Abstract

The utility model relates to a ladle package bottom structure, it includes: including nozzle brick, impact brick, air brick and fill the casting material layer around nozzle brick, impact brick and air brick, its characterized in that: the top surface of the impact brick is higher than that of the nozzle brick, and a pouring material layer between the impact brick and the nozzle brick is provided with a diversion trench.

Description

Ladle bottom structure

Technical Field

The utility model relates to a ladle, more specifically say and relate to a ladle package bottom structure.

Background

The existing ladle is arranged at the bottom of the ladle, the top surfaces of a nozzle brick and an impact brick and a casting material layer are on the same plane, about 5-10 tons of molten steel can be remained at the bottom of the ladle after the molten steel is cast every time, and the molten steel remained at the bottom of the ladle can only be poured out together with ladle slag, so that the yield of the molten steel is low, great waste is caused, and the energy consumption is increased undoubtedly and the cost is increased because the energy consumption of molten steel refining is large.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a can let the ladle bottom structure of the outflow from the ladle mouth of a river of molten steel as much as possible.

In order to achieve the above object, the utility model provides a ladle package bottom structure, it includes: including nozzle brick, impact brick, air brick and fill the casting material layer around nozzle brick, impact brick and air brick, its characterized in that: the top surface of the impact brick is higher than that of the nozzle brick, and a pouring material layer between the impact brick and the nozzle brick is provided with a diversion trench.

The utility model discloses further technical characteristic is:

the bottom of the diversion trench is in a slope shape, the diversion trench smoothly transits from the top surface of the impact brick to the top surface of the nozzle brick, and the width of the diversion trench is equal to the outer diameter of the top surface of the nozzle brick.

The slope of the bottom of the diversion trench relative to the bottom surface of the ladle is 3-10 degrees.

The slope of the bottom of the diversion trench relative to the bottom surface of the ladle is 3 degrees.

The slope of the bottom of the diversion trench relative to the bottom surface of the ladle is 5 degrees.

The slope of the bottom of the diversion trench relative to the bottom surface of the ladle is 10 degrees.

The utility model has the advantages that:

because the utility model discloses in strike the brick top surface and be higher than the mouth of a river brick top surface, just strike the brick with pouring material layer between the mouth of a river brick is provided with the guiding gutter, and molten steel does not have unnecessary molten steel to persist because near mouth of a river brick relief is low when pouring steel like this, has improved the molten steel yield.

Drawings

Fig. 1 is a resulting cross-sectional view of an embodiment according to the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1;

fig. 3 is a top view of the structure of the embodiment shown in fig. 1.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, a ladle bottom structure includes: including nozzle brick 1, impact brick 2, air brick 3 and fill 4, its characterized in that at the castable layer around nozzle brick 1, impact brick 2 and air brick 3: the top surface of the impact brick is higher than that of the nozzle brick, and a pouring material layer between the impact brick 2 and the nozzle brick 3 is provided with a diversion trench 5. The utility model discloses in, 5 bottoms of guiding gutter are slope form, along strikeing the smooth transition of brick top surface to the mouth of a river brick top surface, and the guiding gutter width equals with mouth of a river brick top surface external diameter, just the slope of the relative ladle bottom surface in guiding gutter bottom is 3 degrees.

In practical application, the slope of the bottom of the diversion trench relative to the bottom surface of the ladle can be set to be 5 degrees or 10 degrees.

While the invention has been described with reference to the above embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the above-described arrangements, including combinations of features disclosed herein either individually or in any combination as is evident from the below disclosure. These variants and/or combinations fall within the technical field of the present invention and are intended to be protected by the following claims.

Claims

1. The utility model provides a ladle package end structure, includes nozzle brick, impact brick, air brick and fills the casting material layer around nozzle brick, impact brick and air brick, its characterized in that: the top surface of the impact brick is higher than that of the nozzle brick, and a pouring material layer between the impact brick and the nozzle brick is provided with a diversion trench.

2. The ladle bottom structure of claim 1, wherein the bottom of the guide channel is sloped to smoothly transition from the top surface of the impact brick to the top surface of the nozzle brick, and the width of the guide channel is equal to the outer diameter of the top surface of the nozzle brick.
