Abstract:

1. Carburizing with combustion of natural gas in a fluidized bed with a stationary catalyst and air input coefficient α<0.25 is not possible because the GIAP-3 catalyst is deactivated by soot. When α=0.26-0.29 the carburizing capacity of the atmosphere is insufficient to carburize carbon and alloy steels. 2. In order to increase the carbon potential of the atmosphere with α=0.26-0.29, 15-25% gas-carburizer must be added. 3. The carburizing time for a case depth of 1.0-1.2 mm is 1.5 h at 950°C with the addition of raw natural gas. The high rate of the process is due to the rapid heating and more favorable conditions of the surface for carburizing in a fluidized bed. © 1972 Consultants Bureau, a division of Plenum Publishing Corporation.
