The NBD-LT series high-temperature furnace adopts international advanced manufacturing technology as a whole, and is designed from an aesthetic and artistic perspective based on human safety. The furnace liner is made of high-purity aluminum oxide lightweight fiber material, and the control interface is equipped with an intelligent touch screen for foolproof operation. The control mathematical model adopts advanced PID self-learning fuzzy control to maintain temperature control accuracy at ± 1℃. After long-term and multiple sample verifications, it can be applied to the calcination of almost all types of materials. Due to the batch standardization of its production process, the consistency of sample quality can be ensured
