Introduction
Roller Hearth Kiln (RHK) is a specialized furnace widely used in the production of materials for lithium-ion batteries, particularly in the processing of cathode and anode materials. The roller hearth design allows for continuous, high-volume production with excellent temperature uniformity, which is critical for achieving the desired material properties. The kiln's structure typically includes rollers made from silicon carbide, a material known for its durability and ability to withstand high temperatures.
Beyond battery materials, Roller Hearth Kilns are also extensively utilized in other industries. In the ceramic industry, they play a crucial role in the sintering of ceramic powders, ensuring consistent quality and performance of ceramic tiles, substrates, and other components. Additionally, these kilns are employed in the chemical powder sector for the processing of various fine powders, such as those used in catalysts and specialty chemicals. The hearth kiln configuration ensures that all materials are evenly exposed to the controlled heating environment, making it an ideal solution for producing high-performance components across multiple applications.
