  • Patent number: 9458519
    Abstract: A process and apparatus for quenching a metal workload from an elevated heat treating temperature are disclosed. The process includes the step of flowing a vegetable oil quenchant over the metal workload to provide a cooling rate sufficient to transform the metal substantially completely to a desired second phase comprising martensite, bainite, pearlite, or a combination thereof within a preselected time period. The apparatus includes a quenching chamber that has a base, an upper housing, a door, and an associated actuator for opening and closing the quenching chamber. The apparatus also includes a vessel for holding a volume of a vegetable oil quenchant, means for conducting the vegetable oil quenchant from the vessel to the quenching chamber, and means disposed in the quenching chamber for flowing the vegetable oil quenchant over a metal workload disposed in the quenching chamber.

  • Patent number: 8784575
    Abstract: A method for carbonitriding a steel part arranged in an enclosure maintained at a reduced internal pressure, the part being maintained at a temperature level, comprising an alternation of first and second steps, a carburizing gas being injected into the enclosure during the first steps only and a nitriding gas being injected into the enclosure only during at least part of at least two second steps.

  • Patent number: 7118634
    Abstract: The invention relates to a low-pressure carburising method comprising alternating low-pressure enrichment steps and diffusion steps in the presence of a neutral gas. During the enrichment steps, an enriching gas and neutral gas mixture is used, the proportion of the neutral gas being between 5 and 50% by volume of the enriching gas. The enriching gas can be, for example, acetylene (C2H2).

  • Publication number: 20060157169
    Abstract: A method for quenching a steel load by flowing of a gas at the load level via gas moving means. The moving means are controlled to have the gas flow at the load level at a speed which varies according to a speed profile, at least a portion of which comprises, successively, a plateau at a first speed and a plateau at a second speed greater than the first speed.

  • Publication number: 20060048868
    Abstract: A rapid cooling method for metal parts, using a pressurized cooling gas, characterized in that the cooling gas comprises one (or several) principal gas(es) absorbing infra-red radiation, selected in such a way as to improve thermal transfer to the part by combining radiative and convective transfer pheonomena in order to optimize the convective transfer coefficient.
