In recent years, research and development of specialized alloy rolling equipment have continued to gain momentum, becoming a critical support for meeting the demands of aerospace material processing. As the aerospace industry increasingly raises its requirements for material performance, traditional processing methods have become inadequate to meet the precision-forming needs of special alloys such as high-temperature alloys and titanium alloys. Domestic research institutions and enterprises, through technological innovation, are driving the development of rolling equipment toward higher precision, greater efficiency, and智能化 (intelligentization).

For example, China Metallurgical Beijing Jingcheng Ruixin Long-Steel Engineering Technology Co., Ltd., in collaboration with universities, has developed a semi-continuous rolling process consisting of a two-roll reversible cross-moving mill and a continuous rolling line, specifically addressing the challenges posed by special alloys—namely their high resistance to hot deformation and narrow temperature ranges. This process also incorporates the concept of constant-temperature rolling. By precisely controlling the rolling temperature and deformation amount, the company has achieved “one-pass production” of titanium alloy bars and wires, increasing the weight per coil from 70 kg to 200 kg, raising the yield rate to 81.4%, and reducing processing costs by 40%. Meanwhile, Northeastern University has proposed a warm-roll hot rolling technology for TiAl alloys. By using electromagnetic induction heating to compensate for temperature drops in the rolls, this technology effectively solves the problem of cracking during rolling, thereby making it possible to roll these alloys without protective casings.

Moreover, the successful domestication of the three-roll reducing and sizing CNC rolling mill has resolved the “bottleneck” issue associated with imported equipment. Its high-synchronization drive system and micron-level die adjustment technology enable special alloy bars to achieve dimensional accuracy meeting international standards and significantly improve surface quality. The research and development and application of this equipment not only accelerate the localization of aerospace material processing but also provide a solid technological foundation for the manufacturing of high-end equipment.
