Types of Heating Elements for Melting
Silicon Carbide Glow Bars (Standard and Spiral Cut)
- Suitable for conventional roof-heated holding furnaces.
- Challenges include superheating melt surfaces, oxide formation, and hydrogen absorption.
- Adjustable power through transformers, prone to erratic failures.
Coiled Wire over Ceramic Tube Heaters (Manufactured by New Century Heaters)
- Suitable for roof-heated furnaces.
- Low resistance change, no tap switches needed.
- Not as easy to replace as glow-bars, but consistent performance.
Serpentine Stapled Wire Heaters
- Found in small holding furnaces.
- Long life, heavy-gauge wire requires a transformer.
- Limited information on replacement procedures.
Cal-Rod Heated Furnaces
Commonly used in small, low-powered holding furnaces.
Inexpensive and mass-produced, with limited power and higher failure rate.
Tolerant to spatter due to enclosed wire.
Considerations in Heating Element Selection
Choosing a heating element involves aligning furnace type, size, and power requirements with the element’s properties. Factors like heat generation, resistance change, ease of replacement, and cost are critical.
As industries strive for cleaner and more efficient melting processes, the choice of electric heating elements becomes critical. Each type comes with its own set of advantages and challenges, demanding a careful evaluation of specific needs. Staying abreast of heating technology developments ensures industries can meet customer demands and enhance operational efficiency in metal casting. Notably, New Century Heaters’ Coiled Wire over Ceramic Tube Heaters offer a reliable solution, aligning with the industry’s quest for excellence in melting processes.
