Device for metallurgically adding alloy

Abstract

The invention discloses a device for metallurgically adding an alloy. A ladle cover of a conventional alloy liquid container is provided with a guide support; a guide frame is arranged in the guide support; a belt motor reducing gear and counter weight iron are arranged in the guide frame; a steel wire rope is sheathed onto guide wheel assemblies at the top part of the guide support; one end of the steel wire rope is connected with the guide frame; the other end of the steel wire rope is connected with an elevator arranged at one side of the guide support; one end of a material frame rod is fixedly connected with a material frame; and the other end of the material frame rod passes through a hole on the ladle cover and is mutually connected with the output shaft of the belt motor reducing gear through a shaft sleeve. The device for metallurgically adding the alloy has the advantages as follows: the alloy needs to be added is directly pressed into alloy liquid, is directly melted in thealloy liquid and cannot be contacted with the air, and thus, oxidation or burning loss cannot occur; the contact speed and the reaction speed of the alloy needs to be added and the alloy liquid can be controlled, thereby, the absorption evenness and the and the component evenness of the alloy in molten steel are enhanced. The addition process is simplified, the labor strength is reduced, and the application range is wide.

Description

technical field [0001] The invention relates to a device for metallurgically adding alloys. Background technique [0002] In metallurgical smelting, the method of adding other alloys is usually used for quenching and tempering and purification treatment to improve its performance. The method of adding alloys generally adopts wire feeding method, direct addition method and flushing method. The direct addition method and the flushing method are to directly add the alloy to be added into the furnace for melting or add it to the ladle in advance or add it with the alloy liquid. The alloy with a large specificity is easy to precipitate to the bottom of the ladle or the bottom of the furnace, resulting in long melting time. The composition is difficult to homogenize, and alloys with small specific gravity are easy to float on the melt, causing oxidation, low absorption rate of effective elements, and difficult to control quenching and tempering treatment. The wire feeding method ...

Problems solved by technology

The direct addition method and the flushing method are to directly add the alloy to be added into the furnace for melting or add it to the ladle in advance or add it with the alloy liquid. The alloy with a large specificity is easy to precipitate to the bottom of the ladle or the bottom of the furnace, resulting in long melting time. The composition is difficult to homogenize, and alloys with small specific gravity are easy to float on the melt, causing oxidation, low absorption rate of effective elements, and difficult to control quenching and tempering treatment

The wire feeding method is to crush the alloy to be added into powder first, then roll it into a round tubular wire on the cored wire unit, and then add it into the alloy liquid with a wire feeder. This method requires a special cored wire The unit and wire feeding machine sell the steel strip as a product to the user during rolling, which increases the cost more. Moreover, the alloy is broken into powder and is easy to oxidize. It is difficult to guarantee the quality of the wire product, so it is difficult to control the effect of quenching and tempering treatment.
