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 ceramics, sanitary ceramics, and tableware industries. Due to its numerous advantages and the development of 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. 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 mass 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 cobalt oxide, lithium manganate, lithium-ion ternary materials, cobalt oxide, pearlescent powders, 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 components, and others, for large-scale drying and firing operations, all working at temperatures below 1200°C.

Five: 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 silicon-controlled rectifier, which boasts advantages such as no mechanical contacts, no noise, long lifespan, and no interference with the power grid, making operation

Concentrated, intuitive observation.

The control panel features an intuitive visual structure. Each zone's temperature control system is 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 measurement utilizes an insertion-type thermocouple, equipped with a thermocouple insertion hole. When not in use, it should be 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.
