Round Molded Graphite

As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.

The high-purity graphite, graphite block and Molded Graphite produced by Pingdingshan Carbon Graphite Factory for many years are excellent, and the specifications of Round Molded Graphite are as follows: φ 450*800, φ 520*400 φ 630*420, φ 660*620 φ 780*600, φ 820*350~500 φ 900*350~400, φ 1050*350~400 φ 980~350*400, φ 1160*350~680 φ 1260*350~680, φ 1330*400 φ 1420*400, φ 1520*400 φ 1630*350, φ 1800*350 φ 2000*350, φ 520~2000*680
