product description:

The vacuum aluminized crucible mainly needs to be impregnated (impregnated with aluminum phosphate), in order to increase the impermeability of the crucible and reduce the porosity. The crucible will burst during use. The main reason is that the porosity of the material is large, and the molten aluminum penetrates into the pores, which will cause the crucible to rupture during continued use.

The selected material for graphite crucible is high-purity graphite. High-purity graphite is widely used in various industries such as casting, metallurgy, and mold. Moulds; graphite moulds for metallurgical industry and other graphite finished parts of various shapes and uses can be realized, and the demand for graphite with processing accuracy and roughness can be realized.

Graphite crucible performance:

1. Thermal stability: According to the use conditions of rapid heating and rapid cooling of graphite crucible, special design is made to ensure the reliability of product quality.

2. Corrosion resistance: The uniform and fine matrix design delays the corrosion degree of the crucible.

3. Shock resistance: The thermal shock strength that the graphite crucible can withstand is extremely high, so any process treatment can be carried out with confidence.

4. Acid resistance: The addition of special materials can significantly improve the quality of the crucible, and it has excellent performance in acid resistance indicators, and greatly prolongs the service life of the graphite crucible.

5. High thermal conductivity: The high content of fixed carbon ensures good thermal conductivity, shortens the dissolution time, and significantly reduces fuel consumption or other energy consumption.

6. Control of metal pollution: strict control of material composition ensures that the graphite crucible does not pollute the metal during dissolution.

7. Quality stability: The production technology and quality assurance system of the high pressure forming method more fully guarantee the quality stability. , Welcome to processing with drawings and samples, and please tell us the working conditions of the products you need, we will choose suitable materials for you and provide satisfactory products and services.

Graphite crucibles are widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical and other industrial sectors because of the above excellent properties. And has better technical and economic effects.

Instructions for using crucible products:

1. The graphite crucible should be protected from moisture and must be stored in a dry place or on a wooden shelf.

2. When handling, handle with care, and it is strictly forbidden to shock.

3. Before use, it needs to be heated by drying equipment or furnace, and the temperature is gradually raised to 500 ℃.

4. The crucible should be placed below the plane of the furnace mouth to avoid the furnace cover from wearing the crucible upper mouth.

5. When adding material, it should be based on the melting capacity of the crucible, do not add too much material, and avoid expanding the crucible if it is too tight.

6. The furnace tool and crucible clamp should conform to the shape of the crucible, and the middle part of the clamp should be clamped to avoid damage to the crucible by local force.

7. When removing molten slag and coke from the inner and outer walls of the crucible, tap lightly to avoid damage to the crucible.

8. An appropriate distance should be maintained between the crucible and the furnace wall, and the crucible should be placed in the center of the furnace.

9. Excessive use of accelerants and additives will reduce the service life of the crucible.

10. During use, turn the crucible once a week to prolong the service life of the crucible.

11. Avoid direct injection of strong oxidizing flame to the sides and bottom of the crucible
