Abstract

The utility model discloses a central pipe brick, which is mainly used for steel ingot casting. The central pipe brick comprises a brick body, and the brick body is provided with holes. The central pipe brick is characterized in that: the brick body is frustum-shaped, the outside diameter of one end is 230 millimeters, the outside diameter of the other end is 170 millimeters, and the height is 250 millimeters. The contact face of the bottom central pipe brick and a brick cup is enlarged, the external pressure resistance of the seam allowance of the bottom central pipe brick is enhanced, wobble and shift of a central casting pipe and damage of the seam allowance are reduced, and molten steel leakage during casting is avoided; and when the central pipe is lowered and the bottom central pipe brick is extruded with the brick cup, the seam allowance is not easily damaged. During transportation, the bottom central pipe brick is not easily shifted or the seam allowance is not easily damaged.

Description

Pipe brick in a kind of

Technical field:

The utility model is mainly used in ingot steel casting, is specifically related to a kind of middle pipe brick.

Background technology:

Fig. 1, Fig. 2 are the structure charts of existing middle pipe brick.In the STEELMAKING PRODUCTION process, ingot mould is when being equipped with mould, overhead traveling crane is being hung feed trumpet and is being descended, middle pipe brick block-by-block from top to bottom is inserted in feed trumpet successively, because middle pipe brick all is the cylinder barrel shape, the middle pipe brick at the end is relative less with the brick cup contact-making surface on being installed in wharve, pipe brick and brick cup rim of the mouth contact-making surface are horizontal plane and vertical plane simultaneously, the critical external compressive resistance ability is relatively poor, in the time of near managing brick in the feed trumpet decline arrival bottommost, the feed trumpet of hanging because of overhead traveling crane easily takes place to be offset or to rock, brick very easily depart from by run-off the straight or rim of the mouth and the brick cup rim of the mouth that is installed on the wharve at the bottom of the middle pipe of bottommost, after depart from inclination or rim of the mouth, produce the slit between the rim of the mouth, when cast, molten steel takes place and run leakage.

Summary of the invention:

In order to strengthen in the bottommost pipe brick and to be installed in surely closing of brick cup on the wharve, strengthen the critical external compressive resistance ability in pipe brick rim of the mouth in the bottom, the inclination, skew and the rim of the mouth that prevent pipe brick at the end are damaged, avoid molten steel in the casting process to run and leak, the utility model provide a kind of in the pipe brick.

The utility model comprises the brick body, and the brick body is provided with the hole, and the profile that it is characterized in that the brick body is a taper type, and wherein the external diameter of an end is 230mm, and the external diameter of the other end is 170mm, highly is 250mm.

The utility model has increased the contact-making surface of managing brick and brick cup in the bottom, strengthened the critical external compressive resistance ability in pipe brick rim of the mouth in the bottom, reduced rocking and skew and rim of the mouth damage of feed trumpet, having avoided the molten steel in the casting process to run leaks, in middle pipe decline process, when extruding took place for pipe brick and brick cup in the bottom, the rim of the mouth was not fragile.Managing also difficult generation skew of brick or rim of the mouth in transportation in the bottom damages.

Description of drawings:

Fig. 1 is the structure chart (axially analysing and observe) of existing middle pipe brick.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the structure chart (axially analysing and observe) of the utility model embodiment.

Among the figure, 1, the brick body, 2, fin, 3, groove, 4, the hole.

The specific embodiment:

Embodiment: shown in Figure 3, present embodiment comprises brick body 1, and brick body 1 is provided with hole 4, and the aperture is 100mm, the profile of brick body 1 is a taper type, and wherein the external diameter of an end is 230mm, and the external diameter of the other end is 170mm, highly be 250mm, an end of brick body is provided with fin 2, and the other end is provided with groove 3.

Claims

1. manage brick in one kind, comprise the brick body, the brick body is provided with the hole, and the profile that it is characterized in that the brick body is a taper type, and wherein the external diameter of an end is 230mm, and the external diameter of the other end is 170mm, highly is 250mm.
