Core Performance Advantages

• Excellent alkali corrosion resistance: Its primary advantage. The main MgO and CaO components effectively resist chemical erosion from alkaline slags, high-calcium cement clinker and steelmaking slags, extending furnace service life.
• Superior refractory performance: After high-temperature "dead burning", it has a refractoriness of over 2300°C and stable volume, meeting the operating temperature requirements of most high-temperature industrial furnaces.
• Molten steel purification: In steelmaking, CaO dissolved from dolomite refractory enters the slag, helping remove harmful impurities like sulfur (S) and phosphorus (P) from molten steel to improve purity.
• Environmental friendliness and chromium-free: It can fully replace traditional magnesia-chrome bricks, avoiding toxic hexavalent chromium (Cr⁶⁺) compounds, making it a key choice for "green refractories" and eco-friendly production.
• Resource and economic benefits: For regions lacking magnesium resources but abundant in dolomite, it is a cost-effective alternative to magnesia refractories.

Main Product Forms

• Dead-burned dolomite sand (raw material)
• Dolomite bricks
• Dolomite unshaped refractories (castables, ramming mixes and furnace repair materials)

Main Application Fields

• Cement industry: Burning zone and transition zone of cement rotary kilns.
• Steel industry: Working linings of converters and electric furnaces, and ladle slag lines.
• Glass furnace regenerators: As checker bricks, they outperform some magnesia bricks in resisting alkali vapor erosion.
• Non-ferrous metallurgical furnaces: Used in smelting environments handling alkaline slags.
