Instructions for use:
1, in a dry, warm place or wooden palate
2. There is no stock in another person
3, don't roll the crucible
4, using the Clama fiber blanket seal, the side of the cover and the stove
5. Use positioning bricks in the inclined furnace to expand the gap
6, cut off the fire around the crucible
7, add flux after metal
8, by ensuring the stove drainage hole seal, avoid failure of the early rinse
For stripping, the pliers must be placed on the lower third of the 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 centered on the crucible
12. Use the pliers and ingots to be carefully placed in the crucible. Advanced technology
Crucibles are manufactured by the world's most advanced cold isostatic molding method, with isotropic properties, high density, high strength, dense, uniform, and defect-free
Great variety of goods
Produce resin bond and clay bond crucible, provide the best solution for different customers, to extend the service life
Long life
Crucible life is 2-5 times longer than ordinary
Resistance to chemical attack
Advanced materials and glaze recipes are effectively resistant to chemical erosion
High thermal conductivity
Using natural graphite materials and isostatic pressing, a thin crucible wall for fast heat conduction
Resistance to high temperature
Crucible temperature range 400-1400ºC
Energy-saving
A crucible made of a high thermal conductivity material can bring a large number of energy savings for users in the production process.
Less pollution
Because of the choice of high-purity inorganic material, little or no harmful impurities are introduced into products in the metal melting process
Good oxidation resistance
The appearance of a crucible has multi-special glaze layers, coupled with the 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 are used, mainly using imported raw materials. The quality is stable and reliable. PREHEATING PROCEDURE OF THE CRUCIBLE USED FOR THE FIRST TIME
1. After the crucible is put into the furnace, it 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 an 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 line.

THE 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 the metal is molten or excessive use of flux
Certain fluxes contain corrosion substances
Fuel containing corrosive substances
Abnormally high-temperature operation may result in a glaze layer smelting resembling corrosion
Top problems
Repeatedly, the top is impacted on the top area, causing oxidation
Slage accumulated around the top area or between the top area and the furnace cover
Small gap between the top and the furnace cover, low temperature in the top area
Contacting with some materials with larger heat exchanging coefficients
Excentral installation causes not enough space between the top and the facade
Excessive oxidation
Flame in the furnace against the bottom of the crucible directly. Low temperature in the top area
Overheated working temperature. Hoisting or moving damaged glass improperly damages the glaze
The emergent drain hole is open
Exliosion
Heating rapidly while the crucible has damped during transportation and storage
Over rapid heating during the preheating procedure
The added materials are not completely dry
Middle or bottom cracks
Lmpacted during transportation or installation
The crucible should be placed in the middle of the furnace stack smoothly and stably
An improper graphite stand is used
The existence of a great thermal difference in the furnace
Matel ingots in the crucible are filled horizontally or diagonally. Metal materials overfilled
Leftover slag or molten metal in the crucible
