Usual dimensions include heights of 50-200 mm and sizes of 30-150 mm, though bespoke sizes are available. The smooth indoor surface area helps with very easy slag elimination and cleansing, while the wearless style makes certain minimal material loss in time, reducing substitute regularity.

Applications cover factories, metallurgical labs, and high-temperature research study, especially for melting iron, steel, copper, and nickel alloys. Compatible with electric, induction, and gas heating systems, it suits aerospace, automobile, and fashion jewelry industries. The crucible’s longevity, paired with resistance to thermal tiredness and chemical disintegration, makes it a cost-efficient option for requiring atmospheres. Packaged in shock-resistant materials, each system undertakes strenuous quality checks to fulfill commercial requirements. This alumina crucible combines precision design with robust efficiency, providing reliability for essential melting operations.

5 FAQs of Alumina Crucible Iron Melting Quality Porcelain Alumina 99.5% Wearless Ceramic Crucible

**What is the maximum temperature this alumina crucible can withstand?**
The Alumina Crucible (99.5% purity) is designed for high-temperature applications, withstanding continuous use up to 1750°C (3182°F) and short-term exposure to 1800°C (3272°F). This makes it ideal for iron melting, which typically requires temperatures around 1500–1600°C. Its superior thermal stability ensures minimal thermal expansion, reducing the risk of cracking under extreme heat.

**Is this crucible resistant to thermal shock?**
Yes, the 99.5% alumina composition provides excellent thermal shock resistance. It can endure rapid temperature changes, such as transferring from a hot furnace to a cooler environment, without cracking. However, gradual preheating (200–300°C per hour) is recommended before initial use to maximize longevity and performance, especially in demanding applications like iron melting.

**How does the alumina content affect durability?**
The 99.5% high-purity alumina ensures exceptional mechanical strength and wear resistance. This minimizes erosion, corrosion, or contamination from molten iron, slag, or fluxes. The dense ceramic structure prevents metal penetration, extending the crucible’s lifespan even under repeated use. Lower-purity crucibles may degrade faster, but this grade maintains integrity in harsh metallurgical environments.

**Can this crucible be reused multiple times?**
Yes, it is reusable if handled carefully. Its wear-resistant properties allow it to endure multiple melting cycles. Avoid mechanical impacts or sudden temperature fluctuations between uses. Inspect for cracks or thinning after each cycle—proper maintenance ensures 10–20 uses, depending on operating conditions. For industrial settings, regular inspection is advised to ensure safety and performance.

**How do I clean the crucible after melting iron?**
After cooling, remove residual metal or slag using a soft brush or non-abrasive tool. Soaking in diluted hydrochloric acid (5–10%) can dissolve stubborn deposits, but rinse thoroughly with water afterward. Avoid harsh mechanical scraping, which could damage the surface. Ensure the crucible is completely dry before reheating to prevent moisture-induced cracking during the next use.
