Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel 15CrMoR storage tank steel plate. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.

Phosphorus is a very harmful element in 15CrMoR storage tank steel plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of 15CrMoR storage tank steel plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
