Abstract
The utility model discloses a steelmaking alloy feed delivery device which comprises a feed delivery pipe 2 which is arranged at the bottom of a hopper and a feed delivery pipe 4 which is arranged at the bottom of an overall hopper, wherein, the feed delivery pipe 2 is communicated with the overall hopper; the other end of the feed delivery pipe 4 is communicated with a fire hole; the feed delivery pipe 2 and the feed delivery pipe 4 are provided with elbows; grooves 5 are arranged on the elbows; notches of the grooves 5 and inlets of the feed delivery pipes are in the same central line. Therefore, when alloys are added into a steelmaking furnace, the alloys impact downwards to the elbows from the hopper, and metals which are accumulated in the grooves of the elbows are impacted and rubbed, instead of the interior wall surfaces on the elbows of the feed delivery pipes. The utility model can greatly prolong service life of the feed delivery pipes.
Description
Technical field:
The utility model relates to the metal smelt field, is specifically related to steel-making alloy feeding device in the metal smelt field.
Background technology:
In steel-making, especially refine in the special steel process, add chromium, nickel, multiple alloy such as violent.At present, the method that adds alloy is to be provided with total hopper above body of heater, some alloy hoppers and conveying pipeline thereof are arranged in around total hopper, be subjected to the restriction of site location, most of conveying pipelines can't vertically with the hopper baseplane lead to total hopper, the conveying pipeline that comprises total feed hopper bottom also can't with the vertical fire door that leads in total hopper baseplane, the conveying pipeline bending could to be imported alloy in total hopper, imported in the stove then inevitably.Because conveying pipeline exists elbow, that is to say when alloy when hopper sweeps away, will inevitably clash into the lower wall surface of the elbow that rubs, thereby this wall becomes the weak link of conveying pipeline, often being broken needs to repair, the ordinary production of influence steel-making, the production cost of increase enterprise.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of steel-making alloy feeding device, overcomes the defective that the conveying pipeline wall is often broken in the prior art.
The utility model is achieved through the following technical solutions.
Steel-making alloy feeding device comprises the conveying pipeline 2 that is arranged at feed hopper bottom, is arranged at the conveying pipeline 4 of total feed hopper bottom; Described conveying pipeline 2 is communicated with total hopper, and the other end of conveying pipeline 4 leads to fire door; Conveying pipeline 2, conveying pipeline 4 are provided with elbow, are provided with groove 5 in the elbow of conveying pipeline 2, conveying pipeline 4.
Described groove is arranged at the elbow exterior bottom, and its notch and conveying pipeline are positioned at inlet at the bottom of the hopper and conveying pipeline 4 and are positioned at inlet at the bottom of total hopper on same center line.The degree of depth of groove is greater than the alloy volume height.
Beneficial effect:
The utility model is owing to the exterior bottom with the conveying pipeline elbow is designed to groove, and the notch of groove is corresponding with the inlet of conveying pipeline, that is notch and conveying pipeline inlet is positioned on same the center line, therefore, when adding alloy to converter, alloy impacts downwards to the elbow from hopper, and what bump rubbed is the metal of being piled up in the elbow groove, rather than the lower wall surface of conveying pipeline elbow.
Use of the present utility model can guarantee that the lower wall surface of conveying pipeline can not rubbed by bump, thereby prolong the service life of conveying pipeline greatly.
Description of drawings:
Fig. 1 is the utility model connection status schematic diagram;
Fig. 2 is a conveying pipeline axial section schematic diagram.
The specific embodiment:
As shown in Figure 1, the utility model comprises the conveying pipeline 2 that is arranged at hopper 1 bottom, is arranged at the conveying pipeline 4 of total hopper 3 bottoms; Described conveying pipeline 2 is communicated with total hopper 3, and the other end of conveying pipeline 4 leads to fire door.As shown in Figure 1, 2, conveying pipeline 2, conveying pipeline 4 are provided with elbow, elbow exterior bottom at conveying pipeline 2, conveying pipeline 4 is provided with groove 5, and inlet and conveying pipeline 4 that its notch and conveying pipeline 2 are positioned at the bottom of the hopper are positioned at the inlet at 3 ends of total hopper on same center line.The degree of depth of described groove 5 is greater than alloy volume height (helping alloy is piled up in the groove 5), and as shown in Figure 2, the degree of depth of present embodiment further groove 5 is more than the twice of alloy volume height.
Still as shown in Figure 2, piled up many alloys in the described groove 5, when alloy impacts to the elbow downwards from hopper or total hopper once more, the bump friction be the metal of being piled up in the elbow groove, rather than the lower wall surface of conveying pipeline elbow.
