Flame cutting is the oldest thermal cutting method, and its cutting metal thickness ranges from 1mm to 1mm, but when the thickness of most low-carbon steel plates you need to cut is less than 20mm, other cutting methods will be adopted. Flame cutting is to cut carbon steel by using the high temperature generated during the combustion of iron oxide. The design of flame cutting torch provides sufficient oxygen for burning iron oxide and ensures good cutting effect.

Numerical control flame cutting machine is mainly suitable for cutting medium and heavy plates. Compared with other similar thermal cutting methods, CNC flame cutting machine has the characteristics of high cutting quality, good verticality of cutting surface and large cutting thickness, and is the most widely used cutting method in the domestic market at present. Its main advantages are as follows:

1, and the cutting surface is highly vertical.

Different from the V-shaped cutting surface produced by the plasma arc of the NC plasma cutting machine, the verticality of the cutting surface processed by the NC flame cutting machine is generally higher, and the inclination can be controlled below 2-3, which is characterized by better cutting performance for the surface with a certain thickness above10 mm. ..

2, the cutting thickness is large

In practical processing applications, the processing thickness of flame cutting varies from 6 to 6-200MM, and the cutting thickness can even reach 350MM by changing the gas path of the trachea and the cutting nozzle of the cutting torch. In order to better improve the cutting quality, the related process parameters will be slightly different when flame cutting materials with different thicknesses.

3, the cutting quality is high

Generally speaking, flame cutting is mostly used for medium and heavy plate cutting. When cutting materials with the thickness of similar materials above 20MM and basically within 100MM, the cutting nozzle is easily blocked due to the serious slag turning during piercing operation, so it can be cut from the edge of the steel plate, the cutting width can be kept within 20 mm, and the cutting speed can be kept within 0-700mm/min. At the same time, it is equipped with an automatic height adjustment control system to make cutting.
