Abstract

The utility model relates to the positioner that a kind of ladle nozzle adds drainage agent, it is characterized in that: it comprises brick cup (3), adding tube (4) and positioning pipe (5), this positioner is arranged on the mouth of a river (2) of steel ladle (1), described brick cup (3) is fixed on the inwall of the mouth of a river (2), through hole in the middle of described brick cup (3) is wide at the top and narrow at the bottom, described adding tube (4) is arranged at directly over brick cup (3), the internal diameter of described positioning pipe (5) is greater than the external diameter of adding tube (4), the bottom of described adding tube (4) to be inserted in positioning pipe (5) and to be welded and fixed with it, the two ends, left and right of described positioning pipe (5) are close in the upper inside wall of brick cup (3), and the tube wall of positioning pipe (5) has eight apertures.The positioner that this ladle nozzle adds drainage agent can prevent steel pipe from impacting slide plate at the bottom of the mouth of a river, preventing residue from falling into drainage agent, improves drainage agent and adds compactness, improve ladle self-opening rate.

Description

Ladle nozzle adds the positioner of drainage agent

Technical field

The utility model relates to the positioner that a kind of ladle nozzle adds drainage agent, belongs to technical field of ferrous metallurgy.

Background technology

It is electric furnace and pneumatic steelmaking two kinds of methods that current international and domestic main flow makes steel the method for making steel taked in batches, no matter take which kind of steel-making scheme, molten steel all must be transferred to ladle (being commonly called as large bag) from converter or electric furnace, or takes to continuous casting after refining, or directly after Argon to continuous casting.During cast, the moment stuffing sand that steel ladle slide board is opened needs under the static pressure effect of molten steel, to flow out ladle along the mouth of a river, molten steel is taken advantage of a situation outflow, be called that ladle " is opened " certainly, otherwise the moment stuffing sand that slide plate is opened can not flow out along the mouth of a river under the static pressure effect of molten steel, molten steel can not flow out, then need to pass into purity oxygen by oxygen lance stuffing sand is boiled thus molten steel can be flowed out along the mouth of a river enter tundish, complete casting process.

Ladle nozzle adds jettisoning method, the elongated steel pipe of employing that has of the employing that has of drainage agent and imports, but all can not accurately locate interpolation drainage agent, and the compactness causing drainage agent to add is lower, reduces the self-opening rate of ladle.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and provide one to prevent steel pipe from impacting slide plate at the bottom of the mouth of a river, preventing residue from falling into drainage agent, improve drainage agent and add compactness, the ladle nozzle improving ladle self-opening rate adds the positioner of drainage agent.

The purpose of this utility model is achieved in that

The utility model ladle nozzle adds the positioner of drainage agent, comprise brick cup, adding tube and positioning pipe, this positioner is arranged on the mouth of a river of steel ladle, described brick cup is fixed on the inwall at the mouth of a river, through hole in the middle of described brick cup is wide at the top and narrow at the bottom, described adding tube is arranged at directly over brick cup, the internal diameter of described positioning pipe is greater than the external diameter of adding tube, the bottom of described adding tube to be inserted in positioning pipe and to be welded and fixed with it, the two ends, left and right of described positioning pipe are close in the upper inside wall of brick cup, and the tube wall of positioning pipe have eight apertures.

The beneficial effects of the utility model are:

Adding tube is fixed on the center at the mouth of a river by the positioner of this ladle nozzle interpolation drainage agent, be evenly distributed when center, the mouth of a river is added towards periphery when can ensure that drainage agent adds, and drainage agent is when adding, positioning pipe is near the top at the mouth of a river, adding tube would not grazing to the mouth of a river and sled surface, be conducive to improving mouth of a river life-span and security reliability, the surrounding of positioning pipe near mouth of a river when drainage agent adds simultaneously, can prevent the residue above brick cup from dropping in drainage agent, realizing drainage agent adds clean, fine and close, prevent drainage agent from oozing slag sintering, improve ladle to open and water self-opening rate.

Accompanying drawing explanation

Fig. 1 is the structural representation that the utility model ladle nozzle adds the positioner of drainage agent.

Fig. 2 is the structural representation at mouth of a river place in Fig. 1.

Fig. 3 is the A portion enlarged drawing of Fig. 2.

Wherein: steel ladle 1, the mouth of a river 2, brick cup 3, adding tube 4, positioning pipe 5.

Detailed description of the invention

See Fig. 1 to Fig. 3, the utility model relates to the positioner that a kind of ladle nozzle adds drainage agent, comprise brick cup 3, adding tube 4 and positioning pipe 5, this positioner is arranged on the mouth of a river 2 of steel ladle 1, described brick cup 3 is fixed on the inwall at the mouth of a river 2, through hole in the middle of described brick cup 3 is wide at the top and narrow at the bottom, described adding tube 4 is arranged at directly over brick cup 3, the internal diameter of described positioning pipe 5 is slightly larger than the external diameter of adding tube 4, the bottom of described adding tube 4 to be inserted in positioning pipe 5 and to be welded and fixed with it, the two ends, left and right of described positioning pipe 5 are close on the upper wider inwall of brick cup 3, and the tube wall of positioning pipe 5 has eight apertures, for weight reduction with ventilative.

When this ladle nozzle adds the positioner interpolation drainage agent of drainage agent, first adding tube 4 is dropped to bottom brick cup 3 and the mouth of a river 2, positioning pipe 5 is made to be pressed on the upper wider inwall of brick cup 3, then drainage agent is added from adding tube 4 top, and then slowly lift adding tube 4, make to fill it up with drainage agent in brick cup 3 and the mouth of a river 2.

Claims
