1. Overview of microwave tunnel kiln:

Hunan Province Zhongsheng Thermal Energy The microwave tunnel kiln developed by Science and Technology Co., Ltd. is mainly used for firing non-metallic materials in air atmosphere. Since the materials are loaded on the kiln car, the shapes can be diversified (powder, granular, sheet). Due to the use of this equipment microwave heating The product is heated evenly, the product quality is good, the process adjustment is flexible, and the production efficiency is high.

2. Structure composition of microwave tunnel kiln:

The microwave tunnel kiln is composed of feed microwave suppressor, microwave heating furnace body, slow cooling section furnace body, air cooling section furnace body, discharge microwave suppressor, return line, kiln car, moisture removal system, temperature measurement system, electric control system, microwave energy feeding system, water cooling system, air cooling system, etc.

3. Main technical parameters of microwave tunnel kiln:

1. Power supply: AC 380V ± 10V/50Hz;

2. Microwave output frequency: 2.45GHz ± 25MHz;

3. Installed microwave power: configured according to actual demand

4. Service temperature: not higher than 1400 ℃;

5. Temperature uniformity in high temperature zone: ± 6 ℃ (related to the cross-sectional area of the kiln);

6. Oil cylinder propulsion speed: stepless speed regulation;

7. Temperature control: automatic control/manual control;

8. Temperature measurement method: thermocouple:

9. Microwave leakage intensity: ＜ 2mW/cm2, the leakage is far lower than the national standard (GB10436-89) ＜ 5mW/cm2

4. Performance characteristics of microwave tunnel kiln:

1. Energy saving: more than 40% energy saving compared with traditional heating furnace;

2. Good product quality: based on the overall microwave heating mechanism, the product is evenly heated, and the product quality is good;

3. High production efficiency: the heating speed is 5-15 times faster than that of the traditional electric heating kiln;

4. Process flexibility: heating process curve can be selected and controlled automatically according to different materials;

5. Reliability: equipped with industrial water-cooled microwave source system, which can be used 24 hours without interruption Magnetron It can be replaced online, with its own microwave anti leakage alarm device and safety lock. When the microwave exceeds the standard, it will automatically or manually cut off the microwave power supply;

6. Small equipment floor area: 1/2 of that of ordinary electric kiln;

7. Environmental protection: no waste gas and waste water are discharged from the microwave kiln;

8. Automation: PLC+touch screen control mode, with automatic sintering, automatic data recording, access functions, multiple process temperature curves can be set, with automatic and manual dual operation control functions.

5. Scope of application of microwave tunnel kiln:

● Burning of magnetic materials: typical materials: nickel zinc ferrite;

● Burning of power battery materials: typical materials: lithium cobalate, lithium manganate, etc;

● Firing of electronic ceramic powder: typical material: BaTio3 SrTiO3 powder;

● Other materials: heating decomposition and oxidation of minerals, firing of daily ceramics, firing of sanitary porcelain, oxidizing roasting of petrochemical molecular sieve, impurity removal of synthetic diamond, metal oxide, etc.

Can be customized according to customer requirements
