Non-metallic Material Microwave Roasting Kiln, Microwave Heating Energy Saving Contributes to Carbon Neutrality

I. Heating Applications of Microwave in Non-metallic Materials

Non-metallic material microwave roasting utilizes microwave bell furnaces, shuttle kilns, or pusher kilns with specialized microwave sintering processes to perform vacuum sintering or atmosphere-protected sintering of non-metallic materials. Compared with conventional calcination processes, it can lower the roasting temperature, achieve rapid and uniform sintering, produce fine grains, high density, no deformation, and no cracking; significantly shorten the sintering cycle; and markedly save electricity. Non-metallic materials for microwave roasting include: special ceramic powders, battery material powders, non-metallic powders, powder metallurgy, oxides, tantalum hydride, zirconia, alumina, silica, aluminum nitride, silicon nitride, quartz sand, talcum powder, kaolin, diatomite, wollastonite powder, mica flakes, silica fume, graphite, carbon products, diatomite, titanium nitride powder, diamond, titanium carbide, lithium aluminate, ceramic-based, metal-based, carbon-based composite materials, etc.

Therefore, microwave heating replaces the original coal, electric, and gas heating modes, saving over 30% energy; for every kilowatt-hour of electricity saved, it reduces standard coal by 0.4 kg and carbon dioxide emissions by 0.997 kg. By enhancing energy efficiency to contribute to carbon neutrality, the era of microwave heating has arrived, and microwave heating is becoming the new generation heating technology of the 21st century!

II. Application Characteristics of Microwave High-Temperature Industrial Equipment:

Principle of non-metallic material microwave roasting equipment: Microwave is an electromagnetic wave. Dielectric materials composed of polar and non-polar molecules, under the influence of a high-frequency microwave electromagnetic field, cause polar molecules to shift from their original random distribution to align according to the electric field's polarity. The polar molecules in the medium transition from their original thermal motion state to follow the alternating microwave electromagnetic field, generating intense friction and producing heat. Microwave energy is converted into thermal energy within the medium, resulting in a macroscopic temperature rise—this is the basic principle of microwave heating. Microwave heating is a penetrating internal heating method where electromagnetic energy directly acts on the medium's molecules to convert into heat, and its transmissive properties allow both the internal and external parts of the material to heat simultaneously without the need for heat conduction. The lack of internal heat dissipation conditions creates a temperature gradient distribution with higher internal than external temperatures, forming a pressure differential that drives internal heat or moisture to permeate to the surface. In contrast, conventional heating methods use radiation, convection, and other heat conduction processes from the outside in, from surface to interior, resulting in high energy consumption, low energy efficiency, long heating times, and a tendency for coking, requiring regular furnace cleaning, shutdown maintenance, and frequent replacement of components that are not temperature or corrosion resistant.

Advantages of microwave industrial kilns: Energy saving (higher conversion efficiency to thermal energy, saving over 30% energy compared to traditional heating methods), environmental protection (no external emissions, effectively reducing harmful substance production), cleanliness (materials absorb microwave heat themselves, no contact pollution, improving product quality and yield), high energy efficiency (fast heating speed, high energy utilization rate); and ZhongSheng's microwave industrial equipment can operate at temperatures up to 1600°C, with kiln temperature stability of ±5°C, and can be integrated with automation and intelligent operations to improve the production environment.

III. ZhongSheng Microwave Kiln Equipment Industry Advantages:

Hunan ZhongSheng Thermal Energy was established in 2011 with a registered capital of 12 million yuan. It is a company long engaged in the research, development, application, and integration of design, manufacturing, and sales of industrial microwave thermal energy technology. It primarily produces microwave experimental furnaces suitable for enterprises and research institutions, as well as custom industrial microwave equipment. In the field of microwave applications, it holds 12 invention patents and 57 utility model patent certificates, with microwave heating kiln technology already included in the NDRC's fifth batch of key energy-saving technology promotion catalogs. Compared to low-power household microwave ovens, ZhongSheng Thermal Energy's industrial-grade microwave equipment is designed for continuous operation in production, ensuring stable production and meeting equipment usability requirements. It is specially configured with 1.5KW industrial-grade microwave sources, with continuously adjustable power to ensure uniform, adjustable, and controllable furnace chamber temperatures. It guarantees 24-hour uninterrupted use and employs special crack antenna energy feed devices to ensure uniform microwave fields and prevent microwave reflection from damaging the magnetron, allowing the magnetron to operate 24 hours without shutdown. It also enables online replacement of wearing parts without affecting normal production operations. Special microwave leakage prevention devices are used: microwave leakage does not exceed 1mW/cm² (standard microwave leakage is not more than 5mW/cm²), enhancing production safety, while other manufacturers generally only meet industry requirements. ZhongSheng's series of microwave drying lines, microwave experimental furnaces, microwave high-temperature bell kilns, microwave high-temperature pusher kilns, microwave high-temperature roller kilns, microwave pyrolysis kilns, etc., all have successful application cases.
