High-carbon high-speed steel roll (HSS roll) is the hot-roll material with the shortest appearance, the fastest development, and the widest application prospect.
High-speed steel, also known as wind steel or front steel, means that it hardens even when cooled in the air when quenched and is sharp.
Our high-speed steel rolls are widely used in:
Finished frame (high-speed steel roll), front frame (high-speed steel roll), slitting frame (high-speed steel roll), pre-slitting frame (high-speed steel roll).
High-speed wire mill pre-finishing unit. Finishing Mill for Hot-rolled Narrow Strip Mill.
Finishing stands for spring flat steel mill and small section mills such as angle and channel steel.
It is complex alloy steel with carbide-forming elements such as tungsten, molybdenum, chromium, and vanadium. The total amount of alloy elements reaches about 10%~25%.
Advanced Manufacturing Processes and Implementation Standards
Product design → roll billet design → roll billet manufacturing → roll billet acceptance → annealing → rough turning → ultrasonic flaw detection → high temperature quenching → low temperature tempering → ultrasonic flaw detection → finishing → ultrasonic flaw detection → roll body grinding → roll number → inspection → cleaning → packaging→ storage → shipments→ inspection → use and maintenance →exchanged → improvement of design.
It can be seen from the flow chart that roll manufacturing forms a closed-loop system from product design, production manufacturing, use and maintenance, and improvement design, and the quality of roll is constantly improving.
Standards for roll manufacturing and testing:
First, production must be organized according to product drawings and technical requirements agreed upon by both suppliers and consumers.
The main standards are:
GB/T 13313-2008 Roll Shore and Ribbon Hardness Test Method
GB/T 1503-2008 Cast Steel Rolls
A. Inspect the dimensions and surface quality of each part individually;
B. Perform three ultrasonic flaw tests one by one;
C. Carry out hardness tests one by one;
D. The depth of the hardened layer on the roll body is determined by the manufacturing process.
