BOGATSKIY V. Improve of design and ground of parameters powder additions screw batcher for out-oven steel treatment

Object of research. Process continuous dosage of a powder material with use batcher with moved powder by gravity direction vertical screw. The purpose of work. The development of the theoretical recommendations on perfection screw dosage devices of powder materials for out-oven steel treatment and substantiation their constructive and energy parameters. Methods of research. The theoretical researches were based on fundamental rules and methods of the mechanics of loose environments and theory of machines of continuous transport. The experimental researches. Test of a laboratory sample batcher with use of methods electrictensomeasuring in a complex with the analog-digital converter (ADC) and computer. The advanced constructive circuit batcher, providing high accuracy and uniformity dosage irrespective of mechanical properties of a material and design data bathcer is proved. The theory of mechanical interaction of a powder material with vertical screw is developed. The dependences for account energy parameters of process dosage with use batcher with vertical screw are received, which reinforced by experience. The dependences for a choice of design data batcher are received, at which the deduction of a material from the spontaneous expiration from the account bunker bather is provided at a stop screw, and also for a choice of the rational design data bather, at which least are provided specific energy of process dosage. The offered methods of account and dependence are used a bureau of the metallurgical equipment OAC "NKMZ" by development dosage devices of powder materials. Area of application - design and research dosage devices of powder materials.
