Unmolted scrap, skulls or heavy residuals may obstruct the tap hole after tapping. Sometimes obstructions are drilled by the operators by oxy-cutting Moreover, lancing is non effective in case of slag skulls, concrete or graphite blocks. These tasks, although not very frequent, normally generate long delays, sometimes hours. Production loss and cost associated, plus hazard injuries risk for the operatorrepresent a very serious issues.
The STROP is a hydraulically actuated equipment that inserts a sturdy rod into the tap hole that is able to lift heavy loads and free the tap hole from any kind of obstruction.
