Product Description

Product Description

Clay Crucible for Non-Ferrous Metal & Foundry Applications

Our company's clay graphite crucible is a refractory container manufactured through scientific proportioning and high-temperature firing. It features excellent thermal conductivity and high-temperature resistance. During the high-temperature smelting process, it exhibits a low coefficient of thermal expansion and strong resistance to strain from rapid cooling and heating, making it an ideal tool for melting non-ferrous metals and their alloys such as copper, aluminum, and zinc.

Specification

Key Selling Points

High Thermal Conductivity: High graphite content ensures fast heat transfer, which significantly shortens melting time and saves energy.

Good Thermal Stability:Suitable for harsh working environments involving rapid cooling and heating; not prone to cracking, offering a long service life.

Strong Corrosion Resistance: Possesses strong resistance to corrosion from acidic and alkaline slags and molten metals.

High Mechanical Strength: The dense structure maintains excellent performance even under high pressure and high temperatures.

Good Oxidation Resistance:The surface is protected with a special glaze, effectively extending the service life of the crucible.

Important Notice

When using a clay crucible, always handle it gently, as it is brittle at room temperature. Before use, it must be completely dry, and you must ensure a slow, even rise in temperature, avoiding direct flame impingement to prevent cracking from thermal stress.

 When melting, control the amount of material loaded and avoid large pieces from striking the inner wall. After each use, carefully clean out the slag and check for cracks to ensure its safety and longevity.
