Product Description

Product Introduction:
The high-speed steel roll material contains high alloy elements such as vanadium, tungsten, chromium, molybdenum, niobium, etc. The types of carbides in the roll structure are mainly MC type and M2C type. Compared with ductile iron rolls and high-nickel-chromium rolls, the single-groove (time) steel passing is higher, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, reduces production costs, and improves the overall benefit of the factory.
1. High-speed steel rolls have good thermal stability, and the roll surface has high hardness and good wear resistance at rolling temperature.
2. The high-speed steel roll has good hardenability, and the hardness hardly decreases from the surface of the roll body to the inside of the working layer, thus ensuring that the roll has the same good wear resistance from the outside to the inside.
3. During the use of the high-speed steel roll, under good cooling conditions, a thin and dense oxide film is formed on the surface of the roll body. This uniform, thin and dense oxide film can exist for a long time without falling off, making the high-speed steel roll wear-resistant. Sex is significantly improved.
4. The high-speed steel roll material has a large expansion coefficient and good thermal conductivity. While the roll wears a small amount of the groove during the rolling process, the hole shape continues to become smaller due to the expansion of the high-speed steel material itself. Therefore, the high-speed steel roll is rolling. During the rolling process, the change of the rolling groove is small, and the consistency of the pass size is maintained for a long time, especially when rolling bars or rebars, it is more conducive to control the negative tolerance of the rolling material.
5. Since the core of the centrifugal casting high-speed steel roll is made of alloy ductile iron material, the strength of the roll neck is high.

Product Application:
High-speed steel has only been used as a roll material for more than ten years. The reason why high-speed steel rolls are suitable for both plate and strip mills, wire and bar mills, and has achieved remarkable results is that high-speed steel has high The high wear resistance and hardenability, especially the red hardness at high temperature, make high-speed steel more suitable for use as a manufacturing material for rolls. At present, high-speed steel roll series products are widely used in:
1. High-speed bar pre-finishing stand, finished product stand, finished product pre-rolling stand, pre-slicing stand, slitting stand of bar rolling mill
2. High-speed wire rod mill pre-finishing mill
3. Hot rolling narrow and medium wide steel rolling mill finishing line
4. Finishing stand of spring flat steel mill and small section steel mills such as angle steel and channel steel
