In order to improve the production efficiency and safety of nitrocellulose, the continuous preparation process of nitrocellulose in Russian enterprises was analyzed. The new automatic production line of nitrocellulose represented by Kazan Explosive Ordnance Factory is introduced from the aspects of raw materials, process line transformation, improvement of supporting devices and safety analysis. The results show that the labor productivity of the production line is increased by 10% to 15% after the transformation, and the safety production is improved, which provides a reference for the upgrading and transformation of the automatic production line and packaging process line in the explosive industry in China.
