Stainless steel rod breaking and cutting processing method-Spray powder cutting

When oxygen-acetylene gas is used to cut 304 stainless steel rods, the main difficulty is that the surface of the slit forms a high melting point of chromium oxide, which prevents the burning of the metal and causes difficulty in continuous cutting.

In order to smoothly cut the 303 stainless steel rod, in addition to having a sufficiently pure, pressure-bearing oxygen and a good cutting wind (that is, having a long and powerful cylindrical cutting oxygen flow), some special processes are also required. Measures.

Usually, iron powder is directly ejected by cutting oxygen, and heat generated by burning iron powder in a common oxygen-acetylene flame. The molten iron oxide and chromium oxide are mixed and diluted, and in the case of a significant increase in heat, a mixed liquid slag is formed, which is blown off the slit by the cut oxygen. It can cut thicker 304 stainless steel sheets or casting risers.

For welded containers and pipes made of acid-resistant stainless steel, the 304 stainless steel rod should be unloaded and the groove should be opened. The hole should be opened during the manufacturing process. The back of the weld is often removed. The weld has a flaw. I have to go back to my illness.

These processing steps are indispensable in the production and manufacturing process. These processes are mainly carried out by mechanical methods such as shearing, planing, milling, turning… and require many types of mechanical equipment.

In some cases, the air shovel is used, which is labor intensive and has a lot of noise. The use of gas flame and gas-electric methods to complete these processes has many advantages for improving working conditions and improving efficiency. The disadvantage is that the processing accuracy is worse than mechanical processing.
