Technological Breakthrough (Sinosteel Xingji No-Stick Steel Collar Put into Operation)

At the end of October 2025, the domestic first "no-stick steel collar" jointly developed by Baowu Intelligent Maintenance and Sinosteel Xingji successfully entered service at a steel mill in Hebei. Adopting multi-alloy high-speed steel oxide glaze self-lubrication technology, the collar can automatically form an inert protective film to prevent steel adhesion. Its replacement cycle is nearly 3 times longer than that of traditional rolls, and the number of shutdowns for grinding is reduced by 55%, overcoming the steel adhesion problem in section steel rolling. It has laid out 16 invention patents.
