Last month we first put forward to use PTRW6 ultra-fine grain wear-resistant steel for extrude parts. But where does this material comes from?
Recently, in the wonderful sharing of our company’s technical director, Mr. Wang, at the industry summit, a latest research and development achievement of ultrafine grain modification technology based on metal materials was presented for the first time, attracting widespread attention from the industry.
Traditionally, key parts, such as for extruder screw element often require the materials with high metal strength and good toughness. Generally speaking, the microstructure of metallic materials is composed of the matrix and the strengthening phase. To enhance the performance of components in use, the conventional approach is often to increase the volume fraction of the strengthening phase. However, this approach can easily lead to an uneven distribution of the strengthening phase, thereby affecting the balanced performance of the overall material.
Especially in practical industrial application, under the premise of how to control the cost, at the same time guarantee the material has high strength, hardness, excellent wear and corrosion resistance, and implement the cooperative optimization of several key indicators and the metal material design and the process is very stringent requirements are put forward.
Relying on the domestic top universities scientific research strength and technology accumulation, our technical team successfully developed and applied to the following two core technologies:
first, the super fine crystal modification technology – by severe plastic deformation, effectively breaking the strengthening phase state of aggregation, achieve its evenly dispersed, gain sub-micron grain and nano strengthening phase structure. This technology significantly optimizes the metallic properties of the material, enhancing the performance of screw elements by 50% to 150%, and demonstrates outstanding performance in terms of strength and toughness matching as well as wear and corrosion resistance.
Second, the micro alloying technology, aiming at the special working condition of the extruder market, we had a strict control on the material purity, and accurately adjust the type and content of trace alloy elements, to the best matching state. Compared with conventional materials, this technology has significantly increased the service life of the extruder screw elements by 50% to 100%, while maintaining good economic performance.
In conclusion, the combined application of ultrafine grain modification technology and microalloying has provided a solid support for the manufacturing of our company’s high-end screw components and also brought new possibilities for the performance upgrade of the entire industry.
