Specification of crucible 20kg

20kg Crucible– Technical Requirements

Material and Construction

This 20kg crucible is made from high-purity graphite. The product supplies strong resistance to thermal shock and chemical deterioration. Its thick framework guarantees lengthy life span also under duplicated home heating cycles. The crucible walls are evenly thick to support also warmth circulation and reduce the risk of splitting.

Capability and Measurements

The crucible stands up to 20 kilograms of liquified metal, generally aluminum or copper alloys. External measurements are approximately 280mm in height and 220mm in size. Internal usable quantity is created to enable risk-free filling without overflow throughout melting or pouring. A tapered form helps with easy removal of solidified ingots.

Temperature Efficiency

It runs securely at constant temperature levels approximately 1,200 ° C(2,192 ° F). Short-term direct exposure can reach 1,500 ° C (2,732 ° F) without structural failing. This makes it ideal for shop job, lab melting, and small steel spreading procedures.

Handling and Compatibility

The crucible fits standard lifting tongs and heater arrangements. It functions well with gas-fired, electric resistance, and induction furnaces. Users should preheat the crucible slowly prior to initial usage to get rid of dampness and avoid thermal anxiety. Always handle with completely dry tools to stay clear of contamination or damages.

Quality Assurance

Every device goes through stringent quality checks. We examine for surface area splits, density uniformity, and dimensional accuracy. Each batch features a certificate confirming product pureness and efficiency requirements. Packaging consists of protective extra padding to avoid breaking throughout shipping.

Upkeep Tips

Clean the crucible after each use by eliminating residual slag. Stay clear of sudden cooling– let it amazing naturally inside the heating system or on a heat-resistant surface. Do not relieve in water. Store in a completely dry area far from moisture to maintain integrity for future melts.

Applications of crucible 20kg

Applications of the 20kg Crucible

Steel Melting and Casting

The 20kg crucible is built for melting steels like light weight aluminum, copper, brass, and bronze. It handles heats without splitting or flawing. Shops and small workshops utilize it day-to-day to melt scrap steel or ingots. Once melted, the steel pours smoothly right into mold and mildews for casting components, jewelry, or art items.

Heat Treatment and Alloying

This crucible functions well in warmth therapy procedures. Customers include alloying components straight into the molten steel inside the crucible. The product withstands chemical reactions, so the last alloy stays pure. It’s common in laboratories and manufacturing stores where constant metal composition matters.

Recycling Procedures

Recycling centers rely upon the 20kg crucible to reclaim useful steel from waste. Old car parts, electrical wiring, or electronic scrap go in. The crucible holds up under duplicated heating and cooling down cycles. Operators obtain tidy, reusable metal with less loss and lower power usage.

Education and learning and Training

Technical colleges and training programs utilize this size crucible for hands-on lessons. It’s safe sufficient for pupils yet solid sufficient for real-world method. Students discover melting, putting, and security actions using tools they’ll see on real job websites.

Small-Scale Production

Artisans and small producers choose the 20kg version because it fits basic heaters. It provides control over batch size without squandering product. Whether making personalized equipment or attractive things, they depend on also warming and trustworthy performance every single time.

The crucible’s thick wall surfaces and top notch refractory product make it last longer than less costly choices. It deals with gas, electric, and induction heaters. Customers appreciate just how very easy it is to handle, clean, and store in between usages.

5 FAQs of crucible 20kg

Frequently Asked Questions About the 20kg Crucible

What is a 20kg crucible used for?

A 20kg crucible holds and melts metals like aluminum, copper, or gold. People use it in foundries, jewelry workshops, and small metal casting operations. It can safely handle high temperatures during melting.

What material is the crucible made of?

Most 20kg crucibles are made from high-quality graphite or clay-graphite mixtures. These materials resist heat well and last long under repeated heating and cooling. They also help keep the melt clean and reduce metal loss.

How much metal can it actually hold?

The “20kg” label means it can hold up to 20 kilograms of molten metal. But you should never fill it to the very top. Leave some space—usually about 10%—to prevent spills when moving or pouring the metal.

Can I use it with any furnace?

You must match the crucible to your furnace type. Check your furnace’s size and heating method first. A 20kg crucible works best in medium to large induction or gas-fired furnaces that support its weight and shape.

How do I take care of my crucible?

Always preheat the crucible slowly before full use. This prevents cracks from sudden temperature changes. After each use, let it cool down naturally. Avoid dropping it or hitting it hard. Store it in a dry place to stop moisture damage. Clean out leftover slag gently—never use sharp tools that could scratch or weaken the walls. Proper care helps it last many melting cycles.
