Advantages and disadvantages of oxygen-natural gas flame

Advantages and disadvantages of oxygen-natural gas flame

For a long time, metal flame cutting has been using acetylene + oxygen process mode or propane industrial gas + oxygen process mode. In the field of industrial cutting, acetylene has been used for a hundred years, but acetylene gas is flammable and explosive and has a low safety factor. The production process consumes energy […]

What are the differences between the three types of preheating flame for oxygen-acetylene flame cutting?

What are the differences between the three types of preheating flame for oxygen-acetylene flame cutting

Because of the different types of fuel gas, the cutting flame can be divided into oxygen-acetylene flame, oxygen-propane flame, and oxygen-natural gas flame. Among them, the oxygen-acetylene flame burns to produce a very high temperature (about 3200°C), and the heat is concentrated, which is the flame often used in cutting. By adjusting the mixing ratio […]

What are the defects of the CNC flame cutting machine cutting workpiece?

What are the defects of the CNC flame cutting machine cutting workpiece

Flame cutting is a common method for rough processing of steel plates. It is a relatively mature thermal cutting method. The cutting metal thickness ranges from 1 mm to 1 meter and is suitable for cutting steel plates above 20 mm. Flame cutting uses the high temperature generated during the combustion of iron oxide to […]

Advantages and disadvantages of flame cutting

Advantages and disadvantages of flame cutting

Metal cutting is a necessary process for most metal processing. For example, in sheet metal processing, we need to cut the steel plate into the rough shape we need and then finish it into the required parts. Numerical control flame cutting uses a digital motion control system, through the system to write processing programs or […]

What is a CNC flame cutting?

what is flame cutting

Flame cutting is a common method for rough machining of steel plates. Flame cutting is gas cutting. Traditionally, acetylene gas is used for cutting. Later, propane is used for cutting. Now natural gas cutting appears. Because of its abundant natural gas reserves, low price, and pollution-free characteristics, it has become the first choice for flame […]
