Does water vapor affect the quality of steel shot casting?

　　In the casting process of steel shot, some factors will seriously affect the production quality and effect of the equipment, which need to be avoided in time, and water vapor is one of the serious influencing factors. Water vapor exists in a gas-liquid state. When the product is produced, some applications are exposed to high ambient temperatures, resulting in the presence of water vapor. Over time, all products will oxidize, which will affect the use of equipment. So, let us briefly understand the influence of water vapor on the casting quality of steel shot.

　　1. Because water vapor-rich substances can dissolve in oxide crystals, oxidation kinetics are affected when water vapor is present.

　　2. When the steel shot is rich in water vapor, the water vapor will accelerate the high temperature oxidation.

　　3. Water vapor is still one of the main reasons affecting the growth of high-temperature oxide scale on steel shot, because the differentiation effect between the oxide film and the water vapor interface accelerates the growth of oxide scale.                                                                                           4. Water vapor can migrate from the oxide film to the oxide layer by using some small pores.

　　Water vapor is unavoidable in a high-temperature environment, and its long-term corrosion by water vapor will affect its service life. To avoid this scenario, it is necessary to improve technology and ensure application quality. Steel shot is an ideal abrasive for finishing finishes because of its durability when used with the right equipment. It has the advantages of moderate hardness, strong durability, impact resistance, reusable use, long service life, good rebound, strong adhesion, fast finishing speed, low sand consumption, no breakage, high brightness of finished workpieces, and good technical effects. The metal appearance cleanliness of the product after treatment has reached international standards. The surface roughness is between 25~150m, which increases the contact surface of the metal surface and improves the adhesion of the altered surface. Steel shot has obvious economic benefits for refining metal surface and strengthening metal structure, and is an ideal finishing, spraying, derusting and strengthening material.
