S-shaped variable-speed wire feeding spheroidizing method

Abstract

The invention provides an S-shaped variable-speed wire feeding spheroidizing method, and belongs to the technical field of cored wire machining, the S-shaped variable-speed wire feeding spheroidizing method comprises the following steps: S1, a wire feeder drives a cored wire to move to the liquid level of molten iron in a ladle; s2, the wire feeder drives the cored wire to move from the liquid level of the molten iron to the inner bottom of the ladle; and S3, the wire feeding machine drives the cored wire to retreat to a ladle opening of the ladle, the wire feeding machine drives the cored wire to be rapidly fed to the liquid level of the molten iron firstly, then the cored wire slowly moves to the inner bottom of the ladle from the liquid level of the molten iron, finally, the cored wire rapidly moves to the ladle opening of the ladle from the inner bottom of the ladle, and wire feeding is conducted through the S-shaped wire feeding method. The wire feeding time is appropriate, the beat is not affected, the core material of the cored wire is not oxidized when the cored wire is grilled at a high temperature, and finally the spheroidizing effect of the cored wire is stable.

Description

technical field [0001] The invention relates to the technical field of cored wire processing, in particular to an S-type variable speed feeding wire ballizing method. Background technique [0002] The existing cored wire is generally sent to the bottom of the ladle at a certain speed by a wire feeding machine, and the eruption begins about 10 cm away from the bottom of the ladle, so that the cored wire is spheroidized At present, when the cored wire is spheroidized, when the wire feeding speed is too fast, the cored wire will directly poke on the bottom of the molten iron ladle, and then cause the cored wire to break and float on the molten iron surface to explode, and the spheroidization effect Unstable; when the wire feeding speed is moderate, the following two problems will occur: ①The feeding time of the wire is too long, which affects the beat; Oxidation of the core material of the cored wire will lead to a relatively large amount of cored wire added and unstable spher...
