Refractory gunning
With our gunite machines, you get the equipment you need to repair the refractory linings of your units. Our gunite machines have already proven themselves in foundries, steel, metallurgical and cement works around the world. We can process a wide variety of gunning compounds based on silica, magnesite or alumina. For “dense gunning” of LC, ULC or NC concretes with high compaction and low porosity, we recommend using our patented GUNMIX moistening system

Rotor gunite machines
Our rotor gunite machines have proven themselves in the refractory industry and work continuously in a large output range.
Pressure vessel gunning machines
Our pressure vessel gunite machines are recommended for larger output capacities and bigger quantities to be processed. They are usually filled with big bags.
Machines for Hearth Materials
Our hearth mass machines help you repair the transitions from the side walls to the floor in the electric arc furnace.
Centrifugal Machines
The slag zone and the side walls of the electric furnace can be quickly repaired with a centrifugal machine. There are models for dry and wet slinging.
Tundish Ladle
Machines for pumping refractory concrete and processing slurry gunning mixes for spraying distributors (tundish)
Advantages of dry gunning technology
Die Trockenspritztechnik zählt als die wirtschaftlichste Methode. Die Spritzmasse wird erst an der Düse mit Wasser befeuchtet und mithilfe eines hohen Druck auf die Wand gespritzt. Damit verbessern Sie die Haltbarkeit der Reparaturstelle. Die Maschine ist schnell und einfach zu reinigen.
