Unshaped refractory material series

the super-low cement and non-cement refractory castables and relevant products the super-low cement and non-cement refractory castables are featured with the advantages of most refractory castables. They have high density, low porosity, high strength, resistance to heat shocks, anti-erosion, etc. They have various applications. All technical parameters of the high-aluminum-super-low-cement slug shield and magnesite-non-cement slug shield made in this company are superior to those competitive products.
Refractory ramming material series		Refractory dressings
including magnesia-alumina spinal and magnesite, etc.		mainly including magnesite pouring basket coating which is characterized with good thermal insulation, pure liquid steel, long life and stable quality, etc.
