HSS Rolls, short for High-Speed Steel Rolls, are mainly utilized in hot and cold rolling processes across various rolling mills. They are favored for their exceptional wear resistance, heat crack resistance, and fatigue failure resistance.
High-speed steel rolls typically consist of high carbon, vanadium, molybdenum, tungsten, and chromium elements. These elements contribute to the rolls’ high hardness, wear resistance, and hot hardness properties that allow them to operate effectively under high temperatures and pressures.
The manufacturing process of high-speed steel rolls is crucial and involves casting, heat treatment, and machining steps. The casting process ensures a uniform internal structure of the roll; heat treatment enhances its hardness and toughness; while machining guarantees dimensional accuracy and surface quality.
Due to their superior performance characteristics, HSS Rolls find extensive use in the steel industry – particularly in rolling high-strength steel alloys like stainless steel and silicon materials.
