The animation below shows the heat treatment simulation of an axle shaft using DANTE.
Part: 1 m long, 34.93 mm diameter axle shaft with a flange on one end and a 35-tooth spline on the other end.
Process: Inductor dwells at flange end for 9 seconds and then begins to move up the shaft at 12 mm/s for 1.5 seconds. The inductor slows to 8 mm/s and the spray begins at the flange. The inductor continues up the shaft, with the spray following, until the inductor is shut off as it nears the spline.
The animation below shows the heat treatment simulation of a large landing gear using DANTE.
Part: 3 m long landing gear made of 300M steel.
Process: The landing gear is lowered into an oil tank, after being heated in a pit furnace, at a rate of 4 m/s. The landing gear then sits, fully immersed, in the oil until the phase transformations have completed.
The animation shows contact gear stresses, with the residual stress predicted from a DANTE heat treatment simulation, considered during the analysis. Stresses from forming operations can also be used as a starting condition for the DANTE heat treatment simulation.
The animation shows the use of DANTE heat treatment simulation software in modeling a low pressure carburization process of a high alloy steel with strong carbide forming elements (e.g.; Cr, Mo, V). The animation shows the prediction for carbon in the austenite matrix (left), carbon in carbide form (middle), and a relative carbide size (right). There is a total of 34 boost/diffuse steps, plus a final diffuse to help dissolve the carbides and achieve the correct case depth.
Animation shows the top view of a DANTE heat treatment simulation of a thin ring undergoing a 2-bar high pressure gas quench. There is a directional gas flow from bottom to top; simulating a front to back gas flow in the high pressure chamber. The distortion has been magnified 50X to clearly show the movement created by the nonuniform cooling and the resulting out of round distortion.
Simulation of DANTE controlled gas quenching process of a ring with nonuniform gas flow (from bottom to top of screen) using DANTE heat treatment simulation software. The process reduces distortion of steel components during gas quenching by controlling the quench gas temperature, which controls the thermal and phase transformation gradients in the part. Nonuniform gas flow is identical to the animation above (HPGQ Simulation of Thin Ring with Directional Gas Flow)
Animation of a press quenching operation of a steel gear using DANTE heat treatment simulation software.
Animation of an oil quenching process of a gas carburized bevel gear. The gear has 40 teeth with an 8 inch outer diameter, a 1.5 inch bore, and an axial length of 4 inches. The entire gear is gas carburized to an effective case depth of 0.028 inches and cooled to room temperature after carburizing. The part is then heated to form austenite, transferred from the heating furnace to the quench tank, and quenched in oil. Notice the amount of movement that the bevel undergoes. That is why these types of gears are generally press quenched.
Animation of a steel cube subjected to 150 austenitizing-quenching cycles. It is clear the cube is turning into a sphere. The inset shows a photograph of an actual steel cube subjected to several hundred austenitizing-quenching cycles.
