Beschreibung
Zusammenfassung:	The invention provides a cartridge case lengthening water-free cleaning and processing process. The process comprises the following steps of discharging, cupping, cup annealing, cup rolling with powder, primary lengthening, primary guide annealing, primary guide powder rolling, secondary lengthening, tertiary lengthening, fourth lengthening and cutting. According to the process, soapy water cooling liquid is replaced, powder rolling treatment is carried out on a cartridge case cup and a lengthened product, a polytetrafluoroethylene-based tensile lubricating film 5 and a polytetrafluoroethylene-based tensile lubricating film 6 are formed on the surface after processing is carried out, five surface cleaning procedures are omitted, the water consumption is avoided, only two times of powder rolling treatment are needed, and all lengthening processing can be completed. The lengthened product is qualified in appearance and size, a large quantity of water and water treatment expense is saved,and environmental friend
