It's important to inhibit steel splashing inside the vacuum vessel to avoid skull buildup. RH-SC® does this during rapid decarburization treatment using advanced vacuum pressure and lift gas flow control.
Fewer splashes reduce skull formation inside the vacuum vessel. As a result, less effort is necessary for skull cutting with hydrocarbon fuels and/or oxygen applied through burner lances. This not only directly saves resources but also reduces skull handling, recycling, and disposal.
Skull cutting tends to damage the vessel lining, so reducing it increases the refractory lifetime. It also decreases the volume of worn-out refractories that have to be dumped and/or recycled. Another advantage of less splashing is that not as much dust is generated to contaminate the condenser cooling water. That eases the load on the water treatment plant.
