Description

Conduit structure of wire feeding machine Technical Field The utility model belongs to the technical field of wire feeders, and particularly relates to a conduit structure of a wire feeder. Background In the molten steel smelting technology, the calcium treatment has extremely important effect and significance in molten steel smelting. Through calcium treatment, the inclusion in molten steel can be subjected to accurate denaturation treatment, so that the morphology and distribution of the inclusion are effectively improved, the adverse effect of high-melting-point inclusion on the production flow is reduced, such as water gap blockage prevention, continuous casting forward running improvement and the like. Meanwhile, the purity of molten steel can be further improved by calcium treatment, the oxygen content is reduced, and the mechanical property and the processing property of steel are improved. The wire feeder which is one of important equipment for calcium treatment is widely applied in steelworks and has high use efficiency. The main part of the wire feeder consists of a guide wheel and a guide pipe, and the calcium wire is conveyed to the guide pipe by the guide wheel and then enters molten steel at an almost vertical angle by changing the direction in the guide pipe. The disadvantage of the prior art is 1. The calcium wire is sinuously coiled. After the calcium wire is sent out and passes through the guide pipe, bending stress still exists and can not be changed into a straight state, so that the force for inserting molten steel is not large enough, the molten steel can not be inserted deep enough, the center of the molten steel can be possibly deviated, and the Ca treatment effect and the yield of the molten steel are seriously affected. If the Ca yield is to be increased, the guide tube can be brought as close to the molten steel as possible, thereby reducing the influence of the insufficient straightness of the calcium line. 2. Because of the high temperature of molten steel and the explosion of molten steel during wire feeding, the guide pipe close to the molten steel is continuously burnt, and the state of the defect 1 is repeated, so that workers are required to weld the guide pipe for a small period. This approach is labor intensive and inefficient and can also affect production if not maintained in time. The technology belongs to the metallurgical field, and particularly discloses a immersed wire feeding sleeve, a wire feeding machine and a wire feeding method, which aims to solve the problems of poor yield stability and low wire feeding efficiency of wires made of valuable elements which are easy to burn by adopting the existing wire feeding guide tube. The immersed wire feeding sleeve comprises an inner sleeve, an outer sleeve sleeved on the inner sleeve and an outer sleeve driving device, wherein a scraping part is arranged on the outer surface of the inner sleeve and is in sliding connection with the outer sleeve, and the outer sleeve driving device is connected with the outer sleeve and can drive the outer sleeve to move along the axial direction of the inner sleeve. The wire feeding machine comprises the immersed wire feeding sleeve. The wire feeding method is a wire feeding method by using the wire feeder. The immersed wire feeding sleeve is used for feeding wires, so that the wire feeding requirements of normal wires can be met, the wire feeding requirements of special wires made of noble elements which are easy to burn can be met, and the wire feeding yield of the special wires can be remarkably improved. The technology does not relate to the technical problems and technical proposal of the application.
