Contiblu®¨ is our oxidation belt kiln for the continuous steam curing of PM shaped parts.
The background: under oxidizing water vapor atmosphere iron oxidizes to Fe3O4 and forms a firm, wear and rust-protecting magnetite layer on the parts. The effect of the steam curing is therefore not only the corrosion and catch ice protection, but also the hardness increase of PM parts. This hardness increase adjusts itself, if first empty pores zuoxidieren by magnetite formation ""and the total stand of the PM of part thereby larger firmness attained. |

FineCarb vacuum carburizing technology has been intensively developed for a number of years by SECO/WARWICK in collaboration with the Materials Engineering Institute of Lodz Polytechnic in Poland. Recently the company has initiated or is in the process of supplying a dozen or so installations, among which are:
- Several single-chamber NVPT vacuum furnaces for, among others, two hardening plants in Italy, as well as companies in Turkey, the USA, Slovenia and Poland. In addition, further single-chamber NVPT vacuum furnaces have been or will be supplied to a Wallwork Heat Treatment hardening plant in the UK and the Bauman Institute in Moscow, Russia;
- A dual-chamber furnace with a ColdKam chamber for a USA-based customer. The furnace was fitted with a 20-bar gas cooling system, which together with the processing chamber is adapted for the construction of SECO/WARWICK ‘multi-chamber’ type systems;
- For a well-known company in the USA, a dual-chamber furnace with oil bath for the vacuum carburizing and hardening in quenching oil of gear wheels with a mass of 5000 kg. The furnace has a processing chamber of f 1800 x 2500 mm.
