摘要： A method continuously creates a bainite structure in a carbon steel, especially a strip steel by austenitizing the carbon steel; introducing the austenitized carbon steel into a bath containing a quenching agent; adjusting the carbon steel to the transformation temperature for bainite and maintaining the transformation temperature for a certain period of time; and then cooling the carbon steel. The carbon steel stays in the bath until a defined percentage of the bainite structure relative to the total structure of the carbon steel has formed. Residues of the quenching agent are removed from the surface of the carbon steel by blowing the same off when the carbon steel is discharged from the bath, and the remaining structure components of the carbon steel are then transformed into bainite in an isothermal tempering station without deflecting the carbon steel at all.

摘要： Ferritic nitrocarburized surface treatment of cast iron brake rotors providing oxidation resistance, good braking performance and absence of distortion. Machined brake rotors are pre-heated, then immersed into a high temperature molten nitrocarburizing salt bath for a first predetermined dwell time. After removing the brake rotors from the nitrocarburizing salt bath, the brake rotors are directly immersed into an oxidizing salt bath at a lower temperature than the nitrocarburizing salt bath so that the brake rotors are thermally quenched. After a predetermined second dwell time in the oxidizing salt bath, the brake rotors are removed therefrom and further cooled to room temperature, either by water application thermal quenching or slow cooling in air. A fixture provides stable holding the brake rotors with a minimum of contact during placement in the salt baths.

摘要翻译： 铁素体氮碳共渗表面处理铸铁制动转子提供抗氧化性能，良好的制动性能和不变形。 将加工的制动转子预热，然后浸入高温熔融的氮碳共渗盐浴中达到第一预定停留时间。 在从氮碳共渗盐浴中除去制动转子后，将制动转子直接浸入低于氮碳共渗盐浴的温度的氧化盐浴中，使制动转子热淬火。 在氧化盐浴中经过预定的第二停留时间之后，通过施加水的热淬火或在空气中缓慢冷却将制动转子从中除去并进一步冷却至室温。 固定装置在放置在盐浴中时能够以最小的接触稳定地保持制动转子。

摘要： The method comprises effecting the solidification of the metal in a continuous casting ingot mould constituted by two cooled rolls (2) rotating in opposite directions and disposed in confronting relation so as to define a casting space therebetween, continuously extracting from the ingot mould a solidified steel strip (3), and, below the ingot mould, subjecting the strip to a quenching medium (6) so as to cool it sufficiently rapidly to prevent formation of austenite. This medium may be formed by a quenching bath placed in a container (4) disposed under the rolls (2) and having a bottom provided with an opening (5) for the passage of the solidified strip (3). The quenching medium may also be formed by an inert gas in the liquid state blown onto the product by nozzles. The steel strips obtained are easier to shear and coiled at the output end of the casting line owing to the absence of martensite in the ferritic matrix.
