Yellow phosphorus is smelted in a submerged arc electric furnace, and the main raw materials are phosphate rock, coke, and silica. During production, these raw materials are pre-dried and crushed to a certain size. Next, the raw materials after drying and crushing enter the closed furnace from several discharge ports evenly distributed on the furnace … Read more
The salt-bath furnace is important heating equipment in the metal heat treatment process with simple structure, convenient use and maintenance, and low investment and maintenance costs. Sometimes, it can also be used in welding processes. The graphite electrode is the core component of the salt-bath furnace. In order to overcome the shortcomings of short electrode … Read more
In the production of carbon products in a certain period of time, Shengli coke with high sulfur content is used as raw material in a considerable proportion. These cokes have the characteristics of high volatile content, high sulfur content, and difficult graphitization. It is difficult to control the production process, so the product is prone … Read more
The reliability of graphitized electrodes in electric arc steelmaking furnaces, in many cases, depends on their ability to resist thermal stress. The final effect of thermal stress depends on the size and nature of graphite deformation. Regarding the deformation properties of graphite electrodes, the research is insufficient. Because people have focused their attention on the … Read more
Several major physical and chemical indicators are controlled within a certain range. It is not that the higher a certain indicator is, the better. In a certain sense, stability is more important than improvement. China’s rp graphite electrode industry-standard stipulates that the resistivity standard of 400~500mm in diameter is no more than 9 Ω·m for … Read more
The graphite electrode blank after graphitization is machined according to the shape and size specified by the quality standard. The graphite electrode body and nipples that meet the requirements of use are made. Processing Equipment for Graphite Products Graphite electrode processing is divided into two independent processing parts, the electrode body and the joint. Electrode … Read more
