Description features:Our company is a professional company in anode steel claw for electrolytic aluminum production by using the advanced professional production line(EPC line) and physics and chemistry measurement and Analyzes laboratory. we have used Electrode Arc Furnace (Intermediate frequency electric furnace) and rare earth fining, had guaranteed the lowest aerometry and impurity in the melted steel, thus obtains the better electric conductivity and lower electronic resistivity. High quality and efficient productions can be directly used economically and practicably without cleaning up by the users thanks to the advanced Lost Foam Production(EPC) line , post treatment by automatic reverberatory furnace processing and surface treatment by shot blasting machine. High qualities productions produced by specialized milling machine, make it very popular among our customers so that it has a wide international market.
