One Minute Mentor: Plasma Nitriding Equipment

Cold-walled (double-walled water-cooled) systems were the first generation of plasma nitriding furnaces. This technology is also a vacuum-based process but employs the principle of glow discharge to provide energy for heating and nitriding at one time. Therefore, the independent control of the temperature stability and the nitriding intensity is not possible because both processes are using the same energy source—the plasma.

The hot-wall plasma nitriding furnaces, the next generation of cold-wall ion nitriding systems, are mainly used and built now. This system ensures optimal nitriding quality by fulfilling the highest demands on temperature and nitriding process control. The big advantage of this technology is the separation of the control of the heating and the plasma nitriding parameters. The heating and temperature control of hot-wall plasma nitriding furnaces is realized by several independent heating/cooling zones, which guarantees optimal temperature homogeneity

Seco/Vacuum awarded nine-furnace contract

Seco/Vacuum, Meadville, Pa., announced it has secured a record-breaking contract for nine furnaces in June. The order includes three Vector vacuum Furnaces and six tempering furnaces, along with necessary auxiliary systems, marking a significant expansion for a returning heat-treat partner that already operates twelve Seco/Vacuum furnaces across North America.

The new furnaces are part of the heat-treater’s strategic shift from atmospheric heat treatment to vacuum processes. This transition aims to modernize their facilities, offering cleaner, safer, and more cost-effective operations. Vacuum processes also allow for finer control and reduce the carbon footprint, aligning with contemporary environmental standards.

The Vector® furnaces, known for their versatility in heat-treating processes like hardening, tempering, and brazing, will primarily be used for hardening due to their high-pressure gas quench capabilities. These furnaces ensure high uniformity and consistency in heat-treated parts, with enhanced batch processing speed and reduced energy and gas usage.

The accompanying Tempering Furnaces, designed for efficient atmospheric tempering, feature convection heating for faster process temperatures and smoother workflow integration, crucial during the often-congested tempering stage.

To support the intensive hardening cycles of the Vectors, six tempering furnaces were chosen to maximize throughput and efficiency. Each furnace, both vectors and temperers, are front-loading with a capacity of 3,300 lbs and dimensions of 36 x 36 x 48 inches.

The full modernization will require a temporary shutdown of existing operations. Seco/Vacuum will mitigate downtime by also acting as the general contractor, overseeing the installation of furnaces, systems, and necessary infrastructure, ensuring a swift resumption of operations with new capabilities.

One Minute Mentor: Gas Nitriding Equipment

Gas nitriding and nitrocarburizing can be processed in horizontal or vertical chamber furnaces with refractory insulation. However, to allow a quick change of the atmosphere and to avoid influences resulting from previous processes in the same furnace, retort furnaces are preferred.

To enable an acceptable production capacity, large vertical retort furnaces are used. Figure 23 shows a schematic sketch of a vertical retort furnace with a compensator for sealing against atmosphere. Nowadays large horizontal retort furnaces are also used. Horizontal retort furnaces of different size and execution are preferred for nitrocarburizing processes. Figure 24 shows a schematic of a typical horizontal retort furnace. Similar to the vertical execution, a good circulation of the process gas is needed to get uniform results, which can be reached by the use of a muffle and a high circulation rate. Indirect cooling is performed with an external cooling fan, blowing cold air along the retort. Other designs allow direct cooling of the process gas with an external heat exchanger.
