Description

Technical Field

[0001] This utility model belongs to the field of quenching technology, specifically relating to a quenching device for processing round rods. Background Technology

[0002] Quenching is the core heat treatment process in round bar machining. It involves heating steel to a critical temperature (e.g., 840-860℃ for 45 steel), holding it at that temperature, and then rapidly cooling it (with water, oil, or air). This process causes austenite to transform into martensite or bainite, significantly improving hardness, wear resistance, and fatigue resistance. Quenching round bars requires precise control of heating temperature, holding time, and cooling rate: for large round bars, the holding time needs to be extended to ensure uniform austenitization. The choice of cooling medium must balance hardness and deformation risk (water cooling is fast but prone to cracking, while oil cooling is stable but inefficient). After quenching, tempering (e.g., high-temperature tempering at 550-600℃) is often performed to improve toughness and prevent brittle fracture. Process optimization includes ultra-fine grain refinement and control of carbide distribution to improve overall performance.

[0003] When the round rod processing quenching device is in operation, the existing technology cannot automatically pick up the round rod and send it to the quenching tank. It still needs to be transported manually, which greatly reduces the quenching efficiency and increases labor costs. At the same time, it cannot filter the quenching liquid, and impurities will enter the quenching tank, affecting the quenching quality. Utility Model Content
