Abstract

A method for the air-hardening of steel casting, such as side frames and bogies bolsters comprises heating above the critical point, exposure in the heat furnace and cooling. At that cooling is carried out in three stages: first on the pallet disposed on the furnace hearth, which is exposed from the furnace, the second - on the pallet, put down from the extended furnace hearth, on the still air, and the third - without the pallet on the shop floor, on the still air until the final cooling, that is, to the forming of sorbitic structure to provide the necessary physical and mechanical properties.
