How are graphite electrodes consumed in electric furnace steelmaking?

The consumption of graphite electrodes is mainly related to the quality of the electrodes themselves, as well as to steelmaking operations and processes.(1) Electrode end consumption. Its consumption includes the sublimation of graphite material caused by high arc temperature, as well as the loss of chemical reactions between the electrode end and molten steel and slag. The electrode end consumption is also related to whether the electrode is inserted into the molten steel to increase.(2) Oxidation loss on the outer surface of the electrode. In recent years, in order to improve the smelting rate of electric furnaces, oxygen blowing has been widely used, which has led to an increase in electrode oxidation losses. In general, the oxidation loss on the outer circular surface of the electrode accounts for about 50% of the total electrode consumption.(3) Residual loss of electrodes or connectors. A small section of electrode or connector that is continuously used at the connection between

Several factors of hot pressure graphite mold damage

1. Broken: Graphite mold directly contacts the matrix powder containing diamond. The contact surface is in a high pressure state. The hardness of diamond and graphite mold is too poor. The surface of the mold that is in contact with diamond tool head will produce concave pits.Second, the type of damage: During the sintering process, the matrix powder infiltrates into the oxidation gap of the graphite mold under the melting state, resulting in the adhesion between the tool head and the mold, making it difficult for molding. The repeated attack of the mold can remove the mold, which causes the lack of edges and metal pit in the mold.Third, the wear size of graphite molds is very poor: some substrate powder will be squeezed out of the mold surface in the melting state to attach to the graphite material. Before using the mold next time, metal residues must be removed manually, which causes the shape and size of the mold to exceed the tolerance.Fourth, surface oxidation and cracking: Becau

Differential needs of scales graphite in different fields

There are many types of domestic scale graphite resources and rich features, but the current domestic graphite mine resources are relatively simple. It mainly found that the natural types of ore, ore taste, main minerals and pulse ingredients, optionality, etc. It is simple, focusing only on the crystal shape of the crystal, the amount of carbon, sulfur content, and scales. Although there are huge differences in the characteristics and quality of graphite ore and fine powder in each scale graphite, they are not distinguished at all from the sperm powder logo. The classification system simply brings the high degree of homogeneity of the upstream raw materials of graphite in various places, covering the reality of its reality Application value, the following editors talk to you about the differentiated demand for scales graphite in different fields:This status quo has brought very prominent problems: on the one hand, the lower reaches of the scale graphite is very difficult and blind to

Two ways of formation of scales graphite

The application of scales graphite in the industry is very widely used, and it plays a pivotal role. my country is one of the countries with rich scales in the world in the world. So how does the scales graphite ore formed? Two causes of biology, the following editors will explain the two formation methods of scales graphite for everyone:1. Bio -graphite biological causesBiological causes refer to the scales graphite directly from organic matter, commonly in marble, sliced rocks, or hemp rocks. Coal seams or carbon -containing sedimentary rocks can form scales graphite. It is the metamorphic mineral of graphite, which is made of organic or charcoal.Second, the non -biological cause of graphiteNon -biological causes refer to the reducing carbon out of CO and CO2. In the contact zone between magma rocks and limestone, scales are often produced. This is due to the decomposition of carbon dioxide by limestone and degenerate. The formation of mineral beds must concentrate and have suitable

Do you know the difference between carbon felt purification and graphite felt?

Carbon felt is a felt made of carbon fiber, which has a wide absorption spectrum and a large capacity. Graphite felt can be made by high temperature graphitization. Graphite felt is mainly used as thermal insulation material for monocrystalline silicon smelting furnace.Carbon felt purification can be used as adsorption purification material, as insulation material for vacuum furnace and inert gas furnace. In addition, carbon fiber materials have advantages in fields that have strict requirements on strength, stiffness, weight, fatigue characteristics, etc., and in occasions that require high temperature and high chemical stability. The carbon content is about 90%, and the service temperature is about 1000 degrees Celsius.The main use of graphite felt is as insulation material for monocrystalline silicon smelting furnace. It can be used as a filter material for high-purity corrosive chemicals in the chemical industry. Under the condition of non-oxidizing atmosphere, the service tempera
