Description

Technical Field

[0001] This utility model belongs to the field of metal heat treatment technology, and specifically relates to a metal heat treatment quenching furnace. Background Technology

[0002] Quenching is a heat treatment process that involves heating steel to above its critical temperature, holding it at that temperature for a certain time, and then cooling it at a rate greater than the critical cooling rate to obtain a non-equilibrium microstructure dominated by martensite (or, depending on the need, bainite or single-phase austenite). Traditional quenching involves directly immersing the metal material or mold in water with tongs and removing it with tongs after a certain time, but this method is quite cumbersome.

[0003] Patent application number 202320136571.2 discloses a metal heat treatment quenching furnace lifting fixture, belonging to the technical field of quenching lifting fixtures. It includes a U-shaped base with metal storage hoppers on both sides. Grooves adapted to the metal storage hoppers are formed on both sides of the base. Multiple through holes are formed on the base and the two metal storage hoppers. Two protruding plates are fixed to the top of the base. A connecting piece is provided above the base. Two limiting blocks are fixed to both sides of the base. Each limiting block has a sliding groove, and a connecting rod is provided in each groove. A locking block is fixed to the end of each connecting rod, and a first spring is sleeved on each connecting rod. This metal heat treatment quenching furnace lifting fixture is easy to adjust and improves efficiency.
