Intermediate Frequency Furnace and Graphite Crucible
In the use of intermediate frequency furnace, some utensils will be used to hold the metal to be melted.
Graphite crucible is a kind of high refractory vessel, used for smelting and casting copper, aluminum, zinc, lead, gold, silver and various rare metals, with high temperature resistance, oxidation resistance.
Sometimes, the graphite crucible is an indispensable part for the IF furnace, and a good graphite crucible can improve the smelting quality of the IF furnace.
Today, Hongteng editor to introduce to you about the selection of graphite crucible of medium frequency electric furnace skills and methods of use and matters for attention.
When choosing, the first thing to pay attention to is the size. We must choose the right size, not too big, not too small, too big or too small will affect the final use.
Now the popular kind is called silicon carbide graphite crucible, is formed by pressing, the crucible quality is generally better than graphite, long service life, fast heat conduction.
Check whether there is a crack in the electric furnace graphite crucible, no matter whether the crack is big or small, will be in the process of use, resulting in the final damage, cracks will not appear in the process of production, in the process of transportation will knock, causing cracks.
Use of graphite crucible for intermediate frequency electric furnace
Installation method of graphite crucible for intermediate frequency electric furnace: Fill the bottom of the furnace with the graphite crucible for intermediate frequency electric furnace horizontally and firmly in the center, and put the filling material into the center in batch, and then 3 people turn around and solidify all around with tools (5 minutes), and then pour 200M/M into the crucible until the completion of continuous operation.
Drying: at the beginning of the furnace at the speed of 200 degrees per hour to use the temperature to maintain this temperature for 3 hours to make the intermediate frequency electric furnace graphite crucible firm.
Melting method: preheat the furnace at low temperature every morning (2 hours before shift) and then put in normal power. The soup time, due to different mixing products, different electric heating curve can not be set, but still try to keep the temperature rising smoothly.
The use of material to make it can be put into the furnace block the bigger the better the goods, do not collide with the intermediate frequency electric furnace graphite crucible, two furnace with a little hot to make it easy to melt new material, do not melt rapidly, if the furnace graphite crucible with molten soup can not be cooled, attached oxide to remove at any time.
In ordinary times, we should store the electric furnace graphite crucible in a dry place to avoid moisture or water. The water may react with the material placed in the crucible under certain conditions.
Avoid collisions or drops from high places. Use caution, pay attention to your surroundings and handle with care. Put material into the crucible gently, impact or drop may cause damage to the product, so that it cannot be used properly.
According to the above operation, the working rate of crucible furnace can be increased, and the working rate of graphite crucible can be increased correspondingly. It can also prolong the service life of graphite crucible of intermediate frequency electric furnace.
This is the knowledge of intermediate frequency electric furnace and graphite crucible that we collate today. I hope it can be helpful to you. Welcome to pay attention to Luoyang Hongteng and learn more about induction electric furnace.
