Graphite Crucible major components of the natural flake graphite and binder, it is fast thermal conductivity, high temperature resistance, thermal stability, and does not react with melting of the advantages is the casting of non-ferrous metals. However, in an atmosphere of high temperature oxidation-use easily oxidized, in the provision of different heat sources should be avoided when the strong oxidative atmosphere, it will reduce its life.
Flake graphite crucible use:
1. Graphite crucible easy to moisture absorption, and I am afraid wet, in transit, depositors, the process of using prohibited wet, or else the case of furnace heat will burst. If exposed to moisture, the Front should be a searing before use. Drying should be picking up gradually, and the maximum temperature should not exceed 500.
2. Graphite crucible is a fragile materials, used in the handling avoid throw, touch, squatting, trailers, roll with a sharp and hard objects pry blow to clamp top of the crucible, so broken, cracked.
3. Check on the spot under the Crucible is not a crack, defects such as hollow, if can not be used. UNAMSIL's hard not to feed, can not stay cold crucible at the end to avoid the heat after heat expansion Chanlie crucible.
4. Crucible melting after each must be released, the use of curved claws clamp attached to a crucible shape, not local focus. Crucible folder claws to the central crucible, not in the folder, the folder to avoid cracking crucible. Crucible take place grid can not have a hard object at the end of the furnace at the bottom can not be used within the crucible Coke.Crucible furnace in the heater should be less than the face. Crucible in the furnace of the application if tilt with the same curvature and the crucible of iron rake correction, which can not be Qiaoao correction. For additional melting in flux, deterioration, etc. Do not add too much too early, and the crucible acid, alkali and salt from the reaction medium, etch crucible of clearly reduced life. James crucible remove all residue, James Coke taps should be, as far as possible, not exposing graphite layer. Such as the use of intermittent, and can not be put on hold in the crucible in the furnace higher than 30°C the oxidation resistance.
Note:
Crucible furnace on the use, not humid furnace pit water. Melting of not in any liquid or attachment of the explosion to prevent the incidents.
Crucible in the selection, should be the basis of the different melting temperature, different selection of the crucible refractoriness, which will better play Crucible function.
Crucible continuous use than the intermittent use of better results. A different shape and the furnace heat, crucible of life are also different.
