For the ductile iron covers we certainly will not be unfamiliar, we will go
out every time you expect to see a lot of it! This thing is inconspicuous, may
also be often stepped on the foot, but very important. Though you are stepping
on the floor every day, but do you know that the ductile iron covers are needed
to be cleaned! So where do you need to clean and how to clean it?
1, ductile metal surface dust
Casting is often carried out in dusty venues where the air often carries a lot of dust, which constantly falls on the surface of the equipment, which can be removed with water or alkaline solution, but the adhesion of dust requires high pressure water or steam Clean up.
2, ductile iron pieces surface float iron powder or embedded iron
On any surface, free iron will rust and produce corrosion of stainless steel. Therefore, it must be removed. Float powder can be removed with the dust together. Some adhesion is very strong, must be embedded iron processing.
3, ductile castings scratches
In order to prevent the process lubricant or product and / or dirt from accumulating, scratches and other rough surfaces must be mechanically cleaned.
4, ductile cast rust
Before or during the production process, it is sometimes seen that the stainless steel product or equipment is rusted, indicating that the surface is heavily polluted. The equipment must be removed before use and the thoroughly cleaned surface should be carried out by iron test and / or water test test.
The above is about the ductile iron cover clean, not only need to clean the dust, and the covers on the rust, scratches and so need to be processed.
