I. Applicable Range

A continuous high-temperature roller hearth furnace is a high-efficiency kiln type with high productivity and low energy consumption. Originally used in the building ceramics, sanitary ceramics, and tableware industries, it has gained popularity due to its numerous advantages and advancements in roller rod materials, such as the emergence of recrystallized silicon carbide roller rods. In the past two years, it has begun to be used in industries like lithium battery materials, rare earth, magnetic material raw materials, electronic powders, and electrical porcelain components. The appearance of recrystallized silicon carbide roller rods enables furnace temperatures to reach 1200°C. When high productivity investments are required, roller hearth furnaces are the preferred choice. Roller hearth kilns are suitable for large-scale production and are used for the large-scale drying and firing of products such as advanced ceramic materials, 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 powder, ceramic substrates, magnetic material raw materials, rare earth, electronic powders, electrical porcelain components, and more, all operating below 1200°C.

Section 5: Roller Kiln Control System

Temperature control utilizes PID automatic control. Features include automatic heating adjustment, PID self-tuning, and zero-crossing triggering. The actuator is a bi-directional silicon-controlled rectifier, offering advantages such as no mechanical contacts, no noise, long lifespan, and no interference with the power grid. Operation

The control panel features an intuitive visual structure, with each zone's temperature control system equipped with corresponding alarm devices, including over-temperature alarm devices for each zone. Additionally, each zone is fitted with an independent air switch for convenient operation and maintenance.

Thermocouple temperature sensors utilize plug-in type thermocouples 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 operated every

24/7 continuous shipping. Production can be designed according to customer requirements.
