摘要： The invention concerns an apparatus for studying quenching fluids and quenchability of materials in the form of testpieces 5, comprising a heating furnace, a means for introducing each testpiece into the quenching liquid and extracting the quenched testpiece, a quenching tank 20 containing the quenching fluid and a means for circulating the quenching fluid. According to the invention, the quenching tank 20 comprises an upper tank 21 and a lower tank 22 connected by a means 27 for organizing the circulation, the upper tank being provided with an immersed injector 40 formed by at least one circular array comprising a plurality of radial nozzles and connected to a pressurized fluid source 30, the upper part of the upper tank comprising a conduit 39 for returning the fluid to the pressurization means 30, the lower tank 32 comprising a separate pressurized fluid intake, which apparatus includes means for regulating the temperature of the fluid and means for measuring the speed of the fluid.
