By the flame cutting, unalloyed and low-alloyed steels of particularly great thickness can be separated.
For the cutting of non- and low-alloyed steels, the autogenous flame cutting is frequently employed. That means the cooperation of an oxy-fuel flame with a high-velocity oxygen jet.
Despite the more and more strong competition of the plasma and laser cutting, this economical and versatile process still has a great significance for the manual and mechanical applications in industry and handicraft.
Flame cutting of steel sheets with oxygen
For the starting and the maintenance of the flame cutting process, a powerful heating flame is required. The employed fuel gases vary in the flame temperature, the ignition speed and the primary flame power. The largest part of the needed energy for the process is provided by the burning of the processed materials.
Flame cutting in the metal processing industry
In the process, the material to be cut is locally preheated to an ignition temperature and is separated by burning the material with a fast flowing oxygen jet.
The cutting with acetylene can there – because of its high flame temperature and ignition speed – contribute decisively to the economy of the process.
In order to utilize the physical and chemical properties of our gases developed for the flame cutting, all parameters must also be optimally adjusted to each other. We...
