NGC Gears, a manufacturer of wind power gearboxes, has completed the installation of two additional Endothermic generators from a manufacturer with North American locations. 

UPC-Marathon, a Nitrex company, installed the Endo generators at NGC Gears‘ its new facility in Jinhu, China. This acquisition brings the total of generator sets to five since 2022, collectively generating an impressive 800 m³/h (22,252 ft3/h) capacity of Endothermic gas supplied to carburizing and hardening furnaces used for processing various gear components. The latest installations in February and March of 2024 support the heat treating operations of the company’s wind energy gearbox production.

NGC’s decision to expand capacity is in response to the growing demand for wind power solutions in China and globally. The new Endothermic gas generating systems will significantly enhance the company’s production capabilities, enabling NGC to meet increasing market needs with greater efficiency and reliability.

EndoFlex offers precise control of production media to the carburizing and hardening environments, leading to higher quality gear production with improved longevity and performance. The result is improved carburizing and hardening processes, higher-quality hardened gears, reduced operating costs, and increased efficiency, as well as immediate cost savings through reduced electricity and gas consumption and minimized waste.

Johnny Xu, general manager at UPC-Marathon China, shared, “The latest EndoFlex investments align with NGC’s development of low-consumption, high-efficiency gearbox products for large-scale onshore and offshore wind turbines.”

Today’s tips come to us from AFC-Holcroft, covering Thermocouples, Atmospheres, and Flow Power.

 

Heat Treat Tip #4

Pack Your Thermocouples

When a thermocouple is used with an open-ended protection tube, pack rope or fiber between the thermocouple and the protection tube to prevent cold air infiltration from influencing the reading.

Heat Treat Tip #7

A Good Fit

If a thermocouple fits loosely in a protection tube, avoid errors by ensuring that the tip maintains good contact with the tube.

Heat Treat Tip #25

Oxygen Analysis as a Cost Saver

Investing in and using an oxygen analyzer on a regular basis can provide significant fuel cost savings and, at the same time, optimize uniformity and maximize capacity.

Heat Treat Tip #26

Flow Power

Pressure varies as the square of the flow. This means that to double the flow, with all else being constant, pressure must increase by a factor of 4. Also, power increases as the cube of the flow. Doubling the flow produced by a fan or blower requires an 8-fold increase in horsepower.

Heat Treat Tip #77

Puzzling Polarity?

If unsure of the polarity of a type K thermocouple, remember that the negative (red) leg is magnetic; the positive (yellow) is not.

Heat Treat Tip #94

Copper as a Leak Check

If maintaining dew point is a problem, and it’s suspected that either an air or water leak is causing the problem, run a piece of copper through the furnace. Air will discolor the copper; water will not.

Heat Treat Tip #97

Optimum Dew Point

It is much easier to produce low dew point gas in a generator (within reason) than it is to lower the dew point after the atmosphere is in the furnace using enriching gas.
