Abstract
The utility model relates to a middle package pushing off slag is opened and is watered pipe, including the cylinder sleeve pipe, be equipped with elongated hole in the lower part symmetry of cylinder sleeve pipe lateral wall, elongated hole follow the cylinder sleeve pipe down along the axial setting, cylinder sheathed tube upper portion symmetric connection holding rod. The outer diameter of the cylindrical sleeve is 105mm-110mm, and the length of the cylindrical sleeve is 280mm-300 mm. The length of the elongated hole is 170mm-180mm, and the width of the elongated hole is 12-18 mm. The length of the holding rod is 2.5-3.0 m. The utility model discloses effectively block that the sediment of package gets into the crystallizer in the middle of the heavy rail, open and water the pipe and use the back heavy rail and hinder the track rate and reduce 0.04%.
Description
Technical Field
The utility model relates to a continuous casting field, in particular to pouring basket pushing off slag and opening and watering pipe.
Background
Most of the casting pipes are pre-buried at the bottom of the tundish, the casting ring is sleeved outside the casting pipe, the liquid level slowly rises after the molten steel reaches the tundish, the casting ring slowly rises along with the molten steel, slag blocked by the casting ring enters the casting pipes, and the molten steel enters the crystallizer from the casting pipes.
The heavy rail tundish is used for preventing external foreign matters from being drawn into the crystallizer to influence the quality of a casting blank, and has no slag wall and no embedded casting opening pipe. When the ladle cover falls off or the ladle bottom is not clean, slag can be generated to influence the quality of the continuous casting billet.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a pouring basket pushing off slag casting pipe, improve the casting blank quality.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a middle package pushing off slag opens and waters pipe, includes the cylinder sleeve pipe, along a plurality of elongated hole of circumference method equipartition in the lower part of cylinder sleeve pipe lateral wall, elongated hole follow cylinder sleeve pipe down along the axial setting, the holding rod is connected to the upper portion symmetry of cylinder sleeve pipe.
The outer diameter of the cylindrical sleeve is 95mm-110mm, and the length of the cylindrical sleeve is 250mm-300 mm.
The length of the elongated hole is 170mm-180mm, and the width of the elongated hole is 12-18 mm.
The length of the holding rod is 2.5-3.0 m.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses effectively block that the sediment of package gets into the crystallizer in the middle of the heavy rail, open and water the pipe and use the back heavy rail and hinder the track rate and reduce 0.04%.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: cylindrical sleeve 1, elongated hole 2, holding rod 3.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
as shown in figure 1, the tundish slag-stopping pouring pipe comprises a cylindrical sleeve 1, wherein the outer diameter of the cylindrical sleeve is 95mm-110mm, and the length of the cylindrical sleeve is 250mm-300 mm. The lower part of the side wall of the cylindrical sleeve 1 is symmetrically provided with elongated holes 2, the elongated holes 2 are arranged along the axial direction from the lower part of the cylindrical sleeve, the length of the elongated holes is 170mm-180mm, and the width of the elongated holes is 12-18 mm.
The upper part of the cylindrical sleeve 1 is symmetrically connected with a holding rod 3, and the length of the holding rod is 2.5-3.0 m.
Examples
The utility model provides a middle package pushing off slag is opened and is watered pipe, includes cylinder sleeve pipe 1, and cylinder sleeve pipe 1's material is iron, and cylinder sleeve pipe's external diameter 108mm, length are 280 mm. The lower part symmetry at cylinder sleeve 1 lateral wall is equipped with elongated hole 2, and elongated hole 2 sets up along the axial from cylinder sleeve lower edge, and elongated hole's length 180mm, elongated hole's width 15 mm.
The upper part of the cylindrical sleeve 1 is symmetrically connected with a holding rod 3, and the length of the holding rod is 2.5 m.
After the tundish car reaches a pouring position, the open pouring pipe is placed into the nozzle brick cup from a ladle cover hole above the nozzle eye, molten steel enters the tundish and flows into the crystallizer from the elongated holes on the two sides of the open pouring pipe, impurities are effectively prevented from being drawn into the crystallizer by the pipe wall outside the elongated holes, and when the molten steel does not pass through the open pouring pipe, the open pouring pipe is rapidly melted by the molten steel.
The above is only the basic principle of the present invention, not to the present invention makes any limitation, all the bases of the present invention are the same changes and modifications to the above, all within the scope of the protection scheme of the present patent technology.
