High Purity Self Lubricating Pyrolytic Extruded Graphite Tube
High Purity 1.85 G/Cm3 Pyrolytic Extruded Graphite Tube
Introduction
1,The graphite solid die,flat die,hollow die,productive cover,insulation sleeve,they can be used to product oxygen free copper rod ,oxygen free copper row,oxygen free copper tube with the top leading continuous casting machines. And the flake graphite which can be used in the holding furnace to keep the temperature and insulate the oxygen.
2,The coating solid die,flat die,stopper rod and base and so on,they can be used to product the brass rod, brass bar, brass pipe, copper rod, copper bar, copper pipe and all kinds of special-shape copper products with the horizontal continuous casting machine, and graphite crucibles which are used for smelting metal.
3,The bottom bowl, tube,stopper rod,all of them can be used to make big size copper rod with the semi continuous casting machine.
4,The carboatomic rings, bearing, diamond sintering used for mechanical seal ;the heating machine used for the single furnace; the graphite plate, graphite bar, and graphite grill used for the powder metallurgy industry.
Our products have high technical content, the main technical index has reached the international advanced level, some high-tech products filled the gaps in the domestic. We always put " quality first and customer above all "as our tenet. Warmly welcome to corporate with all friends from all over the world.
