Abstract:In order to improve the control precision of narrow hardenability band for gear steel, the target values and their precision range of component control were determined, and the computer control model of alloy addition and the rule base of composition adjustment were established, and hardenability prediction models were developed on the basis of incremental neural network. These control technologies of narrow hardenability band for gear steel were applied for the gear steel of 20CrMnTiH, the results show the reasonable hardenability band was obtained, the ratios of hardenability band ≤4HRC of J9 and J15 reached 93.3% and 89.2%, respectively, ratios of hardenability band ≤6HRC reached 99.3% and 98.4%, respectively.
