How to make the graphite mould and how to form the graphite mould?
Graphitized productsSuch products include graphitized electrodes, graphitized anodes, graphitized blocks, high-purity, high-strength, high-density graphite, etc..These products are made of petroleum coke or asphalt coke as the main raw material. At last, they are treated at high temperature over 200 degrees Celsius to convert amorphous carbon into graphite. Its characteristics, C > 99%, gray powder 0.5%, conductive and electrothermal good, good corrosion resistance; production process complex and long cycle, generally 40~60 days.
Commercial pasteIs that the raw material (after crushing anthracite or coke particles and binder) under the condition of heating mixed evenly, without pressure and further heat processing, and as long as the paste material after heating and mixing in normal circumstances, a simple block or a container to use the product. According to the use of two can be divided into one, as a continuous self baking electrode used; the other is the use of carbon block block bonding and caulking material. The manufacturing process of the paste is simple, the production cycle is short, and the cost is low.
Carbon productsThe forming of the blank, the product only 1300 degrees Celsius after calcination can be used, can be divided into low ash carbon products C > 99%; multi ash carbon products C > 90%, the production cycle is generally 30 days.
