How can we reduce the cost of steel plate flame cutting

When do steel plate flame cutting, we need to consider the cost. How to reduce cost of steel plate flame cutting?

In terms of gases, there is one kind of gas that is essential, and that is oxygen. It is not only necessary for combustible gas combustion, but also for steel burning after reaching the ignition point. Therefore, it is required that the oxygen used for steel plate flame cutting should have a higher purity, generally more than 99.5%. And we should pay attention to that if the purity is reduced, then the cutting speed of steel plate will also be affected, and it will decrease accordingly. If the reduction range is 15% - 20%, it will cause very bad consequences, which will affect the production efficiency and steel plate flame cutting quality, but will increase the production cost.

In fact, in addition to oxygen, we can also use liquid oxygen. Although its one-time investment is relatively large, it is much better from an economic point of view.

The stability of the gas pressure is also very important because it will affect the cutting quality of the workpiece. If the oxygen pressure fluctuates, it will seriously affect the cutting section. The pressure is related to the type of cutting nozzle and the thickness of steel plate.

In steel plate flame cutting, the commonly used combustible gases are acetylene, gas, natural gas and propane. The gas with fast burning speed and high combustion value is more suitable for thin plate cutting, otherwise it is suitable for thick plate cutting, especially for steel plate with thickness more than 200 mm.
