I. Applicable Scope

A continuous high-temperature roller hearth furnace is a highly efficient kiln type with high output and low energy consumption, originally used in the construction ceramic, sanitary ceramic, and tableware industries. Due to its numerous advantages and advancements in roller rod materials, such as the emergence of recrystallized silicon carbide roller rods, it has started to be employed in industries like lithium battery materials, rare earth, magnetic material raw materials, electronic powders, and electrical porcelain products in the past two years. With the introduction of recrystallized silicon carbide roller rods, the furnace temperature can reach up to 1200°C. When high output and investment are required, roller hearth furnaces are the preferred choice. Roller hearth furnaces are suitable for large-scale production of products such as advanced ceramic materials, electronic components, powder metallurgy, ultra-pure alumina powders, catalysts, magnetic materials, rare earth oxides, alumina, zirconia, catalysts, lithium cobaltate, 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 earths, electronic powders, electrical porcelain products, and others, for large-scale drying and firing at temperatures below 1200°C.

Section 5: Roller kiln control system

Temperature control utilizes PID automatic control. Features include automatic temperature rise adjustment, PID self-tuning, and zero-crossing triggering. 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, intuitive observation.

The control panel features an intuitive, visual layout. Each temperature control zone is equipped with a corresponding alarm device, including over-temperature alarms for each zone. Additionally, each zone has a separate air switch for easy operation and maintenance.

Thermocouple temperature sensors use an insertion type thermocouple and are equipped with a measuring 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 checked...

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