Feature:
ZC-ZM is melted and casted in high temperature electric furnace by high quality mullite grops,it is mainly used in areas that require good wear-resistance and high temperature resistance,such as gliding rail bricks in steel pusher metallurgical furnaces,the tapping platform(tapping spout)for tapping platform (tapping spout)style walking beam metallurgical furnaces,and also as the interior lining for destructors.
PRE-ASSEMBLY
After finishing process,the produces will be assemble and checked in partial individual and overall dimensions.Pre-assembly marks,joint marks and other signs(as per customer’s requirements)will be painted on each individual block according to customer requirements
Packing and delivery
Consider various and complex transportation conditions,all fused cast products are packing following the highest standards with foam boards between every two blocks,corners protected with triangular hard cardboards,multi-strengthened by steel bands,wrapping in plastic film on the outside
For easy location of different materials,packing lists are places both inside and outside packages,and shipping marks are clearly painted on all cases.
