Product Description

product description:
Vacuum aluminized crucibles mainly need to be dipped (dipped in aluminum phosphate), the purpose is to increase the impermeability of the crucible and reduce the porosity. The crucible will explode during use. The main reason is that the material has a large porosity, and the aluminum liquid 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 casting, metallurgy, molds and other industries. High-precision CNC machining equipment makes the production level. High-purity, high-strength, high-density graphite crystallizer for continuous casting; graphite for electronics industry Molds; graphite molds and other graphite processed finished parts of various shapes and purposes can be realized in the metallurgical industry, and the demand for graphite with processing accuracy and roughness can be realized.
Technical Characteristic:


Graphite crucible performance:
1. Thermal stability: According to the use conditions of graphite crucible for rapid heating and cooling, special design is carried out to ensure the reliability of product quality.
2. Corrosion resistance: The uniform and fine matrix design delays the corrosion of the crucible.
3. Impact resistance: The thermal shock strength that the graphite crucible can withstand is extremely high, so any process 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 terms of acid resistance, and greatly extends 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 the 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 stability of the quality. , Welcome to process with drawings and samples, and please tell us the working conditions of the products you need, we will choose the right materials for you, and provide you with satisfactory products and services.
Graphite crucibles are widely used in the smelting of alloy tool steels and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical and other industrial sectors due to the above-mentioned excellent properties. And has a good technical and economic effect.

Instructions for using crucible products:
1. The graphite crucible must be kept away from moisture and must be stored in a dry place or on a wooden shelf.
2. Handle with care when transporting, and it is strictly forbidden to drop and shake.
3. Before use, it needs to be baked in drying equipment or furnace, and the temperature is gradually increased to 500 ºC.
4. The crucible should be placed below the surface of the furnace mouth to prevent the furnace cover from wearing the upper mouth of the crucible.
5. When adding materials, it should be based on the melting amount of the crucible, do not add too much material, and avoid expanding the crucible if it is too tight.
6. Furnace tools and crucible clamps should conform to the shape of the crucible, and clamp the middle part to avoid damage to the crucible by local stress.
7. When removing molten slag and coke on the inner and outer walls of the crucible, tap it to avoid damage to the crucible.
8. A proper distance should be kept between the crucible and the furnace wall, and the crucible should be placed in the middle of the furnace.
9. Excessive use of combustion aids and additives will reduce the service life of the crucible.
10. During use, rotate the crucible once a week to extend the service life of the crucible.
11. Avoid direct injection of strong oxidizing flame on the side and bottom of the crucible
