How to reduce iron levels in silica sand
Removing iron from silica in sand washing processing LZZG. The purity requirement of quartz sand in high-tech field is harsh: generally requires SIO2 content greater than 99.99%, impurity content, especially The content of iron impurities is limited to a very low range, so it is very important to increase the taste of quartz sand in the production process to reduce the content of iron.

Types of Casting Defects in Sand Casting African
2021-5-10 When large sand grains are used, the molten iron fuses into the sand and solidifies, producing what is known as metal penetration defect. Metal penetration is caused by the use of low strength, large grain size, and highly permeable sand. Consequently, molten metal penetrates the molding sand, producing a rough and uneven cast surface.
