Our advantages:
1. High purity
- Control the consistency of raw material from the mine resource.
- Introduce automatic whole-process equipment to ensure product consistency.
- Not allowed any harmful impurities during raw material & production process.

2.Fine classification
- Choose different raw materials according to their characteristics.
- Various product category, to provide customized slag treatment scheme

3. Environment friendly & health
- The reaction process is only a change of physical state, not chemical reaction, so no solution to the molten metal.
- The physical reaction is stable and non-toxic and tasteless. It does not produce soot & not affect human health.

4).Mechanism of slag removing
- Low softening point, high viscosity. After being scattered into the metal surface, the product will expand and
- Spread out to cover the entire surface, melt rapidly, form a high-viscosity "film" finally, which
sticks to the scum in the metal, to make slag collected and removed.
