The technology relates to a novel industrial gas quick cutting nozzle for cutting metal materials, which consists of a cutting nozzle main body, a spiral mixer, a cutting nozzle jacket, a cutting nozzle inner nozzle and a connecting rod, and is characterized in that one end of the cutting nozzle inner nozzle is connected with the connecting rod through an internal thread, and the other end of the connecting rod is connected with the cutting nozzle main body through an external thread; 10-20 tooth slots are milled on the inner nozzle of the cutting nozzle as fuel gas channels, and the nozzle hole is a streamlined Laval hole, which consists of four parts: a stable section, a contraction section, a throat section and a diffusion section, and surface electroplating treatment is adopted in the streamlined hole; Install a spiral mixer at the thread of the inner nozzle of the cutting nozzle. The novel industrial gas quick cutting nozzle of this technology is applied to a flame cutting machine. When cutting steel, the cutting surface is smooth, the cutting speed is fast, there is no undercut, burning, slag hanging, carburization and hardening, and the service life of the cutting nozzle is long.

Synergistic natural gas

It is a new type of industrial gas, which takes natural gas as the main raw material and is mixed with natural gas gain agent by a gas-liquid mixer. The combustion temperature can be increased by 400-600℃, and it can be used for industrial cutting, welding and baking, and can completely replace acetylene and propane. It can be widely used in steel mills, steel structures and shipbuilding industries, and can be used safely in cabins. The products on the market now include Shenqi I gain agent and Shenqi II gain agent.
