Technical Field

[0001] This utility model relates to the field of high-speed steel roll production technology, specifically to a high-speed steel roll quenching and cooling device. Background Technology

[0002] High-speed steel rollers are rollers made of high-speed steel and are widely used in industrial environments requiring high wear resistance and high hardness. High-speed steel (HSS) is a special alloy steel with excellent cutting and wear resistance, and it can maintain its hardness under high temperature conditions, making it suitable for the manufacture of cutting tools and high-load tools.

[0003] Existing high-speed steel rollers often need to be cooled after quenching, and this cooling is mostly done by quenching oil. The current cooling method is that personnel use clamps to place the high-temperature high-speed steel rollers after quenching directly into the oil tank, and then take the high-speed steel rollers out after they have cooled to the required temperature.

[0004] However, in practice, the metal shavings and other impurities generated during quenching on the high-speed steel rollers remain in the quenching oil. When personnel discharge the waste oil, these shavings remain in the cooling tank, requiring a significant amount of time and effort to clean them. Therefore, the existing high-speed steel roller quenching and cooling devices still have certain shortcomings in practical use.

[0005] In conclusion, it is necessary to invent a high-speed steel roller quenching and cooling device. Utility Model Content
