A manufacturer of heavy duty gas turbines has ordered a vacuum furnace with screen insulation and molybdenum heating elements. Siemens Energy Global will be provided the furnace by a company with U.S. locations and it will be used mainly for brazing gas turbine hot path parts like blades & vanes.

Siemens Energy Global has chosen SECO/WARWICK to provide the vacuum furnace. The device on order includes a mechanical pump, an efficient Roots pump, and a diffusion pump. The molybdenum heating chamber ensures a required temperature distribution and provides process cleanliness.

“The Vector vacuum furnace solves the partner’s problem of heat treating an increased number of large blades & vanes requiring a high degree of cleanliness in both the brazing and annealing processes. The Vector will relieve the production burden on the current equipment in operation in the client’s manufacturing & repair facility in Berlin.” said Maciej Korecki, vice president of the vacuum segment, SECO/WARWICK Group.

“We used a molybdenum heating chamber, partial pressure system, dew point sensors, and a very efficient high vacuum system. An important aspect is also the fact that the furnace will be integrated with the client’s master system using the OPC Unified Architecture communication protocol. Thanks to this, we can connect with a wide range of machines and industrial devices,” commented Grzegorz Głuchowski, sales manager for SECO/WARWICK.

The heat treatment processes associated with this furnace are benefited by the ability to cool at 1.5 bar in argon.

A heat treater with surface hardening capabilities recently expanded its operational line with a vacuum furnace. The new equipment offers a working space of 35.5 x 35.5 x 47 in (900 x 900 x 1200 mm), enabling the processing of larger elements.

This is the 14th vacuum furnace that SECO/WARWICK has provided to Aalberts surface technologies Group, which specializes in vacuum heat treatment, vacuum brazing, hardening of stainless steels, and coating systems for industry. It is the seventh Vector vacuum furnace to be installed at this location in Eindhoven, The Netherlands. It is equipped with high-pressure hardening of 15 bar abs., the option of installing liquid nitrogen, convection heating, directional cooling, and isothermal quenching.

“The solution design is based on the standard VP vacuum furnace Vector type solution. Vector has a round heating chamber and an efficient cooling system,” said Grzegorz Głuchowski, sales manager at SECO/WARWICK. “The additional option of installing liquid nitrogen allows for the load faster cooling after the hardening process. This translates into the furnace’s greater efficiency.”

“This will be the seventh SECO/WARWICK solution operating in Eindhoven. This time, delivery time was key. The solution we ordered is quite specific. We have specific requirements, which are the result of over 80 years of industry experience. The Vector vacuum furnace’s design from the customer’s perspective is very well thought out, as it allows for modifications and additional options. It is one of the most flexible metal heat treatment furnaces on the market,” said Steffen Schneiders, managing director of “The Netherlands & Nordic” from Aalberts surface technologies.
