Overview of Corundum Crucible

Corundum crucibles, made from alumina (Al₂O₃), are highly valued for their exceptional thermal resistance and chemical stability. These crucibles are ideal for high-temperature applications, such as melting and annealing processes in laboratories and industrial settings. Corundum crucibles can withstand temperatures up to 1800°C and are resistant to most chemical reagents, making them indispensable in various scientific and manufacturing operations.

Features of Corundum Crucible

High Thermal Resistance: Can withstand temperatures up to 1800°C without degrading.

Chemical Stability: Resistant to most acids and alkalis, ensuring minimal contamination during experiments or production.

Durability: Extremely durable and long-lasting, even under harsh conditions.

Non-Reactive: Does not react with the materials being processed, preserving sample purity.

Versatility: Suitable for a wide range of applications including melting metals, glass, and ceramics.

Precision Engineering: Manufactured to tight tolerances for consistent performance and reliability.

Specification of 200ml Corundum-mullite Alumina Crucible For Melting Steel

This 200ml crucible handles melting steel. It uses special materials. The main material is alumina. Alumina is very strong and heat resistant. Crucibles need this. The mix includes corundum and mullite too. These add extra strength. They help the crucible last longer. This mix fights steel corrosion well. Steel melt is harsh. The crucible doesn’t react much with it. This keeps the steel pure.

The crucible handles extreme heat. Its refractoriness is very high. It can manage temperatures over 1700°C easily. Steel melts around 1500°C. This gives a safe margin. Sudden temperature changes happen. The crucible resists thermal shock well. Heating or cooling quickly is less risky. It won’t crack easily.

The capacity is 200 milliliters. This is a good size for small batches. It suits lab work or testing alloys. The crucible shape is standard. It has a wide base. The base gives stability. The sides taper slightly upwards. This shape helps pouring molten metal. The crucible works well in induction furnaces. It also works in resistance furnaces. Its design ensures even heating.

The wall thickness is strong enough. It provides good insulation. This thickness supports the material inside. The crucible withstands the weight of molten steel. Its physical strength is high. It resists mechanical stress during use. Handling requires care. Always use proper tongs. Avoid impacts when hot or cold. Inspect the crucible before each use. Look for cracks or chips. A damaged crucible is unsafe. Store it in a dry place. Moisture can weaken it over time. Pre-heat the crucible slowly. This step is important. It removes any moisture. It also reduces thermal shock risk. Follow the recommended heating schedule for your furnace. This crucible offers reliable performance for melting steel. It provides good value for demanding applications.

Applications of 200ml Corundum-mullite Alumina Crucible For Melting Steel

This 200ml corundum-mullite alumina crucible handles tough jobs like melting steel. Its high alumina content, around 70%, gives it serious strength. This material stands up to extreme heat, easily managing temperatures over 1600°C. Steel melts need this kind of heat resistance.

The mix of corundum and mullite is key. It makes the crucible tough against sudden temperature changes. You heat it fast, you cool it down fast, it holds up. This thermal shock resistance matters for daily furnace use. Crucibles crack less often.

Chemical resistance is another big plus. Molten steel and its slag attack many materials. This crucible fights back well. It resists corrosion from iron oxides and common fluxes. Your melt stays cleaner. Crucible life gets longer.

Its size, 200ml, is practical. It fits small furnaces perfectly. You use it for melting precise amounts of material. Think small batches of specialty steel. Think alloy testing. Think precious metal recovery. Jewelers find it handy for small gold or silver melts too. It works well for research labs needing controlled experiments.

The crucible keeps its shape under the intense heat and weight of liquid steel. It doesn’t slump. It doesn’t react badly with the melt. This stability is crucial for getting consistent results. You avoid contamination. Your metal purity stays high.

Handling is straightforward. Its size makes it easy to move, even when hot. It fits standard tongs. This reduces accidents. Safety improves. The smooth surface helps with slag removal after pouring. Cleanup is easier.

For small-scale steel melting, this crucible offers real value. It handles the heat. It resists the chemical attack. It lasts through thermal cycling. You get reliability for demanding applications without needing a giant setup. It’s a solid tool for precise, high-temperature work.

5 FAQs of 200ml Corundum-mullite Alumina Crucible For Melting Steel

What’s the highest temperature this crucible can handle?
It safely handles temperatures up to 1700°C. This is hot enough for melting most common steels. Don’t push it beyond this limit. The crucible could break suddenly.

Do I need to preheat the crucible before use?
Yes, you absolutely must preheat it. Put the cold crucible straight into a hot furnace. This causes thermal shock. It will likely crack. Heat it slowly first. Do this every time.

How many melts can I do with one crucible?
It depends heavily on your specific process. The steel type matters. The melting temperature matters. How you handle the crucible matters. Expect 5 to 15 uses typically. Look for cracks or serious wear. Stop using it then.

Can it hold a full 200ml of molten steel?
No, never fill it completely full. Leave space at the top. Fill it only about 80% maximum. Molten metal expands. It can bubble and splash. Filling it too much risks overflow and accidents.

How should I cool the crucible down after melting?
Let it cool down very slowly. Don’t put the hot crucible on a cold surface. Don’t expose it to cold drafts. Sudden cooling causes cracks. Place it in a warm area instead. Let the temperature drop naturally over hours.
