Increased Productivity Combining C/C Fixturing and LPC

Carbon/carbon and graphite materials are used in a variety of applications throughout the high temperature furnace industry. Entire vacuum hot zones are manufactured from these materials as well as individual components such as insulation, lining materials, nozzles, fasteners and hearth supports. Fixtures and grids are also commonly manufactured from these materials and can offer a […]

Heat Treat 101: A Primer

Gears play an essential role in the performance of many products that we rely on in our everyday lives. When we think about gears, we generally separate them into two categories: motion-carrying and power transmission. Motion-carrying gears are generally nonferrous or plastics, while load-bearing power transmission gears are usually manufactured from ferrous alloys. The focus […]

Vacuum Carburizing Large Gears

Throughout the machining process, great care is taken to achieve and maintain critical dimensions. The gears are then handed over for heat treatment. Exposing the parts to a high temperature environment, changing the material chemistry, and rapidly cooling in oil to harden is necessary to produce the high strength and long wear life expected in […]

Tooth-by-Tooth Induction Hardening of Gears (and How To Avoid Some Common Problems)

Tooth-by-tooth induction hardening of gears is a complex process. Variations of any of kind may be sufficient to cause the process to run out of control and produce gears that are out of specification. Since heat treating occurs late in the production cycle, process failure is an expensive proposition. This article highlights some of the […]

Flame Hardening Gears

Long gone are the days when a machine operator sat in a dark corner of the shop staring at the cherry red glow of a gear being flame hardened. Typically the “craftsman” would wear dark welding glasses and make the decision that the color looked good just before the water spray quench completed the hardening […]

Heat Treatment of Large Components

Large gear components can be offered in many applications such as marine, wind power, steel rolling mills, power plants, transportation, railroad, aircraft, cement crushers, mining, and oil industry applications. There are three important surface hardening methods, as seen in Figure 1, used to improve and expand the technical use of gear components. Design and material […]

Advantages of Induction Hardening with No Soft Zone on Large Bearings

Large bearings are required to carry large axial and radial forces and their resulting torques. Typical applications include general machinery and construction equipment, as well as onshore and offshore energy technologies. These diverse applications have one thing in common: their components are highly stressed mechanically, and are therefore induction hardened to increase their dynamic strength […]
