A manufacturer of machining tools, industrial knives, mulching knives, and chippers has placed an order for a vacuum furnace with 10 bar high-pressure gas quenching. It will be used for tool steel hardening and tempering processes.
The furnace on order, the Vector® -- a furnace from North American SECO/VACUUM and the international SECO/WARWICK -- has been adapted to match the Czech manufacturer's needs: SECO/WARWICK engineers have designed a 600 x 600 x 1800mm work space. The device modification was implemented to fit the long and straight characteristic shape of the workpieces. The unit was also equipped with a directional cooling option to effectively cool down long and thin knives that, a shape that's prone to distortion during the hardening process.
The application for the device required an inverter that enables complete control over temperature at every stage of the hardening process to reduce distortion. Together with the additional option of directional cooling and the convection system, the system design helps to reduce the undesirable distortion significantly.
