Graphite is soft, black and gray; greasy, polluting paper. The hardness is 1~2, and the hardness increases to 3~5 with the increase of impurity in the vertical direction. The specific gravity is 1.9 ~ 2.3. The specific surface area is concentrated at 1-20m2/g, and the melting point is above 3000 degrees under the condition of oxygen isolation. It is one of the most temperature resistant minerals. It can conduct electricity and conduct heat. According to these characteristics, graphite products are widely used in the following industry areas: 1, refractory material: graphite and its products have the properties of high temperature resistance, high strength, in the metallurgical industry is mainly used to manufacture steel commonly used in graphite crucible, graphite as…
In general, the graphite crucible before using the inspection work, should do the following main points: 1. first of all, to check whether there is a crack in the graphite crucible before work, no cracks need to heat the graphite crucible to more than 600 degrees C and fully dry. 2. water around a stove and furnace before the pit, near the graphite crucible do not stack irrelevant articles. 3. strict inspection charge no explosives, add burden must be preheated and ensure drying, adding graphite crucible slower. Graphite crucible before use, we must do the above points, otherwise it is likely to lead to the graphite crucible in use when the explosion risk. The main purpose of the experimental material…
