Successful trial production of high-strength wear-resistant steel NM360
First of all, the raw materials and smelting technology used in the trial production were strictly controlled to ensure high-quality product output. The raw materials were carefully discussed and provided with high-quality iron ore and alloy materials, choosing suitable pig iron and steel scrap to ensure the raw material stability and controllability. During the smelting process, the tap control technology was adopted to adjust the tapping temperature of steel. This has effectively improved the stability of the steelliquid, and improved the smelting quality of high-strength wear-resistant steel NM360.
Secondly, the inner structure of high-strength wear-resistant steel NM360 was carefully adjusted during the trial production process. During the preliminary and intermediate rolling processes, conventional rolling and accelerated cooling technologies were adopted to adjust the microstructure and grain size of the steel. The technology has changed the ferrite population from random to middle crystal state, and fine grains, so as to improve the tensile strength and wear resistance of high-strength wear-resistant steel NM360.
Thirdly, special technologies were adopted to optimize the surface hardness of the steel. Through long-term research, a reasonable quenching medium and heating temperature were determined to realize the quenching process of high-strength wear-resistant steel. After the quenching process, different surface treatments like tempering and polishing were applied to the steel. The combination of these surface treatments can significantly improve the wear resistance and surface hardness of the steel, without affecting its tensile strength.
Shows a typical microstructure of high-strength wear-resistant steel NM360, which can be seen that the microstructure is fine and compact, and the distribution of ferrite is balanced.
Through this production trial, high-strength wear-resistant steel NM360 with excellent performance and quality has achieved. has achieved. The excellent mechanical properties and chemical composition of the steel make it an ideal material for a variety of field applications, such as shipbuilding, oil and gas exploration, and heavy machinery parts. In addition, the production process has been greatly improved and the efficiency of the whole production process has been greatly improved.
In summary, through careful research, careful preparation, and precise adjustment, the successful trial production of high-strength wear-resistant steel NM360 has achieved, providing an ideal product for the production of heavy-duty engineering products. It is hoped that this success can be widely used in the steel industry in the future.
