JX Isostatic graphite  has the features of high purity, good machining capability, high compressive and bending strength, low resistivity, high temperature resistant, oxidation and corrosion resistant. High-purity graphite is widely used in making EDM (Electronic Discharge Machine) electrodes, diamond sintering molds, continuous molding mould, crystal over heater, etc.

Instructions for use

1.The crucible should be stored in ventilated and dry environment to avoid damp.

2.The crucible should be handled with care, and it is strictly forbidden to shake or roll, so as not to damage the protective layer on the surface of the crucible.

3.Before use, the crucible should be roasted in advance, and the baking temperature should be gradually increased from low to high, and the crucible should be constantly turned over to be heated evenly, to evaporate the water in the crucible body, and the preheating temperature should be gradually increased to over 500 (if improper preheating causes the crucible to flake and burst, which is not a quality problem and will not be returned or exchanged)

4.The crucible furnace shall be matched with the crucible, the upper and lower and surrounding voids shall meet the requirements, and the furnace cover shall not be pressed on the crucible body.

5. The flame should be sprayed on the base of crucible when in use, and the crucible body should be avoided7. from direct flame spraying.

6.Charging must be slow, and do not charge too much, too tight, so as not to crack the crucible.

7.The crucible tongs used for loading and discharging should match the shape of the crucible so as not to damage the crucible.

8.The crucible is best to be used continuously, so as to better play its high performance.

9.It is necessary to control the dosage of additives in the melting process,overuse will reduce the life of the crucible.

10.The crucible should be knocked gently when removing slag and coking on the inner and outer walls to avoid damaging the crucible.
