Applications
As a flux in primary aluminium smelting.
Thick size(0-10mm)and good fluidity, Convenient for mechanization and feeding automatically.
Low melting point and fast melting, which can reduce the period of turning into normal working condition
1. Mainly used as flux for aluminum electrolysis;
2. It is also used as wear-resistant additive for grinding products, which can effectively improve the abrasion resistance, cutting and cutting force of grinding wheel, and extend the service life and storage time of grinding wheel.
3. Ferroalloy and fluidized steel flux, nonferrous metal flux, casting deoxidizer, olefin polymerization catalyst, as well as glass anti-reflection coating, enamel emulsifier, glass emulsifier, welding flux, ceramic filler, pesticide insecticide and other industries.
