes, wherein prior to the finishing, the pipe is subjected to a tempering treatment and the steel pipe has the following chemical composition (in%):
- AI 0.020-0.060
- alloying elements depending on the required property profile, d. H. in particular according to the desired mechanical properties, and advantageously have the following contents (in% by weight):
- the tempering treatment itself consists of a classic hardening with subsequent tempering of the pipes. Aligned to the respective material austenitization is carried out at temperatures of about 910-940 0 C, followed by a quenching process forming a hardening structure.
- the quenching can be done on different quenching media, usually the quenching is done by means of water over a water shower.
- the cooling takes place, for example, in still air.
- the tempering treatment takes place, depending on the material at temperatures of approx. 540 - 72O 0 C.
- the advantage of the proposed method is the fact that a very uniform homogeneous structure with excellent toughness is produced by a tempering step before the finish train, which is essentially retained even after the finished draft of the pipe. Investigations showed that the values for the notch impact work at -20 ° C and a 50% shear fracture fraction in the DWT test are excellent at 80 J for transverse samples and 100 J for longitudinal samples.
- the final annealing is advantageously carried out in a temperature range of 500-700 0 C, wherein it should be ensured that the exact temperature setting in dependence on the material properties to be achieved, such. As strength, elongation at break and impact energy work, should take place.
- the material concept of the invention thus allows the operation of hydraulic cylinders in the temperature range to -2O 0 C safely.
