Cylindrical Graphite Heaters

Graphite heaters are heating components made using the resistive heating properties of graphite.  When the electric current flows through the heater, electrical energy is converted into heat via the resistance of graphite, and heat is then transmitted through thermal radiation. With precise control over resistance and current, the graphite heater can reliably reach the application's temperature requirements.

The advantages of Semicorex cylindrical graphite heaters

1.Excellent thermal conversion efficiency

Semicorex cylindrical graphite heaters deliver excellent thermal efficiency, which can rapidly heat to required temperatures without preheating. This excellent heating performance significantly shortens production cycles, improves production efficiency, as well as cuts down energy consumption and operating costs, providing a more stable and economical operating solution for high-temperature processes such as single-crystal manufacturing.

2.Uniform heat distribution

Semicorex cylindrical graphite heaters are precision-machined from high-purity, premium isostatic graphite. Formed under uniform pressure in all directions, isostatic graphite exhibits superior thermal conductivity, which can maintain uniform heat distribution during operation. This effectively avoiding crystal growth defects caused by localized overheating or temperature fluctuations in the monocrystalline silicon growth thermal field.

3.Reliable durability performance

Semicorex cylindrical graphite heaters feature exceptional high-temperature resistance and chemical corrosion resistance, demonstrating reliable durability in the harsh high-temperature and high-corrosive semiconductor processing conditions.

Applications across other industries

1. Semicorex graphite heaters are suitable for the applications in single crystal silicon growth furnaces in the PV industory, helping enhance the quality and efficiency of monocrystalline silicon growth

2. Semicorex graphite heaters can be applied to the uses for heating chemical reaction vessels, crude oil heating, and chemical synthesis in the chemical industry. They can fully match the temperature requirements of chemical production.

3. Semicorex graphite heaters are widely used in iron and steel production as well as non-ferrous metal smelting in the metallurgical industry. With their precise temperature control, they can greatly improve metal quality and boost overall productivity in processes such as metal melting and heat treatment.
