Ind-Crucible

Product Description

Silicon carbide graphite crucibles, composed of silicon carbide and graphite, are characterized by low porosity, high density, and uniform texture. They possess excellent thermal conductivity and chemical corrosion resistance, making them indispensable tools in high-temperature applications. They are widely used for melting and refining metals such as gold, silver, copper, aluminum, lead, zinc, zinc oxide, high-purity aluminum, and other alloys.

Silicon carbide graphite crucibles are made by sintering graphite as the base material with varying proportions of silicon carbide particles. The silicon carbide content can be customized to meet specific customer requirements regarding smelting conditions, furnace type, and raw materials.

Core Highlights

1. Advanced Technology: Utilizes isostatic pressing, resulting in excellent isotropy, high density and strength, uniform compactness, and a defect-free finish.

2. Complete Product Range: Offers diverse solutions for different customers, employing the most suitable varieties to meet various needs and extend service life.

3. Long Lifespan: 2-5 times longer than ordinary clay-graphite crucibles.

4. Corrosion Resistance: Advanced formula and high-quality materials effectively resist chemical corrosion.

5. Fast Thermal Conductivity: Employs high thermal conductivity materials, resulting in a dense structure after isostatic pressing, low apparent porosity, and rapid thermal conductivity.

6. High Temperature Resistance: The crucible's operating temperature range is 400-1600℃, with selectable ranges.

7. Energy Saving: Fast thermal conductivity reduces energy consumption and waste emissions.

8. Low Pollution: High-purity inorganic non-metallic materials are used, preventing the introduction of harmful impurities during metal melting.

9. Oxidation Resistance: Advanced formula and the use of imported antioxidant materials enhance the crucible's oxidation resistance.

10. Stable and reliable quality: The main raw materials are all from well-known foreign brands, and all materials have undergone strict inspection; each process in the production process has undergone strict inspection before it can enter the next process.

The crucible can be customized to meet the following customer requirements:

1. Reserve positioning holes for positioning. Diameter 100mm, depth 12mm.

2. A pouring nozzle is required to be installed at the top of the crucible.

3. Add a temperature measuring hole.

4. Drill holes on the bottom or side according to the provided drawings.

FAQ

Q: Slow Heat Conduction

A: 1. Not preheating according to the standard procedure.
2. Slag influences heat conduction.
3. The crucible has reached its service life.
Q: Crucibe corrosion

A: 1. Adding flux before metal is molten or excessive use of flux.
2. Certain fluxes contain corrosion substances.
3. Fuel containing corrosive substance.
4. Abnormal high-temperature operation may result in glaze layer smelting resembling corrosion.
Q: Top problems

A: 1. Repeatedly top impacted on top area cause oxidation.
2.Slags accumulated arround the top area or between the top area and the furnace cover.
3.Small gape between the top and the furnace cover. 4. Low temperature on top area.
5. Contacting with some matels with lager heat exchanging coefficients.
6. Excentral installation cause not enough space between the top and furnace.
Q: Excessive oxidation

A: 1. Flame in furnace against the bottom of the crucible directly.
2. Low temperature in the top area. 3.Overheated working temperature.
4. Hoisting or moving improperly damages glaze layer.
5. The emergent drain hole is open.
Q: Explosion

A: 1.Heating rapidly while the crucible has damped during transportation or storage.
2. Over rapid heating-up during preheating procedure.
3. The added materials are not completely dried.
Q: Middle or bottom craks

A: 1.Impacted during transportation or installation.
2. Crucible should be placed in the middle of the furnace stack smoothly and stably.
3. An improper graphite stand is used.
4. The existence of great thermal difference in the furnace.
5.Matel ingots in the crucible filled horizontally or diagonally.Metal materials overfilled.
6. Leftover slag or molten matal in the crucible.
