Overview of Silicon Carbide Crucible

Silicon carbide (SiC) crucibles are advanced ceramic vessels known for their exceptional thermal conductivity, high strength, and resistance to thermal shock. These crucibles can withstand extreme temperatures up to 1600°C and are highly resistant to chemical attack, making them ideal for melting metals, alloys, and other materials in both laboratory and industrial settings.

Features of Silicon Carbide Crucible

High Thermal Conductivity: Efficient heat transfer ensures uniform heating and rapid temperature changes.

Thermal Shock Resistance: Can endure rapid temperature fluctuations without damage.

Chemical Inertness: Resistant to most acids and alkalis, minimizing contamination.

Temperature Range: Operates effectively at temperatures up to 1600°C.

Mechanical Strength: Extremely durable and strong, even under harsh conditions.

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

Long Service Life: Durable construction ensures extended use and reliability.

Specification of 100-1000kg large capacity smelting furnace graphite crucibles silicon carbide crucible for melting meta

Our large capacity graphite crucibles are built for melting metal efficiently. They handle loads from 100kg to 1000kg. These crucibles combine graphite with silicon carbide. This mix creates exceptional strength. High temperatures pose no problem. They withstand intense heat without damage. Thermal shock resistance is a key feature. Sudden temperature changes won’t crack them. This durability means longer service life. You replace crucibles less often. That saves money over time.

These crucibles work with many metals. Melt gold, silver, copper, iron, or aluminum easily. Foundries rely on them daily. Recycling operations use them too. The smooth interior surface ensures clean pours. Metal flows out without sticking. Maintenance stays simple. Just clean after each use.

Different sizes cover various needs. Small workshops pick 100kg models. Big industrial plants choose 1000kg versions. All sizes share the same rugged construction. They resist chemical corrosion from molten metal. Slag buildup minimizes. That keeps your melting process efficient. Heat distributes evenly inside. This prevents hot spots. Your metal melts uniformly every time.

Handling is straightforward despite their size. Reinforced rims prevent chipping. Special lifting tools fit securely. Safety during operation is a priority. These crucibles meet strict industry standards. They perform reliably batch after batch. Production delays reduce. Your metal casting becomes more productive.

Choose these graphite crucibles for heavy-duty melting. They deliver consistent results under pressure. Work with confidence knowing your equipment won’t fail.

Applications of 100-1000kg large capacity smelting furnace graphite crucibles silicon carbide crucible for melting meta

These big graphite crucibles handle heavy melting jobs. They work in furnaces melting 100 to 1000 kilos of metal at once. You need strong crucibles for this much metal. These crucibles are tough. They handle very high heat well. They also resist thermal shock. Sudden temperature changes won’t crack them easily. This makes them reliable for demanding factory work.

They melt many metals. Iron and steel foundries use them constantly. They are good for brass, bronze, and aluminum too. Precious metal recyclers use them for large batches of gold or silver scrap. Scrap yards melt down big loads of copper or other non-ferrous metals in them. These crucibles are built for heavy, daily use.

Their size saves time. You melt more metal in one go. You don’t need to stop the furnace as often to refill. This speeds up production. Foundries making big castings rely on this capacity. The crucibles are stable holding that much molten metal. Workers feel safer handling them.

Silicon carbide graphite crucibles are especially tough. They last longer under extreme conditions. They resist chemical attack from slag or fluxes better. You get more melts before replacing them. This saves money over time. They are a good choice for aggressive melts or very high temperatures.

Handling requires care. Use proper lifting tools designed for heavy crucibles. Follow the preheating steps carefully. Avoid sudden impacts when moving them. Check for wear regularly. Replace crucibles showing cracks or bad erosion. Proper care extends their life.

5 FAQs of 100-1000kg large capacity smelting furnace graphite crucibles silicon carbide crucible for melting meta

FAQs for Large Capacity Smelting Crucibles (100-1000kg)

What size crucible do I need?
Match the crucible capacity to your furnace and metal batch size. Crucibles hold 100kg, 250kg, 500kg, 750kg, and 1000kg. Choose a size fitting your furnace chamber. Leave space above the molten metal. This prevents overflow. Consider the weight your furnace lift can handle.

Graphite or Silicon Carbide? Which is better?
Both handle large melts. Graphite conducts heat well. This means faster melting times. It resists thermal shock decently. Silicon carbide is harder. It lasts longer under harsh conditions. It withstands higher peak temperatures. Silicon carbide costs more upfront. Graphite costs less initially. Your metal type and furnace operation matter most.

What temperature can these crucibles handle?
Maximum temperatures vary. Check the specific crucible rating. Standard graphite handles around 1600-1800°C. Silicon carbide handles higher, often 1600-1650°C consistently. Some reach 1800°C briefly. Never exceed the maker’s stated maximum. Overheating damages the crucible fast. It becomes unsafe.

How long will a large crucible last?
Lifespan depends heavily on use. Factors include temperature, metal type, cycle frequency, and handling. Melting aggressive alloys shortens life. Thermal cycling stresses the material. Proper preheating helps. Expect dozens to hundreds of melts. Inspect crucibles often. Look for cracks or thinning walls. Replace damaged crucibles immediately. Safety is critical.

How do I handle and install these heavy crucibles?
Use proper lifting equipment. Crucibles over 100kg require machinery. Forklifts or overhead cranes are essential. Ensure lifting tools fit the crucible lugs securely. Place the crucible carefully inside the furnace. Make sure it sits level and stable. Follow the maker’s installation guide exactly. Uneven support causes cracks. Handle with care always.
