About the furnace, the selection and use of graphite crucible
In the metal thermal processing industry, graphite crucibles are used for smelting and casting copper, aluminum, zinc, lead, gold, silver and various rare metals when heated by electric furnaces.
Graphite crucible is a kind of refractory vessel, which has the characteristics of high temperature resistance and oxidation resistance. It is an indispensable accessory for intermediate frequency electric furnaces. A good graphite crucible can directly improve the melting quality of electric furnaces.
How to choose electric furnace graphite crucible? Today, the editor of Hongteng will share with you some methods for selecting graphite crucibles for intermediate frequency electric furnaces.
When choosing, the first thing to pay attention to is the size of the crucible, neither too large nor too small, otherwise it will affect the normal use of the crucible.
Choose the appropriate crucible material, there are many types of graphite crucibles, silicon carbide graphite crucibles are more popular now. This kind of crucible is manufactured by pressing and forming process, the quality is generally better than that of graphite, the service life is long, and the heat conduction is fast.
After we choose a suitable crucible, we also need to check many aspects when using it.
For example, check whether there are cracks on the surface of the graphite crucible. When using crucibles, the effect of cracks is very large, and some cracks can even cause damage to the crucible.
Under normal circumstances, cracks do not appear during the production process, but are bumped during transportation, causing cracks.
Therefore, when we use the crucible, we must also be careful and pay attention to the surrounding environment. Handle it with care, impact or drop may cause the product to be damaged and make it unable to use normally.
In normal times, we should store the electric furnace graphite crucible in a dry place to avoid moisture or water.
Moisture may react with the material in the crucible under special conditions, affecting the properties of the material. If it is in the experiment, the results of the experiment will have a large deviation, and the moisture will also affect the performance of the crucible, and affect the efficiency and process of the entire production.
This is what we share today about electric furnace graphite crucibles, I hope it can be helpful to you. Welcome to Luoyang Hongteng, let us provide you with more furnace services.
