Crucible Accessories

Product catalog summary

Overview
Morganite produces a wide range of crucible accessories and foundry products aimed at enhancing crucible performance. These include stands, muffle rings, covers, spouts, lifters, pyrometer sheaths, launders, and ladle bowls.

Product Range

Crucible Accessories: Stands, muffle rings, covers, spouts, and lifters.
Foundry Products: Pyrometer sheaths, launders, ladle bowls, degassing tubes, etc.

Applications
Excel E and Iso-Alustar crucibles are used for aluminum and zinc, while Excel, Hi-Melt, and Ultramelt are for copper alloys and precious metals. Salamander accessories provide spout extensions and covers.

Performance Characteristics
Crucible accessories are optimized for thermal conductivity, shock resistance, oxidation resistance, and wear resistance, adhering to ISO9000:2000 standards.

Safety
Use proper safety clothing and ensure tools are dry before contact with molten metal. Prepare to catch discharged metal.

Specific Products

Excel/Excel E Stands: Available in various sizes with specific dimensions.
Muffle Rings: Offered in different sizes for various applications.
Salamander Covers: Standard and tilter covers in multiple sizes.
Spout Extensions: Designed for specific crucible types with detailed dimensions.

Crucible Types

Ultramelt: High-quality silicon carbide crucibles for aggressive conditions, offering superior erosion and thermal shock resistance.
Excel and Himelt: Carbon-bonded silicon carbide crucibles for non-ferrous melting, known for fast melting and oxidation resistance.
Excel E: Designed for aluminum melting, offering energy efficiency and high thermal conductivity.
Indux: Ceramic bonded clay graphite crucibles for induction melting, providing controlled electrical resistivity and good thermal conductivity.

Preheating and Charging
Crucibles should be pre-heated to a bright red color to condition the glaze. Charge light scrap first, followed by heavier materials, and add flux only once the metal is molten.

Specifications and Quality Standards
Crucibles are made from premium materials and meet ISO9000:2000 standards, ensuring high oxidation resistance, mechanical durability, and consistent performance.

Charging Procedures
Charge light scrap first to cushion heavier materials. Use tongs for ingots and place large pieces vertically. Add flux only when the metal is molten.

Preheating and First Use

Push-Up/Drop Coil Furnaces: Preheat based on furnace frequency and metal resistivity. For 3 kHz, start at 20% power, increasing to 50% after 30 minutes. For 1 kHz, preheat with a charge if necessary.
Tilting Furnaces: Preheat empty to avoid thermal shock, using a maximum of 100Kw or 50% power.
Electric Resistance and Gas Fired Furnaces: Preheat empty, gradually increasing to 950°C to develop the anti-oxidant glaze.
Fuel-Fired Furnaces: Preheat slowly to 600°C, then increase to a uniform bright red condition.
Induction Furnaces: Preheat empty, starting at 20% power and increasing to 50% after 30 minutes.

Crucible Types and Applications

ISO-ALUSTAR: For aluminium and zinc, offering excellent resistance to chemical agents and oxidation.
SALAMANDER SUPER: Suitable for fuel-fired and induction furnaces, used for melting precious metals and some ferrous alloys.

Performance Characteristics
Crucibles offer clean melting, good thermal conductivity, resistance to chemical corrosion, and high refractoriness, available in various shapes and sizes.

Crucible Care and Maintenance
Store crucibles in a dry, warm place, avoid nesting, and check for damage before use. Use the correct stand and handle properly to prevent damage. Clean crucibles daily while hot and allow space for expansion.
