PE Oxygen probes

Nordic Metallurgy has a cooperation with United Process Controls GmbH and can now offer a variety of products for analysis and control and of various heat treatment atmospheres and processes. For example a  variety of oxygen probe types are available for different types of atmospheres and operating conditions. United Process Controls  provide a broad range of solutions and equipment for the control and management of carburizing, nitriding-  and nitrocarburizing processes as well as vacuum processes.

Delivery of new furnace in cooperation with CH Evensen Industriovner AS

21 November, 2012

CH Evensen Industriovner AS in cooperation with Nordic Metallurgy recently delivered a new annealing and tempering furnace to Fimek AB in Filipstad, Sweden. The furnace is designed and adapted to FIMEKs special production requirements. The furnace is equipped with a unique air-flow concept to obtain maximal temperature uniformity. The furnace type is also designed to substantially reduce maintenance and to facilitate for example change or inspection of heating elements, or fan replacement without removing heat insulation, lining and guide plates, etc.

High activity when Jame Shaft presented their new heat treatment line

16 December, 2010

On a cold morning in November Mika Tuunainen, CEO of Jame Shaft, greeted a group of Finnish heat treatment professionals to review their heat treatment line that has been in use for a good year now.

Following a dramatic fire in 2009 Jame Shaft ordered a complete new heat treatment line to carburize the axes and pins they machine for heavy duty applications.Specifics of the whole project received a lot of attention and Mika was faced with many tricky questions. When let into the heat treatment area the group scattered all over the equipment and critically inspected components and systems in the control and operation of the line. The vast experience of the visitors was well reflected in all detailed questions and profound comments

To conclude the day, partners of Nordic Metallurgy presented aspects of the heat treatment industry followed by time for more relaxed exchange if ideas and experiences. We thank all participants for their active and inspired approach.

Nordic Metallurgy supplies ”turn-key” hardening line to major Swedish engineering company

21 April, 2009

Nordic Metallurgy recently delivered a complete “turn-key” hardening line to a major Swedish engineering company.
The furnace equipment consists of one hardening furnace together with a tempering furnace. The parts to be hardened are heated to temperature in the hardening furnace and then by the operator controlled handling device directly quenched in the water quench tank. The water tank is equipped with special water agitators guaranteeing a perfectly uniform hardening result. The parts are then directly transferred to the second furnace for tempering.

Low Pressure Nitriding Furnace for Gästrike Härdverkstad AB

11 February, 2009

Gästrike Härdverkstad is the first hardening shop in the Nordic countries choosing  Low Pressure Nitriding. The furnace was delivered by Nordic Metallurgy late 2008 and is now in full production. The furnace is a B54BN model and designed for the Low Pressure Nitriding process (nitriding/nitrocarburising). The furnace is also designed for tempering under vacuum. The B54RN has an effective max load weight of 600kg and max dimension 600 x 600 x 900 mm. Standard Low Pressure Nitriding furnaces are available up to 2000kg load weight.

One reason to why Gästrike Härdverkstad choose this process was that the nitriding takes place under low pressure/vacuum, which means superior reproduceability and a gas consumption just a fraction compared to ordinary conventional nitriding furnaces.
The design also enables much faster heating-up and cooling sequences connected to a substantially lower energy cost compared to conventional furnaces.
