Ladle Unshaped Refractory Material
Ladle unshaped material uses high quality calcined magnesia and magnesite calcium materials as raw material. Raw materials of certain proportion particle sizes mixes with different kinds additives and organic-inorganic composite binding agent, we can get this high quality product. This product is characterized by good transportaion, wettability, high adhesion rate, small resilience, strong spalling and erosion resistance, it can get hard in a very short time.
