Heavy-Duty Crucibles Tailored for Demanding Applications

At SHJ-CARBON, we specialize in large graphite crucibles engineered to meet the extreme conditions of high-temperature industrial operations. With customizable height, bottom diameter, top diameter, and wall thickness, our crucibles are ideal for heavy-load applications such as metal melting, alloy refining, and continuous casting.

Available in barrel, cylindrical, and conical shapes, these crucibles are designed for compatibility with a wide range of furnaces and workflows. Despite their size, each crucible remains lightweight and easy to install, offering both handling convenience and structural strength.

Our large graphite crucibles are capable of withstanding temperatures up to 1800°C in oxidizing atmospheres and up to 3000°C in vacuum or inert conditions. Even under prolonged exposure to extreme heat, they maintain structural integrity and resist cracking, warping, or erosion.

These crucibles are suitable for melting aluminum, copper, gold, silver, brass, and other non-ferrous metals. They are also used in glass and ceramic processing, where thermal uniformity is essential for product quality.

At SHJ-CARBON, we specialize in large graphite crucibles built for scale, precision, and long-term performance. Every crucible is fully customizable-from raw material grade to geometry, wall thickness, machined features, and surface treatments-to meet the specific demands of your melting process, furnace design, and metal type.

Whether you're expanding industrial capacity or fine-tuning alloy composition, our OEM customization service ensures that each large crucible integrates seamlessly into your operation. We don't just offer products-we deliver engineered solutions that support clean melts, thermal stability, and repeatable quality across every cycle. Reach out to our team today to explore how our custom large graphite crucibles can elevate your high-temperature process with precision and confidence.
