High temperature resistant yarn feeder yarn guiding tube

Abstract

The invention discloses a high temperature resistant yarn feeder yarn guiding tube. The high temperature resistant yarn feeder yarn guiding tube comprises a shell, two ends of the shell are respectively provided with a flange, a V-shaped pawl nail is welded to the outer wall of the shell, a pawl nail welded portion is knotted with a fireproof protection layer, the inner wall of the shell is fixedly provided with rollers, and the rollers are arranged in two rows, so the burning loss of the yarn guiding tube is effectively controlled, the service life of the yarn guiding tube is prolonged, the replacement frequency is reduced, and the cost is saved; and the rollers at the inner wall of the yarn guiding tube allow core-spun yarns to be smoothly conveyed to molten steel, so the yarn guiding tube has a fast guiding effect on hard core-spun yarns especially to make the core-spun yarns smoothly enter the molten steel.

Description

Technical field [0001] The invention relates to a conduit of a high temperature resistant wire feeding machine. Background technique [0002] The wire feeding machine is mainly used to inject the alloy core wire into the depth of the molten steel at a reasonable speed and accurate amount to make it evenly diffuse to achieve deoxidation, desulfurization, change the shape of inclusions, improve the fine-tuned composition of the steel, and improve the pouring performance. At present, the wire device of the wire outlet of the wire feeding machine is a curved catheter, which is used to guide the horizontally conveyed cored wire downwards into the ladle. The cored wire will bear greater frictional resistance when passing through the curved catheter. Clogging often occurs, causing the feeding line to be interrupted and affecting production efficiency. In addition, during the feeding process, due to the relatively large splash of molten steel, the wire tube is burnt and deformed, which n...

AI Technical Summary

Problems solved by technology

At present, the wire device at the wire outlet of the wire feeding machine is a curved conduit, which is used to guide the horizontally conveyed cored wire downward into the ladle. When the cored wire passes through the curved conduit, it will bear greater frictional resistance. Blockages often occur, causing interruption of the feeding line and affecting production efficiency. In addition, during the process of feeding the line, due to the relatively large splash of molten steel, the wire tube is burned and deformed, which not only directly affects the wire feeding effect, but also leads to wire tube damage. Reduced service life increases costs
