Technical Field

The utility model relates to a cast steel oxygen lance technical field specifically is a slag scraper of oxygen lance for cast steel converter.

Background

The oxygen lance is one of the main process equipments in oxygen converter steelmaking. The surface of the oxygen lance can be adhered with molten metal in the using process and solidified into slag after cooling, under the condition, the steel slag on the surface of the oxygen lance needs to be removed in time, the normal use of the oxygen lance is ensured, and if the oxygen lance is not treated in time, more and more steel slag are adhered to the outer surface of the oxygen lance, so that the consumption cost of the oxygen lance is higher.

In order to solve the problems, an oxygen lance slag scraper for a cast steel converter is provided.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a slag scraper for cast steel converter oxygen rifle, in order to solve above-mentioned technical problem, the utility model provides a following technical scheme:

the utility model relates to a sediment ware is scraped to cast steel converter oxygen rifle, including two structure identical and the symmetry setting scrape the sediment subassembly, scrape the sediment subassembly and include drive division, guide part and scrape sediment portion, it includes C type knife rest to scrape sediment portion, the inner arc department of C type knife rest is fixed with scrapes the sediment sword, the drive division passes through the guide part and is connected with C type knife rest.

Preferably, the slag scraping knife is fixed on the C-shaped knife rest through a threaded bolt and a pressing plate, and a clamping head is fixed on one side, deviating from the inner arc notch, of the C-shaped knife rest.

Preferably, the guide part comprises a dovetail planker and a dovetail seat, the dovetail planker is connected to the dovetail seat in a sliding mode, and one end of the dovetail planker is fixedly connected with the chuck through a bolt.

Preferably, the driving part comprises an air cylinder, and the end part of a piston rod of the air cylinder is connected with one end, far away from the C-shaped tool rest, of the dovetail carriage through a connector.

Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the dovetail planker is pushed by the cylinder to enable the C-shaped tool rest to drive the slag scraping tool to contact with the oxygen lance, so that the purpose of cleaning steel slag adhered to the surface of the oxygen lance is achieved when the oxygen lance is lifted, normal use of the oxygen lance is guaranteed, and consumption cost is reduced.

In the figure: 1-a slag scraping component; 2-a cylinder; 3-connecting the hands; 4-dovetail base; 5-dovetail planker; 6-clamping the head; 7-C type tool rest; 8-slag scraping knife.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Examples

As shown in fig. 1-3, the oxygen lance slag scraper for the cast steel converter comprises two slag scraping assemblies 1 which are identical in structure and symmetrically arranged, wherein each slag scraping assembly 1 comprises a driving part, a guiding part and a slag scraping part, each slag scraping part comprises a C-shaped tool rest 7, a slag scraping knife 8 is fixed at the inner arc of each C-shaped tool rest 7, and the driving part is connected with the C-shaped tool rest 7 through the guiding part.

In this embodiment, the slag scraping knife 8 is fixed on the C-shaped knife rest 7 through a threaded bolt and a pressing plate, and a clamping head 6 is fixed on one side of the C-shaped knife rest 7 departing from the inner arc notch.

In this embodiment, the guide part includes a dovetail planker 5 and a dovetail seat 4, the dovetail planker 5 is connected on the dovetail seat 4 in a sliding manner, and one end of the dovetail planker 5 is fixedly connected with a chuck 6 through a bolt.

In this embodiment, the driving part includes a cylinder 2, and an end of a piston rod of the cylinder 2 is connected to one end of a dovetail carriage 5 far away from a C-shaped tool rest 7 through a catcher 3.

The utility model discloses a principle and advantage: according to the oxygen lance slag scraper for the cast steel converter, when the oxygen lance is used, the cylinders 2 in the left and right slag scraping assemblies 1 are started, the cylinders 2 work to push the dovetail planker 5 to approach the oxygen lance along the trend of the dovetail base 4 through the piston rod, the dovetail planker 5 moves to synchronously drive the C-shaped tool rests 7 to approach the oxygen lance through the clamping heads 6, namely the two C-shaped tool rests 7 approach each other and surround the outer side of the oxygen lance until the slag scraping tools 8 contact the oxygen lance, and when the oxygen lance is lifted, the slag scraping tools 8 scrape off steel slag adhered to the oxygen lance body, so that the purpose of cleaning the steel slag adhered to the surface of the oxygen lance is achieved, the normal use of the oxygen lance is ensured, and the consumption cost is reduced;

after the slag scraping is finished, the dovetail planker 5 is driven by the cylinder 2 to be far away from and reset to the oxygen lance along the trend of the dovetail seat 4, so that the C-shaped tool rests 7 are synchronously driven to be far away from and reset to the oxygen lance, namely, the two C-shaped tool rests 7 are far away from each other, and the next time of slag scraping of the oxygen lance is performed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
