Various precast shapes
Knöllinger produces major-scale refractory parts of up to 8 tonnes, e.g. vacuum seals, electric furnace cores, tundish covers etc.
We also supply customers from the fields of furnace construction (walking-beam furnace, forge etc.), coke production (door stoppers) and the fibre industry. Innovative employment concepts for high-temperature treatment methods are designed specifically to meet customer requirements.
The gas-powered large-scale dryers in our plant feature a capacity of 8,400 x 2,650 x 2,900 mm (L x W x H). This allows almost all common component formats to undergo controlled, fully documented heat treatment at up to 400°C. For special applications, our plant is also equipped with batch furnaces for firing temperatures of up to 1,200°C.
