Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of ore -smelting furnace, especially relates to a ore -smelting furnace eye repairing tool. BACKGROUND

[0002] In metallurgical industry ore -smelting furnace is one of its core equipment, ore -smelting furnace is also called arc furnace or resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent and solvent etc. raw materials, mainly produces ferrosilicon, manganese iron, chromium iron, tungsten iron, silicon manganese alloy etc. ferroalloy.

[0003] Ore -smelting furnace eye is a part of ore -smelting furnace body hearth, and its main function is just to discharge high-temperature melt, and ensure the smooth progress of smelting process. In the use process of ore -smelting furnace, the eye part is subjected to impact and erosion for a long time, and is prone to damage, which affects the normal discharge of melt, and therefore needs to be repaired regularly. In the process of repairing the eye, the staff usually first cleans the residual slag on the inner wall of the eye, and then fills the damaged and incomplete eye with electrode paste, and in this process, since there is no special repairing tool, the repairing time is long, the repairing operation efficiency is low, and the size of the repaired eye is deviated, not enough regular, thereby affecting the subsequent normal of the eye. SUMMARY

[0004] The utility model aims at providing a ore -smelting furnace eye repairing tool, and overcomes the insufficient of prior art, and effectively solves the existing problem of low efficiency of eye repair.

[0005] The utility model relates to a ore -smelting furnace eye repairing tool, including sleeve, install the support on the bottom wall of sleeve, install the concave clasp at the bottom of support, insert the tubular mould in the sleeve, install the guard piece in the inner end coaxial of tubular mould.

[0006] Further, the first screw hole is formed in the bottom wall of the concave clasp, and the first bolt is screwed in the first screw hole.

[0007] Further, the support is V-shaped.

[0008] Further, the second screw hole is formed in the sleeve, and the second bolt is screwed in the second screw hole.

[0009] Further, the inner circumferential surface of the sleeve and the outer circumferential surface of the tubular mould are slidingly attached.

[0010] The utility model discloses a beneficial effect: the simple structure of the repair tool is convenient to operate, through the tubular mould support in the furnace eye that needs to repair, make the repair range can be limited, thereby avoid the furnace eye repair and produce the size deviation of bigger, make the furnace eye after repair is more regular, and the repair time is shorter, and the repair operation efficiency improves, guarantees the normal use of furnace eye later. BRIEF DESCRIPTION OF DRAWINGS

[0011] Fig. 1 It is the front view of the utility model;

[0012] Fig. 2 It is the partial sectional view of left view of the utility model;

[0013] In the drawing, 1 sleeve, 2 support, 3 concave clamping, 4 tubular mould, 5 guard piece, 6 first bolt, 7 second bolt, 8 bottom baffle, 9 side baffle, 10 submerged arc furnace, 11 furnace eye, 12 gap. DETAILED DESCRIPTION

[0014] In order to have more clear understanding to the technical features, object and effect of the utility model, now the specific implementation of the utility model is explained with the drawings:

[0015] As Figs. 1-2 Shown, a submerged arc furnace furnace eye repair tool, including sleeve 1, install support 2 on the bottom wall of sleeve 1, install concave clamping 3 on the bottom end of support 2, insert tubular mould 4 in sleeve 1, install guard piece 5 in the inner end of tubular mould 4, open first screw hole on the bottom wall of concave clamping 3, screw first bolt 6 in first screw hole, support 2 is V-shaped, open second screw hole on sleeve 1, screw second bolt 7 in second screw hole, the inner circumferential surface of sleeve 1 and the outer circumferential surface of tubular mould 4 slide fit.

[0016] Specifically, by the tubular mould 4 support in the furnace eye 11 that needs to repair, make the repair position can be limited, thereby avoid the furnace eye 11 repair and produce the size deviation of bigger.

[0017] In actual use, the two side baffles 9 and the bottom baffle 8 of the original furnace surround the furnace eye 11; when repairing, first, the concave clasp 3 is inserted on the outer edge of the bottom baffle 8, then the position is adjusted so that the sleeve 1 can be substantially coaxial with the furnace eye 11, after the first bolt 6 is locked, the concave clasp 3 can be further fixed on the bottom baffle 8 to prevent it from moving, at this time, the tubular mold 4 is inserted into the furnace eye 11 from the inside of the furnace, and the outer end of the tubular mold 4 is inserted into the sleeve 1, after continuously pushing the tubular mold 4, the baffle piece 5 is attached to the inner side wall of the furnace, thereby preventing the filling material from flowing into the furnace, after the second bolt 7 is locked, the tubular mold 4 can be further fixed on the sleeve 1 to prevent it from moving, at this time, the formwork work before repairing is completed, the staff fills the repairing electrode paste into the repairing gap 12 between the tubular mold 4 and the furnace eye 11 from the outside of the furnace, then the protective layer is tied with the casting material, after the repairing is completed, the tubular mold 4 is withdrawn from the sleeve 1 and the furnace eye 11, and the remaining part of the repairing tool is disassembled, so that the circular furnace eye 11 with small size deviation and regular shape can be repaired.

[0018] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
