STUDY ON A NEW KIND OF POWDER-FEEDING APPARATUS OF FLUX-CORED WIRE PRODUCTION LINE

摘要

A set of electromagnetic vibration powder-feeding apparatus of the flux-cored wire production line and its single-chip controlling system have been designed in this paper. The parameters of the electromagnatic vibration powder-feeding apparatus have been tested, the functional relation between powder-feeding velocity V_L and current I has been made out so that the controlling system can not only automatically make out the quantity of the powder according to the width of the steel-belt, powder density , production speed and filling ratio, but also adjust the powder-feeding speed according to the real production speed, keeping a stable filling-ratio.
