The integration of China's oven industry and new energy industry has formed a deep collaborative system with material preparation as the core, electrification as the path, and intelligence as the engine. In the field of lithium batteries, the sintering of lithium iron phosphate cathode materials widely adopts multi temperature zone roller kilns and box atmosphere furnaces to achieve precise control of oxygen content<50ppm at 600-900 ℃. In 2023, the market size of lithium battery material baking ovens will reach 9.505 billion yuan, accounting for 52% of the total industrial kiln scale and becoming the largest growth pole; In the field of photovoltaics, tunnel type sintering furnaces use multi-stage temperature control to form ohmic contact between silver paste and silicon wafers, improving battery conversion efficiency by over 0.2%; In the field of hydrogen energy, hydrogen furnaces (working temperature 1200-2300 ℃) are used for sintering fuel cell electrodes and heat treatment of hydrogen storage materials, achieving bright annealing and oxygen free purification. Electric heating replacing traditional fuels has become a rigid trend, and standards such as GB/T 44761-2024 are promoting the improvement of heat treatment energy efficiency, leading to a continuous increase in the penetration rate of electric kilns. Intelligent upgrading is accelerated: 5G private network realizes remote monitoring of oven drying and millisecond level abnormal early warning (such as 5G intelligent factory of Hebei Coking Plant), industrial Internet platform combines AI algorithm to dynamically optimize temperature control curve, reducing energy consumption per ton of products by 12% – 30%; Explosion proof hot air circulation ovens are widely used in small and medium-sized enterprises of new energy in Jiangsu and Anhui provinces, meeting the Ex d IIC safety requirements for drying flammable electrolytes. The industry is transforming from an 'equipment supplier' to a 'core process node service provider for new energy production lines', building an integrated solution of 'material characteristics process parameters energy efficiency closed-loop'.
