Graphite crucibles are mainly used in auto parts, electronics, and new materials industries. Graphite crucibles are high-temperature vessels that melt and contain ferrous metals and new materials. It can also be used for the refining and purification of non-ferrous metals and new materials. In order to be environmentally friendly, the weight ratio of light metals in industrial products has been greatly increased internationally. Therefore, aluminum, magnesium, zinc, and their alloys are widely used in the production of supporting products for automobiles, motorcycles, and electronics. Such as die-casting production of automobile and motorcycle wheels, engine cylinder heads, brakes, air filters, pistons, radiators, steering wheel skeletons, and mobile phone shells in electronic products.
The main raw material of graphite crucible is crystalline natural graphite, so it has good heat transfer and high-temperature resistance, strong corrosion-resistance to acid and alkaline solutions, and excellent chemical stability. There are many types of graphite crucibles, which are less restricted in the application and can be selected at will. Based on the above excellent performance, graphite crucibles are widely used in metallurgy, casting, machinery, chemical, and other industrial sectors. Pay attention to the following three points when using graphite crucible:
(1) The graphite crucible can be heated directly. It cannot be cooled immediately after heating, remove it with crucible tongs. Do not place it on a cold metal table to avoid it from cracking due to rapid cooling. (2) The crucible has a small bottom. It needs to be placed on a graphite pad or mud triangle when heated. (3) Stir while evaporating; use waste heat to evaporate to dryness when it is nearly dry. Note the above points can extend the life of graphite crucible.
Crucibles can be divided into three categories: graphite crucibles, clay crucibles, and metal crucibles. Among the graphite crucibles, there are three kinds of general graphite crucible, special-shaped graphite crucible, and high-purity graphite crucible. Due to the different surface treatment processes, it can be divided into ordinary graphite crucibles, anti-oxidation coating graphite crucibles (a layer of graphite crucible anti-oxidation coating is added to the graphite crucible), various types of graphite crucibles, due to their performance, use and use conditions Different, the raw materials used, production methods, process technology, and product specifications are also different.
