Description

A kind of processing unit (plant) of steel-making oxygen lance

Technical field

This utility model belongs to the oxygen lance production technical field for being related to make steel, more particularly to a kind of steel-making oxygen lance Processing unit (plant).

Background technology

The oxygen lance majority of steel-making is the shape tube that two ends are thin, centre is thick, its existing processing method and technique at present More, such as extrinsion pressing, artificial hammering method etc., its processing technique is complex, as oxygen lance itself will to machining accuracy Ask low, relatively costly using existing manufacture method, be not suitable for industry application.

Utility model content

For solving problems of the prior art, this utility model design provides a kind of processing of steel-making oxygen lance Device, this processing unit (plant) simple structure, the oxygen lance that can process plurality of specifications using same covering device, and process velocity are fast, raw Produce low cost.

The technical solution of the utility model is as described below：

A kind of processing unit (plant) of steel-making oxygen lance, mainly by frame, crossbeam, mo(u)ld top half roller, mo(u)ld bottom half roller, driving means group Into mo(u)ld top half roller, mo(u)ld bottom half roller are respectively provided in frame, and one end of mo(u)ld top half roller and mo(u)ld bottom half roller is respectively equipped with driving means, and crossbeam is distinguished Connection left and right frame, is provided with several die cavities between mo(u)ld top half roller and mo(u)ld bottom half roller, each cavity dimension for ascending arrive again little Gradual change type structure.

In this utility model, mo(u)ld top half roller, mo(u)ld bottom half roller is driven to rotation by driving means, by pipe from die cavity Pass back through, be ascending little gradual change type structure to be arrived again by billet production into satisfactory two ends using each cavity dimension Carefully, middle thick shape tube.

Advantage of the present utility model and beneficial effect：

This utility model processing unit (plant) simple structure, the oxygen lance that can process plurality of specifications using same covering device have Process velocity is fast, efficiency high, low production cost the features such as.
