Recently, Hanzhong Steel Company has made another good news. The No. 1 bar line successfully completed the first trial rolling of 20CrMnTiΦ30 round steel for gear steel, marking a solid step forward for Hanzhong Steel Company in the development of gear steel.
The 20CrMnTi round steel used in this trial rolling is mainly used in key parts such as general machinery and automobile gears and transmission shafts. With the vigorous development of the automobile industry, the market demand for gear steel continues to rise. To ensure smooth trial rolling, the R&D team combined the characteristics of its production line equipment to strictly control the smelting process of 20CrMnTi to ensure that every process is accurate and correct; repeatedly deduced the rolling parameter design, striving to achieve the best state, and finally formulated a set of scientific and efficient full-process process control solutions.
During the production process, the technical team stayed at the production line throughout the whole process and closely monitored the data of each key link. Faced with parameters such as rolling rate and upper cooling bed temperature, the technicians made dynamic adjustments according to the actual situation and did not miss any details that might affect the product quality. With a rigorous attitude and professional technology, the trial rolling work was successful on the first try. After testing, the mechanical properties, dimensional accuracy, and surface quality of the product all met expectations.
The successful rolling of Φ30mm 20CrMnTi round steel has enhanced the market competitiveness of Hanzhong Steel's high-quality bar brand and accelerated the successful implementation of the company's "million tons of high-quality wire rods" strategic layout.
