Advanced 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 chemical attack 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 reliable |
PREHEATING 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 ºCC 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 °C after half an hour with full heating power, holding for about 1 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 600 ºC 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 |
Instructions for use: 1,Store crucibles in a dry , warm place or wooden palate 2,Do not stock inside another 3,Do not roll crucibles 4,Use creramic fiber blanket to seal , interspace of cover and sides of furnace 5,Use locating bricks in tilting furnaces,to interspace of expansion 6,Tangential fire around crucible 7,Add flux after metal is molten 8,Avoid premature crucible failure by ensuring that the furnace drain hole is sealed 9,For lift-out ,tongs must be placed on lower third crucible . fit tongs evenly on both side 10,Check for cracks or other damage during transporting before use 11,Base block must be flat , larger than crucible bottom and centered 12,Use tongs and ingots should be placed carefully into the crucible |
