Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to an oil blowing device for a continuous furnace for metal surface treatment. Background Art

[0002] Quenching is a metal heat treatment process that changes the structure and performance of a metal material by rapidly heating it to a suitable temperature and then rapidly cooling it. Quenching allows the metal material to gain higher hardness, strength and wear resistance while maintaining a certain toughness.

[0003] Quenching oil is a process oil used as a quenching medium. The cooling capacity of oil in the range of 550-650℃ is insufficient, and the average cooling rate is only 60-100℃ / s, but in the range of 200-300℃, the slow cooling rate is very suitable for quenching. The oil is used for quenching alloy steel and small-section carbon steel, which can not only obtain satisfactory hardenability and hardenability, but also prevent cracking and reduce deformation.

[0004] However, after the product is quenched, a large amount of quenching oil will remain on the surface of the workpiece. Some of it will drip naturally during the transmission process, and most of it will be carried out of the oil tank along with the workpiece and transmission parts, resulting in a waste of quenching oil and thus an increase in production costs.
