High strength, good heat resistance, good surface roughness of rolled material, high hardness, good wear resistance.
Compared with traditional ductile iron roll and high Ni-Cr roll, high-speed steel roll has higher wear resistance and higher single-pass over-steel volume, saving the roll change time, improving mill operating rate, reducing roll consumption and reducing Production costs, improve the overall efficiency of the factory.
Production of high speed steel rolls:
1, material procurement: the selection of high-quality high-speed steel materials, to ensure that the manufactured roll material has high hardness, toughness, crack resistance.
2.Outer circle turning: according to the size and accuracy requirements of the mill, the lathe is used for outer circle turning to complete the pre-process of the mill.
3.Aqueous solution quenching: Aqueous solution quenching is an important manufacturing process in the industry, which can reduce the dimensional error and loose defects of precision rolls.
4.High precision inner circle machining: On the precision lathe, high precision inner circle turning is carried out to ensure the accuracy and precision of the roll size.
5.Finishing and grinding: finishing and grinding the surface of the rolling mill to improve its surface finish and precision.
6.Laser processing: In the laser processing machine, according to the design drawing of the mill, the mill is accurately reduced to achieve the best profile and dimensional accuracy.
7.Gas quenching: The rolling mill is heated to the final state by the gas quenching process.
8.testing: The use of high-power microscope, scanning electron microscope, hardness tester and other testing equipment to test the rolling mill to ensure that its dimensional accuracy meets the design requirements.
In short, high-speed steel roller is a high-precision, high-tech product, with high wear-resistant, high-precision, high availability, high production efficiency advantages, its production process is fine and complex, requiring manufacturers must be equipped with strict manufacturing process, the use of high-quality materials and accurate advanced processing equipment, in order to ensure the production of high-speed steel roller to achieve the best performance.
