Global Magnesium Oxide (MgO) Solutions

1. Grain-Oriented Electrical Steel Coating Solutions

Strategic Focus: Domestic Import Substitution & Precision High-Temperature Insulation

Industry & Technical Pain Points

• High-grade MgO used as an insulating coating precursor in grain-oriented silicon steel has historically been monopolized by overseas suppliers, creating supply chain vulnerabilities for critical power grid and electronic infrastructure.
• Strict manufacturing tolerances require ultra-high chemical purity, controlled particle size distribution, and superior high-temperature activity to prevent coating defects during high-temperature annealing.

Our Customized Solution

• Specialty Steel-Grade Coating Supply: Developed in collaboration with leading steel research institutes, our proprietary calcination and refining process optimizes particle morphology and purity, matching or exceeding legacy imported products.
• Large-Scale Continuous Manufacturing: Supported by 13 automated rotary furnace production lines ($15,000\text{ metric tons/year}$ capacity), guaranteeing exceptional batch-to-batch consistency and long-term stability.
• Proven Supply Security: Capturing over 70% of China’s electrical steel market, replacing high-cost imports for major domestic steel manufacturers.

2. Battery-Grade High-Purity MgO & Intelligent Dosing Systems

Strategic Focus: Ultra-Low Impurity Material & High-Precision Automated Powder Feeding

Industry & Technical Pain Points

• Lithium battery electrolyte additives and EV materials demand extreme purity ($\ge 99.99\%$) with iron impurities controlled strictly below $5\text{ ppm}$.
• Traditional manual or mechanical powder feeding creates severe dust pollution, high material residue, and batch weighing errors ($\pm 2\%$), degrading battery cycle life.

Our Customized Solution

• Ultra-Pure Light MgO Material: Produced via green leaching and closed-loop liquid recovery, delivering battery-grade purity with minimal trace metals.
• Enclosed Vacuum Transport & Smart Dosing System: An integrated powder handling system featuring adaptive airflow control, full-path static dissipation, ultrasonic anti-bridging, and PID/neural network dynamic compensation.
• Performance Impact: Dosing precision improves from $\pm 2\%$ to $\pm 0.1\%$, material residue drops to 0.08%, workshop dust falls below $0.5\text{ mg/m}^3, and battery cycle life increases by 15%.

3. Circular Economy & Waste-to-Value Green MgO Solutions

Strategic Focus: Resource Recovery from Salt Lake Brine & Low-Grade Tailings

Industry & Technical Pain Points

• Processing salt lake potassium fertilizer generates massive volumes of magnesium chloride ($10\text{ tons}$ of $\text{MgCl}_2\cdot 6\text{H}_2\text{O}$ per ton of potassium), creating severe environmental storage risks.
• Low-grade magnesite tailings accumulate rapidly, leading to land occupation and raw material waste.

Our Customized Solution

• Salt Lake Thermal Decomposition & Electro-Fusing: Patented clean technology converts waste magnesium chloride into 99.85%+ high-purity MgO and electro-fused magnesia while recycling chlorine gas into industrial hydrochloric acid.
• Closed-Loop Magnesite Tailings Extraction: Fully enclosed, zero-discharge liquid leaching technology transforms low-grade tailings into high-value, light high-purity MgO.
• Commercial Value: Eliminates environmental liabilities while supplying premium green carbon materials into artificial crystals, 5G communications, semiconductor packaging, and Fortune 500 supply chains.

4. Refractory Material Continuous Dosing & Anti-Corrosion Systems

Strategic Focus: Heavy-Duty Electro-Fused Magnesia Handling & Yield Optimization

Industry & Technical Pain Points

• Production of high-end refractories (such as magnesia-carbon bricks for steelmaking) requires continuous, heavy-duty dosing of coarse fused magnesia.
• Conventional screw conveyors clog frequently due to moisture absorption and material hardness, dropping system uptime to $65\%$ and product qualification rates below 92\%.

Our Customized Solution

• Heavy-Capacity Vacuum Conveying Systems: Purpose-built PFS-MgO-1200 pneumatic systems delivering up to $12\text{ tons/hour}$ conveying capacity.
• Climate-Controlled, Anti-Clogging Piping: Equipped with constant-temperature insulation to prevent moisture absorption, alongside complete electrostatic grounding.
• Operational Impact: Conveyor blockages drop from 15 times/month to zero, equipment availability reaches 98%+, refractory thermal strength improves by 10%, and product qualification rates surge to 99%.
