R&D, design, production and quality control consolidated with many years of outstanding experience. You can find our products everywhere heat treatment takes place.
LHT protective gas furnaces of the models VMK-S/Vac, useful chamber 2,6-15 liter and KS-S/Vac, useful chamber 70-460 liter, are used for bright annealing of steel and other metals. With both models, it can be worked with temperatures above 1150°C with protective gas and, depending on model size, up to 600°C resp. 1000°C under vacuum. Mainly it is worked under forming gas with hydrogen contents < 5 % and in case of oxidation sensitive components with 100 % hydrogen or cracked gas.
For latter use, the furnaces are equipped with the standard options gas-feeding device, burning-off
device and safety package.
Additive Manufacturing (Rapid Prototyping, Rapid Tooling, 3D printing): Especially smaller sized VMK-S are used for bright annealing of 3-D printed parts in additive manufacturing.
The optimization of production lines often requires treatment in continuous furnaces. Therefore, Linn manufactures small and middle-sized continuous belt furnaces up to 1150 °C with protective gas insert muffle and the necessary safety devices for operation with flammable gases.
