In mold industry is developing rapidly, graphite materials, new technology and increasing the mold factories continue to impact the market mold, graphite with good physical and chemical properties gradually become the mold making material of choice. Graphite Mold is widely used in the industrial production of basic technology and equipment, mold industry is the basic industry of the national economy. In modern industrial production, product widely used stamping, forging, die casting, extrusion forming, plastic injection or other processing methods, and forming die matching, the blank forming part in accordance with requirements of the products. Our everyday life and production by the use of various tools and products, to the machine base, the body shell, a small embryo head screws, buttons…
Graphite electrode scrap, refers to the waste after graphitization or after processing carbon products factory production of graphite electrode, graphite electrode and debris processing products when cut off. The export of graphite electrode usually broken, including graphite electrode scrap foundry used in steel factory. Graphite electrode is made of coke and pitch coke as the main raw material, using coal tar pitch as binder, after more than 2000 DEG C high temperature heat treatment. So that the amorphous carbon conversion of graphite and users of a product, mainly in the metallurgical industry in arc furnace as conductive materials, smelting alloy steel, iron alloy, nonferrous metal and rare metal. The main characteristics of the graphite electrode with carbon content in 99%…
The crucible is a bowl shaped container with a deep bottom. The general graphite crucible can not guarantee the safety in the high temperature environment, and the conductive speed is slow so that it is not conducive to the experiment. When a solid is heated by a fire, it is necessary to use a graphite crucible. Because it is more able to withstand high temperatures than glass vessel, the current silicon carbide crucible is widely used. We don’t put too full the melting stuff in the silicon carbide crucible usually when it is used so as to prevent the heat from jumping out and let the air be free to get in and out for possible oxidation reaction. Because the…
