Abstract |
AB |
[EN] The method involves austenitizing the carbon steel (1) at a temperature above the austenitizing temperature and then cooling same by passing the steel through a bath (2) having a low volume of quenchant (21) so that a determinable amount of the bainite structure has formed in the bath with the quenchant on the overall steel structure. When the steel leaves the bath the quenchant residue is removed from the steel surface by a gas action and the remaining structural parts of the steel are converted into bainite in a subsequent isothermal tempering station (13) at the conversion temperature for bainite without any deflection of the carbon steel on passing through the isothermal tempering station until the bainite structure has completely formed inside the carbon steel. An independent claim describes a device for forming bainite or sorbite structure in carbon steel with an austenitizing station, a cooling bath with quenchant, an isothermal tempering station and a cooling station (17,18) wherein the tempering station forms a vertical tower so that the steel passes through sufficiently long enough for conversion of the remaining structure into bainite without deflection of the steel. |
