Abstract

The utility model relates to a brick-embedded converter mouth with a steel tapping side thereof. Firebricks are embedded on the inner surface of the diamerter on the steel tapping side of the converter mouth, and the firebricks are laid on the inner wall of the diameter on the steel tapping side of the converter mouth. The brick-embedded converter mouth is a third-generation converter mouth, fire-resistant firebricks in various shapes are embedded on one surface on the steel tapping side of the converter mouth, so as to increase high-temperature resistance of one surface on the steel tapping side of the converter mouth, therefore, cast iron consumption of one surface on the steel tapping side of the converter mouth is reduced so as to prolong the service life of the converter mouth.

Description

Edge brick converter mouth

Technical field

The utility model relates to metallurgical production, particularly a kind of edge brick converter mouth of steel-making converter.

Background technology

Converter mouth is one of important spare part of steel-making converter, and variety of issue appears in fire door easily in steelmaking process, thereby influences the normal operation of steel-making converter, and the consumption of converter mouth is bigger.

The steel-making converter fire door is divided into cast iron fire door and welding fire door.The cast iron fire door is divided into pre-buried cooling tube furnace water-cooling mouth and plain cast iron fire door; The welding fire door generally all is a furnace water-cooling mouth.Current, more because of the problem that the welding fire door occurs, though domestic part steel-making enterprise is still using, domestic most of steel-making enterprise has all been used the cast iron fire door instead.

The cast iron fire door is longer work-ing life, water-cooled cast iron fire door particularly, and longer service life is on average made steel heat about 10,000 stoves.Yet the cast iron fire door still exists some problems, and the one side scaling loss of fire door tapping side is serious, and plain cast iron fire door tapping side one side scaling loss is even more serious, and water-cooled cast iron fire door scaling loss situation is quite a lot of, but some furnace water-cooling mouth tapping side one side can be burnt till plum blossom shape.More than a series of problems had a strong impact on work-ing life of cast iron fire door.

The utility model content

Task of the present utility model provides a kind of improved edge brick converter mouth, and it has solved above-mentioned steel-making converter fire door, and especially the scaling loss that exists of cast iron fire door is serious and have a strong impact on problem such as cast iron fire door work-ing life.

Technical solution of the present utility model is as follows:

A kind of edge brick converter mouth, it is provided with fire door tapping side, and the circle footpath internal surface of described fire door tapping side studs with refractory brick, and refractory brick is laid on the circle footpath inwall of fire door tapping side.

Edge brick converter mouth of the present utility model is a third generation converter mouth, be the refractory brick that simultaneously tumbles in resistant to elevated temperatures different shape in converter mouth tapping side, to increase the resistance to elevated temperatures of converter mouth tapping side one side, reduced the cast iron consumption of fire door tapping side one side thus, thus the work-ing life of improving converter mouth.

Description of drawings

Fig. 1 is a kind of structural representation of inlaying the brick converter mouth of the present utility model.

Fig. 2 is A-A sectional view that Fig. 1 inlays the brick converter mouth.

Embodiment

Referring to Fig. 1 and Fig. 2, the utility model is a kind of edge brick converter mouth, and it is provided with fire door tapping side 1, and internal surface studs with resistant to elevated temperatures refractory brick 2 in the circle footpath of fire door tapping side 1.As shown in FIG., many blocks of refractory brick 2 are laid on the circle footpath inwall of fire door tapping side 1.

Simultaneously tumble in the resistant to elevated temperatures refractory brick of different shape in cast iron fire door tapping side,, reduce the cast iron consumption of fire door tapping side one side in order to increase the resistance to elevated temperatures of cast iron fire door tapping side one side, thus the work-ing life of improving the cast iron fire door.

Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.

Claims

1. edge brick converter mouth, it is provided with fire door tapping side, it is characterized in that, and the circle footpath internal surface of described fire door tapping side studs with refractory brick, and refractory brick is laid on the circle footpath inwall of fire door tapping side.
