Pankov, S. Nagornov, S. Kuz'min, I. Cherepennikov] Conclusions: 1. A significantly higher uniformity of properties over the height of a lengthy component is achieved when it is quenched in a boiling layer with water injected onto its surface than after conventional quenching. In this case, the standard deviation of hardness and the warping of such a component are also appreciably lower. 2. The proposed method makes it possible to improve the quality of quenching, since no wetting of the boiling layer is required on the whole, the layer does not deteriorate in service, and no channels form in it. Use of liquid injected directly onto the component tends to reduce consumption of coolant, which is completely evaporated. The boiling layer remained dry on the whole, and its hydrodynamics is not disturbed. 3. The variation in the consumption of coolant over the height of the component and the subsequent reduction in aeration intensity make it possible to cool the component in precise conformity with its production thermograms; this improves the quality of the quench. Nonuniformity of component cooling with respect to its height is eliminated in this case.
