Abstract

The utility model relates to a steel-pack stuffing sand efflux device which includes a sand receiving hopper, a long handle which is fixed at the sand receiving handle. The utility model is characterized in that the sand receiving hopper is inserted with a strawboard sand dividing plate whose central angle is 60-160 degrees and whose height is 1.5-2 times of that of the sand receiving hopper. The utility model has a simple structure, is convenient to be operated, solves the space restriction of the efflux of the stuffing sand, avoids the burning problem of the operators, and improves the work efficiency.

Description

Ladle draining sand effluxes device

Technical field

The utility model relates to a kind of ladle draining sand and effluxes device.

Background technology

In the metallurgical continuous casting production process; for preventing that drainage sand from injecting in the tundish with molten steel; pollute molten steel; iron and steel enterprise generally adopts the strawboard cap to realize effluxing of drainage sand at present; but improvement along with the cast steel technology; for realizing non-oxidation protection cast; the length of the long sleeve pipe of ladle that extended, thus the space of strawboard cap occupied, and the strawboard cap can't be placed on the original position by the restriction in space; drainage sediment outflow weak effect; ladle is opened and is watered directly injection tundish of back, and the drainage sand that enters tundish can not float again fully, and part remains in the molten steel; the severe exacerbation steel quality causes waste product because of there is inclusion defect in the surface when producing cold-reduced sheet.

Summary of the invention

The utility model purport is the above-mentioned deficiency that overcomes existing strawboard cap, provide a kind of safe, realize the outer arranging device of ladle draining sand that drainage sand effluxes fast.

For achieving the above object, the utility model adopts following scheme:

The device that this ladle draining sand effluxes comprises and connects sand hopper, nigger, nigger is fixed on and connects on the sand hopper, it is characterized in that connecing the sand hopper interpolation, with connecing the cross section that sand hopper is complementary be the strawboard sub-sand plate of arc, and the central angle of strawboard sub-sand plate is 60 °～160 °; The height of strawboard sub-sand plate is to connect 1.5～2 times of sand hopper.

Compare of the present utility model having the following advantages with existing strawboard cap:

1 strawboard sub-sand plate is to utilize strawboard to meet the inflammable characteristics of fire, that has realized drainage sand effluxes and avoided operating personnel's burn and scald problem, and solved strawboard cap sand removing device because of the space inadequately can't sediment outflow a difficult problem.

The sediment outflow efficient of 2 the utility model and strawboard cap compares, and efficient of the present utility model has improved about 10%, makes cold rolled plate clip surface percent defective drop to 0.29% by 0.58%, obtains remarkable economic efficiency.

Description of drawings

Fig. 1: structural representation of the present utility model.

Among the figure: 1, connect sand hopper, 2, nigger, 3, strawboard sub-sand plate.

The specific embodiment:

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in detail: show as Fig. 1, the device that ladle draining sand effluxes comprises and connects sand hopper 1, nigger 2, connect sand hopper 1 and be the infundibulate of lower end closed, be welded by steel plate is curling, nigger 2 is fixed on and connects on the sand hopper 1, and inserting with connecing the cross section that sand hopper 1 is complementary in connecing sand hopper 1 is that the strawboard sub-sand plate 3 of arc, the central angle of strawboard sub-sand plate 3 are 100 °; Highly for connecing 1.5 times of sand hopper 1.

Claims (1)

1, a kind of ladle draining sand effluxes device, it comprises and connects sand hopper, nigger, nigger is fixed on and connects on the sand hopper, it is characterized in that: connecing the sand hopper interpolation, with connecing the cross section that sand hopper is complementary be the strawboard sub-sand plate of arc, the central angle of strawboard sub-sand plate is 60 °～160 °, and the height of strawboard sub-sand plate is to connect 1.5～2 times of sand hopper.
