2023-03-221. Heating and conductive: The heterogeneity of graphite is 300 times that of the normal non -non -non -metal mine. Conductivity surpasses non -metal materials such as steel, iron, lead. The conductivity coefficient increased with a decrease in measure, and even at a high degree, graphite became armatologist.2. Chemical stability: Graphite is excellent chemical stability at normal temperature, and the erosion of acid, alkali resistance and inorganic solvents.3. Smooth: The smooth function of graphite originated from the size of the graphite scales. The larger the scales, the smaller the conflict coefficient, and the better the smooth function.4. Plasticity: The graphite is tough and can be crushed into a thin crack. 5. Taxation shock: Graphite can be banned violently at the time of normal temperature and can be banned violently without destruction. When the measurement gradually changes, the volume of the graphite is not large and no cracks will occur.6. Low temperature resistance: T
2023-03-221. 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
2023-03-22What are the choices of is used for refining, and usually the temperature is extremely high. Therefore, the raw materials for manufacturing should have high refractory resistance and have a strong high temperature resistance coefficient. There are also sufficient strength of ingredients. If the impact of high temperature, etc. during the smelting process, there will be wear. Therefore, if the strength of the raw material is not high, it is likely that the more waves will be used, and the more toughness will be lacking. The contraction coefficient must be small, and the temperature changes sharply without deformation and breaks. There must be not to afford the chemical response with the melted metal in the selection of materials, and the high temperature resistance of chemical metals should be high. Loss. When the melting metal is demanded at high temperature, the selection of should ensure that chemical stability at high temperature should be learned. It can be seen that there are a
2023-03-21Pencil, one of the most common stationery in daily life. Many people learn to write and start with the use of the scooter. However, many people do not know that although the pencil contains the word "lead", the current pencil is indeed no lead. Why is this?
2023-03-211. During the use of graphite stick products, the graphite stick products are turned once a week to extend the life of graphite stick products;2. Using an appropriate amount of combustion agent, additives will reduce the life of graphite sticks;3. Keep a proper distance between the graphite stick and the wall of the furnace, and the graphite stick products should be placed in the furnace positive;4. When removing the inside of the graphite rod product, the inside of the wall of the graphite and sticking should be tapped to prevent damage to damaging graphite rod products;5. Graphite products are strictly preventing humidity. They must be placed on a dry place or wooden stand during storage.
