Graphite Block
Raphite block/square (Extrusion ,Molding ,Isostatic pressing) is a main graphite products. The production process is similar with graphite electrode, but not a by-product of graphite electrode. There are a lots of classification, the production process is complex, and general production cycle is higher than two months. Also, there are variety types of graphite block/square. According to the different processing technology it can be divided into extruding graphite block/square, molding graphite block/square, isostatic pressing graphite block/square.
Generally, it can be divided into extrusion graphite block/square, molding graphite block/square and isostatic pressing graphite block/square in accordance with different processing technologies.
