Two-thread vertical thread feeding device

Abstract

The invention relates to a wire feeding method and a device thereof which are used for spheroidizing and inoculating treatment of molten iron and can input metal solid core wire or cored wire. Its main features are: it is composed of a core-spun wire guide device, a double-wire vertical wire feeding machine and a calculation input control unit. The guiding device is composed of a pair of concave wheels and a stopper. The wire feeder consists of two wire feed channels. Each wire feeding channel consists of two sets of toothed driving wheels and passive driving wheels. Each cored wire can be controlled individually. There is compressed air in the wire feeding channel. The calculation input control unit processes the input molten iron and core wire data and controls the operation of the equipment. Its advantages are: simple data input, single machine with two lines, small size and high degree of automation.

Description

technical field [0001] The invention relates to a wire feeding method and a device thereof which are used for spheroidizing and inoculating treatment of molten iron and can input metal solid core wire or cored wire. Background technique [0002] At present, the known cored wire is composed of a steel strip and powder wrapped in the steel strip. Therefore, the function of the wire feeding machine is to feed the cored wire into the molten iron treatment bag at a certain speed. The molten iron is treated at the bottom of the ladle for reaction. The traditional wire feeding system includes a "well"-shaped wire inlet consisting of multi-component, two-layer vertically placed non-powered rollers connected with rolling bearings and bases, a set of straightening mechanisms and a wire feeding machine. The wire feeding machine generally includes a wire feeding machine box body, and a wire feeding channel is arranged on the box body. The core wire outlet conduit and the core wire dri...

Problems solved by technology

In this way, it is necessary to manually estimate the length of the feeding wire, and the equipment is bulky, complicated in structure, and high in power consumption. When feeding the same wire with two channels or feeding two core wires with different components, the process will affect the feeding of the cored wire in the molten iron. When the insertion point has certain requirements, due to the long distance between the two feeding wire channels, especially when the horizontal cross-sectional area of ​​the molten iron or molten steel is not large enough, the cored wire has to go through a bend before entering the molten iron or molten steel, so that the metal The solid core wire or cored wire enters the molten iron after being straightened, transported, and then bent, so that the cored wire cannot be kept vertically entering the bottom of the ladle, so that a good treatment effect cannot be guaranteed
