Types And Characteristics Of Graphite Crucible
Dec 09, 2022
The types of graphite crucibles are explained in detail. Graphite crucibles have obvious characteristics and are widely used. Graphite crucibles for flame heating are mainly used for smelting non-ferrous metals such as copper, aluminum, and alloys. There are countless features and uses of graphite crucibles, and we will briefly list one or two for you here. Due to reasonable design, advanced structure and novel material of graphite crucible, energy consumption is lower than similar furnaces of the same model after testing. Graphite crucibles are widely used in many fields, and the production produces less pollution. Since clean energy such as natural gas or liquefied gas can be used as fuel, there is less pollution. High-purity graphite crucibles for resistance furnaces are mainly used for smelting gold, silver and rare metals. Ceramic crucibles are mainly used in laboratories and the smelting of platinum, gold and rare metals.
The thermal expansion coefficient of graphite crucible is very small, and it has strong strain resistance to extreme heat and cold, strong acid and alkali resistance, and can be applied to heating various liquids; in addition to chemical aspects, graphite crucible is widely used in metallurgy, casting, machinery, chemical industry and other departments have a wide range of uses; the graphite crucible is made of natural graphite raw materials, and it maintains the original excellent characteristics of graphite. It is used to manufacture heating elements and heat shields of vacuum furnaces, and it is also used to manufacture stressed structural parts such as brackets, trays, guide rails, bolts, bearings, fan blades, etc. The application of graphite in vacuum furnaces greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, and stainless steel, reduces costs, improves certain performances of vacuum furnaces, and expands the scope of vacuum furnaces. scope of use. Graphite has good vacuum performance, thermal conductivity, small thermal expansion coefficient, and its strength increases with temperature, which is safe and reliable.
