Online measurement and control method and device of filling ratio of flux-cored wire forming machine

Abstract

The invention provides an online measurement and control method and a device of filling ratio of a flux-cored wire forming machine. The flux-cored wire forming machine comprises a powder feeding hopper (12), a belt powder-feeding assembly (10) and steel strip rolling forming equipment. A powder flow measurement device is arranged between the powder feeding hopper (12) and the belt powder-feeding assembly (10), and the steel strip rolling forming equipment is provided with a steel strip speed detector (2). The method comprises the following steps: (A) measuring and calculating the powder weight (W1) through the belt powder-feeding assembly (10) in the same period of time and the weight (W2) through the steel strip (3) on the steel strip rolling forming equipment; and (B) calculating the filling ratio (Q) of the flux-cored wire according to a formula, and repeating step A until the filling ratio (Q) meets requirements. The method and the device have the advantages of simple method, reasonable design, strong practicability, high automation degree, high measurement and control precision, stable product quality and high production efficiency, and facilitating realization of accurate control of the flux-cored wire filling ratio and being capable of adapting to forming machines with high production efficiency.

Description
