XICRU™ Crucibles for Zinc Oxide Distillation & Copper Alloy Processing

XICRU™ Crucibles for Zinc Oxide Distillation & Copper Alloy Processing

High-Performance Crucibles for zinc oxide distillation, copper, gold, silver, and rare metal smelting.

Our HT series isostatic pressed crucibles can withstand the intense temperature and chemical conditions of zinc oxide distillation and copper, gold, silver, and rare metal smelting. The crucibles work at 900°C to 1400°C for high-intensity procedures where traditional ones fail. Zinc vapor violently corrodes typical crucibles, but our HT Material endures this erosion. The silicon carbide-graphite matrix improves thermal conductivity and lowers vapor attack loss for such resistance. That boosts process stability and crucible life. Our high thermal conductivity speeds heat transmission for decreased energy use and assuring a homogeneous melt. HT Series (Gray): these crucibles receive an additional layer of anti-oxidation coating but do not undergo a second firing. Effectively, the gray crucibles have a double coating for enhanced oxidation resistance.

XICRU® Properties

  • Temperature range of 900-1400 °C
  • Maximum diameter 1525 mm x Height 1050 mm!
  • Our Series HT Crucibles work well in zinc oxide distillation, copper, gold, silver, and rare metal smelting.
  • low thermal expansion coefficients (4.1×10⁻⁶/°C).

Product Description

Sialon & Silicon Nitride Striko Sialon Westofen Dosing Tubes give the best price/performance rate when melting temperature of aluminum at 660.3 °C.

Sialon Dosing Tubes | Silicon Nitride Dosing Tubes | Sialon Westofen Dosing Tubes | Westofen Dosing Tubes | Striko Westofen Dosing TubesAs standard Aluminium Titanate dosing tubes have a relatively short service life (life span) and often clog during intensive use in Striko Westomat dosing furnaces, we have developed a low thermal conductivity Sialon dosing tube. These tubes come with a standard 12 months warranty against chemical attack.

The Westomat crucible dosing furnace is a clean, closed warming and dosing system for liquid aluminum. Depending on the system, the metal is always removed below the surface of the bath and is therefore automatically fed to the casting machine or casting mold free of contaminants.

Setting up and operating the system is easy with the silicon nitride Striko Sialon Westofen dosing tubes. And that with extremely low cleaning and maintenance costs. Its lifespan is proverbial: Our customers still use our riser tubes after 2-3 years in service. The Westomat furnace can also be heated with Sialon Immersion heaters. It can be integrated into any die casting system, but also in gravity casting. With variants from 450 kg to 3,100 kg capacity, the Westomat covers all cast part sizes.The hydrogen content of the molten aluminium can now be easily measured by using our new hydrogen content measurement device which has been optimized for ultrasonic degassing.
