Graphitelectrodes The measures to reduce the consumption of Graphite Electrodes in LF Furnaces are mainly included in the following aspects. Choose Reasonable Power Supply Parameters 1) The power distribution system of the 50tLF furnace is divided into 11 gears, within the voltage range of 110 ~ 250V, each level increases by 15V. The 60tLF furnace power … Read more
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
Regarding the price of graphite electrodes, whether it is ordinary power products or high-power products, the increase in a certain period of time has exceeded 10%, and the average price can be doubled. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binding agent, calcination, … 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
