Factory Graphite Crucible Specs

Material and Construction

Our graphite crucibles are made from high-purity artificial graphite. This material gives the crucible solid resistance to thermal shock and chemical rust. The crucible walls are dense and consistent, which assists stop leakages and prolongs life span. Each system is formed under high pressure and baked at high temperatures to ensure structural stability.

Temperature level Resistance

These crucibles can manage continual usage at temperatures approximately 2,000 ° C (3,632 ° F). They stay stable even during fast heating or cooling down cycles. This makes them suitable for melting non-ferrous metals like light weight aluminum, copper, zinc, and precious metals such as silver and gold.

Capability and Measurements

We offer a range of basic sizes, from 100 grams to 50 kilograms melt capacity. Custom measurements are also readily available upon demand. Wall thickness is meticulously adjusted to balance warmth retention and mechanical strength. Every crucible includes clear markings for secure handling and identification.

Performance Includes

The smooth inner surface area lowers steel attachment and makes cleaning less complicated. Low porosity reduces oxidation and metal loss during melting. Thanks to constant quality control, each batch provides trusted performance in foundry, jewelry, and laboratory setups.

Handling and Safety and security

Constantly pre-heat the crucible gradually before complete procedure to prevent breaking. Usage appropriate lifting devices and use protective gear throughout handling. Shop in a completely dry place far from wetness to keep performance and durability. Avoid sudden effects or mechanical stress and anxiety during usage.

Applications of Manufacturing Facility Graphite Crucibles

Steel Melting and Casting

Graphite crucibles are extensively utilized in foundries and metal workshops. They hold molten metal safely throughout home heating. Their high heat resistance makes them perfect for melting light weight aluminum, copper, brass, and other non-ferrous steels. The crucibles keep their form also at extremely heats. This makes certain clean and constant steel pours every time.

Warmth Treatment Processes

In heat treatment, graphite crucibles protect tiny parts from straight flame get in touch with. They aid create a secure setting for annealing, setting, or tempering. Since graphite conducts warmth equally, parts inside the crucible warmth consistently. This decreases bending and boosts end product quality.

Laboratory and Research Usage

Research laboratories rely upon graphite crucibles for sample prep work. They are chemically inert, so they do not react with a lot of acids, bases, or liquified salts. This makes them safe for holding reactive products during high-temperature experiments. Their purity also avoids contamination of sensitive examples.

Recycling Operations

Scrap metal recyclers make use of graphite crucibles to redeem useful steels. Old wiring, engine parts, and electronic waste can be thawed down successfully. The crucibles handle repeated heating & cooling without cracking. This decreases replacement expenses and maintains procedures running efficiently.

Precious jewelry Manufacturing

Artisans and jewelers melt precious metals like gold and silver in graphite crucibles. The smooth inner surface area stops metal loss and enables very easy pouring. Crucibles made for this function are sized specifically to match little batch demands. They support great detail job without wasting material.

Factory-made graphite crucibles provide sturdiness, thermal security, and reliability across numerous markets. Their design balances performance with cost-effectiveness. Customers obtain consistent outcomes whether they run massive manufacturing or small personalized jobs.

5 FAQs of Factory graphite crucible for

Frequently Asked Questions About Our Graphite Crucibles

What is a graphite crucible used for?

A graphite crucible holds and melts metals at very high temperatures. It works well for melting gold, silver, copper, aluminum, and other non-ferrous metals. Foundries, jewelry makers, and metal casting shops use it every day.

Why choose graphite over other materials?

Graphite handles extreme heat without breaking. It conducts heat evenly, so your metal melts faster and more uniformly. It also resists thermal shock better than ceramic or clay crucibles. This means fewer cracks and longer life.

How long does a graphite crucible last?

Life span depends on how you use it. With proper handling and correct temperature control, one crucible can last for dozens of melts. Avoid sudden temperature changes and never drop it. Clean it gently after each use to remove leftover metal or slag.

Can I use the same crucible for different metals?

It’s best to stick to one type of metal per crucible. Mixing metals—like melting aluminum after copper—can cause contamination or chemical reactions. This might weaken the crucible or ruin your melt. Use separate crucibles if you work with different metals often.

How do I preheat a new graphite crucible?

Always preheat slowly before first use. Place it in a cold furnace or kiln. Raise the temperature gradually to about 600–800°C (1112–1472°F) over 30 to 60 minutes. Hold that temperature for 20 minutes. This removes moisture and prevents cracking during actual melting. Never put a cold crucible straight into a hot furnace.
