Factory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleFactory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleFactory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleFactory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleInstructions for use:
1, in dry, warm place or wooden palate
2, there is no stock in another person
3, don't roll crucible
4, using the Clama fiber blanket seal, the side of the cover and the stove
5, use positioning bricks in the inclinant furnace to expand the gap
6, cut-off fire around the crucible
7, add flux after metal
8, by ensuring the stove drainage hole seal, avoid failure of early rinse
For stripping, the pliers must be placed on the lower third crucible. Evenly suitable for pliers on both sides
10, check cracks or other damage before use
11, the base must be flat, larger than the bottom and center of the crucible
12. Use the pliers and ingots to be carefully placed in the crucibleFactory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleFactory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleAdvanced technology
Crucibles are manufactured by the worlds most advanced cold isostaticmolding method, with isotropic properties, high density, high strength, denseuniform and defect-free

Great variety of goods
Produce resin bond and clay bond crucible, Provide the best solution fordifferent customers, to extend the service life

Long life
Crucible life is 2-5 times longer than ordinay

Resistance to chemicalattack
Advanced materials and glaze recipes, effectively resistance to chemicalerosion

High thermal conductivity
Usingnatural graphite materials and isostatic pressing, thin crucible wallfast heat conduction

Resistance to hightemperature
Crucible temperature range 400-1400ºC

Energy-saving
Crucible made of high thermal conductivity material can bring a largenumber of energy savings for users in the production process.

Less pollution
Because of the choice of high purity inorganic material, little or no harmfulimpurities into products in the metal melting process

Good oxidation resistance
The appearance of a crucible has multi-special glaze layers, ciupled withthe molding material compact, greatly improving the corrosion resistance ofthe product, and extending the life of the crucible

Stable and reliable quality
Part of the main raw materials of foreign well-known brands used, glazesmainly using imported raw materials. The quality is stable and reliableFactory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleFactory Direct Graphite Clay/Graphite Silicon Carbide Round CruciblePREHEATING PROCEDURE OF CRUCIBLE USED FOR THE FIRST TIME 
1. After the crucible is put into the furnace, the crucible is heated slowly, and the temperature reaches 200 ºC after two hours to remove the warm gas in the crucible
2. Then the crucible was heated to 600 ºC after 15 hours with low power, and then the temperature was 950 ºC after half an hour with full heating power, holding for about hour. In this way, the glaze layer can be fully melted, the oxidation resistance can be improved, and the maximum service life of the crucible can be ensured
3. Heat preservation for 1 hour before feeding as required
4. The curve is shown in the green line 
THE PREHEATING PROCEDURE FOR REUSING THE CRUCIBLE IS AS FOLLOWS
1. Firstly, the crucible is heated slowly, and the temperature reaches 600ºC after two hours to remove the moisture in the crucible. At the same time, the glaze layer and anti-oxidation coating on the surface of the crucible are fully sintered to prevent oxidation and prolong the service life of the crucible
2. Then continue heating, and make the temperature reach 950 ºC after half an hour.holding for about 1 hour.
3. Heat preservation for 1 hour before feeding as required
4. The curve is shown in the red lineFactory Direct Graphite Clay/Graphite Silicon Carbide Round Crucible

Factory Direct Graphite Clay/Graphite Silicon Carbide Round CrucibleTHE COMMON PROBLEM ANALYSIS

Slow heat conduction
Not preheating according to the standard procedure
Slaq influences heat conduction
The crucible has reached its service

Crucible corrosion
Adding flux before metal is molten or excessive use of flux
Certain fluxes contain corrosion substances
Fuel containing corrosive substances
Abnormal high-temperature operation may result in glaze layer smelting resembling corrosion 

Top problems
Repeatadly top impacted on top area cause oxidation
Slage accumulated arround the top area or between the top area and the furnace cover
Small gape between the top and the furnace coverlow temperature on toparea
Contacting with some matels with lager heat exchanging coefficients 
Excentral installation cause not enough space between the top and fueace

Excessive oxidation
Flame in furnace against the bottom of the crucible directLow temperature in the top area
Overheated working temperatureHoisting or moving improperly damagesglaze lager
The emergent drain hole is open

Exliosion
Heating rapidly while the crucible has damped during transportation on storage
Over rapid heating-up during preheating procedure
The added materials are not completely dried

Middle or bottom craks
Lmpacted during transportation or installation
Crucible should be placed in the middle of the furnace stack smoothly and stably
An improper graphite stand is uesd
The existence of great thermal difference in the furnace
Matel ingots in the crucible filled horizontally or diagonally. Metal materials overfilled
Leftover slag or molten matal in the crucible
