I. Applicable Scope
A continuous high-temperature roller furnace is a high-efficiency kiln with high output and low energy consumption. Originally used in the construction ceramic, sanitary ware, and tableware industries, it has found applications in recent years in industries such as lithium battery materials, rare earth, magnetic material raw materials, electronic powders, and electrical porcelain pieces due to its many advantages and the development of roller materials, such as the emergence of recrystallized silicon carbide roller bars, which allow the furnace temperature to reach up to 1200°C. When high-output investment is required, roller kilns are the preferred choice. Roller kilns are suitable for large-scale production of products like advanced ceramics, electronic components, powder metallurgy, ultra-pure alumina powder, catalysts, magnetic materials, rare earth oxides, alumina, zirconia, cobaltic acid lithium, lithium manganate, lithium-ion ternary materials, cobalt oxide, mica powder, ultra-pure powders, magnetic materials, petroleum catalysts, glass crystallization, lithium battery materials, sodium battery materials, chemical powders, ceramic substrates, magnetic material raw materials, rare earths, electronic powders, electrical porcelain pieces, and more, which require large-scale drying and firing at temperatures below 1200°C.

Section 3: Kiln Features
1. Air environment, or nitrogen environment
2. The furnace chamber is made of a new material, pollution-free.
3. Utilize new refractory materials, which offer a 30% energy saving compared to traditional ones.
4. Filling Method: The material is loaded into a crucible, which is then placed on a roller bar for conveyance. The crucibles are arranged in double rows and double layers inside the kiln.
5. Kiln Atmosphere: Air. During the firing process, the material will generate a small amount of waste gases such as steam.
6. Atmosphere Control: Exhaust pipes are installed in the preheating and firing sections to accelerate the expulsion of various exhaust gases within the kiln.

V. Roller kiln control system
Temperature control is achieved through PID automatic control. Features include automatic temperature rise adjustment, PID self-tuning, and zero-crossing trigger. The actuator is a bidirectional可控硅, offering advantages such as no mechanical contacts, no noise, long lifespan, and no interference with the power grid. Operation
Concentrated, easy to observe.
The control panel features an intuitive visual structure, with each zone's temperature control system equipped with corresponding alarm devices, including over-temperature alarms for each zone. Additionally, each zone is fitted with an independent air switch for easy operation and maintenance.
Thermocouple temperature sensors use an insertable thermocouple and are equipped with a thermocouple insertion hole. When not in use, they should be tightly sealed with refractory fiber to prevent heat from escaping the furnace chamber. The control system ensures normal operation under rated conditions and can be...
24/7 continuous shipping. Production can be designed according to customer requirements.
Section 6: Roller Hearth Kiln Structure
6.1. The side wall of the furnace lining is constructed of wet-laid mullite lightweight bricks, with an insulating layer made of lightweight fiber materials.
6.2. The preheating degassing area is equipped with adjustable exhaust ports.
6.3. Side panels with detachable hangers (equipped with handles) for easy removal, with a protective cover on top, and an aesthetically pleasing appearance.
6.4. To reduce the export temperature of the product (approximately 90°C), a cooling water jacket is installed in the cooling zone, equipped with water temperature, over-pressure, under-pressure, or water shutdown alarm devices.
Section 7: Mechanical Motion Components
