Clay-Based And High-Alumina Based Plastics


The plastics are mud like materials made of refractory aggregate and powder at certainparticle size distribution with binder and additives.After packing and storage for a period oftime,they still have good plasticity,are available for ramming.Featuring high strength,good resistance to thermal shock,spalling and slag,small thermal conductivity and longs ervice life,they are suitable for easy damaged areas such as roofs and burners in various reheating furnace,soaking furnace,annealing furnace and EAF in the iron and steel industry.
