Product Description

Product Description

Low-silicon refining slag (with low SiO2 content) is primarily used in secondary steel refining processes (e.g., LF furnace) to optimize molten steel quality through:

Application of low-silicon refining slag

1.Efficient Deoxidation & Desulfurization

Dominant CaO-Al2O3 components reduce slag oxidizability,

2.Non-Metallic Inclusion Absorption

Low-viscosity slag effectively captures inclusions (e.g., Al2O3, SiO2), enhancing steel purity.

3.Lining Protection & Corrosion Reduction

Low SiO2 minimizes reactions with alkaline linings (e.g., MgO-C bricks), extending equipment lifespan.

4.Composition Stability Control

Item	Al2o3	CaO	SiO2	Fe2O3	N	Ti	Grit Size	Moisture	Melting Point
Low Silicon Refining Slag	≥63	≥15	≤0.9	≤1.2	≤0.08	≤0.8	3-40	≤0.5	1300ºC

Features of low silicon refining slag:

1. Low melting point and fast melting speed, shorten refining time and reduce refining power consumption;

2. Good fluidity, good desulfurization and removal of inclusions;

3. There is no flame, little dust, and good safety;

4. No water absorption, no dust, no deterioration during storage and transportation;

5. The submerged arc has a good effect, which reduces the erosion of the lining caused by the arc and improves the life span.
