Abstract
The utility model belongs to the device of steel mill ladle nozzle protection cast; a kind of filling sandpipe positioner particularly; be included in the filling sandpipe arranging on ladle nozzle, axial affixed backstay on the outer wall of filling with the sandpipe port of export, it is 130-160mm that backstay stretches out the length of filling with sandpipe mouth.The utility model is simple in structure, convenient and practical, when steel-making is filled with stuffing sand in manual operation, can will fill with sandpipe location, without the artificial height of filling with sandpipe of adjusting, the stuffing sand shape of filling with after sand can reach technological requirement, can save the use amount of stuffing sand, improve ladle from flow rate.
Description
Technical field
The utility model belongs to the device, particularly a kind of filling sandpipe positioner of steel mill ladle nozzle protection cast.
Background technology
During steel mill pour steel, ladle is relevant with quality and the filling sand shape of stuffing sand from flow rate, the drainage sand that steel mill is used is filled with sandpipe, because of without positioner, when stuffing sand is filled with in manual operation, when filling with sand because the mouth of a river completely after, fill with sandpipe surplus material and must mention filling sandpipe, drainage sand is trickled down does not need region, and can not form the shape after the required stuffing sand of technique has been filled with, and causes cooperative job personnel to increase operation inconvenience, cause drainage sand waste, being affected from flow rate of ladle.
Utility model content
The purpose of this utility model is to provide a kind of filling sandpipe positioner, it is simple in structure, convenient and practical, when steel-making is filled with stuffing sand in manual operation, can will fill with sandpipe location, without the artificial height of filling with sandpipe of adjusting, the stuffing sand shape of filling with after sand can reach technological requirement, can save the use amount of stuffing sand, improve ladle from flow rate.
The purpose of this utility model is achieved in that a kind of filling sandpipe positioner, is included in the filling sandpipe arranging on ladle nozzle, axial affixed backstay on the outer wall of filling with the sandpipe port of export, and it is 130-160mm that backstay stretches out the length of filling with sandpipe mouth.
The utility model is being filled with the support bar of the affixed specific length of the port of export of sandpipe, when sand is filled with in operation, to fill with sandpipe and insert ladle nozzle, because support bar first contacts ladle nozzle, so filling with the space of leaving certain distance between sandpipe and the mouth of a river, after the mouth of a river being filled when filling with sand, without artificial adjustment, fill with sandpipe height, the stuffing sand shape of filling with after sand reaches technological requirement, just can stop at any time adding of stuffing sand, not only reduce unnecessary waste of material, and improve steel ladle self-flow rate.
The good effect that the utility model produces:
Fill with sandpipe positioner convenient and practical
1. the operation of the filling stuffing sand of steel-making does not need cooperation personnel, only needs people's once-through operation just can complete.
2. stuffing sand use amount has reduced by 1/3, and steel ladle self-flow rate has raise and 2% reached more than 97%.
3. alleviated site operation personnel's labour intensity.
The utility model is simple in structure, convenient and practical, when steel-making is filled with stuffing sand in manual operation, realized and will fill with sandpipe location, without the artificial height of filling with sandpipe of adjusting, the stuffing sand shape that makes to fill with after sand reaches technological requirement, saved the use amount of stuffing sand, improved ladle from flow rate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is structural representation of the present utility model.
The specific embodiment
A filling sandpipe positioner, as shown in Figure 1, is included on ladle nozzle 1 the filling sandpipe 2 arranging, axial affixed backstay 3 on the outer wall of filling with sandpipe 2 ports of export, and it is 130-160mm that backstay 3 stretches out the length of filling with sandpipe mouth.Axial uniform affixed backstay 3 on the outer wall of filling with sandpipe 2 ports of export, the quantity of backstay 3 be 1-3 only.The quantity of backstay 3 is 2.
Claims (3)
1. a filling sandpipe positioner, be included in the upper filling sandpipe (2) arranging of ladle nozzle (1), it is characterized in that: axial affixed backstay (3) on the outer wall of filling with sandpipe (2) port of export, it is 130-160mm that backstay (3) stretches out the length of filling with sandpipe mouth.
