Silicon Carbide Graphite Crucible With Pouring Nozzle
The Baidun Silicon Carbide Graphite Crucible with Pouring Nozzle is engineered for high-performance melting and handling of non-ferrous metals such as aluminum, copper, brass, bronze, zinc, and precious metals. Combining advanced materials with intelligent design, it delivers exceptional durability, thermal efficiency, and operational convenience for foundries, jewelers, and metal recyclers.
Silicon Carbide (SiC) Matrix:
Withstands temperatures up to 1600°C (2912°F).
Exceptional thermal shock resistance → survives rapid cycling (charging/pouring).
Resists oxidation, abrasion, and chemical erosion from molten metal/fluxes.
Graphite Reinforcement:
High thermal conductivity → faster melting and energy efficiency.
Non-wetting surface → minimal metal adhesion.
Monolithic Construction
The nozzle is integrally formed with the crucible body (not a separate attachment), ensuring:
Zero leak points between body and spout.
Superior structural integrity at high temperatures.
Eliminated risk of nozzle detachment during tilting/pouring.
Optimized Pouring Performance
Precision-engineered nozzle geometry enables:
Laminar metal flow (reduced turbulence and oxidation).
Accurate stream targeting for molds, ingots, or launder systems.
Controlled pour rates to minimize slag entrainment and splashing.
Product Chemical Composition
| Items | UNIT | Value |
| Carbon | % | 36~40 |
| Sic | % | 26~30 |
| SiO2 | % | 14~18 |
| Si | % | 2~5 |

The integrated pouring nozzle transforms a standard crucible into a unified pouring system, enhancing metallurgical quality through controlled metal transfer while reducing operator exposure to molten metal. Built to endure the thermal and mechanical stresses of industrial foundries, it delivers unmatched reliability for high-volume non-ferrous melting and casting.
Application:
Aluminum foundries (casting, recycling)
Copper & brass foundries
Precious metal melting (gold, silver)
Zinc alloy die-casting
Jewelry manufacturing
Metal recycling operations
Research & development labs
