Industry Application: Lithium Battery Industry

Product Model Used: AI-826

Process Overview:
The roller hearth furnace controls the kiln temperature by adjusting the electric heater through a power controller. During the sintering process, raw materials undergo high temperatures and high pressures to form lithium-ion battery electrode materials with specific mechanical strength and electrochemical properties. The roller hearth furnace requires a precise temperature control system and temperature measurement components to ensure accurate control of the sintering process.

On-Site Application Details:
Due to the complexity of heat transfer methods and principles within the roller hearth furnace, as well as the influence of various factors such as heating power, inlet air velocity, and temperature, customers require temperature control accuracy within ±1℃. The Yudian AI-826 temperature controller offers precise control with ramp-up and ramp-down temperature modes, ensuring the accuracy and uniformity of the furnace's internal temperature. This achieves stable temperature control in lithium battery roller hearth furnaces, ensuring material consistency.

Value Delivered to Customers:
The lithium battery industry consumes significant amounts of electricity, and simultaneous full-power input/output of large quantities of temperature controllers can easily cause the main circuit breaker to trip due to insufficient power supply. The idle power consumption of Yudian temperature controllers is as low as 0.2W, reducing energy consumption. Stable control performance helps maintain product yield at over 99%.

Customer Feedback:
Yudian’s instruments offer modular customization capabilities, allowing us to develop functions tailored to different process requirements. Previously, we used Omron temperature controllers from Japan, which lacked technical support and after-sales service. In contrast, Yudian staff provide on-site debugging services and assist us in resolving all issues.
