Steel plate cutting parts

     Steel structure cutting is a process that uses a mixture of industrial gas and oxygen to generate high temperatures, melting, slag removal, and splitting steel. It is primarily used in the processing and manufacturing of steel structural components. Key technologies include flame cutting, waterjet cutting, and plasma cutting. Flame cutting has become the mainstream process due to its low cost and ease of operation.

     Early cutting processes primarily used acetylene gas, but this was gradually phased out due to environmental pollution and safety concerns. In recent years, propane, oxyhydrogen, and natural gas have been adopted as alternative fuels. Natural gas, by adding synergists to increase the flame temperature, has developed into a low-carbon, environmentally friendly technology. Waterjet cutting, due to its high precision, is suitable for thin plate processing, while plasma cutting excels in non-ferrous metals such as stainless steel and aluminum. Industry standards have standardized the cutting process, clarifying equipment selection, material testing, and operating procedures to ensure quality.

     Flame cutting refers to the process of melting, slag removal, and splitting the steel structure by burning a mixture of industrial gas and oxygen to the required cutting temperature. Currently used technologies include flame cutting, waterjet cutting, plasma cutting, and CNC cutting. The most commonly used cutting method is flame cutting, which features low cost, ease of operation, mature technology, and widespread adoption. It is currently the most widely used cutting technique in industry. Flame cutting involves using a mixture of industrial gas and oxygen to heat the metal being cut to the melting point of the steel. The flame then releases a high-pressure stream of oxygen, causing further intense oxidation of the metal and blowing away the resulting slag to form the cut. Currently, the main cutting gases in use include acetylene, propane, oxyhydrogen, Kasumigaura gas, and natural gas. Acetylene has drawbacks such as severe pollution, severe injuries to workers, prone to backfire, and high cost, and has now been phased out by government regulations. Propane, oxyhydrogen, and Kasumigaura gas are relatively expensive. Natural gas cutting is a new technology developed in recent years. It has the advantages of low carbon and environmental protection, safety and stability, low cost, and abundant gas sources. It is a technology vigorously promoted by the country and has broad prospects. The flame temperature of ordinary natural gas with oxygen combustion cannot reach the flame temperature of acetylene with oxygen combustion. It is necessary to add temperature-increasing combustion-supporting additives (such as Shenqi natural gas enhancer, etc.) to react with the gas for complexation. After catalysis, activation, and heat accumulation, the cutting temperature required for natural gas cutting can be achieved.
