Graphite

One of the main purposes of graphite is to produce refractory materials, including refractory bricks, crickets, continuous casting powder, molding cores, mold casting, detergent and high temperature resistance. In recent years, the two important changes in the refractory material industry are that magnesium carbon bricks are widely used in the inside of the steelmaking furnace, and the application of aluminum carbon bricks in continuous casting. The refractory material for graphite is closely connected to the steelmaking industry, and the refractory material consumed by the steelmaking industry around the world.Because graphite has many excellent performance, it has been widely used in industrial departments such as metallurgy, machinery, electrical, chemicals, textiles, and national defense. Can be used as refractory materials. Graphite products maintain the chemical characteristics of the original scales graphite and have strong self -lubrication performance. The characteristics of

The Future Market Prospects of Graphite Powder

Which raw materials are selected for the production of graphite electrodes

(1) Raw materials for the production of artificial graphite electrodes. All low ash raw materials such as petroleum coke and asphalt coke can be used to produce high-quality graphite electrodes. Adding asphalt coke is to improve the strength of the product. The production of ordinary power graphite electrodes can use ordinary quality petroleum coke as raw material; Produce high-power graphite electrodes using high-quality petroleum coke and some needle coke; To produce ultra-high power graphite electrodes, high-quality needle coke must be used as the raw material. To produce high-purity graphite electrodes, petroleum coke with very low ash content is required. In order to improve the lubricity and plasticity of the paste and improve the conductivity of the product, a portion of graphite chips is also added to the production ingredient of graphite electrodes.(2) Raw materials for the production of natural graphite electrodes. Using selected natural graphite as raw material and coal tar

Antioxidant treatment method for battery specific graphite

The antioxidant treatment process of battery specific graphite includes material preparation, weighing, impregnation solution preparation, impregnation electrode treatment, and drying treatment. After graphite electrode treatment, it can be processed into various specifications of graphite electrode products. The treated graphite electrode is the same as the untreated graphite electrode. Compared with graphite electrodes, it has the characteristics of smooth surface and good conductivity. The mechanical design strength can be increased by 50-60%, the porosity gradually decreases by 10-15%, and the electrode material consumption can be reduced by 20-25%. Electrode consumption can be reduced by 20-25%.The antioxidant treatment of battery specific graphite has the following properties:(1) Preparation material weighing: Weigh the graphite electrode and provide qualified materials to be processed;(2) Preparation and heating of impregnation solution: The composition of impregnation solution

Factors affecting the impregnation effect

The factors that affect the impregnation effect include: firstly, the impregnation process conditions (such as temperature and pressure), and secondly, the physicochemical properties of the impregnation.Influence of process conditions(1) Temperature (product preheating temperature, impregnation tank temperature, impregnation agent temperature), depending on the impregnation process: 1. The product is preheated too high and is prone to oxidation; The temperature is too low, and when it comes out of the preheating box, it quickly cools down and enters the impregnation tank. When the impregnating agent encounters cold products, its viscosity increases and its fluidity deteriorates, resulting in poor impregnation effect. 2. If the tank temperature is too high, asphalt is prone to oxidation condensation reaction, viscosity will also increase, and flowability will deteriorate; The tank temperature is too low, the fluidity of asphalt is also poor, and the impregnation effect is not ideal.(2)

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

How to distinguish whether Gwangba is clean and tidy?

1. Determine that the graphite boat has no acid and alkali ingredients. (After immersion, you can use pH to detect water or graphite boats that have been used as neutralized to determine the results of the cleaning.)2. Check out the surface layer, graphite guarding point and graphite boat, and whether there are residues of silicon nitride.3. Try the ceramic stick and porcelain sleeve with the dust -free paper -free paper -free paper -free paper.Remarks: The above rules are distinguished under the processing process of all normal washing boats. When the ceramic stick is broken during the whole process of laundering, the insistence is too large, and it needs to be immediately disassembled to prevent everything that endangers the graphite boat. Normal application.
