Refractory gunning machines,-robots and pneumatic injection
For more than 50 years VELCO is known as reliable partner for the steel and refractory industry.
Velco supplies refractory gunning and slinger machines, as well as tailor made manipulators for the hot gunning repair of EAF, ladle and RH snorkels.
Newest models of gunning robots include camera's and auto- gunning options.
With VELCO’s patented moistening system GUNMIX (R) the mixture of material and water is improved.
This reduces dust and rebound in the dry gunning process.
VELCO also produces pneumatic transport equipment for the injection of e.g. carbon or lime at the EAF, for slag foaming process or for analysis correction and desulfurization at the LF. Machine type EKS-K has a rotor feed dosing included which gives a constant material flow with accuracy of 0,5%.
For the repair of local hot spots at the BF VELCO offers equipment by which Rutilit (a synthetic titanium dioxide of Venator Corp.) is injected into the blast furnace tuyere.
