The device of the study of hardening fluids and quenchability of materials

摘要

P the invention relates to a device for the study of hardening fluids and quenchability of materials, in the form of test pieces 5, comprising a heating furnace, a means of the introduction of each test piece in the quenching liquid and extraction of the test piece quenched, a quenching tank 20 containing the quenching fluid, and a means for circulating the quenching fluid. & br / according to the invention, the quenching tank 20 comprises an upper container 21 and a lower tank 22 connected by a means 27 for the circulation, the upper tank being provided with an injector immersed 40 formed of at least one circular ramp comprising a plurality of nozzles radial and connected to a source of fluid under pressure, 30, the upper part of the upper tank comprising a pipe 39 of the flow of fluid towards the means 30 for applying pressure, the lower tank 32 comprising a separate supply of fluid under pressure, a means for regulating the temperature of the fluid, and means for measuring the speed of the fluid. & br / (see appended drawing in bopi) & br / & & br / / p
