Vágógázzal

Vágógázzal is a term used in Hungarian to describe a specific type of gas mixture employed in oxy-fuel cutting processes. This term translates directly to "cutting gas" and refers to the fuel gas used in conjunction with oxygen to produce a high-temperature flame capable of melting and severing metal. The most common vágógázzal is acetylene, due to its very high flame temperature, which makes it highly efficient for cutting steel.

Other fuel gases can also be used as vágógázzal, including propane, propylene, and natural gas. While these may produce slightly lower flame temperatures than acetylene, they are often more economical and safer to handle and store. The choice of vágógázzal depends on factors such as the type and thickness of the metal being cut, cost considerations, and safety protocols.

The process of oxy-fuel cutting involves preheating the metal to its ignition temperature using the vágógázzal and oxygen flame. Once the metal is hot enough, a jet of pure oxygen is directed at the heated area. This oxygen reacts with the metal, rapidly oxidizing it and blowing away the molten metal and slag, thus creating the cut. The effectiveness of the vágógázzal is crucial for achieving clean and efficient cuts.
