Precautions during the storage process of carbon material raw materials

(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces

Several use of graphite stick products

1. As a conductive raw material applicationWhen using an arc furnace or ore electric furnace smelting plant, a variety of carbon steel, non -ferrous metals or production of carbonized (calcium carbide), and yellow phosphorus, strong current volume according to the electrode of the carbon plant (or continuous self -baking electrons-- - That is, the electrode paste) or the high -purity graphic electrode to introduce the smelting area of the electric furnace, which causes the electromagnetic loneliness, so that the electromagnetic can be converted into energy, and the temperature rises to up to 2,000 degrees Celsius, which will exceed the smelting plant or the regulations reflected.2. Application of refractory insulation materialsBecause charcoal and graphite products can resist heat and have good high temperature pressure resistance and corrosion resistance, many metallurgical industry furnaces can be built with charcoal to build walls, such as the bottom of the furnace, the furnace tan

Classification of graphite

Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electrochar, carbon fiber, special graphite, graphite heat exchanger, etc. according to their usage. Graphite electrodes can be classified into ordinary power graphite electrodes based on the allowable current density. High power electrode, ultra high power electrode. Carbon blocks can be divided into blast furnace carbon blocks, aluminum carbon blocks, electric furnace blocks, etc. according to their purpose. Carbon products can be divided into carbon products, graphite products, carbon fibers, and graphite fibers according to the processing depth. Carbon products can be divided into graphite products, carbon products, carbon fibers, special graphite products, etc. according to different raw materials and production processes. Carbon products can be divided into multi ash products and low ash products (with ash content less than 1%) based on their ash content.The national an

The research progress of battery material, new battery material

As the core component of new energy vehicles, the performance and stability directly affect the use of the vehicle. Therefore, the development of more secure and environmentally friendly battery materials has become an important research direction for the new energy vehicle industry. The battery is a wide range of energy sources, and now it has become one of the infrastructure of modern life. Compared with traditional batteries, modern batteries have better performance, longer life and smaller size. However, the improvement of this performance is inseparable from the progress of battery materials.1. Research on sodium ion battery materialThe sodium ion battery has become a new type of battery due to rich resources and low cost. The electrode material of the sodium ion battery is similar to the lithium battery, but the ion radius of the sodium ion battery is greater than lithium, which causes the transmission performance of the charge in the material to be greatly reduced. Therefore, t

Impregnation object and type of impregnating agent

In carbon products, there are several types of products that need to be impregnated:(1) Products with higher density, mechanical strength, and lower resistivity are required. Such as ultra-high power electrodes, various joint blanks, graphite anodes, mechanical carbon products, etc.(2) Impermeable graphite required for chemical equipment. For example, heat exchangers, pumps, chemical pipelines and fittings, sealing rings and sealing rings used on chemical equipment, etc.(3) Products used for producing wear-resistant materials. For example, piston rings, bearings, directional rings, sliding electrical contacts, etc.(4) Products with special requirements. Such as high-density and high-strength graphite.The commonly used impregnating agents include asphalt, synthetic resins, metals, lubricants, inorganic compounds, etc., which can be selected according to the different performance requirements of the impregnating object. When selecting impregnating agents, it is necessary to pay attentio

Development of Expandable Graphite

Graphite crystal has a hexagonal network plane layered structure composed of carbon elements. The carbon atoms on the layer plane are bound by strong Covalent bond, while the layers are bound by Van der Waals force force. The binding is very weak, and the distance between layers is large. Therefore, under appropriate conditions, acid, alkali gold, salt and other chemicals can be inserted into the graphite layers, And combine with carbon atoms to form a new chemical phase - Graphite intercalation compound (GIC). When heated to an appropriate temperature, this interlayer compound can instantly and rapidly decompose, producing a large amount of gas, which makes graphite expand along the axis into a new worm like material, namely expanded graphite. This unexpanded Graphite intercalation compound is expandable graphite.Expandable graphite was first discovered by Schaufautl, a German. In 1841, Schaufautl soaked natural graphite in a mixture of concentrated HNO3 and concentrated H2SO4, and t

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
