Abstract
The utility model discloses oxygen lance slag-scraper tool aprons, wherein the oxygen lance slag-scraper consists of two sets of symmetric devices, each set comprising a tool apron, a scraper arranged on the lower part of the tool apron and a mobile device hinged with a plunger piston rod of a plunger cylinder. The utility model is characterized in that: one end of the tool apron is fixedly connected with the mobile device, and the other end of the tool apron is provided with a semi-circular notch, the inner side of the edge of the lower side of which is fixedly connected with the scraper. The utility model has an improved and integrated structure of the tool aprons, which greatly improves the stress of the tool aprons. Practice shows that the utility model, which has the advantages of low-malfunction rate, long service life, etc., can completely satisfy the production needs.
Description
Technical field:
The utility model relates to iron and steel and controls white silk, and the oxygen rifle draws together the slag device in being specifically related to make steel.
Background technology:
In converter or EAF Steelmaking Process, the slag in the smelting furnace can be bonded on the oxygen rifle, and oxygen rifle dry slag has not only worsened the Working environment of oxygen rifle, but also can have influence on work-ing life of oxygen rifle, therefore, in time removing the dry slag on the oxygen rifle, is indispensable link in the steelmaking process.Present oxygen rifle slag scraping device, its tool rest mostly is semicircle or similar semicircular annulus spline structure greatly, be connected with running gear by union lever, because of slag scraping device in drawing together the slag process, reactive force to slag is unbalanced, draws together slag power when big when needs, and the intensity of this semicircle tool rest can not adapt to requirement, often damage, need carry out heat maintaining.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of tool rest of Dreg Scraping Device of Oxygen Lance, and in drawing together the slag process, the whole force-bearing situation of tool rest is good, the intensity height, and that can satisfy the oxygen rifle draws together the slag requirement.
The utility model is achieved through the following technical solutions:
A kind of Dreg Scraping Device of Oxygen Lance tool rest, described Dreg Scraping Device of Oxygen Lance is made of two groups of symmetrical devices, every group of device comprise tool rest, be arranged at the running gear of drawing together cutter, being hinged with the plunger rod of plunger case of tool rest bottom, characteristics are that tool rest one end and running gear connect firmly, the other end is provided with semicircular notch, draws together the lower edge inboard that cutter is fixed on semicircular notch.
The radius of described semicircular notch is greater than oxygen rifle radius, and the radius of drawing together cutter blade circular arc line equals or is slightly larger than oxygen rifle radius.
The utility model compared with prior art has the following advantages:
The utility model is modified into one-piece construction with tool rest, and an end of tool rest is connected with running gear, and the other end is provided with semicircular notch, draws together the lower edge inboard that cutter is fixed on semicircular notch.Such design has improved the force-bearing situation of tool rest greatly, and through using proof, the utility model can satisfy the production needs fully.
The utlity model has advantages such as failure rate is low, long service life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to synoptic diagram.
Embodiment:
As shown in Figure 1, the utility model constitutes (Fig. 1 only provides one group of device) by two groups of symmetrical devices, every group of device comprise tool rest 1, be arranged at tool rest 1 bottom draw together cutter 4, with the running gear 2 that the plunger rod 5 of plunger case is hinged, also comprise the permanent seat 6 that is hinged with plunger rod 5.
As shown in Figure 1 and Figure 2, tool rest 1 one ends and running gear 2 connect firmly that (running gear 2 is provided with track.Not shown), the other end is provided with semicircular notch 3, draws together the lower edge inboard that cutter 4 is fixed on semicircular notch 3.
As shown in Figure 2, the radius of described semicircular notch 3 is greater than oxygen rifle radius, and the radius of drawing together cutter blade circular arc line equals or is slightly larger than oxygen rifle radius.
When the utility model needed work, the plunger rod 5 of plunger case promoted curved bars 7, and on a sea line, at this moment, 1 armful of the tool rest of two groups of devices is in oxygen rifle 8 peripheries until curved bar 7 and permanent seat 6, running gear 2, on carry oxygen rifle 8, draw together cutter and can implement draw together slag the oxygen rifle.
Claims (2)
1. Dreg Scraping Device of Oxygen Lance tool rest, described Dreg Scraping Device of Oxygen Lance is made of two groups of symmetrical devices, every group of device comprise tool rest, be arranged at the running gear of drawing together cutter, being hinged with the plunger rod of plunger case of tool rest bottom, it is characterized in that: tool rest (1) one end and running gear (2) connect firmly, the other end is provided with semicircular notch (3), draws together the lower edge inboard that cutter (4) is fixed on semicircular notch (3).
2. a kind of Dreg Scraping Device of Oxygen Lance tool rest as claimed in claim 1 is characterized in that: the radius of described semicircular notch (3) is greater than oxygen rifle radius, and the radius of drawing together cutter blade circular arc line equals or is slightly larger than oxygen rifle radius.
