Pre-melted refining slag is a new-generation auxiliary material for the steel industry, mainly used in LF furnaces, open-hearth furnaces, and converter ladle refining to remove impurities such as sulfur and oxygen from molten steel, reduce harmful elements and impurities in steel, and improve steel quality. The product has the following characteristics:

(1) Uniform composition, low melting point, fast melting speed, which can shorten refining time;

(2) Fluorine-free, protecting the ecological environment and not eroding furnace linings;

(3) Non-hygroscopic, facilitating storage and transportation;

(4) Due to uniform composition and rapid slag formation, it can reduce dust pollution in steel plants;

(5) Free of hydrogen, nitrogen, and other impurities, with excellent metallurgical effects, helping to improve steel quality.

Mainly used in LF furnaces, open-hearth furnaces, and converter ladle refining to remove sulfur and oxygen impurities from molten steel and reduce harmful elements and impurities in steel.

Product specifications:
Particle size: 0-3mm, 3-50mm.
Main production types: high-aluminum, high-calcium, and high-magnesium models. Custom orders are accepted.

Electrically Fused Pre-melted Multifunctional Refining Slag‌

Currently, most steel plants in China widely adopt ladle refining technology to reduce gas inclusions, homogenize molten steel, and achieve high-yield, high-quality, and low-cost steelmaking. Consequently, the requirements for ladle refining slag are becoming increasingly stringent.

To meet these demands, our company has organized technical personnel to conduct extensive and meticulous research on production processes, collected comprehensive data, and actively collaborated with overseas academic institutions such as the German Metallurgical Association and the American Society of Mining, Metallurgical, and Exploration Engineers (SME), as well as domestic universities and research institutes. These efforts have steadily improved product quality.

Based on user feedback, the performance of our refining agents has reached or even surpassed that of imported products.
