Qingdao Haixi anti-corrosion insulation equipment tells you: can the metal surface be cleaned with a shot blasting deruster?

In the foundry industry, derusting equipment is first used to cast steel and cast iron surface sand and oxide layer. Most steel castings, gray castings, malleable iron castings, ductile iron castings and so on need shot blasting. This can not only remove the oxide skin and sand on the casting surface, but also make necessary preparation before casting quality inspection. For example, the shells of large gas turbines are subjected to strict shot blasting before non-destructive inspections are carried out to ensure inspection results. High reliability. In general casting production, sandblasting is the key process to find defects on casting surface (such as subcutaneous pores, slag holes, grinding, cold insulation and spalling, etc.). The main purpose of surface cleaning of nonferrous castings (such as aluminum alloy, copper alloy, etc.) is to remove burrs in die castings, so as to achieve overall cleaning effect, in addition to removing oxide skin and discovering surface defects of castings.

Rust prevention is an important link in steel structure production. If not properly handled, it will directly affect the quality and service life of the steel structure, shorten the maintenance cycle of the steel structure or affect its service life, and sometimes cause structural defects.
