Abstract:

1. The controlled atmospheres obtained during the combustion of natural gas in the prototype furnace with fluidized bed at α≤0.45 sharply reduce oxidation and decarburization during the heating of alloy steels to 900-1000°C. In a carefully controlled furnace no decarburization of the surface layer takes place. 2. The heating of steels takes place in a fluidized bed at a considerably higher rate than in an electric furnace so that the heating time for hardening decreases in a ratio of 12:1 and for tempering in the ratios 8:1. 3. The hardening ability of a fluidized bed is the same as that of oil. 4. Mechanical properties and hardness of 18Kh2N4VA and 40KhNVA steels heat treated in a fluidized bed are stable and meet the specified requirements. 5. High-speed heat treatment in a fluidized bed without oxidation or decarburization of parts is recommended for use in industry. © 1972 Consultants Bureau, a division of Plenum Publishing Corporation.
