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
The electrode is an important part of the electric furnace and a part of the secondary conductors and terminals. Relying on the electrodes to send the low voltage and large current from the furnace transformer to the furnace, the electric arc at the end of the electrode, the resistance of the charge, and the melt … Read more
In the production of yellow phosphorus produced by the electric furnace method, the consumption of graphite electrodes includes two parts: the normal consumption used to generate electric arc to supply electric energy to melt the charge and participate in the main reaction of reducing phosphorus and iron, and abnormal consumption caused by electrode breakage or … Read more
The main raw material for graphite electrode production is petroleum coke. Ordinary power graphite electrodes can be added with a small amount of pitch coke, and the sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also needed when producing high-power or ultra-high-power graphite electrodes. The following lists the production … Read more
Graphite Electrodes for Electric Arc Furnace are conductor material that the electric arc furnace releases electric energy in the form of an electric arc to heat and melt the charge. Due to the extremely harsh working environment, compared with other conductive materials, graphite electrodes have some excellent or irreplaceable characteristics under high-temperature conditions. For example, … Read more
